Sentences with phrase «which cumulative carbon emission»

If we were certain that the ensemble mean warming represents the real climate systemt we could read out from figure 1c at which cumulative carbon emission we could expect to cross this threshold.

Not exact matches

Even the 350 - ppm limit for carbon dioxide is «questionable,» says physicist Myles Allen of the Climate Dynamics Group at the University of Oxford, and focusing instead on keeping cumulative emissions below one trillion metric tons might make more sense, which would mean humanity has already used up more than half of its overall emissions budget.

By framing the issue in terms of a carbon budget based around cumulative emissions, the IPCC's most recent report showed that it doesn't necessarily matter what short - term emissions reduction targets are adopted, or which country cuts emissions by a particular amount relative to another nation's pledges.

A global warming target is converted to a fossil fuel emissions target with the help of global climate - carbon - cycle models, which reveal that eventual warming depends on cumulative carbon emissions, not on the temporal history of emissions [12].

The long - term sea level rise will depend critically on the cumulative carbon emission pathway humans follow, which determines the sustained global warming that can be maintained for centuries to millennia.

Regarding text stating that limiting warming from anthropogenic CO2 emissions alone to likely less than 2 °C since 1861 - 1880 requires cumulative emissions to stay below 1000 gigatonnes of carbon (GtC), Saudi Arabia urged using 1850 for consistency, to which the CLAs responded that some model simulations only begin in 1860, which delegates agreed to reflect in a footnote.

This watershed, painstaking analysis traces emissions totaling 914 gigatons of carbon dioxide - equivalent — which amounts to 63 % of the cumulative worldwide emissions of industrial CO2 and methane between 1751 and 2010 — to 90 so - called «carbon major» entities worldwide.

Wasdell said that the draft submitted by scientists contained a metric projecting cumulative total anthropogenic carbon dioxide emissions, on the basis of which a «carbon budget» was estimated — the quantity of carbon that could be safely emitted without breaching the 2 degrees Celsius limit to avoid dangerous global warming.

Attributing Environmental Damage to Carbon Producers: Richard Heede, co-founder and director of the Climate Accountability Institute, presented a preview of a research project several years in the making, in which he has been quantifying the annual and cumulative global warming emissions attributable to each of the world's major carbon producers....

Translating this commitment into quantitative implications for cumulative carbon involves a lot of guesswork as to how China will go about fulfilling its commitment, because the agreement does not spell out the value at which emissions will peak.

This appears to me to comport with the «IEO2011 Reference case projects about 1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035» that you cited in # 143, which clearly states CO ₂ in the sentence.

Because all 2013 Intergovernmental Panel on Climate Change scenarios — except Representative Concentration Pathway 2.6 (RCP2.6), which leads to the total radiative forcing of greenhouse gases of 2.6 W m − 2 in 2100 — imply that cumulative carbon emission will exceed 1,000 Gt in the twenty - first century, our results suggest that anthropogenic interference will make the initiation of the next ice age impossible over a time period comparable to the duration of previous glacial cycles.»

>> The temperature response to which we are already committed at the present level of cumulative carbon emission is 3.9 °C (+ effect of non-CO2 GHG emissions) not 1.5 °C implied in the SPM

Each molecule of carbon dioxide, which is the most important long - lived manmade greenhouse gas, can remain in the atmosphere for as many as 1,000 years, making it more urgent to cut emissions in the near future, or face continued cumulative warming for centuries to come.

Cumulative carbon dioxide emissions after 2012 are 780 gigatonnes CO2 (Gt CO2), which is well within the IPCC's budget of 1,010 GtCO2 for maintaining a 66 % likelihood of keeping warming below 2 °C.
