Preliminary data suggests that the global average increase in atmospheric CO2 concentration in 2024 will be a record.
Not just a little record, but 25% higher than the previous record.
(This is the global average, as opposed to Moana Loa)

Finally, we will need better ways to access all the information - for once this might be a task for artificial intelligence might be able to provide an answer (not just hype).

Such an approach could give new relevance to the information produced by multiple processes that currently get little consideration beyond the development of a few lines in conclusions or decisions that few read. It could also help to put some order and ensure better follow-up to the action agenda.

Knowledge is the most powerful tool humanity has ever developed, it gives us the ability to understand what is happening around us and to take decisions on our future. Reactionary forces have always tried stop knowledge being developed and shared. Strength to you and all the others under attack.

None of this will be easy, but in the face of deliberate and active efforts to stop and slow down the climate transition, we need to learn from what works, and avoid what does not, in national and international contexts.

Third, we need to put some order into the mutlitude of initiatives launched by successive COP presidencies - some of them can make a huge difference, but others are little more than pure communication.

Second, the multilateral climate process needs to deliver concrete support to action. Of course, we will still need to negotiate to agree ways forward on some points, but we must stop negotiating everything - that just plays into the hands of those who want to slow things down.

First, we need to develop climate policies that respond to peoples' hopes and expectations - cutting emissions, managing the transtion do not give them hope - we can build policies that offer a vision of their personal growth and the future for their children.

Itโs tempting to despair, but there are some reasons to remain positive, and above all to strengthen the fight for climate action. But if we are going to succeed, we need to avoid past mistakes and get a clearer idea of what works, and what doesnโt.

Meanwhile, major oil companies are abandoning any plans to diversify their investments and returning to what they know best, producing more oil and gas. Banks and other financial institutions are backing out of agreements to transform their investments.

Other countries profess their continued support for climate action, but in the face of mounting opposition many are increasingly tempted to slow down implementation or water down their domestic climate policies, and budget constraints are leading them to cut their development assistance in turn.

I have a new paper in Dialogues on Climate Change exploring climate outcomes under current policies. I find that we are likely headed toward 2.7C by 2100 (with uncertainties from 1.9C to 3.7C), and that high end emissions scenarios have become much less likely.

Finally, the order provides for the US withdrawal to be effective immediately. That is a unilateral reading of the provision that requires a year to take effect. But that also means that the US cannot claim the right to slow down decision-making anymore.

Overall ambition is unlikely to be as high as is needed, but the incoming Brazilian COP30 presidency, along with the UN Secretary General, can use their responsibilities to push hard for stronger implementation and collaboration.

The costs of key clean energy technologies have fallen dramatically and continue to fall, whilst climate impacts will unfortunately continue to grow. Climate action remains the right policy for the rest of the world.
