Un colega de EEUU me dijo hace unos 10 años que para él las COP eran un termómetro geopolítico y, por desgracia, poco más. En su momento me ofendía, ahora veo que es una visión pragmática y bastante útil: Ayuda a no frustrarse, a pensar más claramente y a planificar y a actuar mejor. Ayuda a seguir.
El resultado de la COP30 es un fracaso sin paliativos al volver a no mencionar el abandono de los combustibles fósiles en su declaración final. Ahora bien, las COP solo muestran la relación de fuerzas geopolíticas actual y el momento crítico en que se encuentra la descarbonización global.

Fair point. The effect of removing coffee from coffee drinkers is plausibly different from getting people to start drinking coffee.
Sorry @erictopol.bsky.social it doesn't. All participants were normal coffee drinkers. Therefore, the coffee-drinker arm is the Control arm. The intervention of going cold turkey increased the hazard of AF by 64% (100/0.61). The whole report is written from the wrong perspective.

Can that happen? Yes, but only in severely immunocomprmised people.
