Climate change and recreational activities at Walden Pond have altered its ecosystem

Wed, 04/04/2018 - 13:34
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.

Algae, impurities darken Greenland ice sheet and intensify melting

Wed, 04/04/2018 - 10:47
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.

Bowhead whales, the 'jazz musicians' of the Arctic, sing many different songs

Wed, 04/04/2018 - 08:39
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.

Connection of sea level and groundwater missing link in climate response

Tue, 04/03/2018 - 11:00
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.

Great magma erup­tions had two sources

Tue, 04/03/2018 - 07:58
New research may explain controversies related to great magma eruptions.

Earth's stable temperature past suggests other planets could also sustain life

Mon, 04/02/2018 - 18:26
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 retreating across the sea floor

Mon, 04/02/2018 - 11:36
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.   

Ice-free Arctic summers could hinge on small climate warming range

Mon, 04/02/2018 - 10:07
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 visualizes the dance of a melting snowflake

Thu, 03/29/2018 - 12:31
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.

Fossils highlight Canada-Russia connection 53 million years ago

Thu, 03/29/2018 - 08:54
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.

13,000-year old human footprints found off Canada's Pacific coast

Wed, 03/28/2018 - 13:33
Human footprints found off Canada's Pacific coast may be 13,000 years old, according to a new study.

West Greenland Ice Sheet melting at the fastest rate in centuries

Wed, 03/28/2018 - 13:33
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.

Northerners have always been hardy!

Tue, 03/27/2018 - 10:17
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.

Alberta's boreal forest could be dramatically altered by 2100 due to climate change

Mon, 03/26/2018 - 10:01
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.

Arctic wintertime sea ice extent is among lowest on record

Fri, 03/23/2018 - 13:13
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.

Germany was covered by glaciers 450,000 years ago

Fri, 03/23/2018 - 09:48
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.

When the Mediteranean Sea flooded human settlements

Thu, 03/22/2018 - 10:27
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.

Landscape ridges may hold clues about ice age and climate change

Thu, 03/22/2018 - 09:32
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.

Cutting greenhouse gas emissions would help spare cities worldwide from rising seas

Wed, 03/21/2018 - 11:16
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.

Pacific influences European weather

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