This is a very big deal

In an update to their investigative report House Foreign Affairs Committee Republicans have concluded that COVID-19 is the result of a lab leak by a “preponderance of the evidence”

Good thread on updated investigative report
Here is the hypothesis for origins put forward by the Rs of the HFAC
Here is the full hypothesis on origins -- worth your time
This is troubling
Daszak has refused to cooperate by answering questions
He may now get a subpoena
The conclusion
With a request for more evidence
Make no mistake, this report - coming from the US Congress - is a big deal

🧵New normalization paper

Franzke, C. L. (2021). Towards the development of economic damage functions for weather and climate extremes. Ecological Economics, 189, 107172.
doi.org/10.1016/j.ecol…

Comprehensively validates (again) the normalization literature

Short thread...
Economic damage from weather extremes has increased around the world as wealth & exposure have grown

But normalized for GDP, damage is down sharply

This is great news Image
This trend holds in Africa Image

I am starting to wonder if some professors in climate who are now regularly harassing me in absolutely over-the-line & nutso ways have serious drinking or mental health issues

Really strange behaviors
I can take the politics, name calling and anger - Fine

But repeatedly lying about me and making up stuff is way over the line

Its one thing when randos do it, but professors are held to a much higher standard
For now I'm not doing anything more than just blocking the offenders and hoping they get the help they need 🙏

There’s two big issues here
Our work focuses on one of them

1. Climate models (unconstrained by obs) are running too hot
2. Scenarios used to “drive” these models are out of date (too much CO2)

Our work focuses on 2

Together these have led to serious issues needing fixed
You can read about the issues with scenarios here, based on foundational work by @jritch & continuing collaborations with @matthewgburgess

Many others have done important work on these issues as well …

A short 🧵 on my Senate testimony earlier this week
With key highlights

You can find the full text here:
banking.senate.gov/imo/media/doc/…
My focus is on the provision of robust science advice to policy makers on climate & evidence that scientific integrity has suffered in key ways

But first, lest there be any confusion. . .

1⃣ Those who are familiar with my views will know the below Image
2⃣ Scientific integrity would seem to a a topic that both Democrats and Republicans should be able to agree on

The US government generally (but definitely not always!) does an excellent job in soliciting and securing robust expert advice

Climate should be no different Image

This is an interesting new paper
For heat outcomes, finds vulnerability reduction can be much more important than climate risk increase

Landreau et al 2021. Combining socio-economic & climate projections to assess heat risk. Climatic Change, 167(1), 1-20.
link.springer.com/article/10.100…
"The assessments of future climate risks are common; however, usually, they focus on climate projections without considering social changes"

True!

If you see a study with "no adaptation" used as a projection of the future, run away, fast!

This paper considers adaptation
How society develops will say more about how future heat risk evolves than will changing climate risk alone

The choices we make ... both emissions and societal will determine our collective future
