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.

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

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.

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.

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.

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?

One of the world’s largest manufacturers of children’s toys will join the ranks of environmentally friendly companies. The LEGO Group announced in November it will sign on to WWF’s Climate Savers Program.

U.S. companies are in a position to start an amazing race for climate profits. This race won’t happen around the confusing streets of an exotic city, but inside the board rooms and under the factory floors of businesses across America. And the prize? Not a million dollars. But right now at least $190 billion with a B. Everyone who competes can win their share. 

Today Richmond is one of 29 participating cities in WWF's Earth Hour City Challenge. But in the 1970s and 1980s the situation was far different. Pollution from tobacco plantations and chemicals plants had sullied the river to the point where fishing in the James River was banned in 1975.

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.

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.
