Rapid summer warming in Greenland since the early 1990s is much greater than global warming over the same period. This Arctic amplification may well have consequences for the behaviour of the northern hemisphere polar jet stream: a giant river of airflow in the atmosphere which is driven by thermal contrast between tropical and polar air masses.
