Interesting weather fact.

happened many times over long before man even arrived.

Perhaps someone can explain which / what / how / where / when pollutants - which have most assuredly been created by man - got into the atmosphere and the waters of the earth before man arrived? When did this happen and how did it happen? Why would the leaders (highest leaders - presidents - premiers - prime ministers - etc.) of over 150 different countries go to Paris and spend a couple weeks trying to figure out what to do and eventually hammer out some sort of agreement - even the Pope is on board? Are all of these people and the world's leading scientists all complete morons? I simply cannot comprehend how anyone can say this has happened before. If man was not here then how did this pollution occur? It was cold before? It was hot before? That has nothing to do with what is going on today. That this is a man-made situation is a scientific fact. It is not a matter of agree or disagree. It is fact. Apparently there are those who choose to ignore facts. But ignoring them has never changed facts. That this happened before is not an answer because it most certainly has never happened before. People keep talking about weather and how it is cold or hot or rainy or snowy or whatever. Of course it has snowed before. And it has been hot before. The question is why these things happened then and why they are happening now. They are not talking about weather - though weather can factor in. There are boatloads of scientific facts to support the fact that this is man-made and that man can make a difference - bad or good.
