Canada is home to three oceans, all of which harbour thousands of fish and animals, on which many Canadians rely. But, with a warming planet, these bodies of water are rapidly changing.
A new study published in the journal Scientific Reports suggests that our oceans’ climates — existing environments with delicately balanced ecosystems — face extreme change under climate-change scenarios.

(Reuters) – A blob of warm water in the southern Pacific is fueling a decade-long megadrought in Chile, and climate change is at least partly to blame, scientists say.

Abstract
Marine ecosystems are experiencing unprecedented warming and acidification caused by anthropogenic carbon dioxide. For the global sea surface, we quantified the degree that present climates are disappearing and novel climates (without recent analogs) are emerging, spanning from 1800 through different emission scenarios to 2100. We quantified the sea surface environment based on model estimates of carbonate chemistry and temperature. Between 1800 and 2000, no gridpoints on the ocean surface were estimated to have experienced an extreme degree of global disappearance or novelty. In other words, the majority of environmental shifts since 1800 were not novel,
