A new report that provides a long-term view of the evolution of the world’s power markets suggests that by 2027 building new wind and solar will become cheaper than running existing coal and gas generators in many parts of the world. Between 2016 and 2040, Bloomberg New Energy Finance’s New Energy Outlook projects that $7.8 trillion will be invested in renewables globally.
“One conclusion that may surprise is that our forecast shows no golden age for gas, except in North America,” said report co-author Elana Giannakopoulou. “As a global generation source, gas will be overtaken by renewables in 2027. It will be 2037 before renewables overtake coal.”
The energy sector, which accounts for two-thirds of greenhouse gas emissions, will not change quickly enough to meet the Paris Agreement’s target for limiting global temperatures to “well below” 2 degrees Celsius below pre-industrial levels. According to the report, to meet this target, leaders must invest $13.1 trillion—$5.3 trillion more than the $7.8 trillion expected to be invested in renewables by 2040. This will presumably require further changes in technology and policy to increase the uptake of new low carbon investment to meet that target.
What happens with fossil fuel emissions, it says, will largely depend on choices made by the Asia-Pacific region that’s forecast to see major growth in wind, solar and coal.
By 2040, the study suggests energy storage market will be valued at $250 billion or more as battery costs are projected to fall and storage deployment rises. Utility-scale batteries are projected to become widespread in little more than a decade.
Greenland Ice Melt Points to Warming Feedback Loop
As news emerged that Arctic sea ice extent hit a record low in May, a study published in Nature Communications provided evidence that links melting ice in Greenland to so-called Arctic amplification or faster warming of the Arctic than the rest of the Northern Hemisphere as sea ice disappears. The study revealed that changing temperatures at the poles driven by global warming have the potential to affect the jet stream, causing it to bend further north than usual.
“If loss of sea ice is driving changes in the jet stream, the jet stream is changing Greenland, and this, in turn, has an impact on the Arctic system as well as the climate,” said lead author Marco Tedesco, a research professor at Columbia University’s Lamont-Doherty Earth Observatory. “It’s a system, it is strongly interconnected and we have to approach it as such.”
During July 2015, according to the study, a “cutoff high”—a relatively immobile region of high pressure—allowed sunny conditions to be sustained for many days over northwest Greenland, producing record melting there. The study suggests that the high was linked with a record-breaking northward departure of the mid-latitude jet stream, which is thought to result from the jet stream’s slowing due to a reduction in the temperature difference between polar latitudes and more temperate regions.
According to study co-author Edward Hanna, an earth scientist at the University of Sheffield in the United Kingdom, these cut-off highs are becoming more prevalent in the Arctic, and they may be here to stay because of climate change.
Record Temps Continue in May
Analysis by NASA’s Goddard Institute for Space Studies showed that Earth experienced its hottest May on record—1.67 degrees Fahrenheit above the 1951–1980 average. The data, according to the Daily Mail, showed 370 straight months of warm or warmer-than-average temperatures worldwide.
David Carlson, director of the U.N.’s World Climate Research Program, expressed concern about the records: “We are in uncharted territory. Exceptionally high temperatures. Ice melt rates in March and May that we don’t normally see until July. Once-in-a-generation rainfall events. The super El Nino is only partly to blame. Abnormal is the new normal.”

The Great Barrier Reef, which last year narrowly avoided being put on the World Heritage endangered list, is experiencing its worst bleaching in recorded history. According to the Great Barrier Reef Marine Park Authority, overall mortality of the reef is 22 percent, but along Lizard Island, off far north Queensland, it’s 93 percent. Coral bleaching is also occurring along the Maldives, Thailand, and Christmas Island.
By year’s end, what the National Oceanic and Atmospheric Administration (NOAA) has designated the third global coral bleaching in less than two decades, and the longest and most severe so far, will have killed 12,000 square kilometers of reefs and affected more than a third of the world’s corals.
Satellite data produced for The Guardian by Mark Eakin, head of NOAA’s Coral Reef Watch, reveals the increasingly widespread impact of ocean temperature increases on the Great Barrier Reef, where bleaching is predicted to become an annual event by 2020.
“While there was a considerable amount of variability—from El Niños and other things—there was an obvious upward trend in the data,” Eakin said. “So you’re looking at the background warming, which is having a major effect on the corals.”
Although coral bleaching is thought to result largely from abnormally high sea temperatures that kill marine algae crucial for coral health, a study published Tuesday in Nature Communications and based on a three-year experiment on a coral reef in the Florida Keys nuances that understanding. Its authors say that widespread coral deaths observed in recent decades are being caused by a combination of multiple local stressors that become lethal in the presence of higher temperatures.
“This makes it clear there’s no single force that’s causing such widespread coral deaths,” said study co-author Rebecca Vega Thurber of Oregon State University. “Loss of fish that help remove algae, or the addition of excess nutrients like those in fertilizers, can cause algal growth on reefs. This changes the normal microbiota of corals to become more pathogenic, and all of these problems reach critical levels as ocean temperatures warm.”
