Bickel)this year from Stroeve and York looked at sea ice levels, that 180-day hunger threshold and climate simulations based on different levels of carbon pollution. The researchers found that once Earth warms another 1.3 or 1.4 degrees Celsius (2.3 to 2.5 degrees Fahrenheit) from now, the polar bears likely will cross that point of no return. Bears will be too hungry and this population likely dies out.

that look at current efforts to curb carbon dioxide emissions project warming of about 1.5 degrees to 1.7 degrees Celsius (2.7 to 3.1 degrees Fahrenheit) from now by the end of the century.“The populations will definitely not make it,” Stroeve said.

There’s about 4,500 polar bears in the three Hudson Bay populations and 55,000 beluga whales. Together, that’s more than 141 million pounds of fat large mammals. That seems huge, but those white beasts are losing a battle to an even larger weight: the amount of
