Panel Supports a Controversial Report on Global Warming





By ANDREW C. REVKIN, NY Times


An influential and controversial paper asserting that recent warming in the Northern Hemisphere was probably unrivaled for 1,000 years was endorsed Thursday, with a few reservations, by a panel convened by the nation's pre-eminent scientific body.



More broadly, the panel examined other recent research comparing the pronounced warming trend over the last several decades with temperature shifts over the last 2,000 years. It expressed high confidence that warming over the last 25 years exceeded any peaks since 1600. And in a news conference here on Thursday, three panelists said the current warming was probably, but not certainly, beyond any peaks since the year 900

Climate Confusion: Who Wins?

by Michael O'Brien Climate change is the biggest challenge we face as a humans. Any serious student who analyses the information recognizes that the overwhelming consensus from scientists is that we have a very small period of time in which our efforts will have a positive impact for our planet and our children's future. For the past 10 years or so, there has been rigorous debate both by the scientific community and in the press about climate change. The debate is over, the issues have been discussed and now is the time for us to take responsibility for our future. It is fascinating to watch the media feel the need to present the “other side” of this issue when there is discourse about climate change. My guess is that they feel vulnerable from the vocal skeptics or right wing talk show hosts so they include a dwindling number of scientists or spokespeople who argue against human causation.
