Latest Climatologists Stories
By Deborah Zabarenko WASHINGTON (Reuters) - The last few decades were the warmest on Earth in the past 400 years, and may well have been warmer than any comparable period since the Middle Ages, U.S. scientists reported on Thursday.
The Earth is running a slight fever from greenhouse gases, after enjoying relatively stable temperatures for 2,000 years. The National Academy of Sciences said Thursday the data are "additional supporting evidence ... that human activities are responsible for much of the recent warming."
Many scientists are not so sure that the oncoming train of global warming can be avoided. Temperatures are going to rise for decades to come because the chief gas that causes global warming lingers in the atmosphere for about a century.
Ozone pollution in the Northern Hemisphere, churned out by factories and vehicles that burn fossil fuels, is a major factor in the dramatic warming of the Arctic zone, NASA climate scientists reported on Tuesday.
NEW YORK (Reuters) - NASA's top climate scientist said the Bush administration has tried to stop him from speaking out since he gave a lecture in December calling for prompt reductions in emissions of greenhouse gases, The New York Times said on Saturday.

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Scientists say it's not easy to tell if global warming caused hurricanes Katrina and Rita but on Monday they forecast more unpredictable weather as Earth gets hotter.
Colorado State University scientist Roger Pielke Sr. has resigned from a Bush administration science advisory team in a disagreement over research into the causes of global warming.
WASHINGTON (Reuters) - A dispute over whether global warming is really happening may have been caused by the placement of sensors on weather balloons when studies were done in the 1970s, researchers said on Thursday.
Warmer oceans, more moisture in the atmosphere, and other factors suggest that human-induced climate change will increase hurricane intensity and rainfall, according to climate expert Kevin Trenberth of the National Center for Atmospheric Research.
