Climate Change

800,000 Years and Counting

A recent slashdot article sums up recent carbon research:

We've known since 2004 that the past 440,000 years have shown atmospheric carbon dioxide levels varying between about 200 and 300 ppmv, the difference in extremes being the difference between advancing ice sheets and our current clime. In 2005 the data were analyzed back to 650,000 years and were found to be much the same — Al Gore was proud to be able to show that then-new analysis in his 2006 movie An Inconvenient Truth. Now all 800,000 years of the ice column have been analyzed, and the data show much the same pattern, according to the researcher: 'When carbon dioxide changed there was always an accompanying climate change. Over the last 200 years human activity has increased carbon dioxide to well outside the natural range' — to 380 ppmv.

Scientific American looks at Energy and Climate Change

The Scientific American recently had a series of articles related to energy and climate change. Unfortunately, most of these require a subscription to access online. You can purchase them or buy the hardcopy.   A Climate Repair Manual [ INTRODUCTION ]
Global warming is a reality. Innovation in energy technology and policy are sorely needed if we are to cope   An Efficient Solution [ ENERGY EFFICIENCY ]
Wasting less energy is the quickest, least expensive way to stem carbon emissions   High Hopes for Hydrogen [ FUEL CELLS AND MORE ]
Using hydrogen to fuel cars may eventually slash oil consumption and carbon emissions, but it will take some time   The Rise of Renewable Energy [ CLEAN POWER ]
Solar cells, wind turbines and biofuels are poised to become major energy sources. New policies could dramatically accelerate that evolution   What to Do about Coal [ CARBON CAPTURE AND STORAGE ]
Cheap, plentiful coal is expected to fuel power plants for the foreseeable future, but can we keep it from devastating the environment?   A Plan to Keep Carbon in Check [ STRATEGY ]
Getting a grip on greenhouse gases is daunting but doable. The technologies already exist. But there is no time to lose.   Plan B for Energy [ SPECULATIVE TECHNOLOGY ]
If efficiency improvements and incremental advances in today's technologies fail to halt global warming, could revolutionary new carbon-free energy sources save the day? Don't count on it--but don't count it out, either   Fueling Our Transportation Future [ AUTOMOTIVE ANSWERS ]
New technologies, lighter vehicles and alternative fuels can lower greenhouse gas releases from cars and trucks   The Nuclear Option [ ROLE FOR FISSION ]
A threefold expansion of nuclear power could contribute significantly to staving off climate change by avoiding one billion to two billion tons of carbon emissions annually
