The new normal of global warming: Ice loss labelled as ‘extreme’ 10 years ago is now considered common place

  • In March, the Arctic Ocean recorded a low maximum extent
  • Rapid ice loss continued through May, and is now greater than average
  • Nasa says it is now ‘used to these kinds of low levels of sea ice’
  • They are designing a laser system to measure ice thickness from space

In March, the Arctic Ocean and surrounding seas recorded a low maximum extent, with rapid ice loss continuing through May.

While this rate of ice loss would have been considered extreme 10 years ago, Nasa now says it’s ‘kind of used to these low levels of sea ice’ and it should be considered the ‘new normal.’

The space agency is now preparing a new method to measure the thickness of sea ice, in the hopes of better understanding the changes in the Arctic.
