research: CO2 is heavier than air. 1.5 times heavier, so where is CO2? at the lowest ground level possible. It's lke pigs could fly if they weren't so heavy, IF CO2 is heavier, it is not "up" in the atmosphere. If you fill a ballon with water does that make it float in air? So CO2 at ground level is absorbed by all living plant material to release Oxygen, and the plants absorb the Carbon. This is simple chemistry 101. So now What is the Argument? While we had 99 degree weather from July 2 until October 1, it was not as high as an occasional108 this year in Los Angeles county. It is so easy to believe that the Sky is falling if we are told enough times. so why this scam? To turn off America, turn off the lights when you leave the country.
