A "warm blob" of water — which originated in the Gulf of Alaska — is moving south along the Pacific Coast, and scientists are warning it could hurt marine life in B.C.
"Probably I think is fair to say it's unprecedented in terms of the oceanography," Dick Beamish, a retired scientist with Fisheries and Oceans Canada, told The Early Edition's Rick Cluff.
The blob is up to 3 C warmer than average temperatures, which Beamish said will be a significant increase to fish like salmon.
"It sure makes a difference to animals that don't regulate their body temperature, so this is major event."
- Chinook salmon could be wiped out by 2100, new study claims
- Sea life relocating fast in response to climate change
- Last decade warmest on record, says UN report
Beamish said there is no question it will have an impact on marine life, but said it will take a long time to know the full impact.
"The effect is through the food chain, and so because it's through the food chain, most likely you would see that through juvenile fish survival and then you don't see the consequences of the changes in juvenile survival for a few years," he said.
"It's not so much that you're going to see something instantly. We are seeing, according to the report, mortality of birds and certainly some effect on marine mammals, but in terms of fish — let's say particularly salmon — it's not so easy to forecast what is going to happen."
