The research, published in the journal Nature, used climate models to see how factors such as air and ocean temperatures have influenced hurricanes. Projections into the future were then made, based upon various levels of planetary warming.
The findings suggest that enormously destructive storms have already been bolstered by climate change and similar events in the future are on course to be cataclysmic.
In a world where temperatures were 3C warmer on average, Hurricane Katrina, which resulted in nearly 2,000 deaths when levees breached near New Orleans in 2005, would’ve been even worse, with around 25% more rainfall. Cyclone Yasi, which hit Australia in 2011, would have had around a third more rain, while the deluge during Gafilo, a huge storm that killed more than 300 people in Madagascar in 2004, would have been 40% more intense.
