gigatonnes

Combined, the two ice sheets dumped an average of 475 gigatonnes of ice which then melted into the ocean each year over the course of the study.

Ice sheets melting faster than earlier estimates 2011

But subtracting the carbon market reductions, the developed countries only reduce emissions by 1.9 gigatonnes.

After a hundred years, 420 gigatonnes will have been emitted, and if half that remains in the atmosphere (remember, rough estimates suffice to make the point here) the atmospheric stock of CO2 carbon will increase by 210 gigatonnes, or 30% of the pre-industrial atmospheric stock of about 700 gigatonnes of carbon.

Moreover and second, according to the Stockholm Institute Environment, developing countries are making more emissions reductions than developed countries: while developed countries are reducing emissions by 3 gigatonnes by 2020, developing countries are reducing emissions by 3.6 gigatonnes by 2020.

The biosphere pumps out 550 gigatonnes of carbon yearly; we put in only 30 gigatonnes.

Averaged over the 18 years of the study, the ice sheets lost a combined 36 gigatonnes more each year than they had the year before.

To have a likely chance of staying below 2 degrees of warming, the world will need to be producing emissions of no more than 44 gigatonnes GT CO2e by 2020.

Subtracting the carbon market reductions, the developing countries still reduce emissions by 3.6 gigatonnes, Sólon stated.
