No cites? Just more hateful scorn heaped on real scientists? It's like you're stuck in the dark ages, mhaze. Now, that's quite telling indeed.
Run along. The adults are going to talk now.
Well, again, considering that the paper isn't available yet, I imagine they would have the same initial criticisms:
-comparing global radiation data to ocean temperatures only
-seven years of data...
- I imagine they would also comment on the implications of his climate sensitivity estimate. Can you get a realistic cycle of glacial-interglacials with such a low sensitivity?
-he ignores temperature data below 0.03°C
-and like I said, he calls this robust. This doesn't fit any form of the definition for robust that I've ever seen used by scientists.
Agreed. "Robust" has been misused enough including by Mann et al to make it a word to be avoided.
Regarding the glacial-interglacial issue, those always start with some premises and then lead to conclusions. The premises thus can be chosen such that the conclusion nets out similar to what's "desired". Put it another way, I'm suspicious of any "proof or rebuttal" about current day events that has to go back to utter guess work concerning the historical past for support. Well, unless a scientific proof can be based on a guess...
Regarding the need or utility for a longer time series and more data points, consider the following.
Suppose you had
a full 30 year cycle (eg 30 years for ocean AMO and PDO effects). Is there some sense in which say the warming side of the PDO cycle would reverse the feedbacks found by Spencer? Spencer looked at short term stronger effects,
irregardless of sign. I can't see that. Maybe someone else can produce an argument in that direction.
Side note:
It occurs to me that Tsonis 2007 in his work "Heat Capacity" used a similar technique of moving time sliced windows across the entire time domain, and comparing the correlation of the data within each of those times slices with the baseline. This was in reflation to calculating ocean heat. Obviously, some offsets (in time phase shift) would show improved correlation over others.
Tsonis showed most variation in global temperature to be the product of aligning or separation of the effects of four major ocean cyclic systems plus a background "secular trend". That background trend is quite small (I'll return to this shortly).
Because major variations could be mathematically modeled in this method (and predicted) Tsonis suggested that there was no reason for the "post 1950s temperature rise" to be considered as due to greenhouse gases, and there to be no reason to consider the 1950-1970 cool period to be due to some kind of offsetting effect by aerosol cooling.
Notice this flies in the face of one line of argument which goes "Solar didn't increase after 1950 but temperature did, so the temperature increase must be due to Co2, because there is nothing else that could have caused it". This argument is actually based on aligning and correlating data in the immediate: 1995 temperature, 1995 solar. Tsonis got his interesting results by looking at phase offsets with four separate but coexistent ocean cycles. So yes, there are other things that could have caused the "post 1950 temperature increase" in large part.
That background "secular trend" of Tsonis is quite in line with the small effect of greenhouse gas forcing which Spencer calculates.
