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.

Around 7,600 years ago, the emergence of agricultural settlements in Southeastern Europe and subsequent progress of civilization suddenly came to a standstill. This was most likely caused by an abrupt sea level rise in the northern Aegean Sea. Researchers have now detected evidence of this in the fossils of tiny calcifying marine algae preserved in seafloor sediments.

Researchers say the landscape may also hold answers to how glaciers helped form the current terrain and provide insight into the progression of climate change.

Coastal cities worldwide would face a reduced threat from sea level rise if society reduced greenhouse gas emissions, with especially significant benefits for New York and other US East Coast cities, new research indicates.

Sea surface temperature in the distant tropical Pacific can influence November weather in Europe.

A long debate of the role of the sea ice and the winter temperatures in Eurasia has got a new contribution. Probably no connection, a new study says.

A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, says a researcher.

Targeted geoengineering to preserve continental ice sheets deserves serious research and investment, argues an international team of researchers. Without intervention, by 2100 most large coastal cities will face sea levels that are more than three feet higher than they are currently.
