A large carbon sink in the woody biomass of Northern forests) determined that the «missing» sink was mostly in the Northern Hemisphere forests taking up about.7 gigatons C / year.

Not exact matches

The gap between what has been emitted and what can be emitted to give global warming a chance of remaining under 2 degrees C widens by another gigaton of CO2
Some environmental groups have called on rich nations to assess how much carbon the world can continue to emit while still having a shot of keeping temperatures below 2 C above preindustrial levels, and then make the case for using up whatever it cites as a «fair share» of those gigatons.
And achieving any stabilization target — whether 2 degrees C of warming or 450 ppm or 1,000 gigatons of carbon added to the atmosphere by human activity — will require at least an 80 percent cut in emissions from peak levels by the end of this century and, ultimately, zero emissions over the long term.
Since 1880, 531 gigatons have been emitted and emissions should not exceed 800 gigatons of C for a better than 50 - 50 chance at keeping global temperature rise below 2 degree C.) «We can not emit more than 1000 billion tons of carbon,» Stocker says, noting that the IPCC numbers on which such regional and global climate projections are made will be available to anyone.
An even shorter version is: It is getting warmer; CO2 is a greenhouse gas and so an increase in it will drive warming (logarithmically without feedbacks); we are taking many gigatons of C out of the earth and dumping it into the biosphere as CO2; the increase in CO2 and the change of isotopes in the C are consistent with the source being the fossil fuels we are burning.
This illustration, using figures from the most recent 2014 IPCC report, depicts that because only 800 gigatons of CO2 can be emitted by humanity before creating a 66 % probability that a 2 degree C warming limit will be exceeded and humans have by 2011 already emitted 530 gigatons of CO2, there are only 270 gigatons of CO2 that may be emitted after 2011 to limit warming to 2 degrees C. (For a more detailed explanation of these figures see, Pidcock 2013)
I thought emissions were measured in gigatons of CO2, not in degrees C or in meters, or in hours.
It turns out that 1,000 gigatons of carbon — 1 trillion tons — is roughly what it takes to warm the globe by 2 C.
Estimates of the total soil - carbon stock in permafrost in the Arctic range from 1,700 — 1,850 Gt C (Gt C = gigatons of carbon; Tarnocai et al., 2009; Zimov et al., 2006a; McGuire et al., 2009).
Notice the «Anthropogenic emissions (2010)» figure of 9.5 Gigatons of carbon per annum (GT C p.a.).
To have one chance in three of avoiding 2 C, we must not emit more than 880 gigatons of carbon to the atmosphere.
Annual CO2 sequestered by carbon capture and storage in gigatons (Gt) CO2 by year and SSP across all RCP1.9 / 1.5 C scenarios.
