Thanks
Yes, go and watch 👍🤓

Rather than respond substantively, I see fellow academics calling for firing people. That's the wrong response, prudentially and morally.

YouTube video by Cornell Atkinson Center for Sustainability What Climate Science Actually Says About Extreme Weather

Here is my talk at Cornell that a few climate scientists are freaking out over and don’t want you to see

It gets nuttier

Cornell professor wants a faculty colleague fired for inviting me to lecture at Cornell 🤡

Remember when these guys ran climate science? Good times

Glad they are over 🤓

Former UVA president Jim Ryan, who resigned over the summer due to pressure from the Trump Administration, just shared this 12-page letter with the Faculty Senate, detailing his experience with the Board of Visitors and DOJ.

It's a surreal--and troubling--read.

"Projected future carbon-dioxide emissions from fossil-fuel combustion have been consistently revised downward... so climate campaigners have shifted the goalposts by lowering the threshold of what they promote as apocalyptic." by @thehonestbroker.bsky.social www.realclearscience.com/2025/11/12/c...

November 11th, 1940:
An Armistice Day storm raged across the Great Lakes Region and the Upper Midwest. A blizzard left 49 dead in Minnesota, and gales on Lake Michigan caused shipwrecks, resulting in another 59 deaths. Up to 17" of snow fell in Iowa.

When Less Warming Means More Fear As projected emissions fall, achievements once seen as climate progress are now being recast as signs of impending catastrophe

The chart most certainly visualizes the range of AI predictions accurately.

Bill Gates simply said the quiet climate truths out loud. "While the longer term implications of his letter are uncertain, early signs are that Gates has injected a welcome dose of climate realism into the discussion." by @thehonestbroker.bsky.social www.realclearscience.com/2025/11/06/b...

The Global Population Crisis that Never Was Apocalyptic visions of over-population have always been grounded more in politics than science

FIFA awarding a "peace prize" to Trump would be so absolutely on-brand, a truly genius innovation.

🇨🇦 Word count in the Canadian federal budget:

Crude: 4
Oil sands: 3
Oil and gas: 14
Pipeline: 5 (none of which are about actual pipelines)
Tanker: 0

LNG: 17
Natural gas: 14

Carbon: 94
Emission: 64

Damn
I’ve been checkmated 😎

Oh my

Again false

Let’s say you have a tabulation that you say represents global average temperatures

I plot the data to have a look and it looks like the below

Just by looking at the plot we can conclude that the data cannot be used to say anything about the real world

You are a researcher?! 🤷‍♂️

Scientific integrity and U.S. “Billion Dollar Disasters” - npj Natural Hazards npj Natural Hazards - Scientific integrity and U.S. “Billion Dollar Disasters”

False
I argue that the BDD tabulation cannot be used in research to say anything about the real world

Bill Gates Shakes Up the Climate Discussion It is not just his three truths, but the fact that he said them out loud

Grievance anchoring.

Person A wronged me in the past.
Person A now claims X.
∴ X is false.

Of course, and I was pleased to have the opportunity to reinforce Gates' 3 truths as well as this statement of his:

Gates includes what might have been a fourth truth... “Climate change is a very important problem. It needs to be solved, along with other problems like malaria and malnutrition.”

Thanks for coming clean

I didn’t think you had any concerns with my work

And yes — lifeboat ethics is deeply racist, whether from Hardin or from you 😎

Check out THB shortly 👍

I’ll make it easy for you
Here you go

You’ve written countless words and mean Tweets about me but oddly, have never once engaged any of my work🤷‍♂️

If it’s personal, just say so
No need to pretend it is about science
👍🤓🙏

You pivoted quickly away from the critique of my Nature paper after I pointed out its obvious fatal flaw

While I understand that you’d like to make this personal, I won’t take the bait

Do you have any substantive critiques of my work? Anything at all?

Or is it just purely a personal beef?

Wrong again
I’ve never changed my handle here at BSky

Why you would want to block people who you routinely follow and comment on is strange

But block away if that’s your thing 😎
