I’d like to say that this is amazing, but sadly, it isn’t.

Was it a mistake?
No; it enabled modern civilization, but it did so at a cost to human health. I haven’t read the whole thing yet, it’s long.

OK, I got all the way through it. She doesn’t really address the health effects of a grain-based diet.
Dinosaurs And Gravity
I saw an interesting postulation on Twitter that the reason the dinosaurs could grow so large was that there was less gravity during the Mesozoic. My response:
All I know is that, if earth’s gravity was really less for the dinosaurs, it’s one less excuse for them to have not had a space program that could have prevented them being wiped out.

The Hockey Stick Emails
An appeals court is compelling the University of Arizona to (finally) release them.
The sixth anniversary of the blog post that launched Michael Mann’s lawsuit against me and Mark Steyn is coming up next week.
Maximum Lifespan
We still don’t know the limit. As I often say, there is no law of physics that requires either senescence or mortality. Indefinite health and life is, in theory, a solvable problem.
[Afternoon update]
A commenter points out this recent article. Yes, I’ve discussed this with Gary, and it’s currently his focus, not space. Because none of us are getting any younger. BTW, the company name is pronounced “ocean,” I think. And yes, we should be trying to get Congress to tell the FDA to recognize aging as a disease to be treated, and not simply inevitable.
Harlan Ellison
RIP.
In addition to the books and short stories, he wrote some Twilight Zone episodes, and Star Trek.
I woke up from s nap and my wife told me we'd lost Harlan. I knew his writing forever, and knew him for over 30 years. I don't know that we were friends; he liked my stuff, but he always scared hell out of me. I know I'll miss him. The field, too. Our enfant terrible is gone. https://t.co/kDT1Abqb0N

JWST
We expected this yesterday, but here it is:
Following an Independent Review Board report on the James Webb Space Telescope project, NASA has announced a further delay to the telescope’s anticipated launch. Coming just three months after a year-long delay to 2020, NASA now says the telescope will not be ready to launch until 2021 at the earliest and that the project will breach its $8.8 billion USD cost cap.
The cited mismanagement at NG and NASA is just staggering. The new overrun is about the amount that it was supposed to cost, in total, originally. What a programmatic disaster.
I hereby rename JWST the Jeebus Wept Sunkcost Trap

Here’s the story from Jeff Foust.
[Update a while later]
This can never be allowed to happen again…. The good news is that it does not have to. On Orbit Assembly transcends the limitations around building a big telescope on the ground, shaking the hell out of it for 10 minutes, then deploying it autonomously without fail. https://t.co/lPmq4UgdVi

[Thursday-morning update]
Here‘s Marina Koren’s take:
A wiring error caused workers to apply too much voltage to the spacecraft’s pressure transducers, severely damaging them. And during an acoustics test, which examines whether hardware can survive the loud sounds of launch, the fasteners designed to hold the sun shield together came loose. The incident scattered 70 bolts, and engineers scrambled to find them. They’re still looking for a few. “We’re really close to finding every one of the pieces,” Zerbuchen said.
These three errors alone resulted in a schedule delay of about 1.5 years and $600 million, Young said.
I think that’s about Northrop Grumman’s annual net income. If I were NASA, I’d tell them that if they ever want another NASA contract, they’ll eat it themselves.

Alex Witze has more, over at Nature.
Complex Organic Chemistry
For people interested in non-terrestrial life, this should be a higher priority than Europa. It’s farther away, but a much more benign radiation environment.
On Boundary Conditions And Initial Values
An interesting paper at Judith Curry’s site (which is a go-to place for people following the climate follies).
Once again, for the record, I find literally incredible the notion that we have either the understanding of the physical interactions or the computer power to predict future climate with any useful confidence.
Equilibrium Climate Sensitivity
If this new paper is correct, we should be firing up our SUVs.
[Friday update]
Thirty years on, how do climate predictions hold up?
Not well. [paywall]
