Reducing the impacts of human-caused climate change through the use of bioenergy with carbon capture and storage – better known as BECCS – could have major consequences for wildlife, forests and water resources, a new study shows.

The large-scale conversion of existing land to BECCS plantations could cause global forest cover to fall by as much as 10% and biodiversity “intactness” to decline by up to 7%, the lead author tells Carbon Brief.

And the introduction of solar geoengineering could also threaten wildlife, a second study shows. The new research finds that implementing – and then not sustaining – such a technology could cause global temperatures to rebound rapidly, leaving many species unable to cope with the sharp change in conditions.
