Under @NASAArtemis, we’re going back to the Moon. This is why. 🌙

"The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision."

Den nye Europeiske plattformstudien for COVID-19 og fremtidige pandemier, EU-SolidAct, har nå startet å inkludere pasienter ved norske sykehus. Studien skal gå i 15 land og ledes av OUS. https://t.co/Iw5hwQ6lZs /

The WHO just updated its page on how COVID-19 transmits. Those few sentences on aerosols represent one of the most crucial scientific advances of the pandemic. My NYT piece on the century-long history of the error, the year of delay—and what it means now. https://t.co/B9y2Mf6LC7

UNEP: 1.5C climate target ‘slipping out of reach’ | @hausfath @robbie_andrew https://t.co/dGUfgnvRXP

The climate and nature crisis that we face will not wait for anyone.
There is no time to waste, and Europe is wasting no time.

[Johan Rockström @jrockstrom]

10 years ago science showed there are 15 known Earth tipping elements that regulate the state of the Planet. Today we present findings that 9 of these 15 systems are on the move. There is now scientific support for declaring a state of Planetary Emergency https://t.co/eahKmOnUxg

Temperature over land rising twice as fast as global average, already 1.5°C above pre-industrial, #IPCC Co-Chair Panmao Zhai shows at Hong Kong Observatory @weather_hk #ClimateChange

[Michael Flammer #KlimaVor8 @Jumpsteady]

This is important.
Professor Will Steffen: "Unfortunately this is the way 99.9% of the time scientists present projections for the future. You got to do it another way… There aren’t many scientists who think we will actually meet the 1.5°C target."

[AukeHoekstra @AukeHoekstra]

In 2017, assuming an energy system running on 100% renewables (solar, wind and hydro) was considered frivolous by most 'experts'.

In 2017 @mzjacobson was strongly condemned after he quantified a possible 100% RE route for the USA.

But in 2018 the dam broke!

@OddBjornSalte Bonus: 12 milliarder mennesker kan leve med vårt (vestlig) energiforbruk om vi dekker 1/3 av sahara med solceller. 👍

[Simen Walberg Schive @simenws]

@OddBjornSalte Tja, oslo har 14 kvkm flate tak, i tillegg masse skråtak. Det kan være en start? Jeg tror bare vi ikke har tid til å vente på kjernekraft/thorium, og sol er allerede billigere. Hvorfor er ikke Norge ledende på off-shore vind, forresten?🤔

[Tom Randall @tsrandall]

This @exxonmobile chart from 1982 predicted that in 2019 our atmospheric CO2 level would reach about 415 parts per million, raising the global temperature roughly 0.9 degrees C.

Update: The world crossed the 415 ppm threshold this week and broke 0.9 degrees C in 2017 1/

[Event Horizon 'Scope @ehtelescope]

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun
