Although commercial whaling no longer represents a threat, climate change and its impact on krill (shrimp-like crustaceans), blue whales' major prey, makes this cetacean particularly vulnerable. Accessibility links Skip to article Together we can make the world's oceans safe for whales. 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. “One impact climate change could have is [to] … Climate change is one of the biggest threats facing whales and dolphins today. The climate is changing fast: so fast that some whale and dolphin populations may not have time to adapt. For example, although saving whales will not fully mitigate the impacts of climate change, it should be part of a comprehensive, global strategy to reduce greenhouse gas emissions. Dwindling whale populations can lead to an increase in greenhouse gases, and an increase in greenhouse gases can decrease the whale population. The whales eat several tonnes a …
Warmer waters are killing off the supply of krill, the small crustaceans that are whales' main food source in their Arctic feeding grounds. Climate change may also impact the areas of the oceans in which whales live, including migration patterns. Blue whales can also be harmed by ship strikes and by becoming entangled in fishing gear. 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. But if the number of whales dwindles and sightings become rarer, all of that could change. Whales in the Southern Ocean face the twin threat of a shortage of food and a loss of hunting grounds because of global warming, a new report warns. A study published in 2010 estimated that eight types of baleen whales, including blue, humpback, and minke whales, collectively shuttle nearly 30,000 tons of … Climate change, depletion in the ozone layer and the related rise in UV radiation may also lead to a fall in the population of krill, a primary food source for many marine species. The climate is changing fast: so fast that some whale and dolphin populations may not have time to adapt. "Whales are highly mobile creatures, so if …
