People are increasingly concerned about climate change due to its widespread impacts, including rising temperatures, extreme weather events, and ecosystem disruptions. Addressing these challenges requires urgent global action to reduce greenhouse gas emissions and adapt to a rapidly changing environment.

Little is known about the climate change of wind systems in the mesosphere and lower thermosphere at the edge of space at altitudes from 70–110 km. Meteor radars represent a well-accepted remote sensing technique to measure winds at these altitudes. Here we present a state-of-the-art climatological interhemispheric comparison using continuous and long-lasting observations from worldwide distributed meteor radars from the Arctic to the Antarctic and sophisticated general circulation models.
