Century of data shows sea-level rise shifting tides in Delaware, Chesapeake bays

Wed, 01/24/2018 - 16:24
The warming climate is expected to affect coastal regions worldwide as glaciers and ice sheets melt, raising sea level globally. For the first time, an international team has found evidence of how sea-level rise already is affecting high and low tides in both the Chesapeake and Delaware bays, two large estuaries of the eastern United States.

Earth's core and mantle separated in a disorderly fashion

Wed, 01/24/2018 - 12:17
Plumes of hot rock surging upward from the Earth's mantle at volcanic hotspots contain evidence that the Earth's formative years may have been even more chaotic than previously thought, according to new work.

Record jump in 2014-2016 global temperatures largest since 1900

Wed, 01/24/2018 - 11:32
Global surface temperatures surged by a record amount from 2014 to 2016, boosting the total amount of warming since the start of the last century by more than 25 percent in just three years, according to a new University of Arizona-led paper. The research is the first to quantify the record temperature spike of an additional 0.43 degrees F (0.24 C) in just three years and to identify the fundamental reason for the jump.

Interacting Antarctic glaciers may cause faster melt and sea level contributions

Wed, 01/24/2018 - 07:55
Two of the most rapidly changing glaciers in Antarctica, which are leading contributors to sea-level rise, may behave as an interacting system rather than separate entities, according to a new analysis of radar data.

Warming temperatures may cause birds to shrink

Wed, 01/24/2018 - 07:55
Biologists have known for a long time that animals living in colder climates tend to have larger bodies, supposedly as an adaptation to reduce heat loss. However, a new study shows that this trend in birds might actually be due to the effects of high temperatures during development -- raising new alarms about how populations might be affected by global warming.

Frozen in time: Glacial archaeology on the roof of Norway

Tue, 01/23/2018 - 22:51
Artefacts revealed by melting ice patches in the high mountains of Oppland shed new light on ancient high-altitude hunting.

Solar power is suited for the energy use of sports halls

Tue, 01/23/2018 - 09:22
Researchers studied the energy consumption of indoor swimming pools and practice indoor ice rinks, and use of solar power in them. It is possible to cover 30% per cent of the energy need of such sites with solar power. However, the storage of solar energy poses a big challenge for increasing the use of solar power.

Discrepancies between satellite and global model estimates of land water storage

Mon, 01/22/2018 - 15:47
Researchers have found that calculations of water storage in many river basins from commonly used global computer models differ markedly from independent storage estimates from GRACE satellites.

Heat loss from Earth's interior triggers ice sheet slide towards the sea

Mon, 01/22/2018 - 08:13
In North-East Greenland, researchers have measured the loss of heat that comes up from the interior of the Earth. This enormous area is a geothermal 'hot spot' that melts the ice sheet from below and triggers the sliding of glaciers towards the sea.

Long-term warming trend continued in 2017: NASA, NOAA

Thu, 01/18/2018 - 16:37
Continuing the planet's long-term warming trend, globally averaged temperatures in 2017 were 1.62 degrees Fahrenheit (0.90 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists.

New landform discovered from the depths of Finnish forest

Thu, 01/18/2018 - 09:13
Scientists have been familiar with Finnish landforms for decades. Now, however, researchers have discovered a new landform previously unknown to science with the aid of laser technology. After the initial discovery in Finland, similar forms have also been found in Sweden.

Warming Arctic climate constrains life in cold-adapted mammals

Thu, 01/18/2018 - 09:08
A new study has uncovered previously unknown effects of rain-on-snow events, winter precipitation and ice tidal surges on the muskoxen.

Release of ancient methane due to changing climate kept in check by ocean waters

Wed, 01/17/2018 - 15:40
Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere.

New light on the mysterious origin of Bornean elephants

Wed, 01/17/2018 - 07:55
How did Borneo get its elephant? This could be just another of Rudyard Kipling's just so stories. The Bornean elephant is a subspecies of Asian Elephants that only exist in a small region of Borneo. Their presence on this southeastern Asian island has been a mystery. Scientists have discovered that elephants might have arrived on Borneo at a time of the last land bridge between the Sunda Islands in Southeast Asia.

Weather anomalies accelerate the melting of sea ice

Tue, 01/16/2018 - 21:25
Researchers reveal why Arctic sea ice began to melt in the middle of winter two years ago -- and that the increased melting of ice in summer is linked to recurring periods of fair weather.

Scientists home in on a potential Anthropocene 'Golden Spike'

Tue, 01/16/2018 - 12:13
Scientists are reviewing the potential settings where a global reference section for the Anthropocene might be searched.

Scientists home in on a potential Anthropocene 'Golden Spike'

Mon, 01/15/2018 - 08:51
A new study suggests that key geological markers align towards a start for the Anthropocene somewhere between 1952 to 1955, based on signals from nuclear testing and fossil fuel burning.

Machine learning predicts new details of geothermal heat flux beneath the Greenland Ice Sheet

Thu, 01/11/2018 - 10:53
A new article uses machine learning for the first time to craft an improved model for understanding geothermal heat flux -- heat emanating from the Earth's interior -- below the Greenland Ice Sheet.

Combined effects of climate change and forest fires

Wed, 01/10/2018 - 09:10
A new study has tracked the ebb and flow of ecosystem changes over the last 10,000 years, showing patterns that could shed light on current climate change and its role in shaping the world's forests.

US rivers and streams are compromised by increasing salt loads

Mon, 01/08/2018 - 15:12
Human activities are exposing US rivers and streams to a cocktail of salts, with consequences for infrastructure and drinking water supplies. So reports a new study that is the first to assess the combined, long-term changes in freshwater salinity and alkalization across the country.
