However, at the

Narrowly scoped, the present situation is either strictly caused
by solar variations (in which case I believe the «solar variation» crowd will inappropriately gain credibility over the next 10 to 20 years as we work through the next below
average solar cycle or two), or strictly caused
by CO2 concentrations (in which case I believe the «CO2 concentrations» crowd will inappropriately lose credibility as the non-linear relationship (sensitivity is based on doublings, not linear
increases) between
increased CO2 concentrations, and forecasts for below
average solar cycles reduces the longer term upward trend in
global temperatures).

Finally, to revisit the question originally posed @ 203: Assuming the IEO2011 Reference case of «1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035», and given that this case equates to following RCP8.5 until 2035 as previously demonstrated @ 408, what

Aware of the broad scientific view that the
increase in
global average temperature above pre-industrial levels ought not to exceed 2 degrees C, we support an aspirational

global emissions
by 50 percent
by 2050, with developed countries reducing emissions
by at least 80 percent
by 2050, and recognizing the critical importance of development, including poverty eradication, in developing countries.
A recent video of him being interviewed
by Brit Hume of Fox News had Michaels asserting that while
global warming was real we could expect the
average rate of
temperature increase over the last century to remain flat over the next century, and so no big deal.
The real forecast is 383 ppm rising at 2 ppm / year, a minimum carbon dioxide sensitivity to doubling of 3 C, adding positive feedbacks, some of which are unknown, yields a 5 C
increase in
global average temperatures by 2100, and of course, time does not stop in 2100.
