Seeing is believing. If you want to realize that climate change is real, that it's happening now, it can help to live on a coast. That's where you'll find the most mobile of climate migrants, marine life - fish, marine mammals, and marine birds.
As equatorial and tropical waters heat up, marine species are migrating poleward. Some are species that we've always had in small numbers, their ranks suddenly swollen with the arrival of newcomers. Others, such as the humpback whales, are species that had been lost due to earlier predation. It's good to see them back in significant numbers.
Many of these species migrate in pursuit of their prey fish, mainly herring and sardines, which are also moving poleward into cooler waters.
The latest newcomers are bottlenose dolphins and false killer whales found swimming together in what seems to be a mixed pod off the west coast of Vancouver Island.
"To see the two species traveling together and interacting was quite special and rare," researcher Luke Halpin says in a statement.
"It is known that common bottlenose dolphins and false killer whales seek each other out and interact, but the purpose of the interactions is unclear.”
“Since 2014 I have documented several warm-water species: common bottlenose dolphins, a swordfish and a loggerhead turtle in British Columbian waters," Halpin says.
"With marine waters increasingly warming up we can expect to see more typically warm-water species in the northeastern Pacific.”
