The Earth is warming and human activity is the primary cause. Climate disruptions put our food and water supply at risk, endanger our health, jeopardize our national security, and threaten other basic human needs. Some impacts—such as record high temperatures, melting glaciers, and severe flooding and droughts—are already becoming increasingly common across the country and around the world. So far, our national leaders are failing to act quickly to reduce heat-trapping emissions.
However, there is much we can do to protect the health and economic well-being of current and future generations from the consequences of the heat-trapping emissions caused when we burn coal, oil, and gas to generate electricity, drive our cars, and fuel our businesses.
Our country is at a crossroads: the United States can act responsibly and seize the opportunity to lead by developing new, innovative solutions, as well as immediately putting to use the many practical solutions we have at our disposal today; or we can choose to do nothing and deal with severe consequences later. At UCS we believe the choice is clear. It is time to push forward toward a brighter, cleaner future.
WHat is Global Warming?
When CO2 and other heat-trapping emissions are released into the air, they act like a blanket, holding heat in our atmosphere and warming the planet. Overloading our atmosphere with carbon has far-reaching effects for people everywhere. Learn more
Global Warming Science & Impacts
Global Warming Contrarians
Why has it been so difficult to achieve meaningful solutions? Media pundits, partisan think tanks, and special interest groups funded by fossil fuel and related industries raise doubts about the truth of global warming. These deniers downplay and distort the evidence of climate change, demand policies that allow industries to continue polluting, and attempt to undercut existing pollution standards. UCS fights misrepresentations of global warming, providing sound, science-based evidence to set the record straight. Learn more
Global Warming Solutions
Who can reduce global warming emissions? We can—together. Our individual efforts are important, but the biggest impact on climate change will come from large-scale changes—well-reasoned international, national, and regional policies; thoughtful, systematic efforts to reduce polluting fossil fuel energy sources and unsound land use practices; and steady progress toward a green, sustainable future.

Support Our Work
For more than 20 years, UCS has worked with leading experts to educate United States decision makers and the public about global warming, and implement practical solutions at an international, national, regional, and state levels. UCS recently helped defend California’s landmark global warming law from attacks by Texas oil companies. You can help support this work:
