This is figure 1, which shows a risk map of Antarctic ice catchment basins.
The results of a study in Nature Climate Change imply that the Antarctic Ice Sheet does not act as one single tipping element, but rather as several tipping systems interacting across drainage basins. go.nature.com/4rFXQ9q 🧪
Storms that cross exceptionally warm ocean waters intensify more quickly and do more damage than storms that do not

"In one scenario at CO₂ concentrations of 450ppm —last experienced by Earth several million years ago, when polar ice was significantly reduced—Antarctic temperatures rise by 6°C while Arctic temperatures drop by 7°C due to #AMOC collapse"
We're now at ~430ppm & rising 🙈

New study finds the "canary in the coal mine" for the #AMOC: a consistent decline of the western overturning circulation, down from 20 to 15 Sv during 2004-2023 at 26° N. 🌊
AMOC "could be at or near a critical tipping point, potentially leading to its collapse".

The new Terrestrial Water Storage Anomalies (TWSA) dataset from #Copernicus Climate provides global monthly anomalies in total land water storage (soil moisture, groundwater, surface water, snow and ice) from 2002–2025 at 0.5° resolution.

So... now we can breathe again. Let's talk about ScenarioMIP.
The final version is now up on GMD - and there's some changes since the first draft. /THREAD/

Thermal infrared image of Earth. Cold high clouds are white, warm ocean is dark gray or black. In some areas it is hard to distinguish clouds from land or water because the temperature is similar. Rotated 145˚ counter-clockwise, so north is to the lower-left.
Long exposure view of Earth at Night. Blue ocean, brown desert, and green forest are all visible I between vast expanses of blue water and swirling white clouds.
I was curious what a view of Earth matching the Artemis II pic would look like from a conventional weather satellite.
Here’s a thermal infrared (heat) image from directly above the Prime Meridian at 00:30 April 3rd from @eumetsat.int (MTI1) rotated to match as closely as possible.

What if contact with nature could be part of the medicine?
Growing scientific evidence supports the role of nature-based interventions, including nature prescriptions, to promote health. 🏡
On this 🌍#WorldHealthDay, let’s #StandWithScience and reconnect with nature.

Through March, Europe's snowfall is the lowest since 1953-54. ❄️🥵
Even without El Niño, Global Sea Surface Temperatures are already hitting daily record highs.
We're now entering a climate hotter than has existed for hundreds of thousands of years!

Ancient pine trees growing in eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Analysis of tree rings clearly shows that todays storms and droughts are becoming more intense and more frequent than almost anything the region has experienced since the early 1500s.
In 2025, 50% of the globe experienced more days than average of at least strong heat stress – with “feels-like” temperatures of 32°C or higher. 🔥 At the same time, most regions saw fewer cold stress days than average.

Regional map of average energy imbalance during 2020-2024 relative to 2001-2019.
All changes in Earth's temperature are connected to changes in Earth's energy imbalance, i.e the difference between energy absorbed from the sun and energy radiated into space.
Recently, net increases have been largest in the Southern Ocean, Atlantic, North Pacfiic, and Europe.

Marcus Lacerda, o infectologista brasileiro que foi perseguido por liderar o estudo que comprovou a ineficácia da cloroquina no tratamento da Covid-19, foi nomeado diretor do TDR, uma das plataformas mais estratégicas da Organização Mundial da Saúde (OMS).
Which option do we choose - act or delay?
These are the 'warning' stripes highlighting global choices. Do we act rapidly and keep global temperatures below 2°C, or delay and end up in a 3°C world (or worse)?

Bar graph showing US temperatures by year. Blue bars going down are temperatures below 20th century average and are present in beginning of graph 1895-1970s. Orange bars most recently indicate above-average temperatures. Temperatures are rising because of climate change.
📈 It's official from NOAA. 2025 was the fourth-hottest year on record (since 1895) for the contiguous U.S. 🔥
Average temperatures for the contiguous U.S. in 2025 were 2.6°F (1.4°C) warmer than the 20th century (1901-2000) average.

Line graph time series of CO2 equivalent mixing ratio (in ppm) from 1700 through 2024 for AGGI, CO2 alone, and CO2 plus non-CO2 GHGs. There is a long-term increasing trend in recent years only.
Looks like this data was quietly updated in the fall for the latest numbers through 2024 - Annual Greenhouse Gas Index (AGGI) produced by NOAA...
It is now up to a 54% increase in the influence of greenhouse gases in the atmosphere since 1990 (AGGI = 1.54; heat trapping)