United States and India Announce Climate and Energy Agreements
On Tuesday, following a meeting with President Obama partly focused on climate change and energy, Indian Prime Minister Narendra Modi said his country, the world’s third-largest greenhouse gases producer, would ratify the Paris Agreement this year. The action is considered a key step in cementing the deal, which goes into effect 30 days after 55 nations representing 55 percent of all greenhouse gas emissions ratify it. To date, countries representing approximately 50 percent of global emissions have announced that they will submit legal documentation of their compliance with the deal, under which more than 190 nations agreed to keep global warming to within 2 degrees Celsius of pre-industrial levels and to pursue efforts to limit warming to 1.5 Celsius.
“Both leaders feel as if the collaboration between the two leaders was an important element of actually getting Paris successfully negotiated last December,” said Brian Deese, President Obama’s top climate change advisor. “They will both clearly endorse the importance of promoting full implementation of the Paris agreement.”
President Obama indicated that the speed with which the agreement could be brought into force would depend in part on securing “the climate financing that’s necessary for India to be able to embark on a bold vision for solar energy and clean energy” laid out by Modi.
Among the other climate and energy agreements the countries announced was a joint effort to adopt, this year, an amendment to the Montreal Protocol on the use of hydrofluorocarbons (subscription). That amendment would increase financial support to the protocol’s multilateral fund and contain an “aggressive phasedown schedule” for the potent greenhouse gas.
According to a White House fact sheet, other joint efforts include a $40 million program to provide capital for solar projects and a $20 million clean energy finance initiative.
India also agreed to a low greenhouse gas emissions development strategy.
Ontario Unveils Climate Plan with Carbon Market Funding
Yesterday, Ontario announced its climate change action plan for reducing its greenhouse gas emissions by 80 percent from 1990 levels by 2050 and explained how that plan will work with its recently adopted carbon market, which it plans to link with that of California and Quebec in 2018.
According to the Ministry of the Environment and Climate Change, the action plan helps define how market proceeds will be spent. “By law, proceeds must be invested in projects and programs that help reduce greenhouse gas pollution,” said the ministry.
Most of the action plan’s C$8.3 billion in planned spending on combatting climate change will come from the annual C$1.9 billion that the government expects to raise by auctioning greenhouse gas emissions credits.
Canada’s four most populous provinces—representing 86 percent of Canadians—have, or are introducing carbon pricing, either through a carbon tax or a cap-and-trade program aimed at emissions reductions.

Yellowstone National Park, Venice, Jordan’s Wadi Rum, and Easter Island’s Rapa Nui National Park are some of the 31 natural and cultural World Heritage sites in 29 countries that are threatened by climate change according to a new report released by UNESCO, the United Nations Environment Program and the Union of Concerned Scientists. Melting glaciers, rising seas, increasing wildfires and harsher droughts could severely diminish the value of protected sites, making them unsuitable for a World Heritage designation, the report says. Climate change could eventually cause some of the sites to lose their status.
Also at risk, according to the report, is local economic development in the areas near world heritage sites. Specifically, the tourism sector is vulnerable to loss and damage to assets and attractions as well as to increasing insurance costs and safety concerns.
“The fastest growing risk to World Heritage, and one of the most under-reported by the countries that are parties to the World Heritage convention, is from climate change,” said Adam Markham, deputy director of the Climate and Energy Program at the Union of Concerned Scientists. He pointed out that climate change brings not only direct impacts but “acts as a ‘risk multiplier,’” compounding local stresses such as urbanization, agricultural expansion and pollution.
In the Galapagos Islands, threats to wildlife from tourism, invasive species and illegal fishing are exacerbated by rising seas and warming and more acidic oceans. At Stonehenge, warmer winters will likely increase numbers of burrowing animals that could undermine archaeological deposits and destabilize stonework.
“Globally, we need to better understand, monitor and address climate change threats to World Heritage sites,” said Mechtild Rössler, director of UNESCO’s World Heritage Centre. “As the report’s findings underscore, achieving the Paris Agreement’s goal of limiting global temperature rise to a level well below 2 degrees Celsius is vitally important to protecting our World Heritage for current and future generations.”
Ocean Current Affecting Temperatures in Antarctica
A new study in the journal Nature Geoscience suggests that ocean currents are slowing the warming effects on Antarctica as Arctic ice melts on the other side of the world. Warm waters in Gulf Stream cool as they flow into the North Atlantic, then sink for centuries before surfacing off the coast of Antarctica.
“With rising carbon dioxide you would expect more warming at both poles, but we only see it at one of the poles, so something else must be going on,” said Kyle Armour, lead author and University of Washington assistant professor. “We show that it’s for really simple reasons, and the ocean currents are the hero here.”
Old, deep water that’s coming up to the surface all around Antarctica—water that hasn’t come into contact with the atmosphere or experienced climate change in hundreds of years—is behind the drastic differences in the continent’s water temperature.
Using drifting floats—known as the Argo array—and climate models, the study authors tracked heat. They found that nearly 68 percent of the heat taken up by the southernmost parts of the Southern Ocean was carried north.
