Forcing Change

[Prof. Eliot Jacobson @EliotJacobson]

Breaking News!

CERES just released the "Earth Energy" data for November, 2025, and there was a new record low for the 36-month running average for Earth albedo, now down to 28.682%.

August 2025 was another record shattering hot month for the North Pacific Ocean.

@ECMWF's ERA5 shows both a record high Sea Surface Temperature and a record high Anomaly for the mid-latitude region:

Something weird is going on with global SSTs.

[Jeff Berardelli @WeatherProf]

Since the dawn of the industrial revolution, a couple of hundred years ago, greenhouse gas forcing - mainly from burning fossil fuels - has more than doubled. Meaning that the ability of the atmosphere to trap heat has significantly increased. Thanks @LeonSimons8 for the graphic!

[Leon Simons 🌍 @LeonSimons8]

Many would rather be 'precisely wrong than roughly right'.

I think that's completely wrong!

We shouldn't ignore tropospheric ozone, which produces a FORCING of about 0.51 W/m².

Equal to about 16 years, or 640 billion tonnes of CO₂ emissions.

🚨Global Warming Has Accelerated 🌡📈

This shows how much Earth's Energy Imbalance has increased.

The rate of global heat uptake is now likely more than double what was between 1971-2008.

@NASA CERES satellite data puts the average of the past four years at +1.4 W/m²!

[Leon Simons 🌍 @LeonSimons8]

Let's not feel lucky/hopeful and gamble the future on climate change being not so bad.

That would be rather stupid.

If it's only your own bank account you're gambling with, it's (relatively) fine.

The Mediterranean will be faced with extreme warming and climate change THIS decade.

IPCC provides a false sense of security.

No one seems to give a sh*t.

Gross negligence!

[Leon Simons 🌍 @LeonSimons8]

There's very little reason to assume 30 year linear warming extrapolation.

Emissions, forcings, Earth's Energy Imbalance and (especially variability corrected) temperature observations all indicate acceleration of global warming.

We should prepare for reaching +2.0°C soon!

Did cleaner air make Hurricane Milton stronger?

There is a strong correlation (R² = 0.62) between the regional decrease in sulphur emissions from shipping and increase in Sea Surface Temperatures.

Higher Sea Surface Temperatures strengthen hurricanes.

This great article by @ZombiePanther2 still resonates.

I just want to add that there is a lot of denial and self censoring by climate scientists and journalists too.

"When you express alarm about how rapidly the climate is warming, the “calm down” crowd will correct you ..."

Here is my scientific update @TEDTalks of the state of the Planet. The planet is changing faster than expected, hitting harder on people across the world. We must admit we have underestimated risks. Tipping points are approaching fast. Window open? Yes https://t.co/0Vbn9DdjOB

[Makiko Sato @MakikoSato6]

El Nino is gone. SST in 20-60N is getting much warmer, probably due to the reduction of the aerosols from ships. There is seasonal variations, so the 12-month running means tie now, but it will become clear in a few months.

[Leon Simons 🌍 @LeonSimons8]

@ryankatzrosene @flowinguphill @Lijing_Cheng Deirdre doesn't understand that this means the rate is increasing...

+0.36 W/m²/decade means the rate of OHC increase increased.

It's right there in the abstract.

[Leon Simons 🌍 @LeonSimons8]

🌍📈
The most outspoken skeptic on this soapboX finally acknowledges that the rate of ocean warming (which takes up ~90% of Earth’s Energy Imbalance) has accelerated.

Not sure why he feels the need to accompany this with a strawmann on the effects of shipping aerosol changes...

If the AMOC shuts down, winter in Bergen, Norway will be about 30°C colder!..

[Makiko Sato @MakikoSato6]

Monthly global mean ocean temperature had maximum anomaly in August 2023 and has been decreasing.
I also checked the global ocean T distribution difference between 2015/16 and 2023/24 El Nino periods. Northern Atlantic is much warmer, Pacific is a mixture. [GISS data]

@Race2Extinct @MarkTrewick1 @NBPTROCKS @janevandis @DrJamesHansen @ClimateOfGavin @KevinClimate @climate_ice @PCarterClimate We need many different fields working together if we want to figure this out.

I work with some of the greatest climate physicists in the world.

One thing that makes them so great is that they are fully aware of the fact that they don't have all the answers themselves.
