The more I learn about climate change, the more I understand that ignorance is bliss…

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper is out today. 🧵

In low-income countries, most work in farming. Moving to services helps poverty reduction—but in agri-heavy economies, that shift is slow (<1pp/year). I think the fastest path is making smallholder farming more profitable. @_HannahRitchie @OurWorldInData

Did you know how much of the power generation capacity added each year world-wide was in renewables? 2022 it was 80 % 2023 it was 86 % 2024 it was 92,5 % Not because the whole world suddenly turned „woke“, but because it’s the cheapest!

The primary energy fallacy is the idea that all primary energy from fossil fuels must be replaced with equivalent amount of clean energy. BUT: Not necessary because conversion losses don’t need to be replaced. 2/3 of all primary energy is lost as waste heat.

This is Trump’s Easter message. Someone tell him - Easter is about Jesus. It is the day Christ rose from the dead. Trump-evangelicalism is a cult. You cannot serve two masters. Follow Jesus… not Trump. Christ is King. Donald Trump is not. Hallelujah!

A fantastic example of AI's impact on agriculture.

This graph highlights the urgent need for equitable resource access. If that alone doesn't inspire action, perhaps the fact that material usage has nearly doubled will? To address this, we must shift toward circularity and move away from the linear "take, make, use, lose" model.

Nature and climate are on the line. The scientific evidence for countries to address the twin crises of biodiversity loss and climate change has never been clearer, argue Razan Al Mubarak, UN Climate Change High-Level Champion COP28 @hlcchampions and I. https://t.co/MOhh28GHNG

What is a climate tipping point? Here my 60-second explanation at the New York Times Climate Forward last week. If you want to know more about the tipping point of the Atlantic Ocean circulation #AMOC, on which I've worked for over 30 years, watch this: https://t.co/13GjmmfK4v

44 experts from 15 countries issued a stark warning about the dangers of crossing an ocean circulation tipping point, in an open letter to the Nordic Council of Ministers. I had the honor to present it to the Icelandic 🇮🇸 climate minister Guðlaugur Þór Þórðarson yesterday. #AMOC

Academic ironies

The IEA's #1 flagship report, and the bible of the energy transition. So, what's new? My key takeaways...

Devastating hurricanes, heatwaves, floods, and wildfires - we are entering uncharted waters, and cannot exclude environmental chaos as the 2024 State of the Climate Report shows. Important new report out now.

Electrification is efficiency. When we electrify our energy systems coupled with clean electricity, something remarkable occurs: significant inefficiencies disappear. As a result, in a decarbonized world, our overall energy final demand will be much lower than it is today.

For the first time Patient Earth goes through a full Health Check. The verdict is clear - the patient is in critical condition. The 1st Planetary health check gives us the quantitative diagnosis required to guide the transformations for a safe landing

This changes everything📈. The Northern Hemisphere's Energy Imbalance. The most important @NASA data you've never heard about. The northern half of our planet started to absorb much more heat from the sun than it radiates to space. These are absolute values (not anomalies):

Excellent new paper: How locational price signals can help engage consumers and support the power system. ✅reduce system cost ✅reduce consumer cost ✅mobilise flexibility @DIW_Berlin https://t.co/arMZOF6aGD

Massive Warming in Russia near Arctic what will this do to permafrost Carbon storage? Will we rethink our strategies, have we ever had one or just pretend to do so.
