In the wake of a Missouri grand jury’s decision not to indict Darren Wilson, the police officer who shot and killed Michael Brown, it can be difficult to imagine a place where law enforcement and a racially diverse population work together productively in the United States.

For several years now climatologists have puzzled over an apparent conundrum: why is Antarctic sea ice continuing to expand, albeit at the relatively slow rate of about one to two percent per decade, while Arctic sea ice has been declining rapidly?

Dire warnings of imminent human-induced climate disaster are constantly in the news but predictions of the end of the world have been made throughout history and have never yet come true.

The newly released National Climate Assessment spans 30 chapters with thousands of references on how climate change is impacting the U.S. The report took more than 300 scientists and 4 years to prepare, including addressing more than 4,000 comments from the public. The message of the report is that climate change is already happening across the country.

Parts of ancient Antarctica were as toasty as today’s California coast, say scientists who used a new method to measure past temperatures. The study focused on Antarctica during the Eocene epoch, 40 to 50 million years ago, a period with high concentrations of atmospheric CO2 and consequently a greenhouse climate.

Can the U.N. Intergovernmental Panel on Climate Change most recent report or a star-studded Showtime mini-series change the way people talk and think about climate change? Katharine Hayhoe urges her fellow climate scientists to ramp up their messaging game.

Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast section of the ice sheet is no longer stable. This means global sea levels may rise even faster than was previously anticipated.

In his complaints against the wing of the Republican Party that engineered the present government shutdown, Senate Majority Leader Harry Reid derided his opponents as “Tea Party anarchists.” It’s hard to decide who should be more annoyed — the Tea Party or the anarchists.
