Sentences with phrase «stabilisation scenarios»
The phrase "stabilisation scenarios" refers to different plans or situations aimed at maintaining a balanced or steady state. It suggests strategies to prevent changes or fluctuations in a system, such as the environment or the economy, by implementing measures to keep it stable. Full definition
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.

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.
For a warming over Greenland of 5.5 °C, consistent with mid-range stabilisation scenarios (see Figure 26), the Greenland ice sheet is likely to contribute about 3 m in 1,000 years.
What we can see from stabilisation scenarios and the possibilities of positive feedbacks in the carbon cycle is that we don't have two decades to wait to get detailed information to enable us to make a near - perfect cost - benefit analysis.
Although the small number of impact assessments that evaluate stabilisation scenarios do not take full account of uncertainties in projected climate under stabilisation, they nevertheless provide indications of damages avoided and risks reduced for different amounts of emissions reduction.
1 - degree stabilisation scenario (the first I have seen), and sketches the actions for a 300 ppm target.
A more general review of the literature on climate change mitigation is found in the WGIII AR4 Chapter 3 (Fisher et al., 2007) Sections 3.3.5 (on long - term stabilisation scenarios), 3.5.2 and 3.5.3 (on integrated assessment and risk management) and 3.6 (on linkages between short - term and long - term targets).
These technologies exist in principle but have not been implemented, to reach a 1.5 C stabilisation scenario these technologies would need to be available sooner and on a larger scale argues Allen.
For the much lower stabilisation scenarios (category I and II, Figure 5.1), the equilibrium temperature may be reached earlier.
These portray the GMAT response for four CO2 - stabilisation scenarios by three dates in the early (2025), mid (2055), and late (2085) 21st century.
Uncertainty in the equilibrium climate sensitivity creates uncertainty in the expected warming for a given CO2 - eq stabilisation scenario.
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 →
Values beyond 2100 are for the stabilisation scenarios (see Section 10.7).
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.
Stabilisation scenarios are an important subset of inverse mitigation scenarios, describing futures in which emissions reductions are undertaken so that GHG concentrations, radiative forcing, or global average temperature change do not exceed a prescribed limit.
