Breaking: New study using observational constraints projects that the Atlantic Ocean circulation #AMOC will weaken ~50% by 2100, even for medium emissions and without Greenland melting. Seriously bad news.

ALT Photograph of Earth captured by the Apollo 17 crew on December 7, 1972. Earth takes up most of the image. Dark blue ocean water and swirling white clouds are visible. Africa is a large brown landmass from the center to the upper left, stretching from about 9 to 12 o'clock. Clouds cover most of the 6 o'clock. Credit: NASA
ALT A full disk image of Earth, as seen from the Orion capsule. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. From about 8 to 9 o'clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o'clock spot, aurora glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space. Credit: NASA/Reid Wiseman

Butterfly populations across the U.S. are in alarming decline, according to a 2025 Science study, with total abundance falling by 22% in just 20 years.
Such widespread and worrisome losses portend broader environmental threats and emphasize the urgent need for conservation action. scim.ag/3FaRKdU #ScienceMagArchives

For the second consecutive year, winter sea ice in the Arctic reached a level that matches the lowest peak observed since satellite monitoring began in 1979.
On March 15, Arctic sea ice extent reached 5.52 million square miles, @NASA and @NSIDC report. go.nasa.gov/4lTiO2x

Over the past 10 years the observations are remarkably consistent with the standard (#CMIP6) model projections, including the 2023-2024 El Nino-driven global temperature spike. Watch this space for more on this soon...

Not to sound like a broken record but... Over 200 new record high temperatures are forecast this week. 🥵
Record warmth will persist across portions of California, the Southwest U.S., the central Great Basin and will return to areas of the central/southern Plains and mid-lower Mississippi Valley later this week.
Stay cool this week, check weather.gov.

Climate deniers keep posting ice-age graphs as if they weaken the case for CO2. They do the opposite.
If tiny orbital changes can help flip the planet when amplified by feedbacks, that’s evidence of a high-gain climate system — not a low-sensitivity one. CO2 is part of the amplifier stack.

🚨: This isn’t our Galaxy. 😳
You’re looking at billions of stars in the Andromeda galaxy, captured by the Hubble Space Telescope—and almost every one likely has planets. Let that sink in.

Significant acceleration of global warming since 2015, finds news PIK study with @rahmstorf
Recent warming: around ~0.35°C per decade.
1970–2015 average: just under 0.2°C per decade.
➡️Current rate is higher than in any decade since records began in 1880.
