A very disturbing report from Australia. Page 5, if the math is correct, for any one of the curves spells disaster. Geometric progressions increase very rapidly after the first three or four doublings.

Had the proposed Australian reduction of 5 percent in the rate of carbon
emissions by 2020 relative to 2000 [9] been a figure adopted world-side, global
emissions would be reduced from ~24,000 million tons/year to 22,500 million
tons/year, hardly causing a dent in the current trajectory above 393 ppm CO2
toward levels at which the polar ice sheets are further destabilized (Figure 3).
It is not clear whether deep reduction in carbon emissions will be sufficient to
stem the amplifying feedbacks associated with greenhouse gas warming and
ice/melt water interactions. Barring an indefinite maintenance of sulphur aerosol
emissions, deep emission cuts need to be accompanied by atmospheric CO2
draw-down by means of fast-track tree planting, application of biochar methods
and chemical CO2 sequestration. As shown by the intensifying spate of extreme
weather events around the globe (Figure 7) the alternative bears no
contemplation.
