The extreme warming scenarios are driven by a CO2 feedback term in the climate models.
The social cost of carbon is the discounted monetary value of future climate change damages due to additional CO2 emissions (for example, the costs of adverse agricultural effects, protecting against rising sea levels, health impacts, species loss, risks of
extreme warming scenarios, and so on).
Our method allows us to calculate a very
extreme warming scenario.

extreme warm 2013 summer since the early 1950s, and project that similarly hot summers will become even more frequent in the future, with fully 50 % of summers being hotter than the 2013 summer in two decades even under the moderate RCP4.5 emissions
scenario.
The impact of these fluxes on the AMOC was generally small compared to the effect of enhanced poleward atmospheric moisture transport and ocean surface
warming; or it was only noticeable in the most
extreme scenarios.

extremes under two future
warming scenarios — RCP2.6 and RCP8.5 — throughout the 21st century.
The blanket - exemption treatment is based on increasingly questionable assertions that wind turbines reduce atmospheric carbon dioxide levels that supposedly cause global
warming, climate change,
extreme weather events and an amazing number of dog, people, Italian pasta, prostitution and other exaggerated or imaginary problems, plus others that exist only in computer models whose forecasts and
scenarios bear no resemblance to Real World conditions or events.

warming, so even the low amount of
warming since 1998 doesn't invalidate any
extreme scenarios.
I concluded that the projections of
extreme sea level rise are not consistent with plausible physical mechanisms, not supported by the available data, and further, that the AR4 projected range (about 30 - 50 cm by 2100) agreed perfectly with my projections over a wide range of
warming scenarios.
