The rise and fall of acid rain is a global experiment whose results are preserved in the geologic record and in Greenland ice sheet samples, which discovered a link between air acidity and how…

Vapor losses to the walls of laboratory chambers haven't been properly factored in, according to a new PNAS paper, and that has caused researchers to underestimate the formation of secondary organic…

Arid areas are among the biggest (non-ocean) ecosystems we have and it turns out they take up higher levels of carbon as levels of carbon dioxide increase in the atmosphere. The findings give…

Scientific uncertainly prevents definitive solutions (beyond putting a stop to the world and leaving poor people to a future with no food, water or air conditioning) but the stance that the issue is…
