There were other clear linkages to the ongoing UNFCCC negotiations in the discussions, for instance on: what period can be referred to as «pre-industrial,» how to describe the qualities of such metrics as Global Warming Potential and Global Temperature Potential, and how to address the implications of RCP scenarios in the context of staying below 2 °C of warming or a lower warming target.

It appears that Pruitt instructed the EPA career staff to make assumptions grossly unfavorable to the CPP in order to calculate the largest possible negative economic impact; for example, the RIA models scenarios that minimize the CPP's reductions in unhealthy air pollutants, inflate the costs of compliance, only count the climate benefits of CO2 reductions in the US, and greatly discount the future benefits of lower global temperatures.

The modeling results indicate that, if nations continue to increase their emissions of greenhouse gases in a «business as usual» scenario, the U.S. ratio of daily record high to record low temperatures would increase to about 20 - to - 1 by mid-century and 50 - to - 1 by 2100.

With respect to climate change, the lower scenarios where we might get «only» a 1.5 ° C temperature rise are still pretty scary.

By the year 2500, there are complete recoveries of the globally averaged surface air temperature for all versions of the GISS climate model in the low - forcing scenario RCP2.6.

He says low values of climate sensitivity will still affect global temperatures as CO2 concentrations in the atmosphere rise, but increases in temperature may be of similar magnitude to naturally driven temperature cycles, a scenario that has strong implications for how we manage causes and consequences of climate change.