A separate study in the journal Remote Sensing of the Environment also attributes ocean currents, in part, to increasing Antarctica temperatures and sea ice growth. It suggests that the Southern Ocean Circumpolar current prevents warmer water from reaching the continent and that icy winds help the formation of sea ice persist.
Record Renewable Investment by Developing Countries in 2015
For the first time, emerging economies spent more on renewable energy than developed economies, according to the Renewables Global Status report prepared by the Renewable Energy Policy Network for the 21st Century (REN21). In 2015, developing countries invested $156 billion in renewables—a 19 percent increase from the previous year.
“What is truly remarkable about these results is that they were achieved at a time when fossil fuel prices were at historic lows, and renewables remained at a significant disadvantage in terms of government subsidies,” said Christine Lins, REN21’s executive secretary.
By the end of 2015, countries around the world had installed a record annual total of 147 gigawatts of renewable generating capacity—enough to meet 23.7 percent of global electricity demand. China was the leader in renewables investment, followed by the United States, Japan, the United Kingdom and India.

A new study published in the journal Nature is drawing attention to the effect of warming water on the world’s largest ice mass, Totten Glacier in East Antarctica. Melting of the glacier, which has an ice catchment area bigger than California, could lift oceans at least two meters (6.56 feet). According to researchers who mapped the shape of the ice sheet as well as the thickness of rocks and sediments beneath it to examine the historical characteristic of erosion of Totten’s advances and retreats, unabated climate change could cause the glacier to enter an irreversible and rapid retreat within the next century.
“While traditional models haven’t suggested this glacier can collapse, more recent models have,” said study co-author Alan Aitken of the University of Western Australia. “We confirm that collapse has happened in the past, and is likely to happen again if we pass a tipping point, which would occur if we had between 3 and 6 degrees of warming above present.”
Aitken said that the Totten Glacier could ultimately account for nearly 15 percent of Antarctica’s total contribution to sea-level rise.
Satellite measurements from a previous study show that the glacier is thinning at a rate of about half a meter per year—a thinning that is most likely due to warm ocean water moving under and melting the glacier’s floating front. A retreat of another 100–150 kilometers (62–93 miles) may cause that front to sit on an unstable bed, triggering the Antarctic ice to shrink by 300 kilometers (186 miles).
“The evidence coming together is painting a picture of East Antarctica being much more vulnerable to a warming environment than we thought,” said study co-author Martin Siegert of Imperial College London. “This is something we should worry about.”
Index Suggests Increase, Acceleration of Carbon Dioxide Levels
The latest Annual Greenhouse Gas Index released by the National Oceanic and Atmospheric Administration (NOAA) shows that carbon dioxide levels in the atmosphere are not just rising but accelerating and that the level of methane, another potent greenhouse gas, rose sharply last year. The index, which compares global greenhouse gas emissions to pre-industrial revolution levels, suggests that warming capacity has increased 37 percent since 1990.
“We’re dialing up Earth’s thermostat in a way that will lock more heat into the ocean and atmosphere for thousands of years,” said Jim Butler, director of NOAA’s Global Monitoring Division.
According to the latest index, the global average carbon dioxide concentration for 2015 reached 399 parts per million (ppm), far above the 278 ppm just prior to the Industrial Revolution and a record increase of 3 ppm compared to the year previous.
Following on the heels of that news, NOAA and the National Aeronautics and Space Administration (NASA) reported that last month was the hottest April on record. According to the World Meteorological Organization, April marked the 12th consecutive month of global temperature records, the longest such streak since global record-taking began in 1880.
EPA Proposes Rise in Biofuel Targets
The U.S. Environmental Protection Agency (EPA) proposed an increase in the amount of corn-based ethanol and biofuels that must be blended into the nation’s fuel supply in 2017. The new targets call for 18.8 billion gallons of biofuels, up 4 percent from 2016 but far less than the 24 billion-gallon biofuel target that lawmakers established in a 2007 statute.
The reason for the lower-than-mandated target, EPA says, is lack of infrastructure to blend ethanol into gasoline as well as the cellulosic biofuel industry’s slow development and marketplace constraints, such as lower gasoline and diesel demand than Congress envisioned in 2007.
Nevertheless, acting assistant administrator for EPA’s Office of Air and Radiation Janet McCabe said that the Obama administration is “committed to keeping the [biofuels mandate] on track, spurring continued growth in biofuel production and use, and achieving the climate and energy independence benefits that Congress envisioned from this program.”
Under the renewable fuel standard (RFS), the proposed rule sets the 2017 renewable volume obligations (RVOs) for cellulosic biofuel at 312 million gallons and the advanced biofuel RVO at 4 billion, and it sets the 2018 RVO for biomass-based diesel at 2.1 billion gallons.
The proposed volumes would represent growth over historic levels. Between 2016 and 2017, total renewable fuel volumes are expected to increase by nearly 700 million gallons and advanced renewable fuels, which require 50 percent reductions in life-cycle carbon emission, by nearly 400 million gallons.
The proposed volumes are subject to public comment through July 11, and a public hearing is scheduled June 9. The EPA has until Nov. 30 to finalize the 2017 quotas.
