This El Niño Is a Warning

1 Share


This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.

El Niño is here.

The world’s largest ocean slipped into the weather pattern in the spring, according to the National Oceanic and Atmospheric Administration, and the sea surface is now significantly warmer than average in one important region. When you chart ocean temperatures on a map, the “El Niño tongue” (yes, that is what scientists call it) clearly appears:

A chart of average relative sea surface temperature anomalies from July 12th, 2026, to August 8th, 2026. The El Ni\u00f1o tongue is clearly visible against an overall colder-than-average background. NOAA

It might be more accurate to describe El Niño as something that happens to the planet, though. The Pacific occupies about one-third of Earth’s surface. When that third becomes unusually warm, it transforms weather around the world, driving wetter conditions in California, Central America, and South America; and drier weather in Asia, Africa, and Australia.

So far, so normal. El Niño is a standard fluctuation in the Earth’s climate system; we experienced the last one in 2023 and 2024.

But that is roughly where what’s normal about this year’s El Niño ends.

For one, this El Niño is far more intense than we should expect at this time of year. In an El Niño, the Pacific’s average temperature usually rises through the end of December or so; the phenomenon’s original name in Spanish, El niño de Navidad, alluded to the surprising arrival of warm currents in South America around Christmas. In the modern satellite era, the warmest El Niño ever measured happened in 2015, and ocean temperatures peaked at 3.1 degrees Celsius in November and December of that year. We called that a “Super El Niño” for just how abnormal it was.

Yet the Pacific is already more than 2.6 degrees Celsius (or nearly 5 degrees Fahrenheit) above normal — making this the third strongest El Niño ever measured in the satellite era — and it is only August. We still have four months to go, and this El Niño is already a record-smasher. More ominously, models expect that this El Niño could eventually grow to more than 4 degrees Celsius, or 7 degrees Fahrenheit, above normal.

What will that mean for the world? According to a recent Science study, the average El Niño can cost the global economy more than $3 trillion. The world is richer now than it was a decade or two ago, which should make it better able to withstand disaster. But this El Niño is so far out of sample that it’s hard to know what it could do.

And perhaps more importantly — as the climate scientist Zeke Hausfather, the guest of our new episode of Shift Key says today — it will offer a kind of preview of what the planet’s normal climate will resemble a decade from now. This El Niño is likely to push 2027’s average temperature above 1.5 degrees Celsius, the nominal threshold at which countries hoped to limit warming as part of the Paris Agreement (although, as you’ll hear, it is slightly more complicated than that).

Which is all to say: I encourage you to listen to our new episode, which is available on Apple, Spotify, or RSS. (A transcript is also available for Heatmap subscribers.) We tackle questions including:

  • Why do the models think this El Niño will be so bad?
  • Why do we believe this El Niño could be the worst one in 500 or 1,000 years?
  • Is climate change getting worse faster than we thought it would — is it accelerating?

There’s one thought that I didn’t include in the episode, however. Since late 2023, political discussion of climate change has decreased. This isn’t a phenomenon limited to any one faction of the Democratic Party — the progressives Abdul El-Sayed and Zohran Mamdani have downplayed climate policy roughly as much as, say, moderates like Mary Peltola and James Talarico have — but it is a clear trend. The American media’s coverage of climate change has declined during the same period. This “climate hushing” is not because politicians stopped caring per se, I think, but because nobody is sure how to talk about the issue in a politically useful way anymore, especially after the “climate = jobs” rhetoric that underpinned the Biden administration’s policy failed to retain voters in 2024.

I don’t believe (and think that political science has disproven) that extreme weather can “awaken” the public to climate change. Even against a gradually warming baseline, the weather — and public attention — shift far too often for that. But media coverage is loosely responsive to events. When the super El Niño of 2015 and 2016 smashed the then-record for the hottest year ever measured, it helped initiate a new era of public and elite concern about climate change. That El Niño’s heat waves, wildfires, and mass coral bleaching previewed the far worse disasters of the decade that followed. This El Niño’s disasters and broken temperature records could be worse — and even less ignorable.

Canada has higher measles rate per capita than U.S.: WHO data

1 Comment

Measles data from the World Health Organization show that Canada has half the number of confirmed cases as the United States, despite having a population only about one-tenth the size of its neighbour.

WHO says 47,459 measles cases have been confirmed across the Americas as of July 18, which is three times higher than the total reported cases all of last year in the region.

The United States has 2,260 of those cases, while Canada has confirmed 1,107.

The WHO says the disease has claimed 45 lives so far this year in the Americas, largely in Guatemala and Mexico.

It says in an alert that the Americas need to strengthen their vaccination, surveillance and rapid outbreak response measures amid rising measles cases across the region.

“Measles leaves no room for complacency. We know how to stop it: achieving high vaccination coverage, detecting suspected cases early, and responding rapidly to interrupt chains of transmission,” said Daniel Salas, the executive manager of WHO’s regional office for the Americas called the Pan American Health Organization, in a news release.

