Obviously things have warmed up a bit since then and yet where was man? Perhaps the fire he was cooking his wooly mammoth burger on is to blame. Come on.

The earth has warmed up since the mid 70's. That is about 30 years. The earth has been much warmer in the past then it is today and there have been much higher and much lower concentrations of CO2 in the atmospere during those warm cycles.

In the early 70's scientists believed we were on the edge of a new ice age!

In modern history, scientific theory was just that. 'Theory'. Until science proved or disproved the theory. Today, for the first time in modern history, theory is being accepted as science. Despite the many scientists and the science that disproves the 'theory'.

It is obvious that the earth is warming. Is there one single damn thing we can do to effectivley stop it? No. Are we the cause of it? No. The amount of CO2 produced by humans has been proven to be less than 1% of the total. Has Co2 been proven to be the cause? No. In fact the opposite is true. During past ice ages (and science has proven there to be literally thousands) CO2 levels have been much higher and much lower than the level recorded today.

There are two sides to the 'man made global warming theory.' Unfortunately 'also' for the first time in modern history, scientists who do not buy into 'humanity' as the cause are finding their funding cut off. Do a google search for the over 2,000 United Nations scientists who disagreed with the UN announcement naming man as the cause and asked to have their name stricken from the report.

I am not saying I know the cause. But I do know this. When someone tells me over and over and over what I should believe, it reminds me of Hitler's famous statement (and this isn't word for word but you will get the general gist), "tell the people a lie enough times and they will come to believe it."

And to the OP. The weight of the ice that has melted from both poles would (according to Einstein) possibly be enough to cause a wobble of the earth on it's axis. This ice, in areas is over a mile thick and almost 2 miles!. I believe we are talking much more weight wise than that of all man made structures.

30kyo? uh, also before that, and before that, and before that, and before that. glaciation is a cycle. the earth has been warmer, and colder, in the past. the point is to identify a trend across those cycles. we're not charting climate just from 50,000bce-->current.

those 70s scientists were correct - we are , by definition , in a period of snowball earth right now. arguing over "theory" is arguing semantics. big bang, relativity, plate tectonics, etc, are all "just theories".

you have got your facts mixed. the latest panel of scientists, in paris, declared to the contrary of what you claim. and we arent whistleblowers - scientists put their names behind their work.

you have the right to choose what you believe. even if it goes against the body of science. the remarkable thing about hitler is that many listened to him, and few opposed. but how you bring hitler into a discussion about science is beyond me.
