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.
