El Niño 2026–27 as a polycrisis 🇨🇦 Canada faces a potential polycrisis: extreme heat, wildfire smoke, flooding, energy insecurity and pressure on healthcare colliding and amplifying each. But Canada is not alone. Every country faces its own interconnected risks. theconversation.com/el-nino-2026...

El Niño 2026-27 as a polycrisis: What happens when health and energy systems fail simultaneously?

How the ‘super’ El Niño could trigger a polycrisis: interconnected failures that neither the energy system nor the health-care system can prepare for alone.

9) The remaining carbon budget. That is the amount of CO₂ humanity can still emit while limiting global warming to 1.5°C, 1.7°C or 2°C. Time is up for 1.5°C. The remaining carbon budget for 1.5°C is down to 150 GtCO2, that is less than 4 years of current emissions.

Remaining carbon budgets for 1.5, 1.7 and 2°C

Models show how increasing atmospheric CO2 drives the land and ocean sinks while climate change reduces the sinks. For the 2016-2025 period, the land and ocean CO2 sink are respectively 19% and 8% smaller than what they would have been without the effects of climate change and variability.

Just to put a bow on this: When Musk announced the Cybertruck in 2019 he said it would available in late 2021 and cost $40k. He and Tesla bulls hyped the 1.5 million “waiting list”. He projected 250-500 k sales/year. It showed up in late 2023 It cost $100k Lifetime sales (wait for it) 71k

Good to see this. Most of the energy podcasts in my feed are not really engaging at all with the climate impact of data centres. It takes @ketanjoshi.co to spell out the very simple fact that clean energy tech only supports decarbonisation if it’s displacing fossil fuels.

Today on Volts: most of cleantech world seems to have accommodated itself to giant AI data centers, but @ketanjoshi.co is having none of it. He's been a relentless critic, tracking the hyperscalers' broken climate promises, rising emissions, & abysmal community relations. We get into all of it.

Google was really trying to hide its water use figures, to the degree that it got the council to try to keep its water use figures secret. The community finally got the actual numbers and found out Google was using 29 percent of the water in the community. www.wired.com/story/what-t...

What the US Movement Against Data Centers Can Learn From Abroad

Paris Marx, author of Hyperscale, has been tracking global data center development for years. The US has a lot to learn from what’s happened everywhere from Ireland to New Zealand.

Every Friday I do a bit of #dataViz to plot Covid-19 wastewater concentrations. Based on this and the RIVM plot, it seems promising that this would be another calm season. Something has changed in Covid-19 epidemiology in 2025. 2022-2024 multiple large waves. 2025-2026, single low wave.

Se on #pandemiaPerjantai ja uudet @thlfi.bsky.social #SARS-CoV2 #jätevesi datat. Päivitetyt kaaviot, olkaa hyvät! - syysepidemia etenee hissukseen - määrät edelleen alhaisia - näyttää viime vuoden toistolta, jolloin jäi matalalle

Graphs with Sars-CoV2 virus amounts in wastewater across Finnish cities.

For 25 years we responded to jobs crises by encouraging STEM degrees and entrepreneurship. Today, AI disruption is most acute in STEM fields & AI politics has decimated their external funding. HigherEd over-invested in those degrees and are cutting humanities, which are more resilient.

To bring two threads together here: The job market sucks extra hard due to AI pressure on supply and demand. There are too many apps AND too few real jobs. Future of work rhetoric is that there isn’t a future for work. Social policy is pretty much mum on how we should fix that.

So if you’re an American, “safety restrictions” prevent the AI from saying who won recent presidential elections. If you’re Canadian, apparently it’s safe to tell you. That is some creepy dystopian shit right there.

Your monthly reminder that if you're using ChatGPT to do your science, you're failing your colleagues, community, and all of us. Here, ChatGPT makes up data and presents it as the real thing — then apologizes when confronted.

For the actual figure, use matched populations and treatments in both panels, with means and uncertainty. The teaching point is immediate: hybrids survive better, but wild plants reproduce more—viability and fecundity selection oppose one another.















fucks sake don't make up the data














You’re right. You asked for a sketch from Mercer, and I gave you invented bar heights. Labeling them “illustrative” doesn’t make that appropriate. I should have obtained the actual data or told you I couldn’t access them.
