Geoengineering 'Not a Solution' to Sea-Level Rise
from BBC News Online
Even the most extreme geoengineering approaches will not stop sea levels from rising due to climate change, a study suggests. New research proposes that as many as 150 million people could be affected as ocean levels increases by 30cm to 70cm by the end of this century.
This could result in flooding of low-lying coastal areas, including some of the world's largest cities. The team published the study in the journal PNAS.
Scientists led by John Moore from Beijing Normal University, China, write that to combat global warming, people need to concentrate on sharply curbing greenhouse gas emissions and not rely too much on proposed geoengineering methods. "Substituting geoengineering for greenhouse emission control would be to burden future generations with enormous risk," said Svetlana Jevrejeva of the UK's National Oceanography Centre, a co-author of the study.
