The clear message to emerge from the 3-day climate congress that wrapped up yesterday here in Copenhagen is that the prognosis on global warming is worse than anticipated by the IPCC in 2007. I reported the full story over on Nature News yesterday (no* subscription required). Here’s an excerpt:

The latest results made for bleak listening at times. Scientists cautioned that some of the impacts of global warming, such as sea level rise and loss of summer sea ice in the Arctic, are happening much sooner and more severely than scientists had estimated just two years ago. “What we are seeing now is that some aspects are worse than expected,” says Stefan Rahmstorf, head of Earth System Analysis at the Potsdam Institute for Climate Impact Research in Germany and a plenary speaker at the congress.

What is also clear from my news story is the growing sense of frustration that the urgency of climate change is failing to permeate. While I imagine the climate community has felt that way for some time, it was palpable at a different level this week, I felt. For one, there seemed to be a lot of finger pointing – at the media for poor reporting, at policy makers and the public for failing to understand, and at scientists for failing to make the implications of their work more policy prescriptive.

I can’t help feeling that’s not going to bring us much closer to reducing greenhouse gas emissions. At the final plenary session of the congress, Danish PM Prime Minister Anders Fogh Rasmussen said that scientists who want a significantly more ambitious global carbon cut target of 80 percent by 2050 must not move the goal posts.

If this sense of frustration can be channelled into very clear communication on what needs to be done and when we need to start, could it increase the chances of an effective deal being reached in Copenhagen?
