⚡ Power prices have split across Europe since the US-Iran conflict. Prices have surged in gas-reliant markets with interconnectors at capacity. Renewable-rich regions have seen the lowest prices - like sunny Spain and Portugal and hydro-powered Sweden.

Today’s climate models aren’t sufficiently realistic to predict something as complex as climate change. Some scientists argue that they might never be sufficiently accurate to make multi-decadal, local climate predictions. If so, how can we make good decisions despite the inevitable uncertainty?

Democratic or Republican Backsliding? Lo que pierde la política comparada al ignorar lo republicano - 56:4 - LASA Forum
La república, lo republicano y el republicanismo desaparecieron de la política comparada. Lo cual es peculiar cuando lo contrastamos con otras disciplinas pertenecientes a lo que podríamos llamar la genérica familia de la reflexión política. En teoría política, por ejemplo, el republicanismo ha sido una de las categorías más importantes en los debates contemporáneos. Lo podemos ver en los trabajos de autores como Quentin Skinner (1998), Philippe Petit (2012) o de Roberto Gargarella (2021) en América latina. Algo similar ocurre si pensamos en la historiografía política latinoamericana, en la cual los trabajos de Hilda Sabato (2021) en la Argentina, Carmen McEvoy (1997) en el Perú, Valeria Coronel (2022) en Ecuador, Marixa Lasso en Panamá (2021), o José Antonio Aguilar y Rafael Rojas (2002) en México, por poner unos pocos ejemplos, han echado mano del republicanismo y sus variantes para observar o reinterpretar las historias nacionales y continentales.[1]

The anxieties that fuel the far-right obsession with IQ metrics and autism gesture to eugenic tropes. These are not good-faith contentions on public health science, but a fixation with narrow and reified versions of what intelligence and normality are.
