Deposition in Mann vs. CEI/National Review rogerpielkejr.com/2021/05/15/dep…
In it I discuss Climategate, The Hockey Stick, Grijalva, 538, IPCC, Mann's years of attacks on me and others & the differences between fraud as a catch-all colloquialism and the formal definition of research misconduct in science . . .
An excerpt . . .
I'm on record defending Mann against inquiries by Congress and Commonwealth of Virginia

I'm also on record about the ridiculousness of his various lawsuits -- and scientists going to the courts in general

It is inside baseball⚾️
But who know will know

For those following interminable saga of Mann v CEI
Some remarkable new documents online
1-Oreskes deposition: dropbox.com/s/xwn9vv8qbrhs…
2-Steyn memo: steynonline.com/documents/1111…
3- Steyn uncontested facts: steynonline.com/documents/1097…
Oreskes provides an incredible look at the intolerance expressed towards anyone with a divergent view to Mann

It also give a disturbing peek at the array of people and organizations working behind the scene to delegitmize those with such views

UCS was running PR for Mann
These are incredible passages from the Steyn docs
They jibe with my personal experience ImageImage

Pennsylvania state climate assessment just published
Relies centrally on RCP8.5 as BAU
Prepared by yet another "climate consultancy" that trades in RCP8.5 analyses

The PA report also confuses growth in wealth with climate trends, using the widely misused "billion dollar disaster" metric of @NOAA
I have no idea how much public money across the US is being spend on "climate consultants" to produce dodgy reports based on RCP8.5 and billion$ disasters, but it has to be an awful lot ... It's like spending public health money on homeopathy instead of vaccines

“A new 46-person federal scientific integrity task force with members from more than two dozen government agencies will meet for the first time on Friday. Its mission is to look back through 2009 for areas where partisanship interfered with...”

The idea presented in this piece that the politicization of science by presidents started with Ronald Reagan is laughable

Here is an Eisenhower anecdote from our science advisors project

The politicization of science in the White House has deep roots

Siri, what is “irony”?

President Biden’s OSTP political appointees just reassigned the climate scientist leading the US National Climate Assessment in order to present a “less nuanced” view of climate change Image

This is an incredible story of science gone wrong

Does ocean acidification alter fish behavior? Fraud allegations create a sea of doubt sciencemag.org/news/2021/05/d…
This remarkable passage quoting an IPCC co-chair reveals a major pathology in climate science ... critique is not welcomed
Some of the language in the (overall excellent) Science article is interesting

A critique of published work is not an “attack” — it is science working exactly as it should

Who cares if the scientists are “young”?
How tall are they? What kind of shoes do they wear?

A short 🧵 on uncontrolled orbital debris re-entry . . .

Heads Up! A Used Chinese Rocket Is Tumbling Back to Earth This Weekend. nytimes.com/2021/05/06/sci…
Back in 2001 I led a NASA workshop on the risks and benefits of (a) a controlled re-entry of the TRMM (precipitation measurement) satellite vs (b) extending the mission, collecting more data and having the satellite re-enter in uncontrolled fashion
sciencepolicy.colorado.edu/about_us/meet_…
At our workshop NASA estimated risk of injury of uncontrolled re-entry to be ~2 in 10,000 (0.021%) w/ significant uncertainties

This was based on a 35 deg orbital inclination, estimates of the debris field and estimated 2004 global population densities

Daily dose of RCP8.5

Apocalypse porn (L) axios.com/antarctica-ice…

New Paper (R) nature.com/articles/s4158…

Of course, NDCs as BAU do not remotely equal RCP8.5 ImageImage
This is pretty poor and I'm surprised it wasn't caught in review

"a +3C scenario representing current policies" is being used here as a euphemism for RCP8.5-as-BAU

By "+3C scenario" it simply means that the scenario passes through +3C on its way to 8C in 2500

LOL
Clever ImageImage
In 2500 RCP8.5 is actually RCP12.0
