Glaciers in Alaska's Denali National Park are melting faster than at any time in the past four centuries because of rising summer temperatures, a new study finds.

A research team has identified the formation of natural gas hydrates, so-called flammable ice, formed in oceans.

An interdisciplinary team of scientists examining everything from glaciology to freshwater ecology discovered drastic changes over the past decade to the world's largest High Arctic lake. And from glacial melt to the declining lake ice to changes in lake ecology, the results from Lake Hazen on Ellesmere Island in Canada are alarming.

At 3.5 meters long and with a shoulder height of 1.7 meters, the cave bear was one of the giants of the Ice Age. Yet few appear to have survived until the last glacial maximum 24,000 to 19,000 years ago. Researchers have conducted analyses to find out what likely caused the extinction of these large herbivores. It is believed that the renewed cooling of the climate and hunting by humans -- added to the bears purely vegetarian diet -- increased the pressure on this megafauna species.

Climate change and recreational activity at Walden Pond may have altered the ecology of this iconic lake during the past 1,800 years, affecting the water quality and plankton community, according to a new study.

The Dark Zone of the Greenland ice sheet has major impact on the surface melt of this immense store of ice. A new study -- based on drone surveys -- suggests that ice algae, dust and soot from wildfires and combustion are the main cause.

Four winters of audio recordings of bowhead whales singing under the ice off Greenland show a surprise variety in this animal's repertoire. Bowhead whales' vocalization patterns are very different from the only other whale known to make distinct songs, the humpback.

About 250 million years ago, when the Earth had no ice caps and the water around the equator was too hot for reptiles, sea level still rose and fell over time. Now, an international team of researchers has developed a way to track sea-level rise and fall and to tease out what caused the changes in the absence of ice sheets.

New research may explain controversies related to great magma eruptions.

Research about temperatures on the early Earth have ranged from a virtually ice-covered surface to a very hot planet that could not support most of today's lifeforms. New computer simulations show fairly moderate average temperatures and more stable ocean pH -- which helps explain how life evolved here, and might emerge on other planets.

Antarctica’s great ice sheet is losing ground as it is eroded by warm ocean water circulating beneath its floating edge, a new study has found.   

A range of less than one degree Fahrenheit (or half a degree Celsius) of climate warming over the next century could make all the difference when it comes to the probability of future ice-free summers in the Arctic, new research shows.

NASA has produced the first three-dimensional numerical model of melting snowflakes in the atmosphere. The model provides a better understanding of how snow melts can help scientists recognize the signature in radar signals of heavier, wetter snow -- the kind that breaks power lines and tree limbs -- and could be a step toward improving predictions of this hazard.

A new 53 million-year-old insect fossil called a scorpionfly discovered at B.C.'s McAbee fossil bed site bears a striking resemblance to fossils of the same age from Pacific-coastal Russia, giving further evidence of an ancient Canada-Russia connection.

Human footprints found off Canada's Pacific coast may be 13,000 years old, according to a new study.

New study from the West Greenland Ice Sheet shows that weather patterns and summer warming combine to drive ice loss that is at the highest levels in at least 450 years.

Pioneering early people who lived at the end of the last ice age actually carried on with life as usual despite plummeting temperatures, a study at a world-famous archaeological site in North Yorkshire suggests.

Half of Alberta's upland boreal forest is likely to disappear over the next century due to climate change, a new study shows. The upland forest will be replaced after wildfire by open woodland or grassland, according to research from biologists.

Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists.

Researchers have obtained new chronological data for the timing of the Elsterian and Saalian glacial cycles in central Germany. They found that the first Quaternary glaciation, which covered huge parts of Europe in ice, occurred as early as 450,000 years ago and not - as previously thought - around 350,000 years ago. The researcher further showed that once these glaciers had retreated, the first people appeared in central Germany around 400,000 years ago.
