Climate change: How bad can it get?


Heatwaves Some 1.5 billion people will be exposed to heatwaves every year by 2100 under 2C, according to Avoid 2, a British government-funded consortium of climate change research institutes. Even a 2C rise as targeted by the UN would submerge land currently occupied by 280 million people, according to Climate Central, a US-based research group. The change could take a few hundred years, or up to 2,000 years. Treasures of nature, civilisation From the glimmering coral of the Great Barrier Reef to Mount Fuji and the canal-crossed city of Venice, global warming may spell the ruin of some of the most precious jewels of nature and civilisation, UNESCO warns. Climate change threatens a range of other treasures as well, says UNESCO.
