🚨 None of the UN IPCC models capture what NASA satellites are seeing.

We should assume and prepare for the worst, as there is a non-zero chance of 3°C of global warming by 2050.

We better assume that it will happen and/or try to make sure that it doesn't happen.

WE WILL RUN OUT OF FOOD.

The fact we aren’t using this precious & precarious moment to rebuild our food system around need & not profit - changing what we eat, how we produce food & how we transport it - will prove our gravest & most suicidal mistake.

Monitoring changes in UK temperature

To (almost) no-one’s surprise, multiple sources of data agree on the long-term trends in UK temperatures.

I just updated this NASA CERES graph. The regional level of Absorbed Solar Radiation increased by 4.2 W/m² in 20 years!!

That's more than the global greenhouse gas forcing increase since 1750!

The 2 W/m² Net Flux increase indicates that there is a lot more regional warming in the pipeline.

This is what rapidly accelerating warming looks like.

Another off the chart datapoint:
NOAA Sea Surface Temperature data for the summer 2025.

This folks is the coolest Summer you will ever experience again

Southern Europe is frying too with Turkey setting a new record of over 50 C (122 F)
These temperatures will kill you if you stay out too long outside and if you have no air conditioning

This is an extreme level of heat.

Killing the only planet known to harbor life at ever faster rate

Little more than half a year into 2025, mankind has already hit Earth Overshoot Day, consuming resources at a rate that far outpaces the capacity to restore them.

A lot of media are covering Europe’s heatwave 🔥 but few are connecting it to the climate crisis.

Tools like the Climate Shift Index show this heatwave is up to 5x 😱 more likely because of climate change. That context matters.

Data from CERES show that from 2001 to 2023, Earth absorbed more energy than any CMIP6 model predicted.

Models with ECS < 2.5°C fail to match observed LW & SW trends (LW↓, SW↑). This means future warming may be closer to higher-sensitivity projections.

Seems important:

All ('IPCC') CMIP6 models are completely unable to reproduce what NASA satellites observed!

The rate of global warming (starting with Earth's Energy Imbalance and now surface air temperature) has more than doubled!
