It reproduced a preliminary graph from a non-physical sciences group showing lower than
scientific consensus estimates for temperature increase through 2100 and conflated it with an entirely Economist - manufactured news item erroneously stating scientists are finding climate sensitivity is lower than previously expected (Hint: it's not).
Not exact matches
(such version is able to claim being
scientific, even while contradicting rather moderate warming
estimates based on IPCC
consensus)
We show how the maintained
consensus about the quantitative
estimate of a central
scientific concept in the anthropogenic climate - change field — namely, climate sensitivity — operates as an «anchoring device» in «science for policy».

Other ways that the standard or «
consensus» calculations bias the climate sensitivity upward also exist and are also not negligible (or at least there is no
scientific case that they are negligible), but for now it is sufficient to think about, and try to
estimate, the magnitude of the increase in H2O and latent heat flow from surface to upper troposphere.
No @RichardTol, a survey of vocal opponents of the mainstream is not a valid
estimate of
scientific consensus https://t.co/G8b2oK6Ojw (1/2)
Over recent years, various organizations have set out to
estimate just how widespread the supposed «
scientific consensus» on AGW actually is.
On average, being in one of the treatment groups (vs. the control group) significantly increases respondents»
estimate of the
scientific consensus (by 12.80 %).
Subjects were asked to provide an
estimate (0 % — 100 %) of the perceived level of
scientific consensus on human - caused climate change at both the beginning (pre-test) and at the end of the survey (post-test).
Moreover, a change in a respondent's
estimate of the
scientific consensus significantly influences the belief that climate change is happening, human - caused, and the extent to which they worry about the issue (note that belief in climate change and human causation also directly influence level of «worry»).
Last summer, climate communication researchers at George Mason University and Yale University published a commentary urging the science community to reiterate the
scientific consensus on climate change — that 97 percent of scientists support the conclusion that climate change is real, and humans are causing it — citing studies showing that exposing individuals to this message can increase their
estimates of the
scientific consensus by 10 to 20 percent.
The only thing I find noteworthy is that it further reinforces the point that there is no
scientific consensus on a best
estimate for equilibrium climate sensitivity, which is entirely in agreement with the IPCC's statement in AR5 WG1 SPM: «No best
estimate for equilibrium climate sensitivity can now be given because of a lack of agreement on values across assessed lines of evidence and studies.»
I doubt you realize it, but the «
consensus» mean has been falling and if it weren't for
scientific inertia would be back to the no feedback initial
estimate.
RE: 4th Error -RCB- Poses an objection to the non-
scientific term catastrophic [NOTE:
Scientific «
consensus» is often being used & / or implied in standard climate - change discourse - Yet
Consensus is a Political Term - NOT a
Scientific Term]- HOWEVER - When Jim Hansen, the IPCC & Al Gore, et - al - go from predicting 450 — 500 ppm CO2 to 800 — 1000ppm by the end of the 21st century -LCB- said to the be highest atmospheric CO2 content in 20 — 30 Million YRS -RCB-; — &
estimates for aver global temps by 21st century's end go from 2 * C to 6 * C to 10 * C; — & increased sea level
estimates go from 10 - 20 cm to 50 - 60 cm to 1M — 2M -LCB- which would totally submerge the Maldives & partially so Bangladesh -RCB-; — predictions of the total melting of the Himalayan Ice caps by 2050, near total melting of Greenland's ice sheet & partial melting of Antarctica's ice sheet before the 21st century's end; — massive crop failures; — more intense & frequent hurricane -LCB- ala Katrina -RCB- for much longer seasonal durations, etc, etc, etc... — IMO That's Sounds pretty damned CATASTROPHIC to ME!
After showing the misinformation, I asked people to
estimate the
scientific consensus on human - caused global warming, in order to measure any effect.
