A study published Wednesday shows nearly all the world’s glaciers have been melting at an accelerated pace in recent years, accounting for rises in sea level over the last two decades. In the study, published in the science journal Nature, an international group of scientists used high resolution imagery from NASA’s Terra satellite to study 220,000 […]
“Faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s.” Since 1980, the planet’s north and south poles have moved roughly four meters in distance, and new research shows that shifts in the Earth’s rotational axis have accelerated since the 1990s as a […]
In 1958, a magnitude 7.8 earthquake triggered a rockslide into Southeast Alaska’s Lituya Bay, creating a tsunami that ran 1,700 feet up a mountainside before racing out to sea. Researchers now think the region’s widespread loss of glacier ice helped set the stage for the quake. In a recently published research article, scientists with the University […]
The loss of glaciers worldwide enhances the breakdown of complex carbon molecules in rivers, potentially contributing further to climate change. University of Alaska Southeast Professor of Environmental Science Eran Hood was part of an international research team led by the University of Leeds that has for the first time linked glacier-fed mountain rivers with higher […]
