Sentences with phrase «global emissions reductions pathways»

Yet understanding how delay makes achieving the goals of preventing dangerous climate change extraordinarily more challenging also requires some knowledge about how increasing atmospheric concentrations affect global emissions reductions pathways options.

And we do so (see the Appendix) for a global emergency emissions reduction pathway that is stringent enough to provide a high probability of holding the 2ºC line.

This discussion has so far focused on global emissions - reduction pathways, but global pathways can only tell us so much.

However, a clear understanding of how national emissions reductions commitments affect global climate change impacts requires an understanding of complex relationships between atmospheric ghg concentrations, likely global temperature changes in response to ghg atmospheric concentrations, rates of ghg emissions reductions over time and all of this requires making assumptions about how much CO2 from emissions will remain in the atmosphere, how sensitive the global climate change is to atmospheric ghg concentrations, and when the international community begins to get on a serious emissions reduction pathway guided by equity considerations.

Scenario analysis on the implications of changing emission tracks after 2020, from an insufficient global deal on 2020 reductions, to 2 °C and 1.5 °C pathways

IEA analysis shows that on a 2 degree climate pathway, energy efficiency contributes nearly 40 % of global emissions reductions through 2050, the largest share of any fuel.

The Swiss climate plan is in many ways a promising start to the global INDC submission process, articulating a long - term pathway for the country's emissions reductions.

No US national climate change strategy makes any sense unless it is understood to implicitly be a position on the US fair share of a global greenhouse gas emissions reductions pathway capable of preventing dangerous climate change.

The following is one depiction of a carbon budget prepared by the Global Commons Institute with three different reductions pathways that make different assumptions about when global ghg emissionsGlobal Commons Institute with three different reductions pathways that make different assumptions about when global ghg emissionsglobal ghg emissions peak.

The lack of a «conceivable pathway to reducing CO2 concentrations... on the timescales put forth by the Paris Agreement» is not improved by said Agreement's permitting «developing countries» (responsible for about 65 % of global emissions) to prioritise «economic... development and poverty eradication» over CO2 reduction, merely encouraging them to «move over time towards... emission reduction or limitation targets»: https://judithcurry.com/2016/08/16/cop21-developing-countries/

AR5 found the world has the means to limit global warming and build a more prosperous and sustainable future, but pathways to limit warming to 2ºC relative to pre-industrial levels would require substantial emissions reductions over the next few decades.

Multi-gas Emissions Pathways to Meet Climate Targets, Climatic Change 75 (1): 151 - 194, estimates that this would require global emission reductions of over 5 % per year, unless more CO2 was removed from the atmosphere later.

Any carbon reduction pathway that limits temperature rise to 2 degrees C shows global emissions peaking extremely soon and declining extremely quickly.
