Climate change poses new and little understood challenge to the bears. There is evidence suggesting that bears are denning later, and staying on the landscape longer in the fall when unintended shooting by hunters are most common. Most importantly, a changing climate can also impact food resources for grizzlies.

For example, whitebark pine seeds are major food source for grizzly bears in the Yellowstone Ecosystem. Blister rust (an exotic species) and mountain pine beetle infections, exacerbated by climate change, are major threats to changing food conditions. Grizzly bears that choose to adapt to human-generated food resources often die as a result. What a grizzly bear’s environment and diet will look like in the face of climate change is still uncertain, and as habitats are altered we will have to continually assess the impacts to grizzly bears.

Changes in climate and extreme weather events have already begun to affect biodiversity across the globe and mostly what negatively affect not only grizzly bears but also impacts on wildlife. Humans and wild animals face new challenges for survival because of climate change. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. Sea levels are rising and oceans are becoming warmer. Longer, more intense droughts threaten crops, wildlife and freshwater supplies. From polar bears in the Arctic to marine turtles off the coast of Africa, our planet’s diversity of life is at risk from the changing climate.
Solution to this issue:
1.) Advance policies to fight climate change
2.) Engage with business to reduce carbon emissions
3.) Help people and nature adapt to a changing climate
