In the NYT David Keith takes on the IPCC, FCCC & makes the case that carbon removal or (his preference) geoengineering be deployed to cool the climate beyond a 2 or 1.5 C deg temperature target nytimes.com/2021/10/01/opi…
The IPCC AR6 weighted in on geoengineering, finding that it would lead to "substantial residual and overcompensating climate change" & we have "low confidence in our understanding"
The idea that it should be central to climate policy is a fringe view
If the goal of the FCCC in international climate policy is to hold GAST to <2 deg C (or 1.5 deg C) - demarcating "dangerous anthropogenic interference" - then contrary to Keith's claims, achieving net-zero CO2 meets that goal ... so says IPCC
Keith claims he could be financially impacted if geoengineering were to receive more attention & research funding
Unacknowledged: Keith is one of the most prominent & well-funded geoengineering advocates who stands to benefit the most from an increased focus on geoengineering
Skepticism of the IPCC now appears to be in vogue
But this skepticism comes from a different direction than it used to
Geoengineering is dangerous (see The Climate Fix)
IPCC has it right
Fringe views are sometimes interesting to hear but risk being taken seriously
Fun times 🤓

The new UK Sports Councils report is a nice ink blot for passionate advocates on the far sides of the debate (ie, the blanket exclusion vs blanket inclusion folks), but it mostly just restates where the issue is currently at
Reports @seaningle
"The long-awaited report argues there is no magic solution which balances the inclusion of trans women in female sport while guaranteeing competitive fairness & safety"
Of course
There is no "magic solution" in Paralympic classification either, but we do it
"Although the 2020 and 2021 hurricane seasons seem exceptional in our lifetimes and models portend an ominous future, researchers cannot attribute the increased activity to climate change yet" washingtonpost.com/weather/2021/0…
The evolving science of hurricanes & climate change defies efforts to create simple narratives
That is OK
It is complicated, characterized by a background of large variability on all time scales & lots remain unknown (and maybe unknowable)
Sometimes certainty isn't possible
Many don't realize if we can detect/attribute TC behavior to human forcing in 2021, that means climate models are badly wrong
