Klimatkrisen leder till ökat antal skjutningar

Almost 8,000 shootings in US cities in recent years were attributable to unseasonably warm temperatures, according to a new study. The researchers said the work suggested the climate crisis could be contributing to increased gun violence by pushing temperatures beyond the normal ranges.

Shootings were already known to peak in summer, when people are outside more and when heat can increase aggression. But the new research took account of the season and showed that above average temperatures at any time of year increased the risk of shootings.

The study, the largest to date on the issue, assessed shooting in 100 US cities from 2015 to 2020. The scientists said the knowledge that unusually warm temperatures were linked to an increase in shooting incidents could enable community prevention measures to be targeted towards hotter days.

For most cities, the highest increased risk of shootings was between 29C (84F) and 32C.
