When was there :confused: the phenomenon of global warming for the first time in the fumigation

So, 10,000 years ago when there was an episode of global warming, was the burning of fossil fuels the cause? Was that your question? The word you used, "fumigation" has me a bit perplexed.

I mean Evaporation not fumigation" sorry

Is it combustion of fossil reason ? This is the first time that I hear that
What about pollution?

Anyway thanks very much for your Answer

That is what the media and many scientists are telling us. That the burning of fossil fuels are depleting the ozone layer of our atmosphere and contributing to global warming.

Someone I know could explain what is happening. His main point to me is that if our behavior is causing global warming today, how did it come about 10,000 years ago?

Evaporation is a liquid heated until it becomes a gas, like water to steam.
