GLOBAL TEMPERATURE 3 August 2015 17:05
Two degree climate target not possible without ‘negative emissions’, scientists warn

All of our options for keeping warming below 2C above pre-industrial temperatures now involve capturing carbon dioxide and storing it underground – a technology that doesn’t yet exist on a large scale, according to new research.

The study , published today in Nature Communications, argues that ‘negative emissions’ alone, in the absence of conventional mitigation, are unlikely to achieve the 2C goal.
