is announced from the 1970 years, a period when it was announced the disappearance of oil by the year 2000 !!
In fact, since the land was 10 times more CO2 in the past several times (there 55millions years in particular), it is certain we have enough varied fossil fuels underground to multiply our CO2 or even burn all our oxygen !!
So you have to reach this limit CO2, even if the current warming is not the CO2 entirely.
Oil and fossil fuels will not be limited to themselves by a peak and exhaustion, but by rising seas, which once well underway to becoming quite inexorable 2m per century, as there 15000 years, gone for relentless rise 7000ans and without CO2 at all !!

If we had lived there for 14000ans 8000ans with this inexorable rise, without having done anything to anything, the plains like the Baltic Sea and inhabited populated being submerged inexorably, it would have been a huge disaster, unable to do anything to avoid it on !!! 5 millennia.
It remains for the future over millennia inexorable rise of similar 5m (Greenland) and endless 70m (Antarctica melted) !!
In fact there will be a rise of half that passed, similar to 70m between 12000 and past 8000ans.
Stability spent on past 7000ans, miraculous, unique on 400000 recent years !!

It is certain that Africa will be demolished and devastated more by exploiting its wealth to our only advantage.
But with this rising seas, the devastation will be global and inexorable for millennia !!
We can already remove all the heating CO2 with storage of solar heat in summer ordinary soil to heat the winter for cheap! as this link.

I agree that we must be concerned about the rising water ... But it is not only related to the melting of glaciers but the moéculaire expansion. so I doubt very much that the level will rise as some claim. it would be contrary to the laws of physics. Besides the ice takes up more volume than water, so it takes the entire underwater portion of the ice will shrink in volume, which should lower the level for that portion there ...!
Then the saturation of the water in the air will increase by proportion, and this water will not mount seas, but will be in suspension. The land currently arride especially with the advance of the desert, also has a strong power of accumulation.
All these many points are not taken into account when we want to doom and gloom!
The man also can occur, channeling the water with large pipelines to bloom again desert areas. Désalinisant in sea water through solar thermal power plants ... Recovering = channeling water areas submerged by increased precipitation!
There are many things to do ... Over the long term.
For Co2, it is proven that over the rate increase, the plants love it and produce oxygen benefit ...
The real problem is the breeding and methane. Again, it does not mean that we should not reduce / control our emission sources ...
I am not as pessimistic overall, but act!
