Global Warming

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? Think of a blanket, covering the Earth.

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 all around the world—more extreme storms, more severe droughts, deadly heat waves, rising sea levels, and more acidic oceans, which can affect the very base of the food chain.

What causes global warming? We do.

The primary cause of global warming is human activity, most significantly the burning of fossil fuels to drive cars, generate electricity, and operate our homes and businesses.

Tropical deforestation, also by human hands, is another major contributor. When these forests are burned, they release huge amounts of carbon into the atmosphere and because the forests no longer exist, they are no longer available to absorb CO₂.

Who can reduce global warming? We can.

To address global warming, we need to significantly reduce the amount of heat-trapping emissions. As individuals, we can help by being mindful of our electricity use, driving more efficient cars, reducing the number of miles we drive, and taking other steps to reduce our own consumption of fossil fuels (Read Ten Personal Solutions to Global Warming for more great suggestions).

But we can also help by calling for government and corporate decision makers to reduce the threat of global warming by:

Placing limits on the amount of carbon that polluters are allowed to emit.
Investing in clean and efficient energy technologies, industries, and approaches;
Expanding the use of renewable energy;
Increasing the efficiency of the cars we drive ;
Reducing tropical deforestation and wildfire risks; and
Taking other steps to transform our energy system to one that is cleaner and less dependent on oil, coal, and other fossil fuels.
