Epic take-down of Roger Pielke Jr's appallingly shoddy academic "work", which he's used--as an attack dog of the Koch Brothers-funded think tank AEI--to discredit the case for climate action:
In a 2024 paper criticizing the 'billion-dollar-disasters' database, Roger Pielke Jr. published analysis that is best described as a Russian-doll of errors.
Here's my in-depth take down of his appallingly bad work.

Roger Pielke Jr.’s Appallingly Bad Analysis of Billion Dollar Disasters – Economics from the Top Down
In a recent paper called Scientific integrity and U.S. “Billion Dollar Disasters”, Roger Pielke Jr. published a chart that's so bad I've devoted a whole essay to debunking it.

Remember the recent middle-of-the-night apartment building raid where children were dragged outside naked & zip-tied in the street while black & Latino residents were _sorted by race_ and piled into separate vans while their apartments were ransacked & robbed? That raid? So it resulted in 0 arrests.
Homeland Security Secretary Kristi Noem should resign and be criminally charged, according to critics who seized on a report revealing that zero people who were arrested in a high-profile raid were charged with a crime.

Alan Dershowitz is one of those claiming Epstein was not a pedophile because he pleaded guilty to one count of having sex for money with a 17-year-and-10-month-old person. "That’s not a pedophile." See this important response from Julia Brown, the brave reporter who broke the news on this

I know it’s too much to expect them to know their history, but if the American Revolution had a motto, it definitely would not have been “immigrants go home.”
It would have been “get your fucking soldiers out of our cities.”

I really, truly hope that over the next week the Dems get their shit together, all get on the same page, and just keep repeating that American families are starving to protect the Epstein client list. Over, and over, and over again. Every interview, every broadcast. Starving people to protect pedos.

What's "small" here is John Fetterman, a person so weak of mind and devoid of principles, so used to the lazy grift he switched to after winning office, that he won't even criticize corruption so brazen it has no parallel in American history, the President literally paying himself a fortune.
Fetterman describes Trump trying to steal $230 million from taxpayers as "small ball, and I think we have much bigger problems than worrying about those things."

Compare yesterday's millions to this and how we couldn't escape breathless coverage of the Tea Partiers at their peak.
![April 15, 2009 is said to have been the day that had the largest number of tea party demonstrations reportedly in more than 750 cities.[73] Estimates of protesters and locations varied. The Christian Science Monitor reported on the difficulties of calculating a cumulative turnout and said some estimates state that over half a million Americans participated in the protests, noting, "experts say the counting itself often becomes politicized as authorities, organizers, and attendees often come up with dramatically different counts."[74][75] Grover Norquist, president of Americans for Tax Reform, estimated that at least 268,000 attended in over 200 cities.[76] Statistician Nate Silver, manager of FiveThirtyEight.com, has said that a cumulative crowd size estimate from credible sources was of 311,460 attendees in 346 cities, which accounted for all capitols and major cities little noticeable or no reliable media coverage in other protests could have contributed to a lower number of attendees and locations.[77] The largest event, in Atlanta, drew between an estimated 7,000 to 15,000 protesters.[77][78][79] Some of the gatherings drew only dozens.[74]](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:kdphmaoqeaouax2kis27556e/bafkreieux2zxjfxl2vnbcgw6jxcqzzdqksj7oai2hsduocsjafcl5t67w4@jpeg)
