Breaking News!
Code UFB!!!

Antarctic sea-ice extent just set a new record daily low on Sept. 30, beating the previous record set in 2023 by over 15,000 km².

Current extent is 3.85 standard deviations below the 1991-2020 average.

@PaulGreenWire Each new creation from you is a pleasure to see. Have you done a gannet yet?

Turns out 2026 officially was the hottest summer ever recorded in Western Europe. We’ve seen droughts, heat deaths, dry rivers. This will become more common. Cities and farmers must adapt to an uncomfortable new normal. Source: https://t.co/Ul1XxLG0ET

[Prof. Eliot Jacobson @EliotJacobson]

As of September 10th, the Nino 3.4 anomaly is now 2.94°C (preliminary) above the 1991-2020 baseline, setting the 104th consecutive daily record, a full 1.09°C above the previous record for the day, set in 1997.

The Climate 8-ball is gobsmacked.

[Peter Dynes @PGDynes]

August 2026 was tied for the hottest month ever recorded globally. W. Europe also experienced its hottest summer ever. The consequences reach far beyond temperature charts: dry soils, depleted rivers and damaged harvests. And this could be the coldest summer from here on.

@theepicmap No, 95% that comes from rivers, come from these 10 rivers. https://t.co/X4oGz9Y00h

Tall but Shy.

Before Columbus.
Before the Inuit.
There were the Dorset.

They left no cities.
No words.

Only silence and ivory carvings of bears so still, they feel alive.

And then, they disappeared.🧵

Fifth and final pass through Hurricane Melissa for our crew today. Just after noon entering from the NW corner exiting SE.

My own little disappearing icefield study. I have followed this small glacier on Kvaløya since 2009, and warmer summers lately seem to have an impact. Pictures below are from sept 13. 2022 and same date 2025. Gone in 2037?

The Northern Pacific Ocean is currently smashing temperature records.

And it is reaching these levels far earlier than the current generation of climate models had expected.

A short thread 🧵

@cormac_mcginley We get them here too..

[Thomas Reis @peakaustria]

It's bizarre (or maybe it's not) that no one talks about this but the rate of change of current global warming...averaging 0.2-0.25 C/decade...is greatly outpacing the ability of vertebrate lifeforms to keep up. Even if you accept the IPCC's (likely) conservative projections on the global temperature rise, we're basically talking a 3-4 C rise in temperature relative to pre-industrial, much of which will have occurred since the 1970s. A compression of change normally (in the ice age cycles) over thousands of years into 130-150 years. I hear climate scientists say we're returning to these certain ancient climates from hundreds of thousands to millions of years ago. This is true. But, to do so over the course of just century or less is truly cataclysmic for complex biological organisms.

So, when I've, in the past, also heard some say, "well +4 C isn't as bad as +6 C", I scoff because, well +4 C just as a global temperature anomaly threshold is still by itself a hell world for current life adapted to interglacial conditions. But, the pace we're taking to get there...is like taking life to the butcher house. It's too damn fast. And humans are mammalian lifeforms who need other life to survive like any other mammal. We just can't move our agriculture to different soils on a dime. Extinction rates are already accelerating because of other environmental issues (deforestation, for example). Rising by +4 C over 4,000 years would lead to extinctions. +4 C in 130 years? Or less? Life is resilient, but the more complex it is, the more it depends on other life to survive.

The fact that the pace of change and the effect on biology and ecology are never discussed is like a glaring hole in the climate conversations. People (and I'm guilty of this as well) post these graphs (see below) showing the monstrous spike in global average temperatures relative to tens of thousands of years of history, but the biological/ecological implications of that are just not thought about. We cannot ignore it though. The assumption that things will remain all hunky-dory (basically, we just have more weather disasters, but nature and us will be somehow fine as far as food, water, etc.) is absurd. But to have such a discussion would be a realization that maybe we've lost control of the situation more than we wish to realize.

Civilization is a fragile structure. Take away food (because of depleted agricultural production and the ecosystem processes ag depends on) and the whole deck of cards collapses. Ag was the whole reason civilization developed. And that's just climate...set aside rapid topsoil losses globally, the rise in dead zones in the ocean, and the conquest of greater amounts of land (and deforestation) for agriculture and urbanization.

I've tried in recent years to remain somewhat optimistic about the future based on the fact that, well...I'm a scientist not a crystal ball. There's a lot of uncertainties in our understanding of things. But, seeing what's happening with climate over the past couple of years and especially this year, I realize the uncertainties seem to revolve more about timelines than the path itself. The path is ugly. And the result is the same whether it be 2030 or 2070. It's in a blink of an eye as far as Earth is concerned. We need a miracle at this point and I'm not sure what that would be.

Sorry, the doom is hitting me hard this week, but I know what I know and what I see. Via Nick Humphrey Metrologist

Dette må være noe for dere, @Meteorologisk . Vi finner alt for mange værsonder i fjæra.

[Yohan @YohanHadji]

600'000 radiosondes ($100M) are lost in nature each year after being used for only 2h.

The Meteoglider returns to home after each flight to be reused.. it has been tested by national weather services in Switzerland, France, Spain and Denmark. @NOAA it's your turn!

[Per-Erik Schulze @PerErikSchulze]

Today: Breakthrough for high quality marine protection in Norway! The government introduce three big zero-fishing zones. First time the use this tool. Placed in the Oslo fjord, where the cod stocks and ecosystem are near collapse due to overfishing and pollution.

@SteelySeabirder Kayaking w loads of puffins and auks outside Tromsø. Can't get much better than that.
