Tropical dams emit considerably more greenhouse gas emissions than their temperate counterparts yet are being treated as a solution to climate change, warns a report published in Nature Climate Change.
The problem, argue Philip Fearnside and Salvador Pueyo, is the result of errors in calculations by energy companies.
Only 33% of survey respondents said they worry "a great deal" about global warming and rainforest loss, while 55% said they're very concerned about pollution of drinking water...."We see a huge gap between Quebec, where almost a majority are worried about global warming to a great extent, versus Ontario, Alberta, and British Columbia where the worry is not as great," he said.
Coletto said the numbers should alter the debate over oilsands development, which environmental activists have attacked because of its greenhouse gas emissions.
"You're not going to win the argument if you keep plugging away at climate change," Coletto said.
