Sentences with phrase «given greenhouse gas emissions scenario»

Not exact matches

«This is worrisome given that the temperature in the study region is predicted to rise by as much as 2 degrees by midcentury under the range of plausible greenhouse gas emissions scenarios,» said Avery Cohn, aassistant professor of environment and resource policy at Tufts, who led the work while he was a visiting researcher at Brown.

Climate change scenarios are based on projections of future greenhouse gas (particularly carbon dioxide) emissions and resulting atmospheric concentrations given various plausible but imagined combinations of how governments, societies, economies, and technologies will change in the future.

As well, greenhouse gas emissions turned out to be between Scenario A and Scenario B (CO2 is closer to B but Methane is closer to C), so that also gives them some wiggle room.

Here we present a new index of the year when the projected mean climate of a given location moves to a state continuously outside the bounds of historical variability under alternative greenhouse gas emissions scenarios.

And it would essentially give us an extra 10 to 15 years of greenhouse gas emissions before we become committed to 2 °C warming above pre-industrial levels, for example — in roughly 2038 as opposed to 2027 in Representative Concentrations Pathway (RCP) 4.5, which represents a scenario in which we slowly reduce our greenhouse gas emissions.

While these uncertainties prevent the establishment of a high - confidence, one - to - one linkage between atmospheric greenhouse gas concentrations and global mean temperature increase, probabilistic analyses can assign a subjective probability of exceeding certain temperature thresholds for given emissions scenarios or concentration targets (e.g., Meinshausen, 2005; Harvey, 2007).

That's in the IPCC AR4 Working Group 1, Summary for Policymakers, so one doesn't have to read very far to see what the IPCC actual projections are... that the projected trends are significantly lower than what Monckton claims and the fact that they are fairly scenario - independent over the next 20 years or so (which isn't that surprising given that it takes a while for the emissions in the various scenarios to diverge significantly and that half of the rise is projected to be due not to ANY additional emissions but simply to the greenhouse gases already present in the atmosphere).

Appendix II gives, in tabulated form, the values for emissions, abundances and burdens, and, radiative forcing of major greenhouse gases and aerosols based on the SRES1 scenarios (Naki» cenovi» c et.
