Scientists lack vital knowledge on rapid Arctic climate change

Wed, 07/18/2018 - 11:24
Arctic climate change research relies on field measurements and samples that are too scarce, and patchy at best, according to a comprehensive review study. The researchers looked at thousands of scientific studies, and found that around 30% of cited studies were clustered around only two research stations in the vast Arctic region.

Reducing carbon emissions will limit sea level rise

Mon, 07/16/2018 - 12:07
A new study demonstrates that a correlation also exists between cumulative carbon emissions and future sea level rise over time -- and the news isn't good.

Changes in Hudson River may offer insight into how glaciers grew

Fri, 07/13/2018 - 12:51
Researchers say they may be able to estimate how glaciers moved by examining how the weight of the ice sheet altered topography and led to changes in the course of the river.

5,300-year-old Iceman's last meal reveals remarkably high-fat diet

Thu, 07/12/2018 - 10:46
In 1991, German tourists discovered a human body that was later determined to be the oldest naturally preserved ice mummy, known as Otzi or the Iceman. Now, researchers who have conducted the first in-depth analysis of the Iceman's stomach contents offer a rare glimpse of our ancestor's ancient dietary habits. Among other things, their findings show that the Iceman's last meal was heavy on the fat.

How ocean warmth triggers glacial melting far away

Thu, 07/12/2018 - 10:44
The melting of glaciers on one side of the globe can trigger disintegration of glaciers on the other side of the globe, as has been presented by scientists, who investigated marine microalgae preserved in glacial deposits and subsequently used their findings to perform climate simulations.

Mapping species range shifts under recent climatic changes

Thu, 07/12/2018 - 09:05
The inclusion of taxon-specific sensitivity to a shifting climate helps us understand species distributional responses to changes in climate.

Strengthening west winds close to Antarctica previously led to massive outgassing of carbon

Tue, 07/10/2018 - 09:16
A new explanation for the Heinrich 1 event, where temperatures over Antarctica rose 5C in less than a century, suggests strengthening westerlies around the Antarctic led to a substantial increase in atmospheric carbon. Today, human-caused climate change is causing these same westerly winds to contract towards Antarctica and strengthen, suggesting an unexpected spike in carbon dioxide could occur again.

Scientists discover the world's oldest colors

Mon, 07/09/2018 - 14:27
Scientists have discovered the oldest colors in the geological record, 1.1-billion-year-old bright pink pigments extracted from rocks deep beneath the Sahara desert in Africa.

Fingerprint of ancient abrupt climate change found in Arctic

Mon, 07/09/2018 - 10:11
A research team found the fingerprint of a massive flood of fresh water in the western Arctic, thought to be the cause of an ancient cold snap that began around 13,000 years ago.

Scientists capture breaking of glacier in Greenland

Mon, 07/09/2018 - 09:11
A team of scientists has captured on video a four-mile iceberg breaking away from a glacier in eastern Greenland, an event that points to one of the forces behind global sea-level rise.

First dogs in the Americas arrived from Siberia, disappeared after European contact

Thu, 07/05/2018 - 13:35
A new study offers an enhanced view of the origins and ultimate fate of the first dogs in the Americas. The dogs were not domesticated North American wolves, as some have speculated, but likely followed their human counterparts over a land bridge that once connected North Asia and the Americas, the study found.

What does global climate have to do with erosion rates?

Thu, 07/05/2018 - 10:40
Geoscientists have been intrigued by a potential link between erosion rates at the Earth's surface and changes in global climate. A new study now calls into question this link. A team of researchers re-examined 30 locations with reported accelerated erosion after the onset of glacial-interglacial cycles a few million years ago. In nearly all of the locations, the proposed link between erosion and global climate could not be confirmed.

Tiny fine particles of global impact -- radiocarbon reveals the origin of black carbon

Thu, 07/05/2018 - 10:00
A technical breakthrough was achieved in the source determination of very small carbon samples at the Accelerator Laboratory and the Laboratory of Chronology of the University of Helsinki. The development work is essential in climate research as it facilitates disentangling the origin of, for instance, black carbon particles.

Global warming may be twice what climate models predict

Thu, 07/05/2018 - 10:00
Future global warming may eventually be twice as warm as projected by climate models under business-as-usual scenarios and even if the world meets the 2°C target sea levels may rise six meters or more, according to an international team of researchers from 17 countries.

Oxygen loss in the coastal Baltic Sea is 'unprecedentedly severe'

Thu, 07/05/2018 - 07:42
The Baltic Sea is home to some of the world's largest dead zones, areas of oxygen-starved waters where most marine animals can't survive. But while parts of this sea have long suffered from low oxygen levels, a new study shows that oxygen loss in coastal areas over the past century is unprecedented in the last 1,500 years.

New study questions when the brown bear became extinct in Britain

Wed, 07/04/2018 - 10:20
New research provides insights into the extinction of Britain's largest native carnivore. The study is the first of its kind to collate and evaluate the evidence for the brown bear in post-Ice Age Britain.

Rising sea levels could cost the world $14 trillion a year by 2100

Tue, 07/03/2018 - 18:07
Failure to meet the United Nations' 2ºC warming limits will lead to sea level rise and dire global economic consequences, new research has warned. A study found flooding from rising sea levels could cost $14 trillion worldwide annually by 2100, if the target of holding global temperatures below 2ºC above pre-industrial levels is missed.

Marine mammals most at risk from increased Arctic ship traffic

Mon, 07/02/2018 - 12:38
The first comprehensive survey of Arctic marine mammal populations' vulnerability to shipping along two main routes finds which face the most risks from heavier traffic in the region.

Greenhouse gases were the main driver of climate change in the deep past

Mon, 07/02/2018 - 10:12
Greenhouse gases were the main driver of climate throughout the warmest period of the past 66 million years, providing insight into the drivers behind long-term climate change.

Climate change is making night-shining clouds more visible

Mon, 07/02/2018 - 10:11
Increased water vapor in Earth's atmosphere due to human activities is making shimmering high-altitude clouds more visible, a new study finds. The results suggest these strange but increasingly common clouds seen only on summer nights are an indicator of human-caused climate change, according to new research.
