In the last decades, the world has made fantastic progress against extreme poverty. In 1990, 2.3 billion people lived in extreme poverty. Since then, the number of extremely poor people has declined by 1.5 *billion* people. 🧵

Now that the Sept and Oct data are (belatedly) in, it looks like 2025 will be the second warmest year in the record (~80% probability). The last three years are in a class of their own.

For today’s theme, “Lines,” I created a miniature globe of NASA SVS’ Global Sea Surface Currents and Temperature visualization. Look closely to see the mesmerizing ocean eddies!

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

NASA is more than rockets and moonwalks. NASA is behind much of our everyday technology. From space discovery, to Air Jordans, to CAT scans, NASA has played a role. We get it all on less than a penny of every federal dollar. Now their science may be gutted by 50%.

A few tips:
1: Open up your aperture as much as you can for more bokeh. Faster lenses are better.
2: Make a mark on your focus ring + lens (I use two narrow strips of masking tape) so you can quickly and repeatedly hit your in-focus point.

Former DOGE engineer says federal waste and fraud were 'relatively nonexistent'

I get annoyed at the narrative that all the awareness and work on climate change hasn't done anything. Yes, global CO₂ emissions indeed continue to climb, but we don't know the counterfactual. When I was in grad school, we were on track for 5°C of warming. Now it's below 3°C. That's progress.

Let’s make today (May 10) Magnetosphere Appreciation Day!
A year ago today we had that huge aurora display, caused by the most powerful geomagnetic storm experienced in decades.
Lovely visualisations by NASA SVS/NASA DRIVE science centre on how our atmosphere and magnetosphere responded.

As summer in the Northern Hemisphere approaches, it is important to keep in mind how temperatures are changing 🌡️
Shifting distribution to the right ➡️ increasing societal risks from extreme heat
The driver? Humans... The burning of fossil fuels
