Detailed explanation-1: -The declines in sea ice thickness and extent, along with changes in the timing of ice melt, are putting animals that are particularly ice-dependent-such as narwhals, polar bears and walrus-at risk. By 2100, polar bears could face starvation and reproductive failure even in the far north of Canada.
Detailed explanation-2: -The Arctic is one of the ecosystems most vulnerable to the effects of climate change, as it is warming at least twice the rate of the global average and melting land ice sheets and glaciers contribute dramatically to sea level rise around the globe.
Detailed explanation-3: -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.
