Deadly heatwaves to persist for 1,000 years post-net zero

Deadly heatwaves to last 1,000 years, even post-net zero.

Why it matters

  • Long-term climate impacts persist even after net zero emissions.

By the numbers

  • 1,000 years: heatwave duration post-net zero.
  • Delay worsens severity.

The big picture

  • Southern Ocean warming drives heatwave persistence.

What they're saying

  • No carbon capture assumed; solutions could mitigate impacts.
  • Mixed public reactions: pessimism and calls for action.

Caveats

  • Assumes no carbon capture.
  • Uncertainties in long-term projections.

What’s next

  • Carbon capture, faster net zero may help.
