This disease has existed on Earth for less than a year. We should not allow ourselves to be cavalier about young people getting infected just because very few of them have died. We have no idea how this affects people’s health in the long term.

You could tag me, @Wired ! I’m right here!

San Francisco right now vs the surface of Titan (images by Douglas Zimmerman@SFGate  & the Huygens probe ESA/NASA/JPL/U Arizona). Both skies orange due to the scattering of light by small particles in the atmosphere: smoke haze for SF, hydrocarbons/tholins for Titan.

Venus has been considered a potential location for extraterrestrial life for decades. On the surface, of course, you'd be crushed & incinerated immediately. About 50km up, though, the temperature & pressure are fine: you could in principle survive with just heavy-duty scuba gear.

The smoke from the West Coast fires has stretched all the way across North America now. Here's a visualization of vertically integrated smoke from @NOAA_ESRL 

In case you missed it, my book about the end of the universe was a @nytimesbooks  Editor’s Choice this week! #EndOfEverythingBook 

Asking anyone to “not be political” right now is asking them to remove themselves from humanity and be indifferent to the lives of others.

You’re not experiencing higher than usual call volume, this is your call volume, we all know we are gonna have to wait


If someone's political stance requires preventing scientists from informing you about your own planet, that's not politics, it's oppression.

Kinda looks like the billionaires aren’t going to save us

Retweet if it's by absolute sheer meaningless luck that you weren't born in Syria with bombs falling all around you, desperate for refuge.

Scientific evidence suggests human-caused climate change is making extreme weather events more common. This is not a political statement.

Public health experts: don't bring students to campus, there will be outbreaks Profs: please don't require in-classroom teaching, there will be outbreaks Staff: this isn't safe, there will be outbreaks <outbreaks occur, campuses close> Admins: no one could have predicted this

Please do not fall prey to the idea that any activity that does not measurably advance your career is somehow necessarily harming it. You have only this one beautiful life; do not avoid living it for fear that your total productive output might be less than the theoretical max.

[Cake voice] We’re KEEPING our DISTANCE We’re all QUARANTINED We stay alone (ALL ALONE), for our friends in their time of NEED

Any president who would prefer civil war to being removed from office does not love their country and is certainly not serving it

Any organization that justifies bringing workers back into offices by touting their hand sanitizer and desk spacing is completely unserious. Show me your HEPA filters and ventilation system diagrams. Is your AC recirculated? Where is the air flow? What CO2 levels do you reach?

So, hypothetically… if you control every branch of power, kill a couple popular programs for no reason, then try unsuccessfully to use them as leverage & end up shutting down your own government… maybe you are bad at governing & shouldn’t.
