First-Ever Direct Observation of Greenhouse Gas Increase

A new study in the journal Nature offers that for the first time scientists have directly observed an increase in one major greenhouse gas at Earth’s surface.

“We see, for the first time in the field, the amplification of the greenhouse effect because there’s more CO2 [carbon dioxide] in the atmosphere to absorb what the Earth emits in response to incoming solar radiation,” said lead author Daniel Feldman. “Numerous studies show rising atmospheric CO2 concentrations, but our study provides the critical link between those concentrations and the addition of energy to the system, or the greenhouse effect.”

Feldman and other researchers from the Lawrence Berkeley National Laboratory and the University of California, Berkeley, measured the amount of infrared heat radiation from the sun reaching Earth’s surface and the amount of heat radiation the Earth emits back. Examination of carbon dioxide concentrations from 2000 to 2010 in Alaska and Oklahoma showed the “fingerprint of carbon dioxide” trapping heat in action. Some of the heat from Earth was being blocked by carbon dioxide in the atmosphere—allowing the researchers to calculate that this effect amounted to two-tenths of a watt per square meter of surface warming per decade (22 parts per million between 2000 and 2010).

“The data say what the data say,” Feldman said. “They are very clear that the rising carbon dioxide is actually contributing to an increased greenhouse effect at those sites.”

Net Zero Emissions—The Business Case

A recently leaked European Union planning document states that “the world’s states should commit to a legally binding emissions cut of 60 percent by 2050, with five yearly reviews.” Still, many scientists and policy experts want this year’s Paris climate talks to aim for net zero emissions. In fact, the latest draft climate agreement, forged a few weeks ago in Geneva, does contain 15 versions of a net zero greenhouse gas (GHG) emissions goal.

Using information in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report, the 2014 United Nations Environment Programme’s Emissions Gap Report, and other scientific literature, a new briefing note from Climate Analytics details timeframes for that goal. For a 66 percent likelihood of avoiding 2 degrees of warming by century’s end, GHG emissions would have to be 40–70 percent below 2010 levels by 2050 and would need to reach zero some time between 2080 and 2100, but energy and industry emissions of CO2 would have to reach zero no later than 2075 and perhaps as soon as 2060.

At the outset of the Geneva talks, The B Team, a group of leaders from the business and nonprofit sectors founded by Sir Richard Branson, referenced the 66 percent chance in endorsing a net zero emissions goal: “The B Team view a 1-in-3 chance of failure as an unreasonable risk scenario carrying significant cost implications, strengthening the business case for achieving net-zero GHG emissions by 2050.”

“Momentum is already growing in finance, business and political circles for a net zero goal,” wrote Mary Robinson, the United Nations Secretary General’s special envoy on climate change, in the foreword to The Business Case for Adopting the Long-Term Goal for Net Zero Emissions, a report published by Track0.org.

EPA Airline Emissions Plan under Review

The U.S. Environmental Protection Agency (EPA) first proposed the idea of regulating emissions for the airline industry, which accounts for 2–3 percent of global greenhouse gas emissions, last year. Media report that the EPA has now sent the White House’s Office of Management and Budget its draft conclusion on whether carbon emitted from airplanes is cumulatively harmful to the environment and what the agency might do to restrict emissions.

NBC reports on how a decision to regulate airline emissions could lead to fuel-efficient planes.

Following the White House’s review of the document, the EPA could, according to Think Progress, make a proposal to the public as early as May with a final decision coming in 2016. The Daily Caller; however, reports the EPA has no timeline in mind.

“We don’t have a timeline for doing a rule,” said an EPA spokeswoman. “For any potential EPA domestic rulemaking to adopt equivalent international standards, EPA would have to propose and then finalize an affirmative endangerment and cause or contribute findings for aircraft greenhouse gas emissions.”

Negotiations Heat Up in Closing Stages of UN Climate Change Conference

Optimism at the outset of the 2014 United Nations Climate Change Conference twentieth Conference of the Parties in Lima, Peru, has given way to the hard work of reaching high-level resolution prior to the December 2015 UN meeting in Paris.

Among the challenges is disagreement about regular auditing of carbon emission pledges. The European Union insists on a formal review of all country pledges, whereas the United States recommends a voluntary approach to emissions cuts with the disclaimer of no backtracking in targets. “You could assign every country a particular reduction that on paper looks like a perfect result and then you can’t get agreement on it,” said Todd Stern, United States Special Envoy for Climate Change. “This is a way to get everyone in.”

Another challenge is differentiating the responsibilities of developed countries and those of developing countries. China, Brazil, India, and South Africa, which have coordinated their positions at the Lima talks, want to make sure the potential new agreement will allow poorer nations to meet their prevalent needs such as poverty eradication. “Poor people have aspirations,” said India’s Environment Minister Prakash Javadekar. “We must give them energy access.”

Host country Peru, along with other Latin American nations (Chile, Colombia, Costa Rica, Guatemala and Panama), is pushing for aggressive emission cuts by major economies as well as emerging economies such as China and Brazil. However, critics are quick to point out the country’s poor record in protecting rainforests, which play a critical role as carbon sinks.

Struggling through hammering rainfall from Typhoon Hagupit, the Philippines are asking for all nations, developing and developed, to cut use of fossil fuels.

“The thinking of the pivot is—we’re going to take on commitments and do our part,” said Tony La Viña, a Philippine climate change delegate. “The call has always been for developed countries to act. But the thinking is simple. If we’re going to get hit every year again and again, how can we call on developed countries to reduce their emissions, but not reduce our own?”

