Glaciers in the Juneau Icefield in southeastern Alaska are melting at a faster rate than previously thought and may reach an irreversible tipping point sooner than expected, according to a study ...
A National Park Service report on Alaska's glaciers noted glaciers within Alaska national parks shrank 8% between the 1950s and early 2000s and glacier-covered area across the state decreased by ...
Alaska's mighty Muldrow Glacier is moving 50 to 100 times faster than normal. It's a major surge. Large parts of the 39-mile-long "river of ice" are progressing some 30 to 60 feet per day, as ...
Examples of tipping points include thawing permafrost, which will release methane, a powerful greenhouse gas, or melting ice sheets and glaciers reducing Earth's albedo, which would warm the planet faster. Thawing permafrost is a threat multiplier because it holds roughly twice as much carbon as the amount currently circulating in the atmosphere.
Sea levels are rising because polar ice caps are melting at a rapid pace. This process starts in the Arctic region, specifically in Alaska. Researchers at Oxford University explained that increasing temperatures, melting glaciers, thawing permafrost, and rising sea levels are all indications of warming throughout the Arctic. [35]
The rapid retreat of the Cordilleran ice sheet is a focus of study by glaciologists seeking to understand the difference in patterns of melting in marine-terminating glaciers, glaciers whose margin extends into open water without seafloor contact, and land-terminating glaciers, with a land or seafloor margin, as scientists believe the western ...
Photojournalist Larry Pannell estimates around "two thirds" of the Sawyer Glacier has disappeared since he first visited in 2012. Climate change: Shocking photos show Alaska glacier melting Skip ...
A new scientific study published Thursday suggests the world should start preparing to protect the ecosystems that emerge from under the disappearing ice, as a warming planet is inevitably causing ...
