New paper by the World’s most prominent climate scientists shows rapid acceleration of human-caused warming, with a warming rate now that tracks to near 2.4°C by 2050, far faster than was expected, if it continues…

Vi dödar nu vår levande planet. Bestånden av djur i sötvatten har minskat med 85% sedan 1970. På land är minskningen 69% och i haven 59%. Orsaken är våra utsläpp och föroreningar, vårt överfiske och vår förstörelse av djurens livsmiljöer www.theguardian.com/environment/...

Unless there is an icecube rich drink called the neutrini at this years Nobel banquet, someone needs to be sued.

När Greta Thunberg började sin skolstrejk för åtta år sedan, argumenterade hon att det inte var någon mening att hon gick i skolan när de vuxna ändå struntade i hennes framtid:

Use your brain.

Här ni någonsin undrat över varför svensk politik verkar allt mer dysfunktionell? Kan det ha att göra med att partiet allt kretsar kring, och som dikterat regeringspolitiken i fyra år, står för riksdagens minst evidensbaserade politik? Jag gissar att det åtminstone är en delförklaring.

The world’s oceans hit 21.10 degrees Celsius last Saturday, breaking a record set in 2024. And it's only going to get worse.

⚠️ Safety first ⚠️ If you're getting ready to observe the total solar eclipse on 12 August, please follow safety rules: 🚨 use only certified eclipse glasses (ISO 12312-2)  🚨 do not look through devices without a special solar filter Check out the safety list below! 🔭🧪#EuropeanSolarEclipse

The rise in Niño 3.4 region sea surface temperatures over the past few weeks has been nothing short of astonishing. We are now hotter than any days during the 1997/1998 super El Niño event, and we are still many months from the peak.

Sure FIFA, do the love message while trump bombs Iran, murders his own citizens and throws others in concentration camps.

The Niño 3.4 region of the tropical Pacific has been hovering above 2C for the past week. This is the threshold for a very strong ("super") El Niño event, and it was reached more than a month before the prior record set during 1997/1998:

The fact that corporations are dropping their climate targets just shows that it’s still very profitable to be a polluter.

Blev lite tårögd, faktiskt.

Climate.us is officially live! After NOAA ended Climate.gov’s day-to-day operations in 2025, former team members built Climate.us to carry that work forward. Their explanations and graphics have always stood out to me as clear, accessible, and transparent. I’m really looking forward to this reboot.

We depend on nature far more than we fund it.

The world has warmed by around 1.4C since 1850. It took 148 years for the first half of that warming to occur, and just 27 years for the second half!

12 June 1929 | A German Jewish girl, Anne Frank, was born in Frankfurt. In 1942, on her 13th birthday, she received an empty diary. She perished in Bergen-Belsen concentration camp in 1945. 'Human greatness does not lie in wealth or power, but in character & goodness.' (A.Frank)

The three year running average for the global surface temperature anomaly is now more than 1.54°C above the 1850-1900 pre-industrial baseline. With El Nino ahead, expect this to keep rising over the next two years.

Use of Sun and Stick for direction. ✍️ 1. Place a stick upright in the ground. 2. Mark the tip of the shadow cast by the Sun. 3. Wait 15-30 minutes, then mark the new shadow tip. 4. Draw a line between the two points — this line runs East-West. 5. The first mark is West; the second mark is East.

Emmy Noether (1882 – 1935) was a German mathematician, described by Einstein as the most important woman in the history of mathematics. She developed many leading theories of rings, fields, and algebras at a time when academia was mostly closed to women. #CelebratingWomen

Sir David Attenborough 100 år! 🎉 "It's surely our responsibility to do everything within our power to create a planet that provides a home not just for us, but for all life on Earth."

CO2 levels in the atmosphere hit an average of 431 ppm in April, setting a depressing new record. The data comes from the Moana Loa Observatory. Under the proposed 2027 budget, its funding would be cut to $0. Latest for @sciam.bsky.social. www.scientificamerican.com/article/carb...

May the fourth be with you and remember.

Here's your Sunday-morning El-Nino forecast, holding steady at 2.5°C, using the "relative oceanic nino index," or RONI. The previous high RONI was 2.5°C in the 1982/83 El Nino, so this El Nino is shaping up to be at least tied with the strongest on record since 1950.

🌡️ Europe is the fastest‑warming continent, warming at more than 2× the global average. Changing weather patterns, reduced air pollution, declining snow cover & proximity to the rapidly warming Arctic all play a role. ⬇️
