This new research could shape how we tackle the climate crisis. "The most crucial thing plankton can help us understand, however, is likely to be how the climate crisis is affecting our oceans. The shifting distribution of plankton is a measurable effect of rising sea temperatures. By studying samples over 30 years, Ostle has found that plankton living in colder waters have significantly smaller areas where they can thrive. Meanwhile, plankton living in warmer waters are moving towards cooler conditions in the poles."
