Climate Impact Lab’s Projections of US Future Temperature Maps
We present their graphs of the US future temperature maps for the average of June/July/August, under the “business as usual” or no climate mitigation scenario. This is called RCP 8.5, where in 2100, the average climate forcing of greenhouse gases and other anthropogenic causes is 8.5 W/m^2 above pre-industrial times. Currently, we are about 2 for this year. The previous projections which we presented were for an estimate of obeying the present initial Paris Agreement emissions, which would give us RCP 4.5 in 2100. These projections are from the Climate Impact Lab at impactlab.org
The first US map is for the preceding recent 30 year period 1981-2010.
The next is for the next twenty years, 2020-2039.
Then there is the Mid-Century twenty year period 2040-2059.
Finally, there is the twenty year end century period for 2080-2099.
We note that coastal areas, and particularly the West Coast, with its cloudy mornings June Gloom, are spared some of the the heating. The Northern states are mild, and the Rockies and Sierras are cooler, still. But, the snow occurring and holding seasons will shorten, and produce water shortages.
