Migratory Change in our Oceans

This Earth Day, consider how marine life is faring with warming ocean temperatures.

From the David Suzuki Foundation:

“Short-term oceanographic events, such as El Niño and the Pacific ‘blob’ — an enormous area of unusually warm water in the North Pacific — demonstrate that while oceans may be relatively stable, they aren’t immune to temperature shifts. These phenomena explain the appearance of unexpected species off B.C.’s coast over the past winter, including a Guadalupe fur seal, green sea turtle and Risso’s dolphins. Higher water temperatures are also changing the relative concentrations of microscopic, occasionally toxic algae.

“While these marine oddities don’t necessarily indicate a full-scale ecosystem shift, they may be signs of what to expect as the planet warms. Shorter-term phenomena correspond with longer-term oceanographic changes around the world. These changes promise to fundamentally alter the cast of characters in marine ecosystems before we’ve had the opportunity to adequately study them. …

“We can help marine life by reducing greenhouse gas emissions to keep global average temperature increases below the 1.5 C goal set out in the December Paris Agreement. Well-monitored fisheries, like those in British Columbia, will become essential data-collection points for understanding shifting marine environments. Although it’s difficult to reverse temperature and other oceanographic changes that climate change has already set in motion, we may be able to lessen the impact through habitat protection, strong fisheries management and robust scientific monitoring.”
