New version of Earth model captures climate dynamics

Tue, 03/03/2020 - 18:33
A new high-resolution Earth systems model has been designed to predict climate trends into the next century. The model will provide the scientific basis by which to mitigate the effects of extreme climate on energy and other essential services.

World's sandy beaches under threat from climate change

Tue, 03/03/2020 - 18:32
Half of the world's beaches could disappear by the end of the century due to coastal erosion, according to a new study led by the Joint Research Centre, the European Commission's science and knowledge service.

Putting a price on the protective power of wetlands

Mon, 03/02/2020 - 22:36
In coastal communities prone to hurricanes and tropical storms, people typically turn to engineered solutions for protection: levees, sea walls and the like. But a natural buffer in the form of wetlands may be the more cost-effective solution.

Geologists determine early Earth was a 'water world' by studying exposed ocean crust

Mon, 03/02/2020 - 19:24
Geologists have studied exposed, 3.2-billion-year-old ocean crust in Australia and used that rock data to build a quantitative, inverse model of ancient seawater. The model indicates the early Earth could have been a 'water world' with submerged continents.

Directed species loss from species-rich forests strongly decreases productivity

Mon, 03/02/2020 - 18:33
At high species richness, directed loss, but not random loss, of tree species strongly decreases forest productivity. This is shown by data from a big forest project in China. Previous studies based on random species loss could therefore bias the predictions of how more realistic extinction scenarios are likely to affect ecosystem functioning.

Ocean changes almost starved life of oxygen

Mon, 03/02/2020 - 18:33
Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.

Federally protected lands reduce habitat loss and protect endangered species

Mon, 03/02/2020 - 17:37
Using more than 30 years of earth satellite images, scientists at have discovered that habitat loss for imperiled species in the US over this period was more than twice as great on non-protected private lands than on federally protected lands. The study provides evidence that federal land protection and listing under the US Endangered Species Act are effective tools for stemming losses in species habitat.

Containing methane and its contribution to global warming

Fri, 02/28/2020 - 19:52
Methane is a gas that deserves more attention in the climate debate as it contributes to almost half of human-made global warming in the short-term. A new study shows that it is possible to significantly contribute to reduced global warming through the implementation of available technology that limits methane release to the atmosphere.

How much does black carbon contribute to climate warming?

Fri, 02/28/2020 - 17:52
Black carbon particles -- more commonly known as soot -- absorb heat in the atmosphere. For years, scientists have known that these particles are having an effect on Earth's warming climate, but measuring their exact effect has proved elusive.

Study shows rapid sea level rise along Atlantic coast of North America in 18th century

Fri, 02/28/2020 - 17:22
Sea levels along a stretch of the Atlantic coast of North America in the 18th century were rising almost as fast as in the 20th century, a new study has revealed.

A dam right across the North Sea

Fri, 02/28/2020 - 17:22
A 475-km-long dam between the north of Scotland and the west of Norway and another one of 160 km between the west point of France and the southwest of England could protect more than 25 million Europeans against the consequences of an expected sea level rise of several meters over the next few centuries.

Deep-sea coral gardens discovered in the submarine canyons off south Western Australia

Fri, 02/28/2020 - 17:22
Stunning 'gardens' of deep-sea corals have been discovered in the Bremer Canyon Marine Park by Australian and international scientists during an oceanographic expedition.

Big data helps farmers adapt to climate variability

Thu, 02/27/2020 - 21:42
A new study has precisely quantified soil and landscape features and spatial and temporal yield variations in response to climate variability.

New method converts carbon dioxide to methane at low temperatures

Thu, 02/27/2020 - 18:45
Scientists developed a new method to convert carbon dioxide to methane with an electric field at low temperatures. In comparison to previous methods, this new method can produce any amount of methane whenever necessary. Because methane is a valuable gas which can be used to generate heat and electricity, this method could be exploited to help reduce the use of fossil fuels and prevent global warming.

Antarctic ice walls protect the climate

Thu, 02/27/2020 - 18:45
Inland Antarctic ice contains volumes of water that can raise global sea levels by several meters. A new study shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.

Freshwater flowing into the North Pacific plays key role in North America's climate

Wed, 02/26/2020 - 21:54
Massive freshwater river flows stemming from glacier-fed flooding at the end of the last ice age surged across eastern Washington to the Columbia River and out to the North Pacific Ocean, where they triggered climate changes throughout the northern hemisphere.

Complex local conditions keep fields of dunes from going active all at once

Wed, 02/26/2020 - 21:21
New research on sand dunes in China describes how even neighboring dunes can long remain in different and seemingly conflicting states -- confounding the assessment of stabilization efforts and masking the effects of climate change.

Ancient meteorite site on Earth could reveal new clues about Mars' past

Wed, 02/26/2020 - 21:21
Scientists have devised new analytical tools to break down the enigmatic history of Mars' atmosphere -- and whether life was once possible there. It could help astrobiologists understand the alkalinity, pH and nitrogen content of ancient waters on Mars, and by extension, the carbon dioxide composition of the planet's ancient atmosphere.

Motley crew: Rust and light a possible answer to the conundrum of hydrogen fuel production

Wed, 02/26/2020 - 20:13
Production of hydrogen fuel is a key goal towards the development of sustainable energy practices, but this process does not have feasible techniques yet. Scientists have identified a novel technique of using rust and light to speed up hydrogen production from organic waste solution, a finding that can revolutionize the clean energy industry.

Tropical nations worst hit by climate-related fish shifts

Wed, 02/26/2020 - 16:55
Policymakers will need to step up to the challenges caused by significant shifts in fish species distributions caused by climate change.
