Key Points:
- Researchers have determined that the intense heatwave affecting much of the US this week would have been "virtually impossible" without the influence of the climate crisis, which has raised global temperatures by 1.4°C (2.5°F).
- The heat dome causing hot and humid conditions across central and eastern US and southern Canada is a rare event, estimated to occur once every 200 years, but would have been even rarer without human-driven climate change.
- The extreme heat threatens major events, including the 250th Independence Day celebrations in Washington DC and World Cup matches in Philadelphia and Miami, where conditions may be unsafe for players and fans.
- Climate scientists emphasize the urgent need to reduce greenhouse gas emissions immediately to prevent worsening impacts, highlighting that climate change is already disrupting everyday life and major cultural events.
- Experts warn that continued delays in transitioning to net zero emissions will exacerbate heatwaves and other climate-related hazards, underscoring the importance of swift climate action.
