The US Geological Survey has unveiled an alarming fact that global warming has melted glaciers in North America at an accelerating rate since 1958.
Melting of glaciers at an accelerating rate would definitely result into drought risks and rising sea levels.
The U.S. geological survey study focused on three glaciers viz. the South Cascade Glacier in Washington and the Wolverine and Gulkana in Alaska. These three glaciers are also known as "benchmark glaciers" as their varying climates and elevations represent thousands of other glaciers across the continent.
The survey shows that both, the Wolverine and Gulkana glaciers have lost approximately 15 percent of their mass since 1958. While, the South Cascade Glacier has lost almost a quarter of its mass.
Edward Josberger, a scientist with the USGS said, "Climate change effects are starting to become more and more noticeable."
Scientists say that thinning glaciers are clearly the outcome of global warming.
