Planet-warming greenhouse gas emissions are expected to jump to 75 billion tonnes a year by 2050 – a nearly 50 per cent increase from today. 

This will continue to destabilize the climate and lead to a surge in heatwaves, which are expected to affect nearly everyone on Earth – some 9.2 billion people – by 2050. 

Almost no corner of the planet will remain untouched by extreme heat.
