The Northern Pacific Ocean is currently smashing temperature records.

And it is reaching these levels far earlier than the current generation of climate models had expected.

A short thread 🧵

Time series of monthly Northern Pacific Ocean sea surface temperature anomalies from 1850 to August 2025 alongside multi-model expectations of the warming in this area (scenario SSP2-4.5).

NASA says solar activity is increasing after decades-long lull: "The sun is slowly waking up"

The sun has become more and more active over the last 16 years, in a turn that surprised scientists and could affect space weather, NASA said.

A challenging summer for air quality saw the highest wildfire emissions in 23 years in Europe & the UK, driven by wildfires in Iberia. CAMS data also revealed repeated episodes of transatlantic smoke, Saharan dust and ozone spikes. Read the article: atmosphere.copernicus.eu/highest-wild...

This week’s heatwave adds to a summer of relentless extremes in Spain.

A new report shows how climate change amplified the June–August heat—driving up temps, risky heat days, and the odds of dangerous conditions ⤵️

Dashboard showing summer 2025 heat in Spain. Seasonal temperature anomaly: +1.8°C. 60 days had CSI ≥2 (at least twice as likely due to climate change). 55 risky heat days (above 90th percentile), with 31 added by climate change. City breakdown: Barcelona +2.2°C, 68 CSI days, 62 risky heat days (33 added). Madrid +1.5°C, 52 CSI days, 52 risky heat days (37 added). Sevilla +0.6°C, 27 CSI days, 37 risky heat days (23 added). Valencia +1.8°C, 81 CSI days, 61 risky heat days (43 added).

It's not your imagination: Wildfire smoke in the U.S. has dramatically worsened since 2019. According to a new study, it's already killing 41,000 people a year - and it's poised to get much worse.

new from me @johnmuyskens.bsky.social and @sadbumblebee.buzz

www.washingtonpost.com/climate-envi...

Record wildfire smoke kills more people each year than car crashes. It’s about to get worse.

The past six summers have been the smokiest on record. New research shows that smoke could become the costliest consequence of climate change for Americans.

The "smoke season" is also lengthening. Between 2006 and 2019, the amount of days where average smoke concentration was over 1 microgram/m3 was about a month. In 2023, it was over 6 months 😮

EXCEPTIONAL HEAT IN CANADA

Crazy heat for the second half of September with up to 34.6C at Kamloops today (terrible forecasts again by ECC understimated by 3C/4C).

The heat will continue for the rest of the week:
This month in inner British Columbia is being ABSURDLY HOT.

🌊🌡️📈
The warming rate over the North Pacific Ocean (NPO) the past 25 years was about 1,000% higher than averaged over the preceding 150 years!

It's the rate of regional warming and the resulting climate and weather impacts that pose such a threat.

There is likely a lot more regional warming in the pipeline, as the level of Outgoing Longwave Radiation increased 2.4 W/m² less than Absorbed Solar Radiation did.

Note that the correlation between the Pacific Decadal Oscillation (PDO) and absorbed sunlight had completely flipped, starting 2020.

We've been warning about this for years and called for increased research and for urgent, precautionary adaptation and mitigation.

The more data comes in, the worse it looks.

How hot is the North Pacific?

The latest data from ECMWF for August, 2025, puts the average sea surface temperature at 6.212 standard deviations above the 1951-2000 average.

If SSTs were normally distributed (they aren't), that would be about 1-in-3.8 billion by chance.

"The central fact of global warming is that human-generated greenhouse gases trap energy that would otherwise escape into space, making the planet's average temperature go up."
