G20 DECLARATION: Fascinating to see this doc explicitly "welcome" the "global stocktake" from COP28, which included the call to "transition away from fossil fuels"β¦
This comes after it proved impossible to secure similar language at COP30, which was also chaired by Brazil

Despite π₯ and π§ at #COP30, we are happy to share the latest info on #AMOC shutdown from @rahmstorf.bsky.social, including perspectives from Iceland and UK govs filmed after the COP venue was evacuated!
Important messages to heed as COP30 negotiations go to the wire!

It's day 12 of #COP30 and finally we have movement on the text.
In summary, it looks like the small minority of opponents of transitioning away from fossil fuels have been allowed to run roughshod over this text.
But let's dive in...
COP30 "overshoot": The latest draft "mutirΓ£o" text makes what would be a first-ever COP reference to limiting "overshoot" of 1.5C
"reiterates its resolve to pursue efforts to limit [warming] to 1.5C [and] to limit both the magnitude and the duration of any temperature overshoot"
I was just sent this image of the aftermath.

James Kirkham, Ambition on Melting Ice High-Level Group, who stressed #glacier melt is no longer a distant concern
He cited research showing between 2000 and 2023
β’ the world lost about 5% of its glacier mass
β’ some regions, such as Central Europe, lost one-third or more
Cryosphere science shows irreversible ice loss is underway, but can be slowed with emission cuts.
At a #COP30 side event, scientists warned negotiators often soften evidence, urging choices guided by science

For anyone currently in #Belem for #COP30 strolling down the river on your rest Sunday thinking I really fancy a spot of science and storytelling... I will be speaking (and floating!) at sunset (6.30 pm) on the Guama River about polar ice loss and the global ocean in a warming world. Come and join!

COP30 COMPLAINTS: At the "subsidiary bodies" closing plenary earlier, many countries were "concerned" & "disappointed" over conclusions that failed to endorse IPCC as "best available science" & failed to fully reflect latest research
Here's what they said π§΅
This should be one of the major stories of #COP30, with a much more ambitious text quashed by a small number of states

Line graph time series of October Arctic sea ice extent for every year from 1850 through 2025. Two datasets are compared in this time series. The Walsh et al. 2019 reconstruction is shown with a solid blue line. The NSIDC Sea Ice Index v3 is shown with a dashed red line only for the satellite era. There is large interannual variability and a long-term decreasing trend over the last few decades.

Last year, @michaelfwehner.bsky.social and Jim Kossin made the scientific case for a Cat6 cyclone. This week, Hurricane Melissa became the 6th storm in recorded history to smash through that threshold, with max winds of 216mph. And conditions leading to these storms are on the rise.

We can stop global warming by midcentury if we reach global net-zero COβ by 2050
Every year above 1.5Β°C raises the risk of crossing tipping pointsβirreversible ice loss, shifts in ocean circulation, ecosystem collapse, increasing economic damage due to heat, flooding, more intense storms.
Getting back well below 1.5Β°C before 2100 is still possible, but only if we act now to peak global warming as close as possible to 1.5ΛC and minimise overshoot to reduce chance of crossing tipping points and to avoid catastrophic damages.
