Study: Climate change may dry up important U.S. reservoirs like Lake Powell and Lake Mead

by

As climate change makes the regions of the West, Southwest, and Great Plains warmer and drier, water demand will continue to increase, and the combined effect will place an ever greater burden on the country’s fresh water supplies — possibly completely draining important reservoirs in those areas, under some scenarios. That’s according to a new study authored by researchers with Colorado State University, Princeton and the U.S. Forest Service, and flagged yesterday by Summit County Citizens Voice.

What kind of economy says OK to tar sands oil?

On Sunday, February 17, I marched in the largest climate change protest in U.S. history. About 35,000 people gathered on the Washington Monument grounds for a rally and then marched past the White House, calling on President Obama to deny permission for the construction of the Keystone XL pipeline that would transport oil from Canada’s tar sands through the heart of the U.S. to the Gulf Coast.

Hot carbon

Carbon is hot. This was the main message of a conference on climate change and agriculture that I attended last week in Davis, California. Everyone was talking about carbon, either as carbon dioxide in the atmosphere or soil carbon below our feet. Farmers, scientists, policy-wonks, regulators, graduate students, activists and many others all had something to say about carbon.

Is Bill McKibben’s math finally adding up?

by

You can’t build a movement without numbers. If anyone understands that, it’s 350.org co-founder Bill McKibben. Standing in front of an estimated crowd of 50,000 people gathered for the Forward on Climate rally yesterday on the National Mall in Washington, D.C. he said, “All I ever wanted to see was a movement of people to stop climate change, and now I’ve seen it.”

Individual matters

by

While environmental advocates urge individuals to reduce their carbon footprint by taking small, simple actions, others argue that individual actions are irrelevant. Do such actions have meaningful impact on the global systems that drive severe weather? Or is policy—corporate and government—the only thing that will make a real difference?

Economic growth, population growth and climate change

Recent work cited in our report shows that the remaining global fossil fuel resources (mainly coal) would produce an enormous 9-13 trillion tonnes of greenhouse gas emissions. If all of it were burnt without capturing the carbon it would be enough to raise the average global temperature some 18 degree C, may be more. This 9-13 trillion tonnes is large compared with the 0.5 trillion tonnes already produced since the start of the Industrial Revolution. Nearly half of this 0.5 trillion tonnes remains in the atmosphere causing serious problems resulting from a warming of only 0.6 degree C. A recent report by independent consultants shows that there are planned mega fossil fuel projects which would add nearly 2 trillion tonnes of carbon by 2020 . Discharging all of this to the atmosphere would set the world on a path to warming 5 -6 degree C, already the stuff of nightmares. Discharging the additional 7-10 trillion tonnes would be an act of insanity.

Sliding down the slippery slope: A truth too big for Obama

by

Now, the good news is, we can make meaningful progress on this issue [climate change] while driving strong economic growth.” With that sentence from his State of the Union address, President Obama capitulated to paltry cynicism. Alas, he will not be the president who finally comes clean on the trade-off between economic growth and environmental protection. Obama is now committed to win-win, green-growth rhetoric.
