I'm pretty concerned about the pictures of arctic ice melt over the past years. It seems to be pretty bloody drastic!
Jeds I am not expert and often though that the world was b*****r even if it went zero carbon emissions right now
No.
C02 is believed to have been as high as 5000ppm at some points.
It is currently <400ppm.
Climate change is that, climate change.
It will be disastrous for some coastal cities (possibly), some areas may see less rain, some more, these places could be where we currently grow crops.
We can pump as much c02 as we want it will never make the earth uninhabitable, and may make it more plant life abundant, but just in areas we currently don't grow our crops (which could lead to short term food shortages).
I don't buy that climate change will lead to greater storms either, http://wattsupwiththat.com/2011/06/26/global-hurricane-activity-at-historical-record-lows-new-paper/
According to a new peer-reviewed research paper accepted to be published, only 69 tropical storms were observed globally during 2010, the fewest in almost 40-years of reliable records.
Climate change is only potentially disastrous, because we have built all our major cities on the coast, and intensively farm our crops in the temperate belt (which will move north/south).
