We have changed energy sources several times in the past. We went from wood (after clear-cutting huge areas!) to coal, and then to whale oil, then to petroleum and gas. Each time things have gotten better economically.

Changing to renewables is required for two very strong reasons, and by eliminating the huge health costs of burning coal and oil, we will save a lot of money, and create many new jobs. We won't have to ever transition to another energy source after renewables. If we survive this long, we'll have to find another planet to move to in a billion years or so, when our sun moves into it's helium stage.

The two reasons we have to change over to renewables is that oil and coal are finite and they'll run out in a 100-150 years anyway (at our current use at least) - and climate change. Carbon dioxide is an insulator, and more of it means more heat is retained - that's physics.

All the people on my list are scientists - I believe they are mostly. if not all PhD's. Besides, 97% of all climate scientists agree that climate change this time around is caused largely by us humans burning fossil fuels.

We know that the increase of carbon dioxide in the atmosphere is carbon 12 isotope. That means it cannot be volcanoes (which would be carbon 13) and it is not burning of plants (which would be more carbon 14). And the level of oxygen is down, which is because of the combustion. This is direct physical evidence that shows that burning fossil fuels is the cause of the increase of carbon dioxide in the air. Period.

It cannot be explained any other way. Next question?
