What is global warming? Global warming is the temperature rise that is unequivocally underway in Earth's atmosphere and oceans. With greater than 90% certainty, scientists have determined that global warming

What’s being done now to reduce our emissions? Solar Power Wind Power Fuel-Efficiency
We can stop global warming!
What can you do to help solve the problem?
Simple Things To Do Turn off your computer or the TV when you’re not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.
Be Bulb Smart—Use CFLs 500 lbs. of coal What’s the difference? Compact Fluorescent Incandescent
1,430 lbs. CO2 pollution avoided
Simple Things To Do Dress lightly when it’s hot instead of turning up the air conditioning. Or use a fan. Dress warmly when it’s cold instead of turning up the heat. Offer to help your parents keep the air filters on your AC and furnace clean. Walk short distances instead of asking for a ride in the car. Plant a tree. Recycle.
