Weatherwatch: global wind speeds weakening over land

Studies show slowdown of up to 25%, while speeds over oceans are unaffected or fasterAcross the world’s land masses, measured wind speeds have been mysteriously weakening for the past 50 or so years, in some regions slowing down by as much as 25%. Several studies have come to the same conclusion, using wind observations from weather stations across the world.
Strangely, the slowdown seems to be happening largely over land. Over the oceans the phenomenon is less pronounced, with some areas
