Global warming is in the dock again. Glaciers in North America have been melting at an alarming rate since 1958, according to the US Geological Survey. And it’s due to global warming.

The USGS studied three glaciers: the Wolverine and Gulkana glaciers in Alaska and the South Cascade Glacier in washington State.

They were used as ‘benchmarks’ as their differing elevations and climates are representative of glaciers across North America.

Wolverine and Gulkana have both lost about fifteen per cent of their mass in the last fifty years. Even more worrying, the South Cascade has lost nearly 25% of its mass.

USGS scientist Edward Josberger commented, “climate change effects are starting to become more and more noticeable”
