So for those periods that you think may have been warmer — say the 1640s or the first part of the 1500s, do you have any theories about the natural phenomena that would be explanatory?

Indeed, in your first example you conflate the two types of question, starting with a hypothesis «most of the observed warming is anthropogenic» and concluding with an estimate of proportion «My assignment allows the anthropogenic influence to be as large as 70 % and as small as 30 %, leaving plenty of room for natural variability and uncertainties.»

If you are going to look to natural factors you realize that global warming fearmongers are «spitting in the wind,» as in, «You can go outside and spit and have the same effect as doubling carbon dioxide,» and, «If the atmosphere was a 100 - story building, our anthropogenic CO2 contribution today would be equivalent to the linoleum on the first floor,» as follows:

Since 1680 was long before co2 began increasing and also well before the industrial revolution, and — it would have taken considerable additional time for the low annual increase in co2, when it did finally begin, to have an impact on temperature, it's safe to state that the first 200 years of warming were merely natural climate variation.

They have long appreciated - ever since the early 1990s, when the global warming bandwagon first started to roll behind the gravy train of the UN Inter-governmental Panel on Climate Change (IPCC)- that such short - term climate fluctuations are chiefly of natural origin.

If the real optimum p.CO2 — for photosynthesis — GPP — is higher than at present, this addition — as a result of warming — for example, the first 5 ppmv CO2 (natural) will have a different effect than the next 5 ppmv CO2 (if we assume an exponential increase in the efficiency of photosynthesis — GPP).

An analysis of the historical data suggests a strong correlation between the solar activity and the natural climate variations on centennial time - scales, such as the colder climate during the Maunder (about 1650 − 1700 AD) and Dalton (about 1800 − 1820 AD) minima as well as climate warming during the steady increase in solar activity in the first half of the twentieth - century (Siscoe 1978; Hoyt & Schatten 1997; Solomon et al. 2007; Gray et al. 2010).