“Every outbreak exposes immunity gaps that must be urgently addressed, particularly among children, under-vaccinated communities, and populations with limited access to health services.”

PAHO said North and South America are seeing their highest number of confirmed cases in more than two decades.

Roughly 186,000 measles cases have been reported worldwide as of July. That’s a 12 per cent increase compared with the same period last year.

For Russell Vought and His Theocrats, Women’s Job Loss Is a Feature, Not a Bug

1 Share

And “Russell Vought and His Theocrats” is the worst band name EVAR. July’s U.S. jobs numbers dropped last week, and they are awful for some people (boldface mine):

Women accounted for 100 percent of the decline in the labor force in July, according to a National Women’s Law Center analysis of the Bureau of Labor Statistics’s latest dismal jobs report.

Overall, the economy lost 23,000 jobs in July: Women lost 32,000 jobs, while men gained 9,000. Many of the jobs lost were in local government and leisure and hospitality—real jobs that real women, who are already dealing with slowed wages and rising inflation, work.

Meanwhile, a whopping 165,000 women exited the work force last month, meaning they were neither working nor looking for a new job. The number of men in the labor force remained steady…

In fact, more than double the number of women have left the labor force than men since the start of the year. A total of 845,000 women have left the workforce since January, while 406,000 men have left.

It’s hard not to see these startling statistics as part of the Trump administration’s broader campaign to undermine women’s rights and autonomy.

Fascists have always viewed women as secondary to men, especially when you add in the supposed need to strengthen the Volk restore fertility rates. Women losing jobs, especially Black and brown women, is not a bug for these assholes, but a feature.

The problem, over the long term, for conservatives is that the U.S. economy is structured such that we need women working: employers need the employees (especially with the crackdown on immigration), and households need the income. The last bit is critical electorally–many people have bills to pay and their household can’t afford to lose a substantial chunk of income.

Unfortunately, over the short term, life is going to suck for those women who voted for and against the fascists. The latter don’t deserve this crap.

First case of scrapie detected in U.S. sheep in more than 5 years - Farm and Dairy

1 Share

The U.S. Department of Agriculture announced Friday that a case of scrapie was detected in a sheep in Oregon. This is the first case of scrapie found in the U.S. in more than five years.

The USDA Animal and Plant Health Inspection Service confirmed classical scrapie in a sheep slaughtered at a facility in Oregon.

According to the Oregon Department of Agriculture and American Sheep Industry Association, the animal was tested as a routine part of USDA’s ongoing National Scrapie Surveillance Program called Regulatory Slaughter Surveillance, where brains from  adult sheep and goat are examined.

In a July 31 press release, the USDA said final diagnostic results and genotype analysis were completed by the National Veterinary Services Laboratories, with confirmatory testing indicating classical scrapie.

Scrapie is a fatal, degenerative disease that affects the central nervous system of sheep and goats. It’s believed to be caused by an abnormal protein, or prion.

Prior to this confirmation, the last case of classical scrapie was detected in a sheep sampled at slaughter in January 2021. This sheep was from a flock in Wisconsin and was attributed the flock of origin to Arkansas; it was not completely traceable due to lack of identification to flock of origin, according to the USDA.

The United States was positioned to meet World Organization of Animal Health’s 7‑year benchmark for self‑declared scrapie freedom in January 2028. This confirmed detection could reset that timeline and may push the earliest possible date for national scrapie‑free status to approximately 2033.

Scrapie is hard to detect as its believed to be spread primarily from mother to offspring (or other lambs) via contact with afterbirth or milk/colostrum. But it can take 2 to 5 years for an animal to show signs of disease, and current diagnostic tests require brain or lymphoid tissue.

Animals typically live 1 to 6 months after they begin to show signs, but death is inevitable. There is no treatment or preventative for scrapie. The scrapie agent is also difficult to decontaminate as it’s resistant to most disinfectants as well as heat and radiation treatment.

This is why locating the flock of origin and engaging in strong animal identification practices nationwide is so important, the American Sheep Industry Association said.

APHIS and state animal health officials have initiated an epidemiological investigation to determine the flock of origin, but the affected animal in the Oregon case did not have ear tags, which may limit traceability. To support the investigation, NVSL will conduct tissue‑matching and parentage testing on the affected sheep and two additional animals that came with it.

“The importance of official scrapie tags cannot be understated,” said Cindy Wolf, DVM and American Sheep Industry Association’s Animal Health Council co-chair.

Scrapie tags are ear tags required by the National Scrapie Eradication Program on most sheep and goats if they leave their farm of origin and change ownership.

“These tags have made trace back to the flock of origin possible in order to stop further spread,” added Roselle Busch, DVM and ASI Animal Health Council co-chair.

APHIS said it expects minimal impact on trade. Most countries restrict live animal exports only from affected flocks or premises, and products such as wool remain unaffected.
