The tropical Pacific Ocean may be able to open a “vent” in its heat-trapping cirrus cloud cover and release enough energy to diminish climate warming. The clouds appear to decrease when sea surface temperatures are higher.

NASA-funded researchers have figured out why Lake Chad has shrunk from the size of Vermont to Rhode Island in the last 30 years. Both a drier climate and high agricultural demands for water are to blame.

A joint NASA and Canadian Space Agency mission now provides a more comprehensive view of how the Antarctic ice sheet moves and changes. The new radar map may help answer some fundamental questions about whether the ice sheet is advancing or retreating.

Newly discovered large nitric acid particles are helping scientists better explain ozone loss in the Arctic stratosphere. The newly discovered class of particles has given scientists a better understanding of the processes that set the stage for chlorine-caused ozone depletion in the Arctic.

Data from NASA’s Terra satellite has confirmed that this has already been a snowier than normal winter for parts of the United States.
