According to the latest data from NOAA's 2025 Global Climate Analysis, last year was the third-warmest year ever recorded on Earth, with several regions experiencing their second-warmest years on record. The impacts were widespread, with the Arctic seeing record-low sea ice, the UK hit by its strongest storm in a decade, Asia facing heat waves and crop failures, and North America dealing with catastrophic flooding and hurricanes.

Why it matters

These extreme weather events are not isolated incidents, but rather part of a larger pattern driven by global warming. Scientists agree that while weather has always been unpredictable, the intensity and frequency of these events are amplified by climate change, posing serious threats to communities worldwide.

The details

In the United States, 2025 ranked as the fourth-warmest year on record, with October setting a new record as the hottest October ever. The Arctic Region experienced its second-warmest year, with sea ice extent reaching record lows. Asia saw its third-warmest year, with Japan setting new heat records and Thailand facing catastrophic flooding. Africa ranked as the seventh-warmest year on record, while Brazil experienced severe flooding and landslides. North America's fourth-warmest year included devastating flash floods in Texas and back-to-back hurricanes in Mexico.

  • In 2025, the Arctic Sea Ice Extent reached its tenth-smallest minimum and lowest maximum ever recorded.
  • In July and August 2025, Japan set new heat records, leading to hospitalizations and crop failures.
  • In November 2025, Thailand faced catastrophic flooding after record-breaking rainfall.
  • In June and September 2025, Mexico was hit by Hurricane Erick and Tropical Storm Barry, respectively.
