Glaciers

This week, some of the world's most exciting and remote destinations are available at up to 50 percent off with Hurtigruten Expeditions, the world's leading expedition cruise company.

Two ice quakes strong enough to be measured on seismometers have hit the same region of Alaska this week as the Northwest experiences a record heat wave.

Over the past decade, landslides have been responsible for generating giant waves in Alaska and Greenland.

The ocean floor is sinking under the weight of climate change and calculations to determine sea level rise don't take that fact into equation. Researchers propose a new, more accurate method instead.

The 27 January marks the first time the Antarctica mainland was seen with human eyes. Two hundred years later and it approaches a tipping point of irreversible glacial melt.

Researchers find first direct evidence of a "glacial oxygen pump," which they say extended an essential lifeline to the simple life forms that inhabited the Earth at the time.

Floating ice shelves that encircle mainland Antarctica have been thinning in recent years, but the effect this has had on ice loss from the continent's interior has remained unclear.

One of the islands is about the size of 10 football fields.

Professor David Holland of NYU told Newsweek that the melting "could have a major impact on global sea-level rise over this century and beyond if this loss of East Antarctic ice continues at the present rate."

These rock formations help to support the idea of a rapid Earth freeze over 700 million years ago.

There are about 400 subglacial lakes around the world, but these are the first scientists believe to be salty.

Between 2010 and 2016, an area of Antarctica's submerged ice roughly the size of London melted.

The glaciers have been shrinking since the 1960s.

A new technique compiled hundreds of thousands of images over seven years.

Satellite data over 25 years confirms what climate models had predicted.

"This is sort of a dark archaeology, where we benefit from climate change that's making this ice melt."

This heat source is found all over the planet and is extremely difficult to measure.

The fates of lava and ice are forever entwined.

Melting of the Aurora Basin in East Antarctica could cause 10 to 15 feet of sea level rise on its own.

The worst scenario would flood lands that are home to 236 million people.

The 700-foot tall, 300-mile-long wall has been protecting the Seven Kingdoms for thousands of years. Would it hold up on Earth?

The glacier has long been receding.

Less extensive glaciers could mean more volcanic activity.

What scientists are monitoring, what happened last time it erupted and, of course, how to pronounce that mouthful.

A new measuring technique is giving us a grim look at just how fast America's glaciers are melting.

Fierce volcanic activity near the Vatnajökull glacier between 2014 and 2015 created huge calderas.

The unusual crack in the center of the ice shelf could break off and form a giant iceberg.

Imja Tsho has been rapidly expanding due to climate change.

The effect hasn't been included in global climate models.

Rising temperatures have caused an environmental disaster, according to the IOM.
