A recent study has found that the climate crisis has led to a tripling in the length of ocean heatwaves, adversely affecting marine ecosystems and intensifying storm activity. Since 2000, half of these heatwaves would not have occurred without global heating, which is driven by fossil fuel combustion. Heatwaves have become not only more frequent but 1°C warmer on average, impacting vulnerable ecosystems like coral reefs and leading to stronger storms. A prime example includes the devastating flooding in Libya, exacerbated by climate-induced ocean warming. The research underscores the necessity of reducing fossil fuel use.
The climate crisis has tripled the length of ocean heatwaves, significantly harming marine ecosystems and intensifying severe weather events, with heatwaves in some areas reaching 5C hotter.
The only solution is cutting the burning of fossil fuels. This clear relationship underscores that halting atmospheric warming will also stop ocean warming.
Half of the marine heatwaves since 2000 would not have occurred without global heating, which emphasizes the urgent need for climate action.
Warmer oceans not only devastate underwater ecosystems but also supercharge storms, exemplified by the catastrophic flooding in Libya, which was made up to 50 times more likely by global heating.
