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.

Bioenergy and biofuels have an important role to play in lowering the use of carbon-intensive fossil fuels – a point underscored by the IPCC report which confirmed the need for further research to improve such technology. 

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.

The 2014 State of the Climate report. a joint undertaking by the CSIRO and Bureau of Meteorology, found that Australia’s temperature is predicted to rise by 1°F to 2.7°F by 2030; in comparison, between 1910 and 1990 the temperature rose by 1°F.

Increasingly common false spring events are leaving crops and wild plants vulnerable to subsequent freezes, creating a cascade of consequences for ecosystems. The spring of 2012 was the earliest recorded across the United States since 1900.

The world faces a serious water crisis, warned former heads of government and experts recently in a book that identifies a multitude of associated security, development and social risks, including food, health, energy and equity issues.

The forests stretching from Mexico through Central America have some of the richest species diversity on the planet. But despite expansive conservation efforts, this region continues to face staggering rates of forest destruction

Recent signs that Barack Obama may approve the Keystone XL pipeline have some environmentalists feeling down about the future of the climate. But huge and positive changes are quietly taking place.

Painting building roofs white could cool some major cities baking in the intensifying heat of a changing climate. How much benefits white roofs could bring depend on the region of the country they’re installed in and the season, new research shows.

The question of how global warming will influence El Niño has been a challenging one for scientists to answer. A new study suggests while the overall number of El Niños is unlikely to increase, particularly strong “super” El Niños are likely to occur twice as frequently in a warming world.

A wildfire exploded outside Los Angeles Thursday as record temperatures spread across California, where drought conditions are escalating as the state comes off its driest year on record.A new update to the U.S. Drought Monitor shows that severe drought, the second-worst drought category, has spread across 62.7 percent of the California as of Tuesday.

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.

If we really believe that doom is a viable expression of the endgame, wouldn’t we try to resolve some of this thanatos by“wresting control of our lives” from an inherently sick society? Wouldn’t we want to resolve remnants of cognitive dissonance by making our day-to-day behaviors more congruent with our “talk”?

When I give these climate talks, by the end people are typically agitated and full of questions. “What technology is going to fix this?” “How are we ever get people to agree on a solution?” “I’m just one person, what could I possibly do that would make an impact?”

Many of the lessons learned are most applicable to those living in a similar climate to the Whole Systems Farm in Vermont; however, the farm’s thriving ecosystem has been created on marginal land, and Falk stresses that the concepts can be transferred to other locations where only marginal land is available and creative solutions are needed.

Our society's addiction to fossil fuels is not only polluting our skies and wreaking havoc on our climate - it's also threatening to kill one of mankind's most precious resources.
