Achieving negative emissions could bridge the gap for meeting global warming targets, but could also be a dangerous distraction
CARBON CAPTURE AND STORAGE
Negative emissions may sound like the latest descent into climate-speak, but they are fast becoming a much talked about concept in the climate and energy discussion. In the second half of this century, reabsorbing and storing more CO2 from the earth's atmosphere than is created through industrial activity is increasingly referred to as a crucial weapon for successfully combating climate change. Tobias Nielsen at Lund university, Sweden, shares his thoughts on the topic. ...
