Some British scientists say “geo-engineering” is needed to counter the effects of global warming and maintain world temperatures at acceptable levels, according to a report in The Sunday Times.
One proposed measure calls for massive planting of fast-growing trees, such as willows, to absorb more carbon dioxide.
Another proposal would seed clouds with ocean water to form salt crystals, which would reflect more sunlight back toward the sun and away from the Earth.
However, some critics say not enough is known about climate to manipulate it safely.
Others argue that artificial solutions focus attention away from the real problem — the need to develop more environmentally friendly economies.
