Climate Change is real, man-made, and happening now. The stakes are too high not to act.




Ninety-seven percent of climate scientists agree: Man-made climate change is a reality. In early 2014, two landmark reports spelled out the reality of the challenge we face. The Intergovernmental Panel on Climate Change and the National Climate Assessment both showed that, left unchecked, climate change has the potential to affect Americans everywhere—no matter where they live.



Every region of the United States is already experiencing the effects of climate change. If we don't act to curb current global emissions, they could lead to a global temperature increase of over 4 degrees Celsius (7.2 degrees Fahrenheit) by 2100—a scenario widely considered a global catastrophe, contributing to extreme weather, food and water shortage, and global instability.


Carbon pollution causing climate change is responsible for air that can be unhealthy to breathe, contributing to health risks for many children. Over the past three decades, the percentage of Americans with asthma has more than doubled and climate change is putting those Americans at greater risk of landing in the hospital.

The greatest obstacles we face in the fight against climate change aren’t technological or economic—they are political.


More than 130 members of Congress still refuse to acknowledge the scientific reality of climate change, and their denial is costing us time we can’t afford to waste. Organizing for Action is putting unprecedented pressure on climate change deniers in Congress, demanding a recognition of the facts, and changing the conversation about climate change.


OFA supporters aren't letting deniers try to continue a settled debate—read about the climate change denier awards, when OFA volunteers delivered unicorn trophies to deniers' offices in “honor” of their fantasy-like views on climate science.

Fight the deniers


The President has announced a new set of carbon pollution standards on new and existing power plants—a monumental step toward reducing the carbon pollution the United States generates.


His plan will reduce carbon pollution from existing power plants 30% from a 2005 baseline by 2030. That's a big deal—The New York Times called the President's climate proposal “the strongest action ever taken by an American president to tackle climate change.”

Stand with the President


We don't need to choose between clean air and a strong economy. President Obama's plan means more investments in solar, wind, and other forms of renewable energy. This investment will grow our economy and strengthen our communities, while also helping combat the effects of climate change.


The cost of solar panels has dropped 75% since 2008. There is now enough solar power produced in the United States to power 3 million homes.


United States wind power capacity has tripled since 2008. Today, 15 million homes can be powered by wind energy.
