Assuming easy carbon removal from the atmosphere is a high-stakes gamble, scientists say

Stanford researchers warn against placing too much emphasis on unproven methods for removing carbon dioxide from the atmosphere. Credit: Lukas Schulze/Getty ImagesThe manmade emissions fueling global warming are accumulating so quickly in the atmosphere that climate change could spiral out of control before humanity can take measures drastic enough to cool the earth’s fever, many climate scientists say. The most important way the earth’s rising temperature can be tempered is to reduce the use of fossil fuels. But scientists say another critical solution is to physically remove greenhouse gases from the atmosphere — something called “negative emissions” — so that carbon dioxide and rising temperatures could peak, and then begin to decline over time.   Many of the assumptions underlying the landmark Paris Climate Agreement rely on the idea that humans will be actively removing carbon from the atmosphere late this century because reducing emissions won’t be enough to prevent

Assuming easy carbon removal from the atmosphere is a high-stakes gamble, scientists say

With the current pace of renewable energy deployment and emissions reductions efforts, the world is unlikely to achieve the Paris Climate Agreement's goal of limiting global warming to 2 degrees ...
