CO2 levels hit new record in 2006

The World Meteorological Organization (WMO), in its new 2006 Greenhouse Gas Bulletin, reports:

In 2006, globally averaged concentrations of carbon dioxide (CO2) in the atmosphere reached their highest levels ever recorded ... 381.2 parts per million (ppm), up 0.53 per cent from 379.2 ppm in 2005.

Note this is a one-year rise of 2.0 ppm, continuing the accelerated trend of the past decade, which is due to increases in global economic activity and carbon intensity, together with decreased efficiency of natural sinks, like the ocean.

Must-see ice-sheet TV

Do you want the latest data -- some not yet published -- and the best post-IPCC scientific predictions on the stunning collapse of Arctic ice and unexpected shrinking of the Greenland (and Antarctic) ice sheets? Then you should definitely watch this C-SPAN video of yesterday's American Meteorological Society seminar (see note on link below).

The seminar is by three of the world's top cryosphere experts: Dr. Mark Serreze (NOAA), Scott Luthcke (NASA), and Dr. Konrad Steffen (CIRES) -- full bios and program summary available here. I will post their presentations when AMS puts them online (which will be here).

I have spent a great deal of time studying the ice and sea-level-rise issue (see links below) and still found the presentations informative and startling. It is very safe to say the Arctic Sea will be essentially ice-free by 2030, and I'd personally bet on 2020 -- any takers?

A possible compromise in energy legislation negotiations

The Detroit Free Press reports:

Congressional negotiators are close to agreement on an increase in fuel economy standards to 35 miles per gallon by 2020, with some caveats to satisfy U.S. automakers.

What caveats?

The compromise would preserve the distinction between cars and trucks, something Detroit automakers have fought for, while giving federal regulators strict limits on how to put the increases into place. It also would include a provision backed by the UAW aimed at keeping small-car production in the United States.

Still, much better than no deal at all.

The next president needs to move with speed and clear vision on mitigating climate change

This post is by ClimateProgress guest blogger Bill Becker, Executive Director of the Presidential Climate Action Project.

As I mentioned in a previous post, many of my colleagues in climate-action circles are delighted at the detailed commitments the presidential candidates in the Democratic field are making around global warming. It seems ungrateful to ask them for more. But ask we must.

We need to know what they'll do to act quickly. And we need to hear their unifying vision for the post-carbon world.

On speed: We've all read Jim Hansen's warning that the international community must take significant action within a decade if we wish to avoid the most dangerous consequences of global warming.

Now the head of the Intergovernmental Panel on Climate Change has moved up the deadline. In announcing the IPCC's final report on Nov. 16, Rajendra Pachuari warned, "If there's no action before 2012, that's too late. What we do in the next two to three years will determine our future. This is the defining moment."
