New gas won’t fix a broken system. It’s time to phase out fossil fuels Climate impacts ranging from fires, floods, heatwaves, extreme cyclones and drought are already reshaping communities, livelihoods, and insurance policies across Australia.

Analysis from ACCR found that major oil and gas companies would deliver about US $78 billion more value by stopping fossil fuel exploration and returning capital to shareholders.
Fossil fuel exploration is not a growth engine; it’s a drag on returns. thepoint.com.au/opinions/260...

One of the cool things about living in UK is you can wake up one day & find out you reside 300 yards from an ancient Roman road. (h/t @davidho.bsky.social)

Today, it has become the smallest emitter among all sectors.

Time series of the oceanic nino index from 1950 to 2025. Labels are shon for El Nino or La Nina conditions. There is significant variability over time.

I've added a new graphic to my climate indicators page, which shows the Oceanic Niño Index (ONI) used for monitoring El Niño/La Niña conditions. I will update it each month at zacklabe.com/climate-chan....

Major US climate website likely to be shut down after almost all staff fired Exclusive: Climate.gov, which supports public education on climate science, will soon no longer publish new content

Scoop: NOAA's climate portal, climate.gov, will soon no longer publish new content after its staff were recently dismissed.

Former staff fear that the website may become a mouthpiece for the administration's anti-science views.

Measles Heatmap of the number of cases of measles from the 1920s to the 2010s in the United States, shown by stage. Blue is low, red is high. The chart is annotated with a black line that shows the date of the introduction of the vaccine (approx 1963) and the number of cases drops dramatically right after.

Heatmap of vaccines reduced measles cases across US states From 1929 to 2022 There are lots of cases before 193, then it drops and almost disappears completely in the 1990s. 1963: The first measles vaccine is developed by John Enders 1971: The measles-mumps-rubella (MMR) vaccine is developed by Maurice Hilleman 1980: It becomes mandatory for children entering kindergarten to be vaccinated against measles Data source: Project Tycho (2018); Centers for Disease Control and Prevention (1959-2022) OurWorldinData.org - Research and data to make progress against the world's largest problems.

Scientists have been publishing climate models since ~1970.

A good way to evaluate their skill is to compare what they expected to happen in the years after the model was published to observed climate changes.

It turns out most models were pretty spot-on:

SUVs Make Traffic Worse And Are More Dangerous Than Cars Two new research papers show the downsides of upsizing our vehicles. SUVs have a disproportionate impact on traffic jams, and they injure more people than cars

My latest Forbes article is all about SUVs. Specifically, it delves into two new research papers - one from traffic engineering, and one from public health - that shows how these increasingly-popular (and increasingly large) vehicles come with major downsides 🧪

Pope Leo XIV Might Be the Climate Champion We Need The new pontiff appears inclined to follow in his predecessor’s green footsteps.

En 2023, les catastrophes naturelles ont entraîné des pertes mondiales pour 247 Md€, dont 95 Md€ ont été couverts par une assurance (+21% sur 10 ans).

Les tempêtes convectives violentes (orages et vents violents, fortes pluies, grêle, tornades) sont la première cause : 57 Md€, le double sur 5 ans.

This is wonderful
