What does the shrinking of the Colorado River mean for Native American religions?
Historically, indigenous peoples used the natural seasonal cycles of weather, plants and animals as part of their religious calendar. What will be the impact of climate change on their practices?
A new paper improves our estimate of the climate’s sensitivity to carbon dioxide.
A new analysis suggests that weather records have not yet had time to capture the full effects of climate change, some of which are likely to take centuries to play out.
Best-case scenario, how much are we locked into?
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
Protests at the Brandenburg Gate, in Berlin, against the US withdrawal from the Paris climate change deal.
An expert report shows that the G20 countries are using their energy more efficiently. But there is still a long way to go.

Action on climate change is now increasingly in China's hands, and the decisions the country's leaders make in the next decade will have a profound global impact.
Water mass enters the ocean from glaciers such as this along the Greenland coast.
Greenland's ice is largely responsible for the accelerating pace of sea-level rise. A new analysis shows that, while Greenland accounted for just 5% of the rise in 1993, that figure rose to 25% by 2014.
Solar radiation management involves spraying tiny reflective particles into the upper atmosphere to reflect away some of the energy from the sun
Solar radiation management might be able to reduce some of the risks of global warming while countries get their emissions under control.
Diversity, resilience, resistance to disease: seeds must be preserved to ensure we can feed our world in the future.
Ice cores are a window into the past hundreds of thousands of years.

The current rise in atmospheric carbon dioxide levels is unprecedented in the past 800,000 years. As our video explains, ice cores track human changes to the atmosphere that are far beyond natural.

While many people are willing to happily gamble with pharmaceuticals, which may offer the most trivial of benefits, they are not ready to believe the facts on climate change.
A pre-industrial climate benchmark generally indicates before the Industrial Revolution – but that still leaves a very wide field.
The Paris climate agreement aims to keep restrict global warming to within 2℃ above 'pre-industrial levels'. But what does that mean, exactly?
Children hold signs at the C40 Mayors Summit in December 2016. Coalitions of local government are increasingly playing a significant role in combating climate change.
As the US leaves the Paris accord, how much faith should we put in international treaties? States, cities and local movements are increasingly important players in the fight against climate change.
A wide range of industrial processes have released greenhouse gases into the atmosphere.
While the gases most responsible for global warming - carbon dioxide, methane and nitrous oxide - continue to climb, other industrial greenhouse gases are being brought gradually under control.
Protestors gathered in D.C. on April 29 for People’s Climate March.
The White House is deciding whether or not to stay in the Paris climate agreement. But a large majority of Americans – including Trump voters – want the U.S. to participate and lead.

What if extreme weather events could be attributed to human-induced climate change with confidence?
The tropical Pacific has a large say in how fast the world warms.
If the Pacific Ocean enters an 'El Tio' phase, it could speed the world towards 1.5 degrees of global warming, one of the crucial benchmarks of the Paris Climate Agreement.

This summer sees the release of Al Gore's An Inconvenient Sequel: Truth to Power.
Bill Nye the Science Guy leads a crowd of scientists in the April 22 2017 March on Science in Washington, DC.
Scientists from Africa, Asia, Latin America and Europe take on the White House with facts from the ground they stand on.
When the environment and businesses meet, who will make sure one doesn’t suffer at the hands of the other?

Though business and industry are significantly contributing to climate change, business schools across the country are not preparing our future leaders for the dramatic shift this planet needs.
This year’s bleaching has mainly affected the Great Barrier Reef’s central region.
For the first time the Great Barrier Reef has been hit by mass bleaching in consecutive years, with only the reef's southernmost stretches having escaped both events unscathed.
