Levels of heat-trapping greenhouse gases in the atmosphere have reached another new record high, according to the World Meteorological Organization (WMO). There is no sign of a reversal in this trend, which is driving long-term climate change, sea level rise, ocean acidification and more extreme weather.
This week, the Special Observing Period in the Antarctic starts. For three months, weather services and international scientists will increase the number of atmospheric and sea-ice observations from different Antarctic land stations, during terrestrial field expeditions and aboard research vessels in the Southern Ocean.
In the new contribution to Polar Prediction Matters, two forecasters from Environment and Climate Change Canada (ECCC) report on automated prediction products to help forecasting blizzards in the Canadian Arctic.

CryoSat-2 satellite sea-ice thickness estimates have been assimilated within the Met Office’s Global Seasonal (GloSea) coupled ensemble prediction system, which leads to a significant improvement in the skill of September Arctic sea-ice predictions made from May.
Researchers at the Alfred Wegener Institute (Germany) assessed for the first time the skill of state‐of‐the‐art forecast systems, using a new verification metric that quantifies the accuracy of the ice edge position.
We are seeking a senior research associate to carry out atmospheric modelling on the impacts of surface exchange processes over sea ice. You will work with a numerical weather prediction model to test parameterization schemes for surface exchange over sea ice and their impact on weather and climate locally and globally. You will be a key researcher within an exciting new project that will make use of existing and new research vessel and aircraft observations of the atmospheric boundary layer.
A suite of atmospheric model experiments was carried out by researchers at the Alfred Wegener Institute in the frame of the APPLICATE project to study the impacts of the Arctic troposphere on the midlatitude atmospheric circulation and climate variability.
