If you have one of those "Save the Whales" T-shirts in the back of your closet, now would be an appropriate time to dust it off.

Recently, there have been many reports about the endangered North Atlantic right whale's population declining. According to The Guardian, there were 482 right whales on Earth in 2010; but now, there are only about 411. The news outlet cited a new study called Rapid Climate-Driven Circulation Changes Threaten Conservation of Endangered North Atlantic Right Whales, published by The Oceanography Society. The paper's authors found that various ocean changes related to the climate crisis may be responsible for this notable decline.

North Atlantic right whales, also known as Eubalaena glacialis, reside in the ocean near Canada and the northeastern U.S. during the spring, summer, and fall. In the winter, which is their calving season, they migrate south to give birth, according to the National Oceanic and Atmospheric Administration. Not only has the right whale population declined, but so has the right whale's birth rate — over the past decade, right whales have given birth to less and less calves.
