Rocks Reveal North American Climate History


Growth rings on rocks give up North American climate secrets going back 120,000 years[more]

Greenland Ice Sheet Melts More When It’s Cloudy


Clouds help add mass to the ice sheet when it snows. Also, clouds block the sunlight, which lowers the temperature. At the same time, they form a blanket that keeps the surface warm, especially at night. A study examines the net...[more]

UAH: Expect More Warmth As El Nino Wanes


The atmosphere should continue to see El Nino-influenced high, even record high, temperatures for the next several months, says UAH's John Christy[more]

UAH Agrees With RSS Data: 2015 Third Warmest Year


UAH analysis of satellite data confirms RSS analysis in showing 2015 was the third warmest year in terms of atmospheric temperatures [more]

Clouds Double El Nino Amplitude


Climate model experiments suggest clouds enhance ENSO variability by a factor of two or more. Clouds induce heating in the mid and upper troposphere associated with enhanced high-level cloudiness over the El Nino region, and...[more]

Melting Antarctic Sea Ice Lid Released Ice Age CO2


Melting of massive Antarctic ice ‘lid’ resulted in huge release of CO2 at the end of the ice age [more]

Large Methane Emissions Seen In Northern Lakes


Measurements from 733 northern water bodies – from small ponds formed by beavers to large lakes formed by permafrost thaw or ice-sheets – enable researchers to estimate methane emissions over large scales[more]

Ice Sheet Firn Changes Reported In Greenland


Climate change is altering the way the Greenland ice sheet melts and accelerating sea level rise, claims a York University professor who has co-authored research showing that the layer of firn - compacted snow - on top of the ice...[more]

El Nino Past Peak Says BOM


A number of indicators suggest that the 2015-16 El Nino has peaked in recent weeks, according to Australia's Bureau of Meteorology. There is a 50-50 chance of a La Nina cooling event kicking in later in 2016[more]

NSIDC Data: December Arctic Sea Ice Fourth Lowest


Arctic sea ice extent in December reflected the pattern for the whole of 2015 - in line with levels seen in the last decade but also consistent with a long term decline[more]

RSS Data: Warmest December And Third Warmest Year


Atmospheric temperatures in 2015 ranked behind those reported in 2010 and 1998 although December 2015 was the warmest December in the satellite era, according to data from RSS[more]

Sensitivity Study: Recent Past Predicts Future Warming


Examination of Earth's recent history is the key to predicting global temperatures says a team of NASA researchers looking at the sensitivity of the climate to CO2 increases. They calculated the temperature impact of different...[more]
