GLOBAL WARNING...

Yes Global warming is caused by man.

References that say global warming is NOT caused by man...

• Global warming results not from the emission of greenhouse gases into the atmosphere, but from an unusually high level of solar radiation and a lengthy - almost throughout the last century - growth in its intensity...Ascribing Green House properties to the Earth's atmosphere is not scientifically substantiated...Heated greenhouse gases, which become lighter as a result of expansion, ascend to the atmosphere only to give the absorbed heat away.

GLOBAL WARNING

WHAT CAUSES GLOBAL WARNING?

1. Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up.
2. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually
3. Methane-
   While carbon dioxide is the principal greenhouse gas, methane is second most important. According to the IPCC, Methane is more than 20 times as
   effective as CO2 at trapping heat in the atmosphere.
   

HOW TO STOP GLOBAL WARNING..

1. By reducing pollution from vehicles and power plants. Right away, we should put existing technologies for building cleaner cars and more modern electricity generators into widespread use.

2. Install a programmable thermostat
   Programmable thermostats will automatically lower the heat or air conditioning at night and raise them again in the morning. They can save you $100 a year on your energy bill.

3. Fly less
   

4. Clean or replace filters on your furnace and air conditioner
   Cleaning a dirty air filter can save 350 pounds of carbon dioxide a year.
5. Recycle your organic waste
