Sentences with phrase «term average emissions»

Taking account of their historic responsibility, as well as the need to secure climate justice for the world's poorest and most vulnerable communities, developed countries must commit to legally binding and ambitious emission reduction targets consistent with limiting global average surface warming to well below 1.5 degrees Celsius above preindustrial levels and long - term stabilization of atmospheric greenhouse gas concentrations at well below below 350 p.p.m., and that to achieve this the agreement at COP15 U.N.F.C.C.C. should include a goal of peaking global emissions by 2015 with a sharp decline thereafter towards a global reduction of 85 percent by 2050,

The COP, by decision 1 / CP.17, noted with grave concern the significant gap between the aggregate effect of Parties» mitigation pledges in terms of global annual emissions of greenhouse gases by 2020 and aggregate emission pathways consistent with having a likely chance of holding the increase in global average temperature below 2 °C or 1.5 °C above pre-industrial levels.

The annualised average growth rate in global CO2 emissions over the last three years of the credit crunch, including a 1 % increase in 2008 when the first impacts became visible, is 1.7 %, almost equal to the long - term annual average of 1.9 % for the preceding two decades back to 1990.

Its revised projection indicates that if we stick with business as usual, in terms of carbon dioxide emissions, average surface temperatures on «Earth by 2100 will hit levels far beyond anything humans have ever experienced.

Projected global average temperature rise above pre-industrial levels under a range of future scenarios, «business as usual» (BAU), which assumes no mitigation efforts are made (RCP8.5); «mitigation», which assumes moderate emissions (RCP4.5) without negative emissions, «carbon dioxide removal» (CDR), which assumes moderate emissions with long - term CO2 removal; and «solar radiation management» (SRM), which is the same as the CDR pathway but also includes enough SRM to limit temperatures to 1.5 C by 2100.

org, US reductions need to be much greater than average reduction levels required of the entire world as a matter of equity because the United States emissions are among the world's highest in terms of per capita and historical emissions and there is precious little atmospheric space remaining for additional ghg emissions if the world is serious about avoiding dangerous climate change.
