Hudson Bay
Winter ice melts two to three weeks earlier than before. That makes it harder for polar bears to find food.

Kenya and Tanzania
Malaria, a deadly disease, is spreading. It’s carried by mosquitoes. And they love warmer weather.

Great Barrier Reef
Ocean water is slowly growing warmer. The heat is hurting and even killing big pieces of the world’s largest coral reef.

Antarctic Peninsula
Winter temperatures are nine degrees higher than in 1950. Sea ice has shrunk by one fifth. These changes make it much tougher for Adélie penguins to survive. Bird populations are sinking.
