Just how sensitive is the climate to increased carbon dioxide? Scientists are narrowing in on the answer – The Conversation UK
New study shows low levels of future global warming are far less likely than previously thought. Very high warming is also slightly less likely.
At the dawn of the industrial revolution, the Earths atmosphere contained 278 parts of CO per million. Today, after more than two and a half centuries of fossil fuel use, that figure is around 414 parts per million (ppm). If the build-up of CO continues at current rates, by 2060 it will have passed 560 ppm more than double the level of pre-industrial times.
Exactly how the climate will respond to all this extra CO is one of the central questions in climate science. Just how much will the clima…
