Planting trees may help appease travellers' guilt about pumping carbon into the atmosphere.
But new research suggests it will do little to cool the planet, especially when trees are planted in Canada and other northern countries, says climatologist Alvaro Montenegro, at St. Francis Xavier University in Nova Scotia.
"There is no magic bullet" for global warming, says Montenegro, "and trees are certainly not going to be providing it."
He assessed the impact of replanting forests on crop and marginal lands with Environment Canada researcher Vivek Arora. Their study, published Sunday in Nature Geoscience, concludes "afforestation is not a substitute for reduced greenhouse-gas emissions."
