a) Our models can not explain the early 20th century warming period b) We know that the (statistically indistinguishable) late 20th century warming was caused principally by human - caused forcing.

Human - induced forcing exhibited a slow rise during the early part of the last century but then accelerated after 1960.2 Thus, these graphs highlight observed changes in climate during the period of rapid increase in human - caused forcing and also reveal how well climate models simulate these observed changes.

I had suggested that as an approximation that one could subtract the average increase from the earlier period which represents one expression of temperature increase caused by natural variation from the later period where the increase is augmented by Anthropogenic CO2 in order to get some idea of what one might attribute to natural variation and how much to CO2.

For this reason, a joint research project between Widener University Commonwealth Law School and the University of Auckland recommended in Paris that national climate commitments be stated in tons of emissions over a specific period rather than percent reductions by a given date because waiting to the end of specific period to achieve percent reductions will cause the total tons of ghg emitted to be higher than if reductions are made earlier.

Consider two emission pathways, both with a cumulative total of 1 TtC, but one with a decaying emissions floor, and one with no emissions floor: the pathway without an emissions floor will cause a temperature peak earlier than the pathway with the decaying floor, as the emissions floor causes emissions to be emitted over a longer time period.

IPCC has stated (AR4 WG1 Ch.9) that the «global mean warming observed since 1970 can only be reproduced when models are forced with combinations of external forcings that include anthropogenic forcings... Therefore modeling studies suggest that late 20th - century warming is much more likely to be anthropogenic than natural in origin...» whereas for the statistically indistinguishable early 20thC warming period «detection and attribution as well as modeling studies indicate more uncertainty regarding the causes of early 20th - century warming.»

Granted, the «great climate shift» of 76 - 77 occurred as well about this time, and many would say that warm period of the PDO is really the caused of the warming in the late 20th century, but it would be interesting to hear your rationale for choosing the early 1950's as the beginning of your measurement period for looking for anthropogenic effects, as from 1950 to about 1980, we have no need of an anthropogenic explanation, as the length of the solar cycle can fit the temperature curve quite well.

«The assessment is supported additionally by a complementary analysis in which the parameters of an Earth System Model of Intermediate Complexity (EMIC) were constrained using observations of near - surface temperature and ocean heat content, as well as prior information on the magnitudes of forcings, and which concluded that GHGs have caused 0.6 °C to 1.1 °C (5 to 95 % uncertainty) warming since the mid-20th century (Huber and Knutti, 2011); an analysis by Wigley and Santer (2013), who used an energy balance model and RF and climate sensitivity estimates from AR4, and they concluded that there was about a 93 % chance that GHGs caused a warming greater than observed over the 1950 — 2005 period; and earlier detection and attribution studies assessed in the AR4 (Hegerl et al., 2007b).»

And if CO2 causes rising temperatures, why did the huge increase of CO2 during the early Cretaceous period coincide with the huge drop in temps seen at the time?

You aren't thinking about the warming period early last century, because we know it was a relatively brief period, and so lacked huge significance, and was caused by a combination of CO2 emissions, high solar activity and low volcanic activity and the later two factors haven't been apparent since the 1970's modern warming period.

[65] Earlier still, a 200 - million year period of intermittent, widespread glaciation extending close to the equator (Snowball Earth) appears to have been ended suddenly, about 550 Ma, by a colossal volcanic outgassing that raised the CO2 concentration of the atmosphere abruptly to 12 %, about 350 times modern levels, causing extreme greenhouse conditions and carbonate deposition as limestone at the rate of about 1 mm per day.
