Sentences with phrase «co2 stabilisation scenario»

Last year, with the IEA World Energy Outlook 2010 we were happily surprised to see that the IEA still takes the 450 ppm CO2 stabilisation scenario seriously — indeed corresponding with the 2 degrees climate target that world leaders have agreed on multiple times.

Not exact matches

Nevertheless, climate sensitivity is part of the puzzle, and it particularly matters if you are interested in stabilisation scenarios, since it indicates what a particular equilibrium CO2 level will mean for equilibrium climate.

That would likely mean that also the official UN climate goal of limiting the average world temperature rise to no more than 2 degrees Celsius — a target linked to 450 ppm CO2 equivalent stabilisation scenarios (practically ambitious, theoretically weak)-- will eventually lead to many meters of global sea level rise.

RCP4.5 is a «stabilisation scenario» where policies are put in place so atmospheric CO2 concentration levels off around the middle of the century, though temperatures do not stabilise before 2100.

So - called stabilisation experiments have also been run with the atmospheric greenhouse gas concentrations increasing by 1 % / yr or following an IPCC scenario, until CO2 - doubling, tripling or quadrupling.

That would likely mean that also the official UN climate goal of limiting the average world temperature rise to no more than 2 degrees Celsius — a target linked to 450 ppm CO2 equivalent stabilisation scenarios (practically ambitious, theoretically weak)... Continue reading →

Uncertainty in the equilibrium climate sensitivity creates uncertainty in the expected warming for a given CO2 - eq stabilisation scenario.

Projected ranges of global mean annual temperature change during the 21st century for CO2 - stabilisation scenarios (upper panel, based on the TAR) and for the six illustrative SRES scenarios (middle and lower panels, based on the WG I Fourth Assessment).