Editor’s Note: Dec. 7–11 we will present a series of special issues of The Climate Post featuring updates on climate negotiations and commentary from our staff in Paris.
At the United Nations Climate Change Conference in Paris, world leaders on Monday suggested that stakes are too high to end negotiations on Dec. 11 without inking a climate deal that would limit global warming to two degrees Celsius over preindustrial levels—the U.N.-declared threshold for avoiding the most dangerous climate change impacts.
NPR reports that observers hope the deal will include three main items: agreement by countries to increase pledges in the future, a rigorous system of accountability to ensure nations keep those pledges, and support for poor countries to adopt low-carbon energy technologies.
A major sticking point for delegates of the nearly 200 countries meeting at the conference is the legal status of the treaty they hope to ink.
“Although the targets themselves may not have the force of treaties, the process, the procedures that ensure transparency and periodic reviews, that needs to be legally binding,” President Obama said in Paris. “…that’s going to be critical.”
Countries Pledge Financing for Clean Energy, Withdraw It for Coal
Another key negotiating point in Paris will be whether developing countries get enough financing to make the transition to clean energy worth it given the comparative cheapness of coal. In an announcement intended to give the U.N. climate talks momentum, the leaders of 19 nations, including the United States and many developing economies, on Monday pledged a doubling of clean energy spending to $20 billion in a deal with 28 corporate leaders (the so-called Breakthrough Energy Coalition spearheaded by Microsoft co-founder Bill Gates) who are putting up billions of their own (subscription).
According to a White House e-mail, the public component of the public-private agreement, known as Mission Innovation, is aimed at helping energy technologies “cross the investment ‘valley of death’” presented by their risk profiles and long return time horizons.
Brian Deese, White House climate adviser, said that Mission Innovation “should help to send a strong signal that the world is committed to helping to try to mobilize the resources necessary to ensure that countries around the world can deploy clean energy solutions in cost-effective ways.”
In an editorial for the Boston Globe, U.S. Energy Secretary Ernest Moniz wrote that Mission Innovation and the Breakthrough Energy Coalition are “synergistic initiatives that establish clean energy innovation as a foundation for environmental stewardship, prosperity, security and social responsibility. Strong American leadership in these initiatives has provided a tremendous global leveraging opportunity, and innovation has remained common ground in our political discourse.”
Three questions raised by the initiatives are whether a multinational research effort combining public and private investments could entail intellectual property problems, how much of the newly pledged money might represent formerly pledged funding, and whether the future funding will be approved in national budgets.
In the lead up to the Paris talks, some of the countries that just committed financial support for clean energy signed on to a deal to severely cut funding for some prospective coal projects. A promise by China to control its support for high-carbon projects overseas—part of its most recent climate agreement with the United States—allowed Japan and the United States to develop a proposal that last month became a less stringent agreement by members of the Organisation for Economic Co-operation and Development (OECD) to curb public financing for coal plants (subscription). Under the policy, which goes into effect in 2017 and will be up for revision in four years, OECD countries will continue to provide export credits for “ultra-supercritical” coal-fired power plants—those constructed to meet the most stringent environmental standards—but public financing for 85 percent of coal plants going forward would effectively be cut off. The agreement does allow support for less efficient plants with a capacity under 500 megawatts in the world’s poorest countries.
House Votes to Block Power Plant Rules
The House approved, largely along party lines, to block the Obama administration’s measures to reduce greenhouse gas emissions from power plants. The House voted 242–180 to repeal the Environmental Protection Agency’s Clean Power Plan, which would limit carbon emissions from existing power plants, and 235–188 to block EPA rules governing emissions from new power plants. The votes come just weeks after the Senate passed legislation blocking U.S. Environmental Protection Agency rules that apply to new and existing power plants.
The resolutions now go to President Obama, who last month announced plans to veto them, claiming that they undermine public health protections of the Clean Air Act and “stop critical U.S. efforts to reduce dangerous carbon pollution from power plants.”
The recent publication of the U.S. Environmental Protection Agency’s (EPA) Clean Power Plan in the Federal Register triggered the filing of lawsuits by dozens of states in the U.S. Court of Appeals for the District of Columbia Circuit, along with other challenges, including a petition from a U.S. Chamber of Commerce-led industry coalition for a rule review and an immediate stay of the regulation. By Monday, 26 states, 15 trade groups, several labor unions, and a host of individual utilities and companies were suing the administration over the Clean Power Plan. By Tuesday, members in both the House and the Senate introduced Congressional Review Act resolutions to stop them (subscription)—resolutions described by The National Journal as “a bid to undermine international climate talks.”
Clean Power Plan critics—among them attorney generals from West Virginia (Patrick Morrisey) and Texas (Ken Paxton), who are leading the states’ legal challenge—allege that the state-by-state targets aimed at cutting carbon dioxide emissions from power plants 32 percent from 2005 levels by 2030 represent a federal overreach and will hike utility rates and undercut grid reliability.
