* Increased food availability: As the climate warms, the ranges of some of otters' prey species, such as fish, amphibians, and crustaceans, are shifting northward. This means that otters in many areas will have access to more food than they did in the past.
* Reduced ice cover: Otters rely on ice to build their dens and to travel between different areas of their habitat. In some areas, climate change is causing ice cover to decline, which could make it more difficult for otters to survive. However, in other areas, climate change is causing ice cover to increase, which could benefit otters by providing them with more habitat.
Whales:
* Increased food availability: As the climate warms, the oceans are becoming more stratified, which means that there is more warm water at the surface and cold water at the bottom. This stratification can lead to increased productivity in the ocean, which means that there is more food available for whales.
* Reduced sea ice: Some species of whales, such as the bowhead whale, rely on sea ice for breeding and feeding. In some areas, climate change is causing sea ice to decline, which could make it more difficult for these whales to survive. However, in other areas, climate change is causing sea ice to increase, which could benefit these whales by providing them with more habitat.
Overall, the effects of climate change on otters and whales are complex and vary depending on the species and the specific location. In some cases, climate change may benefit these animals by providing them with more food and habitat. In other cases, climate change may harm these animals by making it more difficult for them to survive.
