LONDON - Unchecked global warming will devastate the world economy on the scale of the world wars and the Great Depression, a British government report said yesterday, as the country launched a bid to convince doubters that environmentalism and economic growth can coincide.
Prime Minister Tony Blair said unabated climate change would eventually cost the world the equivalent of between 5 percent and 20 percent of global gross domestic product each year. He called for "bold and decisive action" to cut carbon emissions and stem the worst of the temperature rise.
