Dryness cancels climate-change warmth that would help boreal forest growth:study
By Bob Weber
A new study suggests drier weather will likely eliminate any advantage for Canada's boreal forest from higher temperatures caused by climate change.
Scientists had predicted that warmer conditions and a higher level of carbon dioxide, which plants breathe in, would promote growth.
And Martin Girardin of the Canadian Forest Service said some parts of the vast band of green that stretches across the northern provinces are expanding.
