Another day, another “Arctic will be ice-free in _____ years” warning:

This one will take a while to be proven correct or incorrect:

Nobel Peace Prize winner Professor Oleg Anisimov said there is evidence that temperatures are rising four times faster in the frozen region than the rest of the planet.

This means that there will only be open water in the polar region by the 2050s, with nothing more than a few floating icebergs at the North Pole, according to the Russian academic.

Been there, done that. Many times:

In 2007, Al Gore warned that the Arctic could be ice free in the summer within five years.

Now the prediction is 40 years out, which certainly buys enough time to avoid immediate embarrassment when a shorter-term prediction fails to come to fruition.
