For those clinging desperately to phrases like: “it’s all caused by arsonists”, well it looks like the arsonists have really, really upped their game lately. #wildfires

Back in 2012 we did a figure comparing historical emissions to previous generations of emission scenarios. rdcu.be/brDGx Surprisingly, the figure is still doing the rounds. We update it every year, with many interesting changes primarily due to revisions in land-use change emissions. 1/

Scientists and local stakeholders in Kerala, India recently came together to talk sea-level rise, shoreline change, algal blooms and how to adapt a coast under pressure. Clear needs. Strong local voices. Useful science. Full story here: nersc.no/en/features/...

India’s coastline faces rapid environmental change – nowhere more visible than in the state of Kerala. A recent conference brought together international and

Where do our CO2 emissions come from, and where do they end up? I made this little summary - and you can see why reducing the use of fossil fuels remains the most important tool we have for slowing climate change:

How old is the sea ice in the Arctic, and why does that matter? We’ve just released a new sea-ice age dataset covering 1991–2024. It helps researchers track the decline of older, thicker ice & improve climate studies, model evaluation & safe traffic in the region. @met.no nersc.no/en/features/...

Winter has arrived properly in Norway this week ❄️ After a few days of heavy snow it already feels like mid-season, so it’s time to look a bit further ahead. I’ve built a small interactive tool to explore ECMWF seasonal snow forecasts for the Nordics: climatecompass.shinyapps.io/Snow_Depth_F...

Sarcasm aside, it's perhaps worth pointing out that the evidence suggests that weather disasters reduce economic growth for decades - the idea that there's rapid bounceback, or even extra growth stimulated by recovery, has proved wrong www.newscientist.com/article/mg23...

We all get poorer every time a climate disaster strikes

Long-term economic effects of global warming could be far greater than thought, making many countries poorer and hurting even those of us spared direct impacts

A reality check for me was working with students on an internal carbon accounting platform that Bon App our food provider uses. Beef was less than 5% of our purchases but around 50% of our food emissions even with international work to be plant forward. apnews.com/article/plan...

Scientists are presenting new evidence that the worst effects of climate change can’t be avoided without a major transformation of food systems.

Growing wealth inequality is devastating for societies. But with headlines like “the wealth of the top 1% reached $52 trillion”, the topic gets ignored — because those numbers mean absolutely nothing to anyone.

I am happy to announce that we received major funding from Schmidt Sciences under their VICC program to study rapid #Permafrost Thaw Carbon Trajectories (PeTCaT). The 5-year project led by my team @awi.de partners with an international team to quantify how rapid thaw contributes to climate change.

one of the smart things that Newsom is doing here is implicitly calling out the insanity of how much Trump has been normalized by media by forcing them to think about what it looks like when somebody else does it

Newsom keeping up a strong troll game:

One Boston block was 94°F. Just a few streets away, it was 103°F. Hyperlocal heat data can pinpoint where cooling projects will save the most lives (and money). buff.ly/pgSujfI

Inside an urban heat island, one street can be much hotter than its neighbor – new tech makes it easier to target cooling projects

New technologies are making it easier to find these urban heat islets, opening the door to new strategies for efficiently improving community health.
