Sentences with phrase «stabilisation level»

It is also worth remembering that the earlier we start cutting emissions the cheaper it will be to do so and we will also be able to reach a lower stabilisation level for CO2 in the atmosphere.

Limited and early analytical results from integrated analyses of the costs and benefits of mitigation indicate that they are broadly comparable in magnitude, but do not as yet permit an unambiguous determination of an emissions pathway or stabilisation level where benefits exceed costs.

The topics addressed include critical thresholds and key vulnerabilities of the climate system, impacts on human and natural systems, socioeconomic costs and benefits of emissions pathways, and technological options for meeting different stabilisation levels of greenhouse gases in the atmosphere.

Third, the costs of action for any given stabilisation level rise rapidly if action is delayed.

The timing and level of mitigation to reach a given temperature stabilisation level is earlier and more stringent if climate sensitivity is high than if it is low.

Costs are relative to the baseline for least - cost trajectories towards different long - term stabilisation levels.

So any country whose government acknowledged in 2009 that CO2 emissions must reach net zero by the time temperatures reach the target stabilisation level of 2 °C should be 10 % of the way there now.

Token reference to a 1.5 ° C stabilisation level is meaningless to Africa as long as we remain so far from targets that are consistent with having half a chance of remaining below 2 °.

Uncertainty in the carbon cycle feedback creates uncertainty in the emissions trajectory required to achieve a particular stabilisation level.

Limited and early analytical results from integrated analyses of the global costs and benefits of mitigation indicate that these are broadly comparable in magnitude, but do not as yet permit an unambiguous determination of an emissions pathway or stabilisation level where benefits exceed costs.

The Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) shows that, for the stabilisation level outlined by RCEP, non-CO2 gases will increase the equivalent CO2 concentration in the atmosphere by approximately 100ppm.

The potential for further reductions in warming, both up to 2100 and beyond, through non-CO2 gases, depends on whether, in more comprehensive scenarios (when such become available), their stabilisation levels are less than the levels assumed here.
