Researchers are in the search for generalisable rules and patterns in nature. Biogeographer Julia Kemppinen together with her colleagues tested if plant functional traits show similar patterns along microclimatic gradients across far-apart regions from the high-Arctic Svalbard to the sub-Antarctic Marion Island.

It is widely known that global vegetation patterns and plant properties follow major differences in climate. Yet, it has remained a mystery how well the same rules can be applied at very local scales. Are responses to the environment similar in plant communities along local temperature

It is widely known that global vegetation patterns and plant properties follow major differences in climate. Yet, it has remained a mystery how well the same rules can be applied at very local scales. Are responses to the environment similar in plant communities along local temperature gradients in Svalbard, Greenland, Fennoscandia, and Marion island? The results published in
Westerly Winds Could Intensify, Migrate Poleward with Climate Change

The most high-resolution past record of the Southern Hemisphere westerly winds has now been developed by polar climate scientists.

The study findings were published on December 9th, 2020, in the
Communications Earth and Environment journal and explain how the winds could probably strengthen and migrate poleward with the warming climate. The study offers data that will enhance the precision of models that predict the future.
The westerly winds (called the furious fifties, roaring forties and screaming sixties with respect to their latitude) are specifically strong since there is a lack of continental landmasses in the Southern Ocean to reduce their speed.
