Soaring temperatures shattered records from Ottawa to Oman this week, as the Northern Hemisphere endured an oppressive hot spell. A heat dome cooked much of the eastern United States and parts of Canada, setting all-time temperature records in New Hampshire, Vermont and Montreal, where extreme heat took the lives of dozens of people in the city and the surrounding areas.

The scorcher is an urgent reminder that climate change is already fueling dangerous heat, and that rising temperatures will imperil a growing a number of people in the years to come.
Carbon pollution from cars, trucks, factories, farms and power plants is trapping heat, driving up the average surface temperature of the Earth. This is shifting the entire distribution of temperatures, meaning we see fewer cold days and more warm days. When the weather is so hot it breaks records, look for a human fingerprint.
