Are the melting glaciers of Yosemite Park a sign of global warming or global hype?

Half Dome

Half Dome

John Muir noted 150 years ago that Yosemite’s Lyell Glacier was a river of ice that stretched for 1,000 yards, but since that time has shrunk to 66 acres. Called a living glacier by Muir, global warming alarmists point to it as proof of #Climate Change. So did President #Obama this summer. There’s only one problem: the glacier has been steadily melting since we left the Little Ice Age in 1850.

Those who visit the Lyell Glacier can hear the steady whoosh of water flowing under its massive base, exposing bedrock up its spine. Obama pointed to Lyell Glacier as evidence of climate change when he visited Yosemite National Park in early June. Obama said the glacier had once been a mile wide, “but now it’s almost gone.” His visit came shortly after the United Nations released a report on famous landmarks that global warming may destroy. It was a perfectly orchestrated plan to justify more regulations before leaving office.

Global warming not the culprit

Yet Yosemite geologist Greg Stock and naturalist Pete Devine said their research does not show that global warming is behind the melting glaciers, despite increased greenhouse gases. Devine and Stock say the glaciers that still remain in the park—a remnant from the last glaciation over 15,000 years ago—are responsible for the park’s iconic landscapes. Over time, the glaciers have created such formations as El Capitan, the Half Dome, and the Yosemite Valley that brings in visitors from around the world.
