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:

A new paper assessing spaceflight mortality. Not sure how useful it is, given the admitted paucity of data.

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.

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.
