Canadian Researchers Warn Of New Arctic Worries CANADA: April 4, 2008 VANCOUVER, British Columbia - Canada's massive Mackenzie Delta is feeling the impact of climate change faster than expected and could foretell of problems elsewhere in the Arctic, a Canadian researcher said on Thursday. Melting ocean ice is apparently allowing larger storm surges to flood into the delta in Canada's far north, a change that could have an impact on energy development plans for the region, said Lance Lesack, who has been tracking environmental changes in the region for more than a decade.
