The “jaw-dropping” El Niño currently heating up the planet has burst through the highest temperature ever recorded for the phenomenon, several months before its expected peak.
A line chart showing temperature anomalies in the Niño 3.4 region of the Pacific Ocean, compared to a 30-year rolling base period since 1982.

A gold line shows temperatures in 1997, a teal line in 2025, and a red line in 2026. The red line surpasses all others reaching 3.07ºC, and at an earlier point (September) than the previous El Niño that reached a comparable range in November 2015.

Yet another measles death here in PA. That's two in 4 or 5 days, and this one was an 18 year-old. And of course, unvaccinated. There is no limit to my contempt toward those who continue to undermine vaccine confidence in the face of these avoidable tragedies. www.inquirer.com/health/fourt...

May I remind everyone that there is currently NO cure for rabies. May I also remind everyone there is absolutely NO scientific proof connecting ANY vaccine that we produce today with autism. This is true regarding vaccination in both humans AND in dogs. Vaccinate your pets please.
Worries about vaccination rates in dogs
As rabies seems to be spreading more in wildlife, veterinarians are especially worried about vaccine hesitancy spreading among pet owners, a dangerous trend that could lead to more dogs - and their owners
- becoming infected. A 2023 study published in the journal Vaccine found in nationally representative
sample of Americans that nearly 40% believed canine vaccines were unsafe and 37% believed that vaccines could lead their dogs to develop cognitive issues, such as autism.

Over the weekend, a storm in the Baltic states caused significant disruption to power supplies and at least 2 deaths. An experimental reanalysis-based attribution approach suggests that ~20% more rain fell than if the same weather pattern had occurred in a world that was 1°C cooler.
A Baltic storm caused significant damage on 22nd August 2026, but more rain fell than would have done had the world been cooler.

“One mile on a bike is a $.42 economic gain to society, one mile driving is a $.20 loss.” “Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath Some costs are savings.
