The U.S. Global Change Research Program (USGCRP) coordinates federal research on environmental changes and their implications for society. The program began as a presidential initiative in 1989 during the Reagan — Bush era and called for “a comprehensive and integrated United States research program that…
December 6, 2009 . Climate change could be 1 1/2 times worse than previously anticipated The long term warming will likely be about 50% greater than thought. A new study that looks at climate sensitivity three million years ago when CO2 was thought to be…
The Airborne Faction Discussion: This topic is controversial only in the minds of radical climate skeptics. Actually there is controversy, but it is totally different from what the radical climate skeptics (RCS) is saying. What RCS propaganda says is that because the airborne fraction is…
This is some serious news. The study revised work that was done 20 years ago that showed the lag between atmospheric CO2 concentrations and global temperature. The previous study showed that there was a five month lag between CO2 concentrations and temperature. This new study…
In an interview with the AFP Pachauri said that the emphasis for emissions reductions for 2050 needed to be place on 2020 because of the unanticipated acceleration of climate change. "Strong and urgent action is needed" said Pachauri in a meeting of the ministers of…
October 10, 2009 years A A paper in the journal Science last week, published by a UCLA scientist (Dr. Tripati), shows that CO2 is higher today than at any time in the last 15 million years. The study looked at fossilized foraminifera, those tiny sea…
Well it did not happen, at least not yet. The economic crisis has not affected CO2 concentrations in the atmosphere. They continue to rise at an even faster rate than just a few years ago. The graphic on the right is probably familiar to most….
Delayed for nearly a decade by the Bush Administration, as soon as Obama came into office the EPA went back to work. The Ruling states: “This finding confirms that greenhouse gas pollution is a serious problem now and for future generations… In both magnitude…
What James Hansen, the most important climate modeler in the world, has said about CO2 concentrations: that we need to reduce our CO2 levels to 350 ppm. How are we going to do that with CO2 reductions? With a CO2 tax? With cap and trade? …
Published today in the Proceedings of the National Academies of Science by Solomon et. al. The paper warns that we have already started to see accelerating impacts, and that even if we were to stop emitting all greenhouse gasses today, changes would continue for 1,000…
