Breakthrough machine learning approach quickly produces higher-resolution climate data

Tue, 07/07/2020 - 20:42
Researchers have developed a novel machine learning approach to quickly enhance the resolution of wind velocity data by 50 times and solar irradiance data by 25 times -- an enhancement that has never been achieved before with climate data.

1.5 billion people will depend on water from mountains

Tue, 07/07/2020 - 18:33
Global water consumption has increased almost fourfold in the past 100 years, and many regions can only meet their water demand thanks to essential contributions from mountain regions. In 30 years, almost a quarter of the world's lowland population will strongly depend on runoff from the mountains. Only sustainable development can ensure the important function of mountain areas as Earth's ''water towers''.

Agriculture - a climate villain? Maybe not!

Tue, 07/07/2020 - 18:33
The UN's Intergovernmental Panel on Climate Change (IPCC) claims that agriculture is one of the main sources of greenhouse gases, and is thus by many observers considered as a climate villain.

Tree rings show unprecedented rise in extreme weather in South America

Tue, 07/07/2020 - 18:33
A new South American Drought Atlas reveals that unprecedented widespread, intense droughts and unusually wet periods have been on the rise since the mid-20th century.

Climate change may cause extreme waves in Arctic

Tue, 07/07/2020 - 18:32
Extreme ocean surface waves with a devastating impact on coastal communities and infrastructure in the Arctic may become larger due to climate change, according to a new study.

Fresh call for seagrass preservation

Tue, 07/07/2020 - 15:40
An increase in carbon dioxide emissions equivalent to 5 million cars a year has been caused by the loss of seagrass meadows around the Australian coastline since the 1950s. Researchers calculated that around 161,150 hectares of seagrass have been lost from Australian coasts since the 1950s. This has resulted in a 2 per cent increase in annual carbon dioxide emissions from land-use change.

Desert algae shed light on desiccation tolerance in green plants

Mon, 07/06/2020 - 22:27
Deserts of the US Southwest are extreme habitats for most plants, but, remarkably, microscopic green algae live there that are extraordinarily tolerant of dehydration. After completely drying out, the algae can become active and start photosynthesizing again within seconds of receiving a drop of water. Botanists provide a genetic explanation for the algae's resilience, a new perspective that warrants investigation in plants more generally.

First direct evidence of ocean mixing across the Gulf Stream

Mon, 07/06/2020 - 22:26
A new study provides first direct evidence for Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to Newfoundland and along the western coast of Europe.

Plant study challenges tropics' reputation as site of modern evolutionary innovation

Mon, 07/06/2020 - 21:08
In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as the tropics.

Heatwave trends accelerate worldwide

Mon, 07/06/2020 - 18:40
The first comprehensive worldwide assessment of heatwaves down to regional levels has revealed that in nearly every part of the world heatwaves have been increasing in frequency and duration since the 1950's. The research has also produced a new metric, cumulative heat, which reveals exactly how much heat is packed into individual heatwaves and heatwave seasons. As expected, that number is also on the rise.

Long-term consequences of river damming in the Panama Canal

Mon, 07/06/2020 - 17:18
As the demand for hydroelectricity and water increases in the tropics, a team of scientists explores the natural impacts of one of world's oldest tropical dams.

Palm trees most abundant in American rainforests

Mon, 07/06/2020 - 16:41
Characteristics of palm trees differ from those of other tropical trees in many ways. In a major new study ecologists have surveyed the actual numbers of palms in tropical rainforests around the globe. The proportion of palm trees is important to include in calculations of forests' potential carbon storage and in estimates of forested areas' sensitivity to climate change.

Earth's magnetic field can change 10 times faster than previously thought

Mon, 07/06/2020 - 16:41
A new study reveals that changes in the direction of the Earth's magnetic field may take place 10 times faster than previously thought.

MOSAiC floe: Sea ice formation

Mon, 07/06/2020 - 01:59
The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018.

Rising water temperatures could endanger the mating of many fish species

Thu, 07/02/2020 - 21:47
In a new meta-study, experts have published ground-breaking findings on the effects of climate change for fish stock around the globe.

Cause of abnormal groundwater rise after large earthquake

Thu, 07/02/2020 - 18:37
Abnormal rises in groundwater levels after large earthquakes has been observed all over the world, but the cause has remained unknown due to a lack of comparative data before and after earthquakes. After the 2016 Kumamoto earthquakes, a collaboration of scientists from Japan and the US analyzed stable isotope ratios of water samples collected before and after the disaster. This allowed them to clarify the cause of the rise in water level.

Arctic plants may not provide predicted carbon sequestration potential

Thu, 07/02/2020 - 18:37
The environmental benefits of taller, shrubbier tundra plants in the Arctic may be overstated, according to new research.

In the Arctic, spring snowmelt triggers fresh CO2 production

Thu, 07/02/2020 - 17:05
Studies have shown the Arctic is warming roughly twice as fast as the rest of the world, and its soil holds twice the amount of carbon dioxide as the atmosphere. New research finds that water from spring snowmelt infiltrates the soil and triggers fresh carbon dioxide production at higher rates than previously assumed.

Climate change threat to tropical plants

Thu, 07/02/2020 - 17:04
Half of the world's tropical plant species may struggle to germinate by 2070 because of global warming, a new study predicts.

Mystery of subterranean stoneflies unlocked

Wed, 07/01/2020 - 22:17
Researchers may have unlocked a mystery surrounding unique aquatic insects in the Flathead watershed.
