Earth in the News
The latest reports of natural disasters and scientific discoveries about the Earth.
Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.
Biodiversity losses from deep-sea mining are unavoidable and possibly irrevocable, an international team of scientists, economists and lawyers argue. They say the International Seabed Authority, which is responsible for regulating undersea mining in areas outside national jurisdictions, must recognize the risk and communicate it clearly to member states and the public to spur discussions as to whether deep-seabed mining should proceed, and if so, what safeguards are needed to minimize biodiversity loss.
The ongoing deforestation around the fringes of the Amazon may have serious consequences for the untouched deeper parts of the rainforest. A new research study shows that it is not only the climate that is adversely affected by deforestation. In fact, the very stability of the ecosystem in the entire Amazon region is altered when deforestation takes place in the outermost regions.
During the last glacial period, within only a few decades the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland -- as indicated by new climate calculations.
Using a combination of satellite and ground data, a research team can map multiple indicators of monkey distribution, including human activity zones as inferred from roads and settlements, direct detections from mosquito-derived iDNA, animal sound recordings, plus detections of other species that are usually found when monkeys are present, such as other large vertebrates.
Giant viruses acquire genes piecemeal from others, researchers have found. The discovery has implications for bioenergy production and environmental cleanup.
There is a clear potential for practical and useful predictions of northwestern European and Arctic climate based on the state of the ocean, new research indicates.
Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.
An international team of scientists recently discovered the role that hot electrons may play in the waves and fluctuations detected by satellites. The results are based on data collected by the Van Allen Probes, twin robotic spacecraft launched by NASA in 2012 to help scientists better understand these belt regions.
An astrophysicists has warned that an asteroid strike is just a matter of time.
Waves deep within the ocean play an important role in establishing ocean circulation, arising when tidal currents oscillate over an uneven ocean bottom. The internal waves generated by this process stir and mix the ocean, bringing cold, deep water to the surface to be warmed by the sun. Investigators now explain how to tell which way internal waves will go. The proposed theory unifies several previously understood explanations of wave propagation.
An analysis of stalagmite records from White Moon Cave in the Santa Cruz Mountains shows that 8200 years ago the California coast underwent 150 years of exceptionally wet and stormy weather. This is the first high resolution record of how the Holocene cold snap affected the California climate.
Three million measurement points in one square kilometer: a world record has now been set in information retrieval from satellite data. Thanks to new algorithms, the researchers succeeded in making four-dimensional point clouds of Berlin, Las Vegas, Paris and Washington, D.C. from images stacks of the TerraSAR-X radar satellite. Next the scientists plan to create four-dimensional models of all cities in the world.
Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new research has found.
Scientists believe they have discovered the reason behind mysterious changes to the climate that saw temperatures fluctuate by up to 15°C within just a few decades during the ice age periods.
Bringing renewable power ‘by wire’ from western China to its power-hungry Eastern cities could have benefits for both local air quality and global climate change, new research has found.
The projected world population by 2056 is 10 billion. If researchers succeed in improving the yield potential of 40 percent of global land area under arid and semi-arid conditions, it will lead to a significant contribution to future food security.
California's earthquake faults continually accumulate stress until they fail in an earthquake. Seismologists studied the impact of the flexing of Earth's crust under the load of winter rains and subsequent unloading during summer drought, and found that the up and down movement of the mountains changes the stresses on the state's faults, making them fail slightly more often as the snows melt and the rivers drain in late summer and early fall.
Volcanologists are gaining a new understanding of what's going on inside the magma reservoir that lies below an active volcano and they're finding a colder, more solid place than previously thought, according to new research.
Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to researchers who used data from instruments placed on the seafloor and in boreholes east of the Japanese coast.
