there is no denying the excessive carbon dioxide emissions produced by the modern industrial age have had their effect on warming.
I love when people say this. I can deny it and you can't stop me.
When the oceans warm, they release CO2. It's obvious when you look at plots of warming cycles superimposed on CO2 levels.
theres LOTS of frozen ice at bottom of oceans...warm it up, CO`2 frozen in will come out, will rise... cooling of the land surface by just a few degrees will cause ice on land areas, glaciers...lot of volcano activity over years will cause ice age...but naaah, that never happened...must be man made....
and just because Al says CO2 will rise with temperature in the air, doesnt mean its so...temperature can also rise with CO2 levels....so which is it?
are we "contributing"? yes, how much? Nobody knows...does it have an impact? hmmm ...
If I gave $1 to George Bush`s campaign , did I contribute? YES
