What happened

NOAA's National Centers for Environmental Information found that June 2026 was 1. 96 degrees Fahrenheit above the 20th-century average, making it the second-warmest June in the global record.

Why it matters

Ocean temperatures set a June record, the Arctic had its warmest June, and NOAA said 2026 is very likely to finish among the five warmest years on record, reinforcing the need to plan for heat, marine stress, and compounding weather risks.
