Eating healthy food, prolongs your life, and gives major contributions to a healthy planet. This makes the food system transformation as important as the global energy transition to have a chance of prosperity and an equitable future for humanity on Earth https://t.co/ZU7MsjfJL5

Holding on to 1.5°C aligned mitigation pathways and science based targets is absolutely essential. In order to minimize overshoot, costs to investments & impacts on the global economy. And, it is doable, zero solutions are there and are winners https://t.co/xW7NGlpLTW via @ft

Global warming means hope of limiting increase to 1.5C is now ‘unrealistic’, says NBIM’s head of governance

In the coming decades, global population & GDP growth are projected to increase & ultimately accelerate common drivers underpinning the triple challenge posed by climate change, biodiversity loss & pollution. Report shows the full scale of these impacts: https://t.co/6WwYa0K3qs

Yearly wind power production. China leads the world; the US started its exponential growth some years after Europe but then caught up with the EU. Cheap wind power is now threatening fossil fuel profits, a powerful lobby with obvious undue hold over the Trump administration.

Sannolikheten för en kollaps av AMOC [systemet av havströmmar i Atlanten som reglerar havets värmeutbyte och klimatet i Sverige, Norden och världen] är nu så hög, trots osäkerhet, att det måste anses vara en oacceptabel risk. Som troligen kan undvikas. Norden måste visa ledarskap

"An economy driven by fossil fuels & extraction cannot continue without putting the planet at risk". 🚨 @jrockstrom, @PIK_climate in #Davos. The pathway to prosperity is clear: align with science, live within planetary boundaries, phase out #fossilfuels: now. ⏱️ #WEF2026

The destabilisation of the #AMOC is no longer a distant scenario - it’s a national and global security risk. In a new article in Dagens Nyheter, Iceland’s Climate Minister Jóhann Páll Jóhannsson and I outline actions to tackle this threat: https://t.co/1tfJJGNpUT (in Swedish)

“This is not the time for resignation; it’s a time of heightened urgency.” In a blog post ahead of @wef annual meeting #WEF26, PIK Director @jrockstrom and @CnobreRes (@usponline) highlight the importance of the 1.5C limit, naming four deciding factors. https://t.co/ZbRY5lmORb

Scientific consensus indicates that global warming has reached the 1.5°C threshold, requiring climate policy to shift from commitments to the rapid, science-aligned phase-out of fossil fuels.

“We are at the beginning of the end of the fossil fuel economy. The US is betting on the wrong horse.” PIK Director @jrockstrom spoke to @nytimes about how the clean energy transition is gathering speed despite the actions of the Trump administration.
nytimes.com
The president’s embrace of fossil fuels and withdrawal from the global fight against climate change will make it hard to keep warming at safe levels, scientists said.

Europe’s forests are weakening under heat, drought & pests, yet climate targets rely on them. This is dangerous says PIKs @jrockstrom because "countries can use their carbon sink from forests to say they're net zero without fully phasing out fossil fuels.” https://t.co/PP5VdAMkYp

Vast swathes of the country’s trees have been killed off by droughts and infestations, in a trend sweeping across Europe. A shift towards more biodiverse cultivation could offer answers

“The U.S. turns its back against science, against global collaboration, against any kind of action on #climatechange,” PIK Director @jrockstrom says on the U.S. pulling out of the @UNFCCC. “The world loses a lot and it is very damaging.”

U.S. President Donald Trump's withdrawal from the United Nations climate framework marks a significant escalation of anti-climate policy.

Humans have emitted 2750 gigatons of CO2 since the industrial revolution from burning fossil fuels and land use change. To put this in perspective, this is more than the (dry) mass of all living things on earth and everything humans have ever built combined:

3. Constraints drive innovation and 2035 phase-out is an effective boundary with clear incentives. The world is in the midst of the race away from ICE to electric mobility. Introducing "flexibility" creates uncertainty and slows down the unstoppable path towards future mobility

2. 5% offsetting and compensating ICE emissions with green steel does not work. The reason is that the RCB is so limited that ALL sectors need to decarbonise until 2040, both steel AND oil (domestic & abroad). Great to do both! But, not possible to offset one against the other.

1. Missing climate targets. EUs recent decision to reduce emissions by 90% by 2040 is positive but scientifically insufficient. The Remaining Carbon Budget (RCB) is essentially consumed, and 1.5°C will be breached within 5-10 years. EU must reach zero emissions sooner than 2040.

Here are the 3 reasons why the EU Commission decision to abandon 2035 end-date for the Internal combustion engine (ICE) is the wrong decision. 1 EU will miss its climate targets 2 Offsetting does not work 3 European car industry will lose in the competition & race against China
