there is a
90 percent chance that global warming is human-caused.


" While humanity's three billion
tonnes (gigatonnes, or GT) per year net contribution to the
atmosphere's CO2 load appears large on a human scale, it is actually
less than half of 1% of the atmosphere's total CO2 content (750-830
GT). The CO2 emissions of our civilization are also dwarfed by the
210 GT/year emissions of the gas from Earth's oceans and land.
Perhaps even more significant is the fact that the uncertainty in the
measurement of atmospheric CO2 content is 80 GT -- making three GT
seem hardly worth mentioning."