“The Clean Power Plan is one of the most far-reaching energy regulations in this nation’s history,” said Morrisey. “EPA claims to have sweeping power to enact such regulations based on a rarely used provision of the Clean Air Act, but such legal authority simply does not exist.” But the EPA and many environmental groups contend that the federal government does have the legal authority to curb power plant emissions, and The Huffington Post noted that in the past the U.S. Supreme Court has ruled in the EPA’s favor.
“The power plan is based on a sound legal and technical foundation,” said Acting Assistant Administrator for the EPA’s Office of Air and Radiation Janet McCabe. “We feel strongly that given our authorities and legal precedents under the Clean Air Act that our application of [Section] 111(d) here conforms with those authorities and that legal precedent.”
As part of its efforts to help states figure out how to implement the regulation, the EPA last week released a memorandum to regional EPA directors that lays out elements to be included in initial plan submittals to the EPA in September, should states desire to extend their deadline for final plan submittals to 2018.
Even while challenging the Clean Power Plan, some states are simultaneously thinking about developing compliance strategies, which could include creation of carbon-trading plans that allow big polluters to buy emissions credits from lesser emitters.
Also published in the Federal Register last week was the final rule regulating carbon dioxide for new, modified, and reconstructed power plants and the proposed federal implementation plan. That plan—to be imposed on states that fail to submit a compliance plan to the EPA—will be the subject of public hearings in November and a 90-day comment period ending January 21.
Draft Climate Deal Text Sent to Paris
On Friday diplomats endorsed the outlines of a proposed global climate deal to be negotiated starting Nov. 30 in Paris. The hope is to come to an agreement— by the summit’s conclusion on Dec.11—that limits warming to 2 degrees Celsius above pre-industrial levels to avoid the most significant effects of climate change. U.N. Climate Chief Christina Figueres said this week that based on some 150 plans submitted thus far, diplomats could only hope to limit warming to just below 3 degrees.
Even when talks start next month, countries that produce 92 percent of greenhouse gases in the world are expected to have submitted national plans. If fully implemented, they would hold temperature rise by the end of the century to 2.7 degrees Celsius.
“There’s nobody out there that wants a 3 degree world,” said Figueres. “Nobody. We are not giving up on a 2 degree world. In fact, we’re staying under 2 degrees. And what we’re doing is we are building a process that is going to get us there.”
But the goal will have to be met without a global carbon price, Figueres said, which could help create an incentive for power plants operators to switch to clean energy.
“[Many have said] we need a carbon price and [investment] would be so much easier with a carbon price, but life is much more complex than that,” she said. “…it’s not quite what we will have.”
There will be—and are—many pricing mechanisms in place around the globe. Many U.S. states are expected to develop trading-ready plans to meet the mandates laid out by the Clean Power Plan.
Report Finds New Highs in Store for Persian Gulf
“Our results expose a regional hotspot where climate change, in the absence of significant mitigation, is likely to severely impact human habitability in the future,” authors write.
It predicts that a 95-degree wet-bulb temperature—the indicator of humidity that matches the temperature of our skin when we sweat—is too hot for extended periods of time. And that temperature could be exceeded in summer months in certain parts of the region.
Most countries have now submitted emissions plans ahead of the Paris climate talks later this year, but success in forging a global treaty in Paris is far from guaranteed. Delegations from nearly 200 countries are meeting this week in Bonn, Germany, to pin down details of a draft agreement ahead of the U.N. talks. On the opening day, the dropping of language on financing of climate change and adaptation efforts from the draft text caused concern on the part of developing nations. After countries were invited to reinsert language, the text grew by more than a dozen pages (subscription).
Daniel Reifsnyder, one of the U.N. talks’ chairmen and a senior State Department official, said the Bonn meeting won’t resolve one of the biggest issues of disagreement for delegates—differentiation of developed countries and developing countries’ responsibilities. Progress might be made on other issues, he said, such as “whether there should be a precondition—like submitting a domestic climate plan to the U.N.—to join the agreement and to exercise decision-making rights.”
Looking for a strong outcome at the Paris talks are 81 U.S. companies. On Monday, the White House announced that 68 companies—ranging from banks to energy firms—had joined Alcoa, Apple, Bank of America, Berkshire Hathaway Energy, and nine other original signatories to the White House-sponsored American Business Act on Climate Pledge. Signatories to the pledge, announced this summer, call for the Paris meeting to advance climate action and have offered up individual promises to cut their greenhouse gases and limit waste.
“Delaying action on climate change will be costly in economic and human terms, while accelerating the transition to a low-carbon economy will produce multiple benefits with regard to sustainable economic growth, public health, resilience to natural disasters, and the health of the global environment,” the pledge says.
The White House also said on Monday that it expects a consortium of major investors to announce $1.2 billion in investment capital for companies and projects that can “produce impactful and profitable solutions to climate change.”
Study: Some Cities Already “Sunk” Due to Sea-Level Rise
Some 400 U.S. towns and cities with a collective population of more than 20 million are vulnerable to sea level rise—and some of them may be submerged regardless of efforts to address climate change, according to a study published in the Proceedings of the National Academy of Sciences that links carbon dioxide to sea level rise. A new map from Climate Central uses the study data to show how water will flow into U.S. cities under the best and worst climate change scenarios. The map pinpoints which U.S. cities may face “lock-in dates beyond which the cumulative effects of carbon emissions likely commit them to long-term sea-level rise that could submerge land under more than half of the city’s population.”
