‘Massive disruption’: UK’s worst-case climate crisis scenarios revealed by scientists

Scientists say government must prepare for unlikely but ‘plausible’ 4C rise in temperature and a 2-metre rise in sea levels

The worst-case impacts of the climate crisis for the UK have been laid bare by scientists, ranging from a scorching 4C rise in temperatures to a 2-metre rise in sea level. Another scenario sees a plunge of 6C in temperature after the collapse of key Atlantic Ocean currents, massively disrupting farming and energy needs.

The impacts, some of which are linked to climate tipping points, are seen as low probability but plausible. The researchers said the scenarios filled a gap in forecasting that had left the UK unprepared for extreme outcomes.
