Sentences with phrase «target cumulative carbon emission»

Rather than talking about a target concentration, they should be talking about a target cumulative carbon emission.

Not exact matches

By framing the issue in terms of a carbon budget based around cumulative emissions, the IPCC's most recent report showed that it doesn't necessarily matter what short - term emissions reduction targets are adopted, or which country cuts emissions by a particular amount relative to another nation's pledges.

A global warming target is converted to a fossil fuel emissions target with the help of global climate - carbon - cycle models, which reveal that eventual warming depends on cumulative carbon emissions, not on the temporal history of emissions [12].

But a carbon tax that increases over time at a persistent and predictable rate would minimize the expected economic cost of achieving any climate target (targets that depend, given the way the climate system works, on cumulative emissions over many decades).

Holding concentrations or temperature (more remotely) to a particular target therefore means limiting cumulative emissions of, say, carbon over time... a limited amount of time if we are talking about an iterative approach, and over a long period of time if we are talking about reducing the likelihood of some very nasty consequences well after we (but not our grandchildren — if we are lucky enough to have some) are gone.

This ends up changing estimates of cumulative carbon emissions since the pre-industrial period, but given the large uncertainties involved the authors caution against using these revisions to draw conclusions about remaining carbon budgets associated with staying within the 2C or 1.5 C warming targets.

This means that only two emission targets — the peak rate and cumulative carbon emissions — are needed to constrain two key indicators of CO2 - induced climate change (peak warming and peak warming rate), as evidenced by the maximum - likelihood estimation method used above.

Our findings relating to the rates of warming also show that only two emission targets (peak emission rate and cumulative carbon emissions to 2200) are needed to constrain two key indicators of CO2 - induced climate change: peak warming and maximum rate of warming.

But they have not been doing so at a rate consistent with keeping cumulative carbon emissions low enough to reliably stay below the international target of less than 2 degrees Centigrade of global warming.
