Cette cité dans le Worcestershire est devenue la première ville du Royaume-Uni où il n’est plus possible de conclure un contrat d’assurance contre les inondations. Les commerçants doivent absorber les coûts ou fermer boutique.

The economic case for methane action is clear.

- Global methane abatement yields large net global economic benefits.
- The benefit-cost ratio of methane action is at least 3—rising to more than 6 when health cobenefits are included.

www.science.org/doi/10.1126/...
Net present value of climate benefits (market and nonmarket), air-quality cobenefits, and abatement costs under five methane abatement cost scenarios. Horizontal black lines show net benefits. The dashed line indicates the switching value threshold and available cost headroom before net present value is reduced to zero. The discount rate is 2.5%. Methane emissions and effect on global mean temperature of methane action scenarios. (Left) Methane emissions. (Right) Effect on global mean temperature. Background emissions scenario is SSP2-4.5. The shaded area is the 90% confidence interval of temperature outcomes pertaining to the central methane action scenario, based on parametric uncertainty in META sampled by 1000 Monte Carlo runs. “Methane action – high” and “Methane action – low” describe methane action scenarios resulting in high and low emissions, respectively. Specification includes tipping points.

Our new @climameter.bsky.social study shows that natural variability alone can’t explain these changes — human-caused warming is a key driver.

The thing I find so shocking about this video is not only that this person classifies himself as "samfunnsøkonom" (that is, in principle, a rare brand of economists who actually try understand people) - but also that he really seems to believe the utter nonsense he is producing.

May I note in passing that several countries currently have autocratic leaders who inflict intolerable suffering on their own citizens and the rest of the world, but the simple modification of the headquarters of one of these causes a wave of indignation that is completely disproportionate to me.

A bitter day for the fight against climate change. The decision by the International Maritime Organization (IMO) to postpone the decision on the climate protection pathway for global shipping by one year is wrong. Countries may be able to be pressured, but the planet cannot.
