Now maybe you have an explanation as to how how the planet can recover from a LIA and not warm up? Logically the planet has been warming, but that doesn't mean it is still warming. A least mean square regression of the data from 2000 to 2010 shows that there has been a slight overall cooling, despite the El-Nino driven high for 2010. Even Phil Jones from UEA has acknowledged that.
Do you have a source for this claim? If you said that "Most, not all believe a cause to be CO2 emissions" then I would agree entirely. The effect is calculable and beyond dispute. there is disagreement about the amount of the CO2 increase that is anthropogenic, and the amount that is natural.
Maybe you should review Monkton again. The majority of his data is from peer reviewed and published sources. A further large part is from the IPCC itself, and the very small remainder is referenced so the reader can repeat the research.
Again, do you have a source for this claim? As before, most agree that CO2 is a contributer, but all efforts to place numbers in one camp or the other have failed (from both sides of the argument). The reason why attempts to lable scientists in one camp or the other is because science doesn't work that way. Scientists look at what they know, and ask about the things they don't know. eg, there is dispute about the value of feed backs on the forcing. IPCC put forward the figure of +2.7. Sure enough if a feedback of +2.7 is applied to the forcing from change in CO2 concentration then that neatly explains the temperature rise from 1979 to 1998. It doesn't explain the failure to increase since then, nor is there any allowance for any other forcing. If that same +2.7 is applied to the 0.3% increase in TSI then that neatly explains the temperature rise from 1979 to 1998, and it explains the failure to increase since then, but there isn't any allowance for any other forcing.
So I'm of the camp the feedback value is much lower, and probably less than unity. Some even go so far as to claim a negative feedback. But if that is the case the data doen't yet add up.
Unfortuantely, some in the climate science communtity have presented computer model outputs as if it is actual data. Media then pick up on this and make claims such as the "The earth may have warmed 0.7 C since 1979." If they actually read the research they would find error bars and other statements that plea for caution.
And this is one of the natural drivers that further complicate the issue. But this methane release isn't new. I learnt about it in primary school in the early 1960s where we saw a movie of scientists burning the gasses given off through the tundra in Siberia.
