As Population Tops 7 Billion, Time to Revisit Climate Approaches

The Nicholas Institute for Environmental Policy Solutions at Duke University

The world population reached seven billion people around October 31, according to United Nations estimates. The actual date is a bit fuzzy, but the milestone has nonetheless had great symbolic power, triggering a stream of articles on population issues.

Nicholas Kristof, in the New York Times, argued family planning is the solution to many of the world’s ills, from climate change to poverty to civil wars—but this work has been starved of U.S. funds in recent years.

Population expert William Ryerson said the environmental movement initially focused on population, and then it became taboo—and since we haven’t pursued birth control more vigorously, we’ve failed to take some of the easiest steps to deal with climate change and resource scarcity.

The United Nations Development Programme’s annual report on the quality of life worldwide warned that unless we deal with environmental challenges including climate change, the progress developing countries have made could slow or reverse.

Paul Ehrlich of Stanford University, famous for his book The Population Bomb, said people will have trouble feeding themselves as climate change worsens. But it’s a catch-22, he said, because we need to expand agriculture, but as it’s practiced today it is also one of the biggest emitters of greenhouse gases.

A new report from the Nicholas Institute for Environmental Policy Solutions says there are a number of strategies for reducing emissions from agriculture using on-farm management practices such as no-till farming and by utilizing fertilizer more strategically.

Extreme Weather

Already climate change is taking its toll, most likely responsible for an increase in extreme weather, according to a leaked draft of an upcoming report from the Intergovernmental Panel on Climate Change. The report said there is a two-in-three chance that global warming has made disasters more common—and that scientists are 99 percent certain there will be more extreme heat spells and fewer cold spells.

This year the U.S. has already broken its record—set last year—for the most major disasters, reaching 89 by the end of October.

Meanwhile, there’s a push to make climate science more practical, with a shift from scenarios to short-term forecasts, reported The Daily Climate. Also, an initiative by the World Meteorological Organization is working to create “downscaled” results of climate models to provide village-by-village projections of climate change impacts across Africa.

Executive Decision on Pipeline

A proposed pipeline that would carry tar sands from Canada to Texas encountered protests in front of the White House, and now Nebraska lawmakers have introduced a bill to give state officials authority over pipeline routes.

In response, President Barack Obama said Nebraskans shouldn’t have to risk their water supplies in exchange for jobs the pipeline would create.

To help settle matters, Obama will make the decision himself about the pipeline, rather than delegating the job to the State Department, which has been reviewing the case for three years, but which was recently accused of having too close of ties with the company that wants to build the pipeline.

Oil Addiction Threatens Security

The U.S. transportation sector’s dependence on oil is the Achilles heel of U.S. national security, argued a new report from CNA, a military think tank. It also said the Department of Defense, America’s single largest user of oil, should drastically cut its oil use and cut dependence on imported oil by 30 percent in the next decade.

California Adopts Cap-and-Trade System, Serves as Greenhouse Guinea Pig

After a unanimous vote by the California Air Resources Board, the state adopted the most comprehensive cap-and-trade system in the country, a key part of a 2006 global warming law that had yet to be implemented. The system will cover 85 percent of greenhouse gas emissions in the state, and allows businesses to counterbalance up to 8 percent of their emissions by buying offset credits.

The state is making itself a guinea pig for climate legislation and hopes to inspire other states to follow suit—a precedent the state has set with other environmental legislation.

At first, most of the emissions credits will be given out free, but it’s expected by 2016 to be a $10 billion market.

Slow Growth

After the economic crash of 2008, the growth of clean energy slowed—and the outlook for the rest of the decade is single-digit growth, according to analyses by IHS Emerging Energy Research and others. A major factor has been that cash-strapped governments have cut back on subsidies that helped drive the growth in renewables.

The U.K. reshuffled its renewable subsidies, taking away from onshore wind and hydro power, and giving more to tidal and biomass power plants. Scotland—which sets its subsidies separately from the rest of the U.K., and which boasts some of the world’s best wind and tidal resources—also made subsidy support adjustments.

Industry experts fear the U.K. may soon slash solar subsidies by half—after already cutting them earlier this year—so they are encouraging people to install solar systems now.

But the World Wildlife Fund argues that high growth of renewables is still possible, and the U.K. could get nearly all of its energy from renewables by 2030.

In the U.S., solar industry jobs grew about 7 percent in the past year—much faster than job growth in the whole economy, but only about a quarter of the rate that the industry had expected, according to the Solar Foundation’s newly released National Jobs Census.

High-Tech Efficiency

In Europe, “business as usual will not be an option for most energy utilities,” according to McKinsey analysts who argued that energy demand is reaching a peak, and existing technologies could drastically cut consumption. In response, utilities should look to other services to keep their revenue up, such as selling solar panels, insulation, or central control units that track and manage a building’s electricity consumption.

One company is already trying to make such products cool. Nest Labs, a well funded start up founded by former Apple employees, have created a thermostat that studies your habits to help adjust the temperature to save energy.

Climate Change Conundrum

Climate change could exceed dangerous levels in some parts of the world during the lifetime of many people alive today, according to research papers published in the journal Nature.

University of Washington Professor of Philosophy Stephen Gardiner argued in Yale Environment 360 that humanity’s institutions aren’t up to the ethical challenge presented by environmental change. As these problems get worse, he argues, we might see apush for technological fixes such as geoengineering.

Some scientists are looking into such methods, and a U.K. group had planned a test flight of a balloon tethered to a hose—the kind that could shoot reflective aerosols into the atmosphere, scatter sunlight and potentially cool the planet. But that group postponed its test until spring to allow “more engagement with stakeholders”—which New Scientist argued is crucial.

Most of the public is not against such research on “solar radiation management” according to a new survey. But critics say the survey may be some biased toward geoengineering research.

Skeptic Changes Mind

A study led by a self-described climate change skeptic—physicist Richard Muller of the University of California, Berkeley—released results from a re-analysis of temperature records. The “biggest surprise,” Muller said, was how closely his study matched earlier assessments, such as those by NASA and the U.K.’s Hadley Centre. Muller’s study had been hailed by climate change skeptics since it took seriously many of their criticisms.

But in a Wall Street Journal op-ed, Muller said “global warming is real,” and argued no one should be a skeptic about this warming any longer.
