The temperature of the Arctic matters to the entire world: it helps to keep the global climate fairly cool. Scientists now say that by 2035 there could be an end to Arctic sea ice. The northern polar ocean’s sea ice is a crucial element in the Earth system: because it is highly reflective, it sends solar radiation back out into space. Once it’s melted, there’s no longer any protection for the darker water and rock beneath, and nothing to prevent them absorbing the incoming heat.

The Planet Earth-observation company has just released new imagery of the broken Milne Ice Shelf in the Arctic.

By 3 August, this berg, or “ice island”, had itself ruptured in two, with both segments then seen to drift out into the Arctic Ocean.
