The wide range of socio-economic scenarios in climate projections results in high uncertainty about climate change.
We compare socio-economic scenario projections to observations over 1990–2010.
Global CO2 emission intensity increased despite all major scenarios projecting a decline.
Under-projection of emission intensity raises concerns about achieving emission targets.

While the United States gears up for what is expected to be a record-breaking production year in 2018, the rest of the world remains far away from catching up to America’s runaway shale success.

Or s’agissant du climat aux Antilles l’année 2015 a été importante pour une toute autre raison que la signature de l’Accord de Paris : c’est l’année de publication d’un article de recherche tout à fait passionnant sur les ouragans dans cette région du monde.
