Heatwave trends accelerate worldwide

(University of New South Wales) The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950’s. The research published in Nature Communications has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons. As expected, that number is also on the rise.

Twenty-year study tracks a sparrow song that went ‘viral

With the help of citizen scientists, researchers have tracked how one rare sparrow song went ”viral” across Canada, traveling over 3,000 kilometers between 2000 and 2019 and wiping out a historic song ending. The study reports that white-throated sparrows from British Columbia to Ontario have ditched their traditional three-note-ending song in favor of a unique two-note-ending variant — although researchers don’t know what made the new song so compelling.
