Sentences with phrase «cumulative emissions of carbon dioxide»

His work has shown that limiting cumulative emissions of carbon dioxide may be a more robust approach to climate change mitigation policy than attempting to define a «safe» stabilization level for atmospheric greenhouse gases.
Instead, what's important is the cumulative emissions of carbon dioxide (CO2)-- since a single molecule of CO2 can linger in the atmosphere for as long as 1,000 years — emitted since the dawn of the industrial era.

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.
The United States is the second biggest emitter of carbon dioxide worldwide (and has contributed, with Europe, 52 % of the share of cumulative carbon emissions since industrialization).
It has been estimated that to have at least a 50 per cent chance of keeping warming below 2 °C throughout the twenty - first century, the cumulative carbon emissions between 2011 and 2050 need to be limited to around 1,100 gigatonnes of carbon dioxide (Gt CO2).
Finally, to revisit the question originally posed @ 203: Assuming the IEO2011 Reference case of «1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035», and given that this case equates to following RCP8.5 until 2035 as previously demonstrated @ 408, what increase in average global surface temperature relative to pre-industrial would result by 2035?
Assuming the IEO2011 Reference case of «1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035», and given that this case equates to following RCP8.5 until 2035 as previously demonstrated @ 408, what increase in average global surface temperature relative to pre-industrial would result by 2035?
IPCC AR5 summarizes the scientific literature and estimates that cumulative carbon dioxide emissions related to human activities need to be limited to 1 trillion tonnes C (1000 PgC) since the beginning of the industrial revolution if we are to have a likely chance of limiting warming to 2 °C.
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.
Cumulative carbon dioxide emissions should be calculated on a per capita basis for each country, so that every nation can shoulder a common but differentiated responsibility for climate change... Such a calculation «better reflects the principal of equity for developing countries»...
A carbon budget is the cumulative amount of carbon dioxide (CO2) emissions permitted over a period of time to keep within a certain temperature threshold.
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.
Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.
The U.S. Department of Energy's Carbon Dioxide Information and Analysis Center database pegs cumulative global emissions since 1751 at 1,323 gigatonnes of carbon dioxide (1,450 GtCO2e including meDioxide Information and Analysis Center database pegs cumulative global emissions since 1751 at 1,323 gigatonnes of carbon dioxide (1,450 GtCO2e including medioxide (1,450 GtCO2e including methane).
Overall, although natural gas is a non-renewable fossil fuel that emits carbon dioxide, the cumulative emissions saved by fuel switching over the next decade from coal to natural gas are likely to prove far cheaper than the removal of carbon dioxide from the atmosphere in future decades.
Overall the G8 pathway has cumulative carbon dioxide emissions (2012 — 2100) of 1,485 Gt CO2 for fossil fuels, and 125 for LUCF, with an additional 45 GtCO2 after 2100 assuming continued exponential decline.
The purpose of the «social cost of carbon» (SCC) estimates presented here is to allow agencies to incorporate the social benefits of reducing carbon dioxide (CO2) emissions into cost - benefit analyses of regulatory actions that impact cumulative global emissions.
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.
Specifically, the IEO2011 projects about 1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035 (page 143).
1 ppm CO2 = 2.12 Gt C (CDIAC) 2.12 Gt C = 7.76 Gt CO2 (C to CO2 ratio of 3.67, ThinkProgress) thus 1 ppm CO2 = 7.76 Gt CO2 «1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035» (IEO2011, p. 143) = 129 ppm of additional CO2 (divide 1,000 Gt CO2 by 7.76)
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.
The Carbon Majors website is based on ground - breaking research on 90 entities (investor - owned, state - owned, and government - run fossil fuel and cement producers) that are responsible for producing the fuels that have resulted in 63 percent of the global cumulative emissions of industrial carbon dioxide and methane between 1751 and 2010.
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.
