What to know about Summer is getting longer, and it's happening faster than we thought

A study by UBC researchers found that summers in the tropics and polar regions have lengthened by about six days per decade since 1990, with significant impacts on ecosystems, agriculture, and human systems. The research highlights accelerated seasonal transitions and rising cumulative heat, urging reconsideration of climate models and planning assumptions.

What happened

Summer is getting longer, and it's happening faster than we thought Gaby Clark scientific editor Robert Egan associate editor Summer weather is arriving earlier, lasting longer and packing more heat than it used to—and it's happening faster than scientists…

Why it matters

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.

Common ground

That's up from roughly four days per decade found in past research investigations up until the early 2010s.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
