Important updates from @agu.org for those attending #AGU25 in New Orleans as the city is invaded by federal paramilitaries in operation “Catahoula Crunch”

Coral reefs have orchestrated Earth’s climate for 250 million years Coral reefs have shaped Earth in much deeper ways than we usually appreciate.

I know you all are running away from the US, but we don't see too many positions like this opening up, and Miami has a really nice group in the geo department. ⚒️

Letting Silicon Valley Geoengineer the Atmosphere Will End Badly We already have plenty of evidence of what happens when things better left to governments — which in this case might decide to never flip the switch at all — are ceded to private industry.

My take on the general idea of having for-profit companies involved in the field:

Analysis: Fossil-fuel CO2 emissions to set new record in 2025, as land sink ‘recovers’ - Carbon Brief Carbon dioxide (CO2) emissions from fossil fuels and cement will rise around 1.1% in 2025,...

For more details, see my @carbonbrief.org article with Global Carbon Budget lead @pfriedling.bsky.social: www.carbonbrief.org/...

And the new Global Carbon Budget paper: essd.copernicus.org/...

Two years ago today - 2C or not 2C, that is the question

How much carbon budget do we have left if we want to stay below 1.5˚C?

Just 2 more years at current rates. It is essentially impossible to avoid global temperature rise exceeding 1.5˚C.

Aboveground biomass in Australian tropical forests now a net carbon source - Nature A transition from carbon sink to source for the aboveground woody biomass of moist tropical Australian forests has occurred, driven by increasingly extreme climate anomalies.

Bad news for large natural carbon sinks: "Our findings suggest the potential for a similar response to climate change by woody aboveground biomass in moist tropical forests globally, which could culminate in a long-term switch from carbon sinks to carbon sources."

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope.

According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

I think this is one of my favourite colourful climate chart type things, because it depicts two things at once:

- Things are going to get worse, no matter what

- The degree to which they get worse depends on decisions made today

There has been a lot of recent interest in mitigating "super pollutants", short-lived climate pollutants like methane and refrigerants. We should cut emissions, but using them as carbon offsets risks breaking the math of net zero: www.theclimatebrink....

The Southern Ocean May Be Building Up a Massive Burp - Eos Modeled results suggest that if anthropogenic emissions decrease and the atmosphere cools, heat stored in the Southern Ocean could be released abruptly in a few hundred years, kicking off a temporary ...

Excuse you! If humans can reach net negative carbon emissions over the next few centuries, researchers suspect the Southern Ocean will “burp” built-up heat into the atmosphere. eos.org/research-spo...

Here's an awesome trick - measuring ocean acidity with sound. It's a bit of a gimmick since you really need to tune the instrument per site, but potentially may open a low-cost monitoring tool if developed further. 🧪🌊

The Labor govt's 2035 target of 62% reduction in net national GHG emissions below 2005 emissions levels is aligned with >2.4°C of warming (above pre-industrial levels)

Not sure how destructive it'll be cos 2.4°C is BEYOND the range of this Climate Council infographic warning of appalling impacts
