Through burning fossil fuels, humans are rapidly driving up levels of carbon dioxide in the atmosphere, which in turn is raising global temperatures.

Groups have been divesting money from oil, coal, and gas for years. Now they’re hoping to get more climate-healing bang for their buck.

Global business can find good investments that also address climate change by looking to the world’s most vulnerable populations.

Combined, the People’s Climate March on Sunday followed by Flood Wall Street the next day, uplifted a narrative around climate change that was impossible for even the most mainstream of media to ignore. In the words of Fox News talking head James Carville, “It’s the economy, stupid.”

Despite what appears to be an insurmountable problem, it may be possible to significantly reduce global water scarcity in 35 years.

Two companies in Japan recently announced they are to begin building two huge solar power islands that will float on reservoirs. This follows Kagoshima solar power plant, the country’s largest, which opened in late 2013 and is found floating in the sea just off the coast of southern Japan.

The critical links between water, sanitation, and our global consumption of energy – the “energy-water nexus” are more obvious than ever before. But how many of us will take direct action at the most basic level of all?

Globally 1.2 billion people live in areas of water scarcity — defined by the United Nations as locations with an annual water supply that drops below 1,000 cubic meters per person.

The UK government’s senior adviser on science has made an entirely sensible call for researchers and policy makers to move the climate change debate towards workable strategies and solutions. The trouble is, the models we have for assessing those strategies are deeply flawed.

Reducing deforestation in the tropics would significantly cut the amount of carbon dioxide emitted into the atmosphere by as much as one-fifth, research shows.

Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. A new world record for solar photovoltaic efficiency had been set.

The “Meatless Mondays” campaign was originally thought up to support the war effort during World War I, but now a modern army is using it to fight an even bigger battle—the one against climate change. It's not just Norway where the military is concerned about climate change. Former United States army officer...

The majority of Americans believe that global warming is real. A fewer number believe that it is a threat and less still believe that it is caused by humans. These are really amazing numbers...

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. 

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.

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.
