One geoengineering proposal involves painting buildings white on
a massive scale, to reflect sunlight [LONDON] Decisions on
whether and how to use massive technical solutions known as
'geoengineering' to mitigate or reverse climate change must
involve developing countries, a session on geoengineering
governance at the Planet Under Pressure conference agreed
yesterday (28 March). Geoengineering proposals have included
reflecting sunlight away from the Earth by spraying ocean water
into clouds or loading the stratosphere with sulphate aerosols,
bioengineering crops to be paler and more reflective of
sunlight, managing solar radiation and removing carbon dioxide
from the atmosphere. Although geoengineering research groups are
emerging in Africa, China and India, the controversial
discipline is dominated by a small number of organisations in
North America and Europe, the meeting heard. "It's very
important that people with knowledge and understanding of
science and the climate change challenges faced by developin
