Does Greta Thunberg’s Lifestyle Equal Climate Denial? One Climate Scientist Seems To Suggest So.
The climate debate has taken a nasty turn. It is no longer a shouting match between climate affirmers and climate deniers. Now the finger-wagging is taking place among climate affirmers on the subject of personal responsibility for combating...

New blog post (and paper in Coral Reefs):
"Who is controlling who? The curious case of the algae and the sea anemone"
Is a plant-like algae controlling the motion of an animal?
Nature continues to surprise.

I think it is really cool that a plant-like algae might be controlling the motion of an animal.
However, apparently, more directly policy-relevant science gets a lot more likes and retweets than plain old cool science.

Who Controls Whom: Algae or the Sea Anemone?

@froeltho @Knutti_ETH @Peters_Glen @damon_matthews @KatsuTanaka @oneill_bc @kasia_tokarska @JoeriRogelj Our original paper that presented a complete cessation of emissions showed a small amount of warming after cessation.
Nevertheless, conceptualizing each emission as producing another increment of warming is a useful heuristic and helpful approximation.

@jeffgoodell Sea level rise even in RCP 8.5 is projected to be less than 30 cm (1 ft) in 2050.
While 30 cm (1 ft) of sea level rise will exacerbate flooding and cause a lot of damage, I am skeptical that 1 ft of sea level rise will "erase" many cities by 2050.

I don't usually use Twitter for TV reviews, but Merrit Wever is exceptional in Netflix's #Unbelievable.

#Unbelievable, more than any other, shows women as people rather than as objects of sexual attention.
Highly recommended.

Planetary habitability - Wikipedia
Ken Caldeira
@rpancost For this to be true, one would need to define 'habitability' to mean 'habitability for some species' or something like that.
In any case, it can't be the same definition of 'habitability' used by astrobiologists.
