With the collapse of the Copenhagen talks, the presumption of the developing nations that they have the right to burn as much carbon per capita as the developed nations, and the dismal failure of existing carbon reduction schemes to reduce output by any more than a token, the reality is that rising CO2 levels may only be slowed not stopped.

The question is then, what would the world look like, and what can we do to survive it? To prompt this discussion I have included below a graph of CO2 levels over the millennia:

Notice that about 300m BC the CO2 levels were about where they are now (300ppm), and 150m BC they were at 2000ppm.

Did temperatures rise?
Did Sea levels rise?
Was life extinguished?

Yes, the whole climate change, global warming, call it what you like, is so confusing it is little wonder there are so many sitting on the fence.

If only they could predict the future, rather than map the past.

"Was life extinguished?"

Obviously "life" wasn't extinguished, but conditions that bring about the flourishing of one form of life, may decimate another.

Here's the wiki page on the Carboniferous Period. It's helpful to compare the conditions at the time when amphibians were the dominant terrestrial species (before the evolution of reptiles) Sea levels were also affected by major tectonic movement...so a whole lot of factors which differentiate that time of earth's evolution with the present.

http://vimeo.com/16219493 'What in the World are thet Spraying' There is now solid evidence that the US Military is conducting experiments that affect weather.They are spraying nano sizes compounds of Aluminium, Boron and Strontium to change the weather under the guise of reducing global warming.

All these intense storms in the USA may not be to due to natural weather but weather manipulation by man.The evidence is extensive and Obama's science Tzar John Holdren, is on record saying that this type of climate/weather interference is a serious consideration.

The Military have interest in weather manipulation because this can have a huge effect on the battle field.

SM,

Interestingly, something termed the Carboniferous Rainforest Collapse occurred late in the Carboniferous period.
