Latest Climatologists Stories

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. Even skeptics agree that global warming is under way and that human activity is at least in part responsible. Climate experts also agree that this warming is likely to make the weather more extreme -- colder in some places, hotter in others, with...

DENVER (AP) -- 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. Pielke, who is also the state climatologist, said the Climate Change Science Program had minimized evidence that factors other than greenhouse gases can contribute to global warming. Pielke also said other members of the team went behind his back to rewrite a final chapter of its report. Pielke said...

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. Very few scientists now dispute that the Earth's temperature is rising, and that this is caused by human activity, including burning fossil fuels such as coal and oil. But there have been some discrepancies that have troubled experts. For instance, some measurements show...

BOULDER - 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. His paper, "Uncertainty in Hurricanes and Global Warming," appears in the Perspectives section of the June 17 issue of Science. "Trends in human-influenced environmental changes are now evident in hurricane regions,"...

One of Britain's leading climate change experts has thrown his weight behind the claim that global warming is being caused by human activity in a report published today by the Institute of Physics. The report by Professor Alan Thorpe, who takes up his post as chief of the Natural Environmental Research Council next month, aims to tackle sceptics who doubt the models scientists use to predict future climate change. Professor Thorpe outlines the scientific basis for climate change and explains...

NASA -- Last year was the fourth warmest year on average for our planet since the late 1800s, according to NASA scientists. To determine if the Earth is warming or cooling, scientists look at average temperatures. To get an "average" temperature, scientists take the warmest and the coolest temperatures in a day, and calculate the temperature that is exactly in the middle of those high and low values. This provides an average temperature for a day. These average temperatures are then...
