Global environmental challenges
As if 2007 never happened?
At issue is the decision by American Electric Power to put its plans for carbon capture and storage on hold, due to the weak economy and the lack of a U.S. plan to limit emissions of climate-warming carbon dioxide. Read the Reuters story about it here.
Carbon capture and storage, or CCS for short, has been promoted as a way to make electricity from domestic coal without unduly raising the level of carbon in the atmosphere. Instead of sending the carbon dioxide that results from burning coal up a smokestack and into the air, the plan was to bury it underground. But that costs money and requires regulatory guarantees, and neither are imminent in the United States. Legislation to curb greenhouse gas emissions bogged down on Capitol Hill a year ago and has not been re-introduced.
Sarah Forbes of World Resources Institute called AEP’s decision “a surprise, but not a shock.”
Compare that to what happened in 2007. Senators Barbara Boxer, John Warner and Joe Lieberman joined forces that year to focus attention on climate change and were able to shepherd a carbon-limiting bill to the Senate floor the next year, the farthest any such measure has gotten in the United States. Al Gore, the former vice president and perennial climate campaigner, shared the 2007 Nobel Peace Prize with the United Nations’ Intergovermental Panel on Climate Change for bringing climate change to public attention.
On Groundhog Day of that year (why did they pick February 2?) the IPCC released its Fourth Assessment report on what was likely to happen in a warming world. The report forecast more severe weather, worse heat waves, dramatic droughts, wildfires and floods, rising seas and melting glaciers. It also famously said, with 90 percent certainty, that climate change was under way and that human activities contribute to it.
At about the same time as the report’s release, some of the biggest U.S. corporations — including some of its biggest carbon emitters — banded together into an organization called the U.S. Climate Action Partnership. The new group called on the U.S. government to “quickly enact strong national legislation to require significant reductions of greenhouse gas emissions.” Back then, that seemed a realistic possibility.
Also that year, the U.S. Supreme Court ruled that greenhouse gases could be regulated as pollution under the Clean Air Act.
Things have gotten a bit more complicated since then, with the economic downturn siphoning off attention from climate change issues that seemed paramount just a few years ago. Most of the U.S. climate regulations that seemed within reach in 2007 have yet to become law. A series of hacked emails of climate scientists at the University of East Anglia were used by those skeptical about human-generated climate change to cast doubt on scientific findings.
The Environmental Protection Agency started rolling out its rules to limit greenhouse gas emissions at the beginning of this year, but is likely to delay rules that would cut these emissions from power plants. There’s a lot of push-back from Republicans and many in the U.S. energy industry.
But the planet appears to be continuing to warm up. The U.S. National Oceanic and Atmospheric Administration’s statistics for the first half of 2011 show that last month was the seventh-warmest June since record-keeping began in 1880. Arctic sea ice extent was the second-smallest on record for June. Combined land and ocean surface average temperatures for June were 1.04 degrees F (0.58 degrees C) above the 20th century average, NOAA said.
