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]

The Risk Of Spaceflight
A new paper assessing spaceflight mortality. Not sure how useful it is, given the admitted paucity of data.
[Update a few minutes later]
When a Mars simulation goes wrong. Yes, we have a lot to learn before we go to other planets, and even then, people will die, often in terrible ways. Part of the answer is that we have to be more ambitious about how many we send. Six simply isn’t enough.
Freeman Dyson
An interesting interview of one of the most fascinating men of the 20th century. I saw him at ISDC, and he is holding up well mentally, though he’s been physically frail for decades.
[Wednesday-afternoon update]
Well, the comments have certainly drifted on this one.
More Junk Nutrition “Science”
The “Mediterranean Diet” has been discredited.
The Climate Debate
Judith Curry lays out her luke-warmist case.
The Climate Wars
The (rare) voices of reason:
10. Can we put the polarization genie back in the bottle, on climate or anything else? I really don’t know. But I do wonder how those advocating further radicalization of climate advocacy imagine any of this ends.
11. Making ever more radical demands might be a fine strategy were there someone to negotiate with. But by the reckoning of most prominent climate hawks, there isn’t.
12. Nor does it appear that a more inclusive climate coalition is likely to bring larger congressional majorities. Any Democrat-only climate strategy has to be predicated on not only winning but holding purple/red districts over multiple elections.
13. These are precisely the districts that radicalized climate rhetoric alienates culturally and the green policy agenda punishes economically. Since the failure of cap and trade in 2010, climate activists have taken rhetoric to 11, and what it got them was Trump.
And it will continue to.
A To-Do List For Bridenstine
Some advice from Scott Hubbard. But here is the problem:
…the new administrator must provide NASA and the rest of the world much more clarity on the brief statement issued by Vice President Pence and the newly revived Space Council that the United States will “lead the return of humans to the Moon.” Studies of the future of human space exploration have for decades emphasized that Mars is the target of greatest interest for reasons of science and exploration.1–4 The last initiative that attempted to include both human landings on the Moon and eventually Mars, the so-called Constellation program, collapsed from its own budgetary (over) weight.
Two points: First, the assumption that human spaceflight is about “science and exploration.” I’ve written about this error at length. Second is the notion that Constellation collapsed because it was attempting to do both the Mars and moon. It wasn’t seriously trying to do either. NASA wasn’t seriously trying to do either.
Recycling
It’s always been a pointless scam, and it’s becoming ever more clear. As Glenn has noted, all the sorting and binning is mostly a religious ritual.
