July 16, 2010 — Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia, says a new report from the National Research Council. Because CO2 in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe.”

“April 22, 2010 — Unless man-made carbon dioxide emissions are substantially curbed, or atmospheric carbon dioxide is controlled by some other means, the oceans will continue to become more acidic, says the summary of a congressionally requested study by the National Research Council. The long-term consequences are unknown, but a federal program under development is a positive move toward understanding and responding to the problem.”
