A new study reveals that summer is arriving earlier and lasting longer due to climate change, with significant consequences for daily life and infrastructure. The research found that summer length has increased by around six days per decade between 1990 and 2023.
Climate change is causing summer to arrive earlier and last longer. Research from the University of British Columbia found that between 1990 and 2023, summer length increased by around six days per decade. Compared to the 1960s, summer is now about 30 days longer. Cities like Sydney, Toronto, and Minneapolis have seen significant increases in summer length. The change is driven by rising greenhouse gas emissions and has serious ecological consequences, including disruptions to seasonal systems and increased risk of flash floods. Many cities are unprepared for the earlier arrival of heat, and measures such as cooling centers and public heat warnings are often not ready in time.
