Sentences with phrase «unabated co2»

So far, global warming / climate change has been relatively benign for many people (while anything but benign for others), but keep in mind that it is not yet as warm as it will be based on only the increase in CO2 so far, never mind that the increase continues unabated.
I speak not for allowing CO2 to go on unabated; rather I speak for engineering solutions to problems that enable CO2 control.
Pierrehumbert's prime concern (there are plenty more, all legitimate) is that any sun - blocking intervention done at climate scale would have to continue unabated for millenniums, or until CO2 removal was in high gear — or risk climatic whiplash if veils of reflective materials dissipated.
Of the many heat - trapping gases, CO2 puts us at the greatest risk of irreversible changes if it continues to accumulate unabated in the atmosphere — as it is likely to do if the global economy remains dependent on fossil fuels for its energy needs.

Warming would continue unabated, even under the most vigorous CO2 elimination schemes.
At the time of the session, there was a lot of discussion in the media over the growing realisation that global temperatures seemed to have «paused» for the last 10 - 15 years, even though CO2 emissions had been continuing unabated.
Unexpectedly (i.e. not predicted), global temperatures flat - lined and CO2 emissions continued on their merry, amazing growth path, unabated.
IOW something (which we can not explain as yet) is causing the recent «pause» in warming despite unabated human CO2 emissions; and this «something» may just continue for a while.
However you slice it, lolwot, there is a current «pause» (or «standstill») in the warming of the «globally and annually averaged land and sea surface temperature anomaly» (used by IPCC to measure «global warming»), despite unabated human GHG emissions and CO2 levels (Mauna Loa) reaching record levels.
How» bout we respond with: «the same mechanism that has caused the observed recent decade of slight cooling despite unabated human CO2 emissions and concentrations reaching record levels»?
Manacker, this argument «observed recent decade of slight cooling [of surface temps] despite unabated human CO2 emissions and concentrations reaching record levels» would be relevant if it was posited that CO2 is the only influence on climate.
from Mann et al: Esoteric and academic arguments about the response of the atmosphere to a doubling of CO2 may be interesting for those steeped in the peer - reviewed literature, but for the public and policy makers the important and unfortunate fact is that climate change is continuing unabated.
Esoteric and academic arguments about the response of the atmosphere to a doubling of CO2 may be interesting for those steeped in the peer - reviewed literature, but for the public and policy makers the important and unfortunate fact is that climate change is continuing unabated.
For instance, the global average temperature (as reported by NOAA, Hadley / CRU and NASA / GISS ground - based measurements, as well as RSS and UA - H satellite based measurements) has failed to increase in the 21st century the way the General Circulation Models have said they should despite the fact that CO2 has been rising unabated.

For convenience scientists often consider a standard forcing, doubled atmospheric CO2, because that is a level of forcing that humans will impose this century if fossil fuel use continues unabated.
The ocean's absorption of anthropogenic CO2 has already resulted in more than a 30 % increase in the acidity of ocean surface waters, at a rate likely faster than anything experienced in the past 300 million years, and ocean acidity could increase by 150 % to 200 % by the end of the century if CO2 emissions continue unabated (Orr et al. 2005; Feely et al. 2009; Hönisch et al. 2012)
