It is beyond dispute that the world is warming.  Carbon dioxide and other greenhouse gases produced when fossil fuels, such as coal, gas and oil (i.e. in cars and power plants) are burned collect in the atmosphere, trapping the suns heat and causing the earth to warm.  Much of this greenhouse gas remains in the atmosphere for decades and translates into rising global temperatures.  Although temperatures fluctuate, predictions are that summer high temperatures will on average rise between 3º and 7º F and winter low temperatures will warm by as much as 5º F to the east and 10º F to the west.  If nothing is done to change the current level of greenhouse gas emissions earth will continue to warm.  

What can be done to address climate change?  We can dramatically reduce emissions of carbon dioxide and other greenhouse gases by making cars run cleaner and more efficiently (burning less gas), modernizing power plans, shifting to energy sources that don't use fossil fuels (i.e. solar, wind, etc), and cutting our energy use through energy efficiency (i.e. using more efficient appliances and conserving energy).
