“counter-opinion masquerading as fact checking”

Very good look at “fact checking” by @JohnTierneyNYC
I documented the clear use of flawed information by “Climate Feedback” to censor views apparently accurate but I welcomed
⤵️
MIT’s Emanuel has a fine academic record but he also states that his extreme views on disaster contradict the IPCC consensus

By selecting him as a “fact checker” to censor others, Facebook is able to stealthily counter the IPCC consensus while still invoking “facts”

Clever!
Emanuel is a regular go-to by reporters to counter IPCC - not directly but by countering those who invoke the IPCC consensus on extreme weather and disasters

Emanuel was called in to justify removing me at 538 in 2014 & more recently is used to bludgeon @ShellenbergerMD

Facts!
If you ever wonder why my research on hurricanes & disasters is never mentioned in the major media despite being widely cited & in IPCC, it’s very good science but very bad “facts”
No reporter wants to risk being “fact checked” by citing these bad facts🤷‍♂️

tandfonline.com/doi/full/10.10…
MIT's Emanuel has effectively monetize RCP8.5 by selling hurricane projections to gov't & industry (including fossil fuel)

I wouldn't deny anyone the chance to make a buck off their expertise, but these bucks should be relevant when appointing "independent fact checkers"😎
I was once a co-collaborator with Emanuel (& R. Mendelsohn) on a World Bank project on hurricane risk (L)

I resigned from the project when I learned how much $👀 Emanuel was being paid by the WB to produce "synthetic hurricane tracks" (R)

Emanuel has been after me ever since
Emanuel uses RCP8.5 in extreme projections at odds with IPCC & uses those pubs to recruit clients for his business selling "synthetic hurricane tracks" from these papers
He uses his "fact checking" platform against anyone who openly expresses a more mainstream view of hurricanes
Don't take it from me, Emanuel associates (below) almost all of his publications since ~2006 to the marriage of his research & his business
windrisktech.com/publications.h…
So when Emanuel was writing in 2014 to undercut my peer-reviewed research on hurricanes & disasters, you may have thought he was making a set of scientific arguments. Maybe so, but he was also writing to preserve a business model, a very lucrative one
Emanuel has parlayed his standing into a prominantrole as "fact checking" gatekeeper at Climate Feedback, where he routinely attacks anyone who cites IPCC consensus on extreme events here are two false claims from Emanuel just this month . . .
First
In a "fact check" of a new book by Steven Koonin Emanuel cites a recent PNAS paper (L) but fails to reveal that that paper was followed by a major correction (R) that undercut the findings Emanuel is citing

Fact check fail
Second
Emanuel says "no one familiar with the global record of tropical cyclones would look at data prior to 1980"
There is plenty of data worth looking at

Just to cite one example, we've published global data on TC landfalls from 1970
journals.ametsoc.org/view/journals/…

Fact check fail
Kerry's a nice guy
He also is massively conflicted in his dual roles as a highly successful RCP8.5 salesman & powerful "independent fact checker" of RCP8.5-based claims

And Kerry is not unique in this
It persists because other than right here, you'd never know about it

🧵The US National Climate Assessment has been a politiczed mess from the start due to its institutional design, which places it in the White House

The NCA proved too tempting for both Ds and Rs to put a thumb on the scale

Links at end of thread . . .
The idea it was perfect under Democrats, as @afreedma & other advocacy journos suggest, is simply wrong

The most recent NCA was totally capture by interest groups and companies that would benefit from the report - UCS, TNC, EDF, CAP, Stripe etc

Below just a few of its authors Image
@afreedma The head of the NCA5 stated publicly that she would never cite our work in the assessment, even though our work is by far the most cited research on economic losses in the US associated with floods, hurricanes, tornadoes

Here is how the NCA handled a reviewer comment Image

🧵Let's take a quick look at the implications of the regulations that have followed from the 2009 EPA endangerment finding

According to @C2ES_org the 2021 GHG standards for light vehicles would reduce projected CO2 emissions by a cumulative 3.1 billion tons to 2050
c2es.org/content/regula…Image
Over the next 25 years the world would emit 925 gigatons of CO2 assuming constant 2025 emissions and ~690Gt assuming emissions are cut in half by 2050

That means that the projected impact of the regulations would reduce global emissions by 0.0003% (constant) & 0.0004% (halved)
The idea that CO2 can be regulated out of the economy is flawed

If the purpose of CO2 regulation is to create a shadow carbon tax, then it is a horribly inefficent way to do that

Once again, all this leads us back to Congress and the need for smart energy & climate policy

🧵
The percentage of a percentage trick is increasingly common & leads to massive confusion

Here a undetectable difference of 0.01 events per year per decade is presented as the difference between a 31% and 66.4% increase (in the *likelihood* of the event, not the event itself) Image
The resulting confusion is perfectly predictable

Here is a reporter (NPR) explaining completely incorrectly:
"The phenomenon has grown up to 66% since the mid-20th century"

False Image
Also, the numbers in the text and figure do not appear to match up
I asked Swain about this over at BlooSkeye Image

The new hurricane damage time series trick

Step 1: create Frankenstein dataset w/ an increasing trend where there was not an increasing trend before

Step 2: Attribute the increasing trend to climate change

Step 3: Use Frankenstein dataset to impeach other research w/ no trend Image
The reason that the blue and red numbers are different is that they are different measures of hurricane losses

E.g., the red numbers include inland NFIP damage
The blue numbers do not, on purpose, because NFIP only started in 1968

They are apples and oranges
Now 3 peer-reviewed papers (PNAS, JAMC, BAMS) make this most basic of errors by replacing and splicing NOAA BDD to the MWR/NHC time series

Predictably all three papers find an increasing trend in normalized hurricane damage even though landfalling hurricanes are not increasing Image

A Frankenstein dataset results from splicing together two time series found online

Below is an example for US hurricane damage 1900-2017
Data for 1980-2017 was replaced with a different time series in the green box
Upwards trend results (red ---)

Claim: Due to climate change! Image
The errors here are so obvious and consequential that it is baffling that the community does not quickly correct course

Read about it here
Is my analysis flawed?

The IPCC AR6 cited a paper misusing the Frankenstein hurricane loss dataset to suggest that NOAA's gold standard hurricane "best track" dataset may be flawed

JFC - Using flawed economic loss data to suggest that direct measurements of hurricanes are in error! Image

We’ve reached the point where an IPCC author is openly rejecting the conclusions of the IPCC out of concern over how their political opposition is correctly interpreting the AR6

The integrity of the IPCC on extreme events is now under attack
The IPCC explains that a trend in a particular variable is DETECTED if it is outside internal variability and judged with >90% likelihood

For most (not all) metrics of extreme weather detection has not been achieved

That’s not me saying that, but IPCC AR6 Image
The IPCC also assesses that for most (but not all) metrics of extreme weather the signal of a change in climate will not emerge from internal variability with high confidence (ie, >90%) by 2050 or 2100, even assuming the most extreme changes under RCP8.5 Image
