Researchers set out path for global warming reversal

Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target.

Sound is fascinating—let’s take a closer look at how it works!
