10. Climate change is real. The earth is getting warmer.

 

Simply put, CO2 is a greenhouse gas. That means it will trap heat in the atmosphere. Human activity has increased its proliferation in the atmosphere by 40% in the last 150 years. The atmosphere is warming.

What you observe is weather. It's cold in the winter. Hot in the summer. Climate is a longer term trend, usually calculated in thirty year rolling mean to iron out "noise" variations. Its advance is chaotic, but its increase is hard to deny. (Though there are those who do.)

Your concepts of astronomy are a bit off. For one, the earth is always falling toward the sun. That's what keeps its orbit "stable."

Here's a good site for information. http://www.skepticalscience.com/
