This is the conclusion from the first study to compare and contrast the consequences of 1.5C world compared to a 2C world, published today in Earth System Dynamics.

Both 2C and 1.5C are explicitly mentioned in the Paris agreement as potential upper limits for global warming since the preindustrial era, but details from scientists on how the temperature thresholds compare have been sparse.

For example, an extra 0.5C could see global sea levels rise 10cm more by 2100, water shortages in the Mediterranean double and tropical heatwaves last up to a month longer. The difference between 2C and 1.5C is also “likely to be decisive for the future of coral reefs”, with virtually all coral reefs at high risk of bleaching with 2C warming.

@Jack Son,

Thank you for your comment. Can you please provide the link to that publication?
