Atlantic Canada facing big chill

I hate it when this happens
Some scientists are cautioning that global warming could mean colder weather for Atlantic Canada.

Melting Arctic ice may cause cooler water to drift south and change the climate of the eastern provinces in a different way than many people would expect, said Ken Drinkwater, who worked for three decades at the Bedford Institute of Oceanography before moving to the Institute of Marine Research in Norway five years ago.

Daniel Duplisea, a scientist from Quebec who’s also attending the conference, said the colder water flowing southward from the melted Arctic ice could "for sure" result in a cooler climate on the East Coast.

"It’s not even throughout the globe, what will happen with global warming," said Mr. Duplisea, who works with Fisheries and Oceans Canada.

"In some areas, there will be less rain. In some areas, there will be more rain. In some areas, there will be ice melting and getting colder, and other areas it will be just warmer."

An influx of colder water farther south could upset ecosystems, resulting in smaller fish and causing species that prefer warmer water to move.

"Cold water means slower growth," he said.

This would be disastrous for coastal communities dependant upon the industry, such as in northern Quebec where they fish snow crab, he said.