Lead study author Ben Strauss said that seas could rise 14–32 feet by 2100 in the absence of unchecked carbon emissions but that even with stringent emissions reduction action, it might already be too late for cities like New Orleans and Miami (subscription). Inundation could occur, he said, as soon as the next century, but it could take much longer.
The study finds that decisions made in this century will determine whether Jacksonville, Norfolk, Sacramento, and 11 other U.S. cities with populations greater than 100,000 will be locked in for inundation of at least half of their populated areas.
Strauss emphasized that many cities can be saved with swift action to reduce carbon emissions.
“The most interesting thing to me is there are a great deal of cities where our carbon choices make a huge difference,” he said. “For example, if you look at Philadelphia, under business as usual, land that accounts for more than 100,000 people could be submerged. But you divide that total by 10 with an extreme carbon cut. The very biggest difference of all is for New York City, where you can avoid submergence of land where one and a half million people live.”
September Global Average Temperature Keeps 2015 on Track for Record
Earth is on course to experience its warmest year on record, according to data and patterns studied by the National Aeronautics and Space Administration (NASA), the National Oceanic and Atmospheric Administration (NOAA), and the Japan Meteorological Agency (JMA). NASA put 2015’s record-breaking chances at 93 percent. NOAA put them at 97 percent.
The news comes as a JMA data set that tracks global average surface temperatures indicated a big jump in temperatures in September, compared to the 1981–2010 average. September 2015, the second warmest September on record, had a temperature anomaly of 0.50 degrees Celsius, far exceeding the typical margin by which global average temperature records—whether they’re months or years—are set.
Four of the five candidates mentioned climate change a dozen times as a major campaign issue during at the Democratic presidential debates this week. Candidates at the Republican debate were largely silent on the issue.
“This debate shows that climate has become a central issue, right up there with income inequality and broader economic concerns,” said Paul Bledsoe, a climate official under the Clinton administration. “It’s a stunning evolution, one that also shows Democrats see climate change has a profound GOP vulnerability in the general election.”
Vermont Sen. Bernie Sanders and former Maryland Gov. Martin O’Malley touted their own efforts to combat climate change. “I’m the only candidate, I believe, in either party to do this—to move America forward to a 100 percent clean electric grid by 2050,” said O’Malley.
Sanders brought up his push for legislation that puts a price on carbon, and he identified climate change as the main threat for the country—repeating Pope Francis’s message that it was a moral issue.
“The scientific community is telling us: if we do not address the global crisis of climate change, transform our energy system away from fossil fuels to sustainable energy, the planet that we’re going to be leaving our kids and our grandchildren may well not be inhabitable,” Sanders said.
Hillary Clinton, meanwhile, saw climate change as an economic opportunity.
“I’ve traveled across our country over the last months listening and learning,” Clinton said. “And I’ve put forward specific plans about how we’re going to create more good-paying jobs: by investing in infrastructure and clean energy, by making it possible once again to invest in science and research, and taking the opportunity posed by climate change to grow our economy.”
Group Calls for Tougher Action on Climate Change
Twenty countries most at risk of climate change due to arid, landlocked, mountainous, or low lying terrain have formed a new group to demand tougher efforts to curb climate change. The Vulnerable 20 (V20), which held its inaugural meeting in Lima, Peru, last week, is calling for significant mobilization of finance for climate action ahead of a climate agreement set to be negotiated in Paris later this year, and it will share and scale up its own members’ innovative approaches to such finance.
The action plan by the V20 countries—Afghanistan, Bangladesh, Barbados, Bhutan, Costa Rica, Ethiopia, Ghana, Kenya, Kiribati, Madagascar, Maldives, Nepal, Philippines, Rwanda, Saint Lucia, Tanzania, East Timor, Tuvalu, Vanuatu, and Vietnam—seeks to “strengthen economic and financial cooperation and action to address climate change risks and opportunities” as well as to promote a shift to a low-carbon global economy.
The V20 contributes only 2 percent of all global greenhouse gas emissions but asserts that since 2010 it has recorded more than 50,000 annual deaths and suffered an estimated annual decrease in GDP of 2.5 percent attributable to climate change.
“We established this group recognizing the power and potential of finance as an integral tool in solving [climate change],” Cesar Purisima, the Philippines’ finance minister and chair of the V20. “Unified in our vulnerability, the economic threats and difficulties arising from climate change, and heightened sense of urgency on the issue, we stand together on the front lines of a battle we most certainly cannot afford to lose.”
V20 expects to both raise and manage climate monies, and it will establish a public-private “climate risk pooling mechanism,” an insurance-like fund for recovery from extreme weather events and disasters.
Without an effective global response, said Purisima, the V20’s annual economic losses due to climate change would exceed $400 billion by 2030.
