the earth has been warming since the ice age. the conversation isn't the warming however what we should do. I am not sure that air pollution is the challenge. I will concede we have a ground pollution challenge. On air pollution, most what we here is about someone making money. Electric cars receive power from coal. plus the batteries are worse for us than gas and oil. Wind and solar are so expensive only the rich can afford. while many scream global warming they fly around the world for pleasure, drive big engine vehicles, have huge energy consuming houses, etc. As democrats do, it is about telling us what to do rather than leading by example. Our earth's biggest challenges come from poor uneducated countries.
every year democrats that cheer global warming take vacations to other countries, often multiple times. just had another democrat voting person I know buy a under 10 mpg vehicle.

We aren't at the warmest part of this interglacial period, that happened thousands of years ago.
