Summer Could Be One Long Heatwave If Planet Hits 2 Degrees Celsius

How heatwaves will change around the world for every 1°C increase in global average temperatures.

Summer in some regions of the world will become one long heatwave even if global average temperatures rise only 2°C above pre-industrial levels and certain regions may become close to unliveable if temperatures increase by 5°C.

Even with just a 1.5°C increase in global temperatures there are significant changes to the length, intensity, and frequency of heat waves in every part of the world.

That's the finding of new research by Dr Sarah Perkins-Kirkpatrick from the ARC Center of Excellence for Climate system Science published Thursday in Scientific Reports that divides the globe into 26 regions and looks at how heatwaves will change with every 1°C rise in global temperatures.
