It would primarily be driven by climate change caused by human activities, researchers in Australia said. The team looked at evidence of historic global warming in fossilized corals and ancient sediments from the red sea. About 125,000 years ago, global temperatures were a degree warmer than now.
Antarctica melted at a rapid rate, and sea levels rose as much as 11.2 feet every 100 years for several centuries. That terrifying rise could be mirrored over the next few hundred years, scientists warned. That’s because today, man-made climate change is fast the melting of Antarctica’s ice sheets.
“We do not predict the future, but we show what nature will do even without human interference in the climate,” said professor Eelco Rohling, of the Australian National University.
Nature knows how to go much quicker than we thought.”
Previous research has warned that rising sea levels threaten to flood the homes of 480million people by 2100. The rise could lead to a total loss of land of 700,000 square miles, an area seven times the size of the UK. A recent Pentagon report warned that the United States’ electrical grids and other infrastructure may collapse as Earth heats up.
The new paper suggests Antarctica’s melting ice sheets are an even bigger contributor to global sea level rises than we thought.
“The rate of warming is much faster now – the warming is more extreme – and it’s happening at both poles at the same time,” scientist Dr. Fiona Hibbert said. If both the Greenland and Antarctic ice shelves melt, sea levels will rise about 200 feet.
“As soon as it’s more than four meters [13ft], all of the big coastal cities are going to have to be moved,” professor Rohling said. If follows a declaration from 11,000 scientists on Tuesday that Earth had entered a global “climate emergency”.
Researchers from 153 countries warned that we have a tendency to face “untold human suffering” if more is not done to slow down climate change.
They put forward many routes through which humanity can save itself. These included a shift away from meat-heavy diets, greater stress on green energy, and having fewer kids.
