Patterns of extreme weather are changing in the United States, and climate science predicts that further changes are in store. Extreme weather events lead to billions of dollars in economic damage and loss of life each year. Scientists project that global warming could affect the frequency, timing, location and severity of many types of extreme weather events in the decades to come.
America has virtually limitless potential to tap the energy of the sun. Solar energy is clean, safe, proven and available everywhere, and the price of many solar energy technologies is declining rapidly. By adopting solar energy on a broad scale, the nation can address our biggest energy challenges – our dependence on fossil fuels and the need to address global warming – while also boosting our economy.
America’s current fleet of gasoline-powered cars and trucks leaves us dependent on oil, contributes to air pollution problems that threaten our health, and produces large amounts of global warming pollution. “Plug-in” cars are emerging as an effective way to lower global warming emissions, oil use, and smog. A plug-in car is one that can be recharged from the electric grid. Plug-in cars come in two types: plug-in hybrids that are paired with small gasoline engines, and fully electric vehicles that consume no gasoline at all.
As world leaders prepare to meet in Copenhagen to develop a plan of action to combat global warming, all eyes are on the United States. As the world’s largest economy, the second-largest emitter of global warming pollution, and the nation responsible for more of the human-caused carbon dioxide pollution in the atmosphere than any other, the success of the Copenhagen negotiations – and the future of the planet – depend on American leadership.
