Al Gore showing pictures of the Hurricane Katrina disaster without coming right out and claiming global warming caused it was a little too clever for some atmospheric scientists but a group of…

Scientists analysing data gathered by Cassini have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as building blocks for more…

Scientists at Brookhaven National Laboratory have developed a new tool for quantitatively measuring elusive atmospheric chemicals that play a key role in the formation of photochemical smog. Better…

The first “State of the Carbon Cycle Report” for North America, released online this week by the U.S. Climate Change Science Program, finds the continent’s carbon budget increasingly overwhelmed by…

There are wide-ranging predictions about the coming solar cycle peak in 2012 and its influence on Earth's warming climate and the $88 million Solar Radiation and Climate Experiment(SORCE) mission,…
