Why college enrollment numbers are down. And how one solution to climate change could threaten an endangered species.Read more:May 1 is college decision day, which is the last chance students have to submit the deposit that secures their spot at the university or college of their choice. But colleges aren’t getting as many students as usual. Enrollment has shrunk more than 5 percent since 2019 — that’s a loss of nearly 1 million students.

Nearly annihilated centuries ago by whalers, right whales today face new threats from climate change. Dino Grandoni reports on how rising temperatures are driving them to new seas and how one climate solution – offshore wind turbines – could encroach on their habitat.
