Are We Really Past the Point of No Return on Climate? Scientists Respond To Controversial New Study

A controversial new climate study has found that, even if greenhouse gas emissions were halted tomorrow, it might not be enough to stop temperatures from continuing to rise. 

The study, published in Scientific Reports Thursday, was conducted by two researchers at the BI Norwegian Business School. They used the ESCIMO climate model to determine that, even if emissions ceased tomorrow, the permafrost would continue to thaw for hundreds of years.

"According to our models, humanity is beyond the point-of-no-return when it comes to halting the melting of permafrost using greenhouse gas cuts as the single tool," lead author and professor emeritus of climate strategy Jorgen Randers told AFP. "If we want to stop this melting process we must do something in addition – for example, suck CO2 out of the atmosphere and store it underground, and make Earth's surface brighter."
