Changes in sea temperature, freshening of seawater, acidification, rises in sea levels, the loss of icy polar habitats and the decline of food sources are just some of the many dangers which climate change poses for whales and dolphins.
Climate change is expected to be the main cause of mass extinctions in the 21st century and whales and dolphins are NOT immune. The rapid warming of the planet is leading to a loss of habitat for whales and dolphins and greater competition for a diminishing amount of prey species. It is affecting the timing and ranges of their migration, their distribution and even their ability to reproduce. Unless radical actions are taken, some whale and dolphin populations may not be able to adapt quickly enough to survive.
