Seems like some people were taught that science is mostly based on personal beliefs.

Fact: The thermometer with a standardized scale is only 125-150 years old.
That's a lot of extrapolation to take the last 150 years of small amount of data in a few places and extend it over thousands or millions of years. .
However, the one climate change which is human caused is local, and TV is a perfect example. TV was once green with a historical heat absorbing index of 1 (naturally designed) . . now its heat absorbing with asphalt and cement coverings and buildings. These items are heat sinks during the day, and is now way higher than the historical 1 for grasslands. . . This man made activity causes local global warming, and potentially, has gone / may have gone past the tipping point of affecting the entire planet
So building head absorbing structures in hot climates has nothing to do with CO2. . its just the only extrapolation that can go back long enough to scare everyone if you believe in extrapolation. . .
enjoy our man made heat. .