New York Set to Explore Linkage with Carbon Markets
Last Friday, New York Gov. Andrew Cuomo announced four major actions by his state to combat climate change and reduce greenhouse gas emissions. One is becoming a signatory to Under 2 MOU—a memorandum of understanding among states, provinces, and cities worldwide to help keep Earth’s average temperature increase to less than 2 degrees Celsius, as measured against pre-industrial levels. Another is engaging partners in the nine-state Regional Greenhouse Gas Initiative (RGGI) in exploring the possibility of linking their power sector-only cap-and-trade program with California and Quebec’s economy-wide carbon markets and with Ontario’s cap-and-trade program, which may join California, Washington, and Quebec in the Western Climate Initiative as soon as 2017.
“Connecting these markets would be more cost-effective and stable, thereby supporting clean energy and driving international carbon emission reductions,” a release stated. “New York State will also engage other states and provinces to build a broader carbon market and further drive an international discussion that encourages government action on carbon emissions.”
ClimateWire reported that carbon trading among states is considered a key mechanism to comply with the Clean Power Plan, which regulates greenhouse gas emissions from existing power plants, and acting EPA air chief Janet McCabe has said that interstate trading, for which RGGI is regarded as a model, could help states maintain an affordable and reliable power supply (subscription).
RGGI members are expected to meet through 2016 to discuss both the future of their program, currently slated to end in 2020, and the program’s use as a possible compliance mechanism for the Clean Power Plan.
On his visit to Washington last week, Chinese president Xi Jinping announced that his country, the world’s biggest carbon polluter, will launch a national cap-and-trade scheme in 2017. The move would make China the world’s biggest carbon market and could strengthen global efforts to put a price on carbon.
The planned emissions trading program will consolidate China’s seven existing regional carbon markets and cover industries not currently regulated for carbon in the United States: iron and steel, chemicals, building materials, and paper manufacturing.
China has yet to announce specifics of its cap-and-trade plan, which will face political and technical challenges. “The devil of course is in the details,” said Timmons Roberts, a professor of environmental studies at Brown University. “It really does matter what the actual cap is.” He added that limits leading to a pre-2030 emissions peak would be a huge move.
Frank Jotzo, the director of the Center for Climate Economics and Policy at the Australian National University in Canberra and a close tracker of developments in China said the national emissions trading scheme will have a major signaling effect. “The world’s second-largest economy puts in place a price on carbon emissions, and this will be noted the world over,” he said. “If successful, it can grow into playing a major role in facilitating China’s objectives for a cleaner energy and industrial system.”
Jinping’s announcement occasioned this ironic observation in The Atlantic in reference to Republicans’ rejection of a cap-and-trade proposal in Obama’s first term, which led to enactment of climate control policy through regulation of the electric power industry in the form of the Clean Power Plan: “China, the largest self-avowedly communist nation in the world, has created a market to reduce its carbon emissions. And the U.S., the anchor of global capitalism, will limit them through government command-and-control.”
China also made a substantial financial commitment to help poor countries fight climate change—$3.1 billion.
U.N. Sustainable Development Goals Adopted
The United Nations General Assembly agreed to 17 new sustainable development goals, which expand on the eight Millennium Development Goals. The new goals are broken down into 169 specific targets each country has committed to achieve over the next 15 years. They focus on everything from eradicating extreme poverty and climate change to providing energy access for all.
Goal 7 is to ensure access to affordable, reliable, sustainable and modern energy for all. Two targets to put the world on this path are to increase the share of renewable energy in the global energy mix and to double the rate of improvement of energy efficiency by 2030.
World Energy Council Secretary General Christoph Frei welcomed the agreement on the goals. “The adoption of energy among sustainable development goals is timely, critical, and historic,” he said. “Timely because we need to master the energy transition at a time of greatest uncertainty in the energy sector. Critical because we will not solve energy access or achieve energy efficiency objectives without moving the agenda from those who want to those who can. Historic because the development community for the first time recognizes the fundamental role energy is playing in the achievement of most of the other sustainable development goals.”
Goal 13 is to take urgent action to combat climate change and its impacts. A few targets to get there—integrate climate change measure into national policies, strategies and planning as well as advance the Green Climate Fund—requiring developed countries to follow through on commitments to provide $100 billion by 2020 to aid developing nations’ efforts to adapt and mitigate climate-related disasters.
With the adoption of the 17 goals, attention now turns to the U.N. climate negotiations in Paris—where member states hope to adopt a global climate agreement. In a CNN editorial, U.N. Secretary General Ban Ki-Moon, said all could take a lesson from Pope Francis’s message on climate change.
“Pope Francis, in his recent encyclical, clearly articulated that climate change is a moral issue, and one of the principal challenges facing humanity,” said Ban Ki-Moon, mentioning the Pope’s recent visit to the U.S. where he address the U.N. and Congress. “He rightly cited the solid scientific consensus showing significant warming of the climate system, with the most global warming in recent decades mainly a result of human activity.”
