Humpback whales are marine mammals that swim long distances between cold and warm waters every year to feed and have babies (calves), but rising ocean temperatures could make their breeding and calving grounds too warm. This article explains how we studied these changes by creating detailed maps predicting ocean temperatures in the future. We discovered that many humpback whale breeding areas could become too hot by the year 2100 if we do not make changes now. Whales are important for the health of our planet because they recycle nutrients and store carbon in the ocean. By switching to clean energy and taking care of the environment, we can protect humpback whales and their ocean home. This is a call to action for kids, parents, and teachers to learn about climate change and how to make a difference.
