Summer is getting longer, and it's happening faster than we thought

Summer weather is arriving earlier, lasting longer and packing more heat than it used to—and it's happening faster than scientists had previously measured. A new study by UBC researchers has found that between 1990 and 2023, the average summer between the tropics and the polar circles grew about six days longer per decade. That's up from roughly four days per decade found in past research investigations up until the early 2010s.
