While current efforts in Washington stand to undo climate change policies, nearly half America’s largest companies are emerging as leaders in setting clean energy targets that will reduce the amount of heat-trapping gases released into the atmosphere and help to curb climate change.

The average American spends 52 minutes a day commuting. And it pumps tons of carbon dioxide—literally—into the atmosphere every year. But there are quite a few ways to lighten commuting's toll.

Climate Crowd, an online platform for crowdsourcing data, helps us learn how rural and indigenous communities around the world are responding to climate change, among other things.

Congress and the new Administration must continue to make action on climate change a priority, both at home and abroad. Here's how they should do so.

In one of the most climate-vulnerable countries on Earth, an unprecedented development project is building a model for adapting to climate change on a massive scale—working one village at a time.

More than 4 million people call Nepal’s Gandaki River Basin home.

Eleven months ago, nearly 200 nations signed on to the first truly global agreement to curb climate change. And now that deal is officially entering into force. The agreement's enactment marks an auspicious start to the next round of climate negotiations that will take place this month in Morocco.

Crowdsourcing is a way to find solutions to problems by asking a large group of people to contribute information, ideas, data, and content about a certain idea. WWF is using this tool to address knowledge gaps about climate change, and help implement solutions.

Fishers in Mozambique have noticed changes in catch size and ocean currents as a result of a changing climate. WWF and partners are working to restore and protect the natural resources on which local fishing and farming communities depend.

After weeks of negotiations, 196 nations approved a landmark global plan to curb climate change in the years to come. By its design, the Paris Agreement creates the opportunity for nations to continuously strengthen their climate actions over time.

The interaction between climate and oceans is altering, and the exchange is intensifying. As the climate responds to decades of increasing carbon emissions, the store of energy and heat from the atmosphere builds up in the ocean. If we reach a tipping point, we will likely see more extreme weather events, changing ocean currents, rising sea levels and temperatures, and melting of sea ice and ice sheets.

If we act on climate change now, a safer and more prosperous future is within our grasp. Later this month, heads of state from around the world will gather in Paris to decide whether to actively work toward that prosperous future or whether to keep the status quo and hope for the best.

On August 31, 2015, President Obama and leaders of the Arctic nations met in Alaska where they pledged to work together, and with others, to boost strong action on climate change.

Wildfires have burned over vast areas of the planet this year. We have seen the dramatic images of the fires and their aftermaths. The smoke has drifted across continents and oceans—sometimes with serious consequences.

Cities are taking climate change seriously and setting ambitious action to cut greenhouse gas pollution and protect their residents from extreme weather and other climate hazards. A new report co-authored by ICLEI USA – Local Governments for Sustainability and WWF quantifies just how big city action is and can be in the US.

Last night’s State of the Union Address was critically important in a year when there will need to be major international agreement on climate change action.

Have you ever experienced the excitement of getting ready to run a marathon after months of training and preparation? Well, that's exactly how I felt today as I arrived in Lima, Peru, for the next round of UN climate talks. Over the next few weeks, I'll be joining my WWF colleagues on the ground in Lima to encourage international leaders to take bold and necessary climate action

It’s no question that climate change is one of the greatest challenges of our time. But here’s the good news: world leaders are taking note and working together to make concrete strides to a more prosperous future.

Forty percent. That’s the stunning population loss for polar bears in the southern Beaufort Sea. The news comes from a new study linking the dramatic decline in this polar bear subpopulation in northeast Alaska and Canada to a loss of sea ice due to climate change.

The commitments do represent important leadership, but there is still much work to be done to protect our species and the species we share this planet with from the worst effects of climate change.

To increase chances of conservation success, we must understand traits that make an individual species especially resilient or vulnerable to changes in climate. Different species will be affected in different ways; sometimes negatively, but not always.

Our energy choices make a difference. Not just in our homes but for polar bears, snow leopards and every species. Fortunately, solar provides a clean and abundant source of energy. All over the US, people are saving money and the planet by going solar. Learn how with this infographic.

Extreme weather events, melting glaciers and rising sea levels—all with links to climate change—are impacting the United States and the world, according to a new report by a group of leading US scientists and released by the White House on May 6.

Earth Hour is just the beginning. You’ve shown the planet you care by turning your lights out for one hour. So what’s next?
