NASA's Six Decades of a Warming Earth

NASA scientists say 2013 tied for the seventh warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 133-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.

This visualization shows how global temperatures have risen from 1950 through the end of 2013.

Humans are influencing some extreme weather events, but not all

From EARTH Magazine  --  In 2012, the world experienced dozens of extreme weather events, including droughts, heat waves, cold spells, extreme rainfalls, big storms like Superstorm Sandy, and a record-low Arctic sea-ice extent. Teasing apart the factors that create extreme weather is a challenge for scientists, especially when it comes to determining whether human-induced climate change plays a role.

Ozone's Slow Recovery Google+ Hangout (Jan. 8)

From the American Museum of Natural History  --  How soon will Earth's ozone layer recover? In this online event, connect with NOAA scientists to explore a new data visualization about the 2013 ozone hole and predictions for recovery. Strategies for interpreting the visualization for educational audiences will be addressed.  The Hangout will highlight a newly released data visualization about the status of Earth’s ozone layer, designed for informal education at museums and science centers.

Is it climate or weather?

From CCAFS - With the record-low temperatures and severe winter storms hitting the United States and other parts of the globe, you are no doubt hearing reports calling attention and in to question "climate change" and "global warming."  But one of the challenges researchers face when communicating climate science is the distinction between climate and weather. The public and the media are often quick to conflate the two, resulting in confusion or worse, misinformation.

Currently, no difference in temperature between Canada and Mars

From Smithsonian Magazine  --  Even in northern Minnesota right now, the temperature has dipped to a staggering -42 F. The chill is running so deep in the North Star State that it’s not only colder than in the lands above the Arctic Circle, it’s actually colder than some of the daily temperatures on Mars—you know, the planet 78 million miles further from the Sun on average.