Shell Suspends Arctic Drilling
Royal Dutch Shell suspended its search for oil and gas off the coast of Alaska for the “foreseeable future,” saying that Arctic oil reserves were insufficient and that the regulatory environment was too unpredictable to continue.
“Shell continues to see important exploration potential in the basin, and the area is likely to ultimately be of strategic importance to Alaska and the U.S.,” said Marvin Odum, president of Shell USA. “However, this is a clearly disappointing exploration outcome for this part of the basin.”
Although the decision was celebrated by some environmental activists who had protested Shell’s decision to drill offshore, it should give people on both sides pause, Mike LeVine of Oceana told U.S. News and World Report.
“Meaningful action to address climate change is almost certainly going to mean we can’t keep looking for oil in remote and expensive places,” he said. “Rather than investing in programs like this, we need to figure out how to transition away from fossil fuels and toward sustainable energy.”
Alaska House of Representatives member Ben Nageak told the Associated Press that the state must act quickly to find another source to fill its 800-mile trans-Alaska oil pipeline.
“We stood on the cusp of another economic boom that could have propelled our young people and their children to better futures,” Nageak said. But “a draconian and poisoned federal government” shut it down.
In China, 11 cities will peak greenhouse gas emissions—some as early as 2020—to eliminate nearly 25 percent of China’s urban total carbon pollution. In the United States, pledges from 18 cities range from carbon neutrality to carbon reduction. Seattle plans to be carbon neutral by 2050. Houston commits to a 42 percent reduction by 2016 and to 80 percent by 2050 (based on a 2007 baseline). Los Angeles aims for reductions of 45 percent by 2025, 60 percent by 2030 and 80 percent by 2050 (based on a 1990 baseline).
In addition to these greenhouse gas targets, the declaration also conveys intentions to regularly report emissions and to establish climate plans to reduce them.
“The commitments that the Chinese and American cities are taking … are a very important component of our broader efforts to deepen climate cooperation and to show that … the two largest emitters in the world are taking seriously our obligation to meet the ambitious goals that we set out last year,” said Brian Deese, a senior adviser to President Obama. He noted that the declaration builds on a climate change deal reached in November by Obama and Chinese President Xi Jinping last year. That deal called for the United States to lower greenhouse gas emissions as much as 28 percent below 2005 levels by 2025. China agreed to peak emissions by 2030.
The pledges come a little more than two months before nations gather for international climate negotiations Nov. 30 to Dec. 11 in Paris—a meeting intended to produce a deal that would commit all nations to reducing greenhouse gas emissions. But the 62 climate commitments leading up to the COP—may not be enough to keep global warming to the 2-degree Celsius threshold recommended by the United Nations, said U.N. Executive Secretary Christiana Figueres. Her “guestimate” of the pledges, which cover approximately 70 percent of global emissions, is that they would equate to 3-degrees Celsius of warming, compared with pre-industrial levels.
Met Office Report Predicts Warmer Times to Come
The same week researchers released a study finding that the snowpack in California’s Sierra Nevada has shrunk to a 500-year low, the U.K. government agency that studies global weather patterns released a peer-reviewed report suggesting the world is moving into a warming trend.
Several global changes, the Met Office says, are occurring simultaneously to cause the change. One is El Nino—warm bands of ocean water in the central and east-central Pacific—which is expected to occur this year and to be particularly strong.
“We know natural patterns contribute to global temperature in any given year, but the very warm temperatures so far this year indicate the continued impact of increasing greenhouse gases,” said Stephen Belcher, head of the Met Office Hadley Centre. “With the potential that next year could be similarly warm, it’s clear that our climate continues to change.”
Southern Ocean’s Carbon-Storing Capacity Increases, but for How Long?
A new study in Science finds that the Southern Ocean carbon sink has been reinvigorated, helping limit climate change. Its uptake of greenhouse gases stalled in the 1980s but roughly doubled to 1.2 billion tonnes—equivalent to the European Union’s annual man-made greenhouse gas emissions—between 2002 and 2011.
“It’s good news, for the moment,” Nicolas Gruber, an author of the study at Swiss university ETH Zurich, told Reuters. But he said it was unclear how long the higher rate of absorption by the Southern Ocean, the strongest ocean region for mopping up carbon, would last. Moreover, increased carbon dioxide could be bad news for marine life because, once absorbed in water, some of it becomes carbonic acid, which disrupt shellfishes’ ability to grow their protective shells.
Gruber and his colleagues analyzed 2.6 million measurements of carbon dioxide (CO2) concentration in the surface waters of the Antarctic Ocean made by ships over three decades. They concluded that the ocean’s carbon uptake fluctuates strongly, rather than increasing monotonically in response to the growing atmospheric CO2 concentration. Wind and temperature changes appear to drive these shifts, which are linked to low-pressure systems in the Pacific and high pressure over the Atlantic section of the Southern Ocean.
Peter Landschützer, a postdoctoral researcher involved in the study, said existing models can’t predict how patterns will change in the future, “so it is very critical to continue measuring the surface ocean CO2 concentrations in the Southern Ocean.” Currently, long-term datasets are the only reliable means for determining the evolution of the ocean’s carbon-storing capacity.
