Climate Science in Action

From researching the pace of Alaskan glacier melt to how changes in Arctic sea ice affect our weather, climate scientists go to some of the most remote areas on Earth to help us understand our environment. The Juneau Icefield Research Program (JIRP) brings scientists and students together annually to study glaciers. Jeff Barbee reports on…

2013 Is the Fourth Hottest Year on Record

By Phil Plait (Slate):  It’s official: 2013 is the fourth hottest year since records started being kept in 1880. It ties with 2003 for that dubious honor. This result was just announced by the National Oceanic and Atmospheric Administration. It uses global annual land and sea surface temperatures to make the call, and in 2013 these two measures combined…

Polar Vortex to Collapse and Flood Eastern US With Arctic Air

Robert Scribbler: Well, the forecast is in. And it appears we are about to receive yet another helping of winter weather extremes driven by human caused climate change. ECMWF and NOAA models both show mid and upper level warmth increasing over the polar region. This warmth, over the next week, will invade toward the surface, collapsing the…

Australia: Top temperature forecast to reach 46C | Heat stress | Power outages | Wildfires

Adelaide could break its 75-year-record for its hottest day – a searing 46.1C in January 1939 – after its warmest night in five years. The mercury only dropped to 29.9C just before 6:30am, with the temperature still above 35C at 2:00am. Acting regional director at the Bureau of Meteorology, John Nairne, says a new record…
