Global whale population and migration shifts

Overview

Whale populations are experiencing significant shifts driven by conservation efforts and climate-induced migration. In Brazil, humpback whale numbers have recovered from near extinction in the early 1990s to over 30,000 individuals visiting the coast, a success attributed to sustained protection and monitoring.

In the Arctic, warming ocean temperatures and receding sea ice are causing a ‘major ecological regime shift’ in East Greenland. As previously inaccessible territories become ice-free, thousands of humpback, fin, and minke whales are migrating into these coastal areas to feed. While humpback sightings in the region were non-existent until 2006, recent estimates suggest approximately 4,000 humpbacks, 6,000 fin whales, and 6,000 minke whales visited the Greenland Sea in the summer of 2024. This influx, part of a process known as borealization, may impact local ecosystems and the regional fishing sector due to high prey consumption.
