CO2 in +300Million years....

Interesting ... in the AIT there was an impressive graf from last 600 000 years about CO2 levels (analysed from ice samples). The graf showed clearly the brutal fact - we are causing an exceptional period of rising CO2 and avarage temperatures.














In yesterday's Hesari (Hesari absolutely rocks - I appreciate HS's professionalism in educating and keeping us uptodate more and more every day ;o) there was another very interesting graf from the last +300 Million years (analysed from polar ice and stone deposits with radiometric dating). The theory is that rising levels of CO2 have always meant larger extinction of spieces.
It looks like in real earthly time scale (not in human scale since we are only about few 100 000s of years old) we are nowhere to levels of Co2 our home has been going thru earlier ... BUT if it all goes like predicted at year 2100 we will be at same level of CO2 when the dinosauruses died.
