A group of UK scientists found that a “staggering” 28 trillion tonnes of ice has disappeared from the surface of the Earth since 1994. By analyzing satellite surveys, the group found that melting glaciers and ice sheets could cause sea levels to rise dramatically.

A “staggering” 28 trillion tonnes of ice has disappeared from the surface of the Earth since 1994, a group of UK scientists has found.

Scientists from Leeds and Edinburgh universities and University College London analyzed satellite surveys of glaciers, mountains, and ice sheets between 1994 and 2017 to _____(3 words missing) of global warming. Describing the ice loss as “staggering,” the group found that melting glaciers and ice sheets could cause sea levels to rise dramatically, possibly reaching a meter (3 feet) by the end of the century.

“To put that in context, every centimeter of sea-level rise means about a million people will be displaced from their low-lying homelands,” Professor Andy Shepherd said. The dramatic loss of ice could have other severe consequences, including major _____(1 word missing) to the biological health of Arctic and Antarctic waters and reducing the planet’s ability to reflect solar radiation back into space.

“In the past researchers have studied individual areas – such as the Antarctic or Greenland – where ice is melting. But this is the first time anyone has looked at all the ice that is disappearing from the entire planet,” said Shepherd, “What we have found has stunned us.” “There can be little doubt that the vast majority of Earth’s ice loss is a direct consequence of climate warming,” the group wrote.

The Greenland ice sheet is the world’s second-largest ice body. According to the researchers, snowfall that replenishes the country’s glaciers each year can no longer _____(3 words missing) the pace of ice melt, which means that the Greenland ice sheet will continue to lose ice even if global temperatures stop rising.
