Upcoming AMS statement on climate change

The American Meteorological Society, the professional organization for many atmosphere and ocean scientists, is preparing a statement about climate change that presumably will be released at the annual meeting in January (?).

The current draft is a reasoned summary of the scientific evidence, and how that evidence should be interpreted and used. Since the organization is US-based, the climate change impacts of the paper tend to focus on the US (Alaskan permafrost, western water concerns). I'd like to see more mention of the sensitivity of the planet's ecosystems to climate variability and change, and examples of ecological impacts of past and projected future climate change (species migration, coral reefs, etc.). But that is less the mandate of AMS than other scientific organizations.

For a very direct summary of the evidence for human influence on the climate, I suggest reading the amicus brief (jump down to page 16 of the pdf) filed by 15 top scientists for the Supreme Court case. Thanks to Realclimate for the link.

The moment when the unusually powerful hurricane ‘Katrina’ hit New Orleans in the summer of 2005, people insisted on being informed and on understanding the phenomenon. Let’s assume that winter temperatures turn suddenly to Ice Age conditions (not experienced for more than one hundred years), but no one talks about this because there is a war going on. That was the case during the winter of 1939/40, when, in several locations in Northern Europe, average temperatures were more degrees lower than during the previous century, and the WWII war machinery cooled down the earth for four decades.

If this investigation succeeds in proving that two major wars changed the course of the climate twice in the last century, it will also prove that shipping, fishing, off-shore drilling, and other ocean uses had constantly contributed to the global warming since the start of industrialization, more than 150 years ago. A new chapter on the climate change issue could be now opened, giving more attention to oceanic phenomena under the influence of the potential of the “1982 United Nations Convention on the Law of the Sea” . All research would lead to a better understanding and protection of the stability of our short-term weather and long-term global climate.

I hope the report will focus on all the aspects and that it will solve something.
