Like other such articles, one should not view it as an authoritative
source, but as an analytical sandbox.
E.g., much is said about a discrepancy between former CO2 levels in the atmosphere and how they do not correlate well with rises in temperature. We're talking about going back entire geological epochs.
Given this, one might reasonably ask: by what method(s) can today's researchers determine global temperatures 30 million years ago? By what methods might they determine atmospheric CO2 levels?
Now, it's conceivable that CO2 levels *might* leave physical evidence in
the composition of certain sedimentary materials, but *temperatures*? I
could see *relative* temperature in a gross way--inferring it from plant types and growth (but again: how *certain* can we be about the way
plants 30 million years ago actually worked, how they photosynthesized
in any deep understanding?) but I can't see how any level of granular, indexed measurement can be achieved.
And this says nothing about the levels of other greenhouse gases at the
time, nor about cloud cover, etc.
Nor about acyclical solar activity.
There are lots of other things to consider.
One easy one to check is if
modeling done in the 1990s that shows what global temperatures were to
be in 2020 differs from what was actually measured.
There's a chart in
he article that shows that it does not,
but the chart needs to be
checked close, and its sources; perhaps t is correct--who knows at this point?
The entire issue of climate change is so fraught with unwarranted
assumptions

The entire issue of climate change is so fraught with unwarranted assumptions and moving variables that very much consideration is
required before one can even hope to get a partial picture.
Much of life is like this: not very clearly demarcated. You have to
resist reflexive and polemic positions based upon what purport to be authoritative sources.

The entire issue of climate change is so fraught with unwarranted assumptionsWHat is the exact problem you have? You seem to have the same list of quibbles in each of your posts on the topic. Go systematically down that list and check what is written about each grievance. One by one.
That'll clear your head.

sounds like Pelle is scared to test his old climate computer models, now why would that be?Why would we have to go back 30M years to determine this?
