Europe in 2023 This section provides an overview of Europe in 2023, compared to the long-term trends of variables across the climate system. Spotlight sections provide a detailed look at key events during the year, and a discussion of climate policy and action with a focus on human health.

Despite substantial progress in understanding global biodiversity loss, major taxonomic and geographic knowledge gaps remain. Decision makers often rely on expert judgement to fill knowledge gaps, but are rarely able to engage with sufficiently large and diverse groups of specialists. To improve understanding of the perspectives of thousands of biodiversity experts worldwide, we conducted a survey and asked experts to focus on the taxa and freshwater, terrestrial, or marine ecosystem with which they are most familiar. We found several points of overwhelming consensus (for instance, multiple drivers of biodiversity loss interact synergistically) and important demographic and geographic differences in specialists’ perspectives and estimates.

Le jeudi 08 juin sera célébré la Journée mondiale de l'océan.

A cette occasion, l'OiEau a souhaité mettre à votre disposition un document synthétique présentant, en quelques chiffres significatifs, l'impact de l'activité humaine sur ces vastes étendues d'eau salée qui couvrent une grande partie de la surface du globe terrestre.
