On Aug. 18, 2019, Iceland held a funeral for the first glacier lost to climate change. The deceased party was Okjökull, a historic body of ice that covered 14.6 square miles (38 square kilometers) in the Icelandic Highlands at the turn of the 20th century. But, in 2014, having dwindled to less than 1/15 its former size, Okjökull lost its status as an official glacier. As a plaque was installed at the ceremony, Iceland's Prime Minister, Katrín Jakobsdóttir, warned that if current trends continue, her country stands to lose even more arctic sea ice in the near future.
The overwhelming evidence is clear: Greenhouse gas emissions (and other human activities) are radically transforming the planet on which we live. As a result, California's wildfire season is getting longer; thawing permafrost has destabilized Russian infrastructure; and yes, most of the world's glaciers are swiftly retreating.
