Climate News: Geo-engineering, Soot and Deforestation

Guest blogger Lisa Moore, Ph.D., is a scientist in the Climate and Air Program.

There’s always something new in climate change research. This week, scientists described the risks of geo-engineering, proposed an efficient way to reduce Arctic climate change, and discussed options for decreasing deforestation in developing countries.

With G8 Climate Agreement, Congress Must Act

Today’s guest blogger, Annie Petsonk, is International Counsel at Environmental Defense.

The Group of Eight (G8) is an international forum of eight industrialized countries representing the lion’s share of the world’s economy. High on this year’s agenda is global warming, with European countries calling for a mandatory 50 percent cut in global greenhouse gas emissions by 2050.

Recognizing that America must take the lead, the U.S. Climate Action Partnership (USCAP) has gone even further. This group of 27 leading U.S. companies and environmental groups has urged Congress to enact legislation [PDF] mandating that the U.S. cut emissions by 60 to 80 percent by 2050.

Today the G8 Summit reached an agreement.

Why does the "safety valve" matter to farmers?

Today’s post is from Sara Hessenflow Harper, a policy analyst for our national climate campaign. She does extensive outreach to the agricultural community.

Yesterday, Mark MacLeod wrote about the “safety valve” and its flaws. I wanted to add to the discussion a more specific look at its implications for rural America. In addition to the problems Mark noted, the “safety valve” would also cut farmers out of the carbon market. Here’s how.

What is the "safety valve"?

Today’s post is by Mark MacLeod, director of special projects for the national climate campaign at Environmental Defense.

Some people have proposed a “safety valve” to control the costs of a cap-and-trade policy to fight global warming. This post explains what a safety valve is, and why it provides only an illusion of cost management.

How does cap and trade work?

This post is by Mark MacLeod, director of special projects for the national climate campaign at Environmental Defense.

Cap-and-trade is the structure of most of the global warming bills being considered by Congress.

The “cap” is the cornerstone of the policy. It is an absolute, nationwide limit on global warming pollution. Congress would most likely establish a cap measured as billions of tons of carbon dioxide (or equivalent) released into the atmosphere each year. Over time, the cap would be lowered to cut emissions enough to avoid the worst consequences of global warming. (See our earlier series for more on how much we need to cut.)

The “trade” part is a market that creates powerful incentives for companies to reduce pollution, and provides flexibility in how companies can meet the limits.

Here’s how it works:
