Ocean off Newfoundland currently has greatest temperature increase in North America, says researcher

An ocean climate expert says the waters off the coast of Newfoundland are currently the furthest above normal temperatures in North America, which could impact the climate over the summer and fall if the pattern continues.

Frdric Cyr, an ocean researchscientist with the federal Department of Fisheries and Oceans, said water surface temperatures are increasingfollowing a week of heat and humidity a trend being seen across the North Atlantic.

"The temperature is at record high, never seen before. Like, way beyond natural fluctuation. For a climate scientist it's quite fascinating, but a bit worrisome as well," CyrsaidFriday.

"The situation has changed in July, partly driven by the nice weather. And yeah, right now the Grand Banks are the warmest spot in the North Atlantic. It's more than five degrees Celsius on the Grand Bank warmer than normal."

Cyr said a record of 20 C was reached last summer. He said surface temperatures rangingfrom 18 to 20 C are abnormally warm.

"Right now we're trending way above, but again it could be short-lived," he said."It really depends on what's going to happen over the next months. But definitely if the summer continues like that, we will reach possibly a new record this year."

Sustained warm surface temperatures can impact weather patterns, as inhurricane season.

"If the water continues to be so warm, then yeah, then at the end of the season we should be worried for potential storms. The thing is that if a storm comes this way, then it will have energy to pump from in the ocean," he said.

It's too early to tell what kind of impact current temperatures willhave on weather events like hurricanes, said Cyr, buttemperatures have fluctuated this year.

For example, he said waters off Newfoundland were cooler than average in May, likely due to a spring full of rain and fog on the Avalon Peninsula.
