While large swathes of the planet are warmer than normal this March, there are some exceptions. One of those exceptions being Antarctica and Greenland where it’s been colder than normal. Helped by a +AAO (Antarctic Oscillation) in the south and +AO/NAO in the north, the coldest air in both hemisphere’s have been allowed to bottle […]

It’s been a tough summer across Australia but the extremes have turned from intense heat to intense rainfall. An unprecedented rainfall event has caused extreme flooding to coastal communities some 840 miles north of Brisbane.

It would seem summers have been on a cooling trend over Greenland in recent summers. In 2017, a new July record low of -33C was set at Summit. Thanks to a strong +NAO last summer, 2018 has been the coolest summer for Greenland in 20 years. Frequent snowfall increased the ‘surface mass budget’ or SMB […]
