Global warming has already wreaked havoc on the world’s glaciers. In a new paper published in the journal Science, researchers found that nearly 40 percent of the world’s glaciers are irreversibly doomed, even if global temperatures stopped rising.

Those involved with the study determined that glaciers will soon lose 39 percent of their mass relative to 2020. That outcome, which is the best case scenario, will also push up sea levels.

If the world continues its current climate policies things will get even worse. In fact, in that case, the number will rise to 76 percent, meaning the world would be unable to stymie global warming.

That outcome would spell trouble for countries that use glacial water for everything from growing food to power, as well as those that thrive on glacier touris