A new UN report showing climate adaptation costs for developing countries could be two to three times higher than current global estimates makes the 2050 zero-carbon goal another contentious issue. Meeting this goal would significantly affect oil and gas production as well as coal extraction methods. “With a concept like zero emissions and ‘let’s knock fossil fuels out of the picture’, without clear technology diffusion and international cooperation program, you are really not helping the process,” said chief Saudi Arabian negotiator Khalid AbuLeif.

Emissions Reduction Pledges Underscore Importance of Social Cost of Carbon Estimates

The Climate Action Tracker report released by a group of independent scientists notes that recent pledges by the United States, China and the European Union to limit greenhouse gas emissions will, in fact, slow the rate of global warming this century, though not enough to limit warming to 2 degrees Celsius (3.6 Fahrenheit).

Draft text of the 2015 global climate change agreement being negotiated in Lima includes a May 3, 2015, deadline for nationally determined contributions—promises from individual countries for internal action on climate change. Figuring into these commitments are estimates of the social cost of carbon, or the per-metric-ton dollar value of reducing climate change damages—a metric that the United States uses in regulatory analysis and that it and other developed countries could use to leverage greater emissions reductions commitments from developing countries.

Several economy and environmental policy experts are recommending that the government change the way (subscription) it establishes this cost. In an article in Science, former U.S. Department of the Treasury Deputy Assistant Secretary for Environment and Energy and Nicholas Institute faculty fellow William Pizer and his coauthors recommend that the United States adopt a standardized process to regularly evaluate the cost and that the process undergo a public comment period and a review by the National Academy of Sciences.

Commenting on the need for a consistently used and rigorously maintained estimate of climate damages, Pizer said, “It’s important that we draw on the expertise of all government agencies, as well as independent experts in the field. This level of high-quality collaboration and peer review would decrease the likelihood of political factors interfering with the process, and ensure we have the most robust Social Cost of Carbon.”

2014—Hottest Year on Record?

A report issued by The United Nation’s World Meteorological Association says that 2014 is expected to be the hottest year on record, with global temperatures 1.03 degrees Fahrenheit above the 1961–1990 average.

“What we saw in 2014 is consistent with what we expect from a changing climate,” said Michel Jarraud, World Meteorological Organization Secretary-General. “Record-breaking heat combined with torrential rainfall and floods destroyed livelihoods and ruined lives.”

A report by National Oceanic and Atmospheric Administration that finds that the historic California drought is due to natural weather patterns, as opposed to hot temperatures across the state, raised the ire of some climate scientists, who said the report did not take into account how record warmth worsened the drought.

As Eurozone Crisis Deepens, Fight to Save Emissions Trading Scheme Begins

Editor’s Note: The Climate Post will not be circulated next Thursday in observance of the holiday. Look for it again on January 5.

Prices in Europe’s carbon emissions trading scheme have collapsed this year, in part because there were too many allowances in the system starting off, threatening the future of the whole market.

“Without intervention … Europe’s climate policy is over,” one analyst said. Some of Europe’s biggest energy and manufacturing firms also wrote a letter to the European Commission that called for Europe to take “decisive action now” to raise the price of carbon and fix the scheme.

The European Parliament’s environment committee voted in favor of temporarily cutting the number of emissions permits to be issued.

This year, the price of permits has fallen about 50 percent. Emissions allowances are now about 6 euros per ton—a four-year low, and about half what they were when the market began. Denmark, which will take over the presidency of the European Union in 2012, said the current carbon prices are “not sustainable” and vowed to help fix the problem.

Part of the problem is that Europe’s economic crisis is escalating, risking a slump like in the 1930s to which no country will be immune, said Christine Lagarde, managing director of the International Monetary Fund, in a speech at the U.S. State Department. Also, a new energy efficiency effort could also cut the number of permits needed, another reason to issue less in the future.

Paving the Way for De-carbonized Energy

The European Commission presented its long-awaited “Energy Roadmap 2050,” aiming to point the way to meet the European Union (EU) goal of cutting emissions at least 80 percent below 1990 levels by 2050.

The report considered various ways of reaching these targets, and concluded that relying heavily on renewables would be no more expensive than boosting nuclear, or fossil fuels along with carbon capture and storage.

A de-carbonized energy system could be cheaper than “business-as-usual,” although de-carbonization would require large up-front spending. The report also said natural gas will be a “critical” fuel during the transition.

The EU soon needs to set renewable energy targets for 2030, said EU Energy Commissioner Günther Oettinger.

Pollution Crackdowns

The European Union moved earlier this year to expand its emissions trading scheme to include flights in and out of Europe, and now the European Court of Justice has backed that law despite protests from the U.S. and others. The new decision, which goes into effect Jan. 1, may trigger a trade war.

Meanwhile, the U.S. Environmental Protection agency unveiled its first limits on emissions of mercury and several other toxic pollutants from power plants. The limits were 20 years in the making, and cover a variety of toxic compounds including arsenic, nickel, selenium, and cyanide.

The new standard gives companies three options: install systems to scrub their emissions, switch to natural gas, or shut down their plants. Some of the nation’s oldest—and generally dirtiest—coal-fired power plants may be forced to shut down, which could also benefit the climate.

Climategate Investigation Widened

The U.S. Department of Justice is apparently working with law enforcement officials in Britain to investigate who leaked climate researchers’ e-mails.

In the U.K., police raided the home of one climate skeptic blogger and confiscated two of his computers.

Flipping the Switch on Incandescents

A ban on the sale of incandescent light bulbs of 100 watts or more in the U.S. is supposed to go into effect Jan. 1, but an emergency spending agreement in Congress removed funds from enforcement of the ban, at least until October 2012. Experts say the lack of enforcement will likely have little effect, since light bulb manufacturers have already retooled and moved on.
