828 Years Until Global Sea Ice Melts

In 1980 Global Sea Ice was 22.8 million Sq km.

In 2018 Global Sea Ice is 21.8 million sq km

1 million sq km of melt per 38 years.

21.8 million sq km to go.

828 years

  1. Use 2014’s peak to project how much of the poles will be an icy, white wasteland in 828 years. That would be interesting.

    • OK, simple math says at the addition rate of 1.7 million km2 between 1980-2014, in another 828 years there will be another 41.4 million square km—nearly tripling the extent of today. That would not be a future anyone would want to see.

      • The funny thing about the data is there is almost no trend at all. But you are right about 2014.
