Everybody knows that the sea-ice in the Arctic is melting. Now a new study shows just how severly this melting is proceeding.
2007 was the year where Arctic sea-ice gave us a scary example for what we have found true since then: that the IPCC report was not just describing true changes in our climatic system, but that these changes are often faster than some of the worst case scenarios of the climate models. The extent of the Arctic sea-ice had shrunk so much, that for the first time in human memory the Northwest passage was navigable.
If melting continues like that, then – so scientists fear – the summer Arctic sea-ice could be completely gone within 20 to 30 years; the tipping point for a complete melting of Arctic sea-ice in the summer even might have been crossed already.
