Earth in the News
The latest reports of natural disasters and scientific discoveries about the Earth.
The world's 'best of the last' tropical forests are at significant risk of being lost, according to a new article. Of these pristine forests that provide key services -- including carbon storage, prevention of disease transmission and water provision -- only a mere 6.5 percent are formally protected.
A new study supports predictions that the Arctic could be free of sea ice by 2035.
Corals and cave carbonates can reveal the temperatures that prevailed at the Earth's surface at the time they formed. An international team of geoscientists has developed a new method that makes it possible to identify whether the composition of these deposits was exclusively controlled by temperature, or if the formation process itself exerted an additional control. The new method allows scientists to determine past Earth surface temperatures more reliably.
A new publication on the impacts of deep-seabed mining by 13 prominent deep-sea biologists seeks to dispel scientific misconceptions that have led to miscalculations of the likely effects of commercial operations to extract minerals from the seabed.
A new study of more than 1,000 years of North American droughts and global conditions found that forecasting a lack of precipitation is rarely straightforward.
A key component of the Gulf Stream has markedly slowed over the past century -- that's the conclusion of a new research paper.
Climate researchers have found a link between hurricanes that form in the Atlantic Ocean - and threaten the United States - and a weather system in East Asia. A jet stream originating in East Asia carries an atmospheric wave to the Atlantic Ocean that affects wind shear - a key element in whether tropical storms develop.
A group of researchers has discovered why the western subarctic Pacific Ocean, which accounts for only 6 percent of the world's oceans, produces an estimated 26 percent of the world's marine resources.
Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists now report on a hydrothermal mechanism that could have promoted the process.
A new study warns that even with some lockdown measures staying in place to the end of 2021, without more structural interventions global temperatures will only be roughly 0.01°C lower than expected by 2030. However, the study estimates that including climate policy measures as part of an economic recovery plan with strong green stimulus could prevent more than half of additional warming expected by 2050 under current policies.
A novel connection between primordial organisms and complex life has been discovered, as new evidence sheds light on the evolutionary origins of the cell division process that is fundamental to complex life on Earth.
Researchers report that anthropogenic sources of carbonyl sulfide (OCS), not just oceanic sources, account for much of the missing source of OCS in the atmosphere. Their findings provide better context for estimates of global photosynthesis (taking up CO2) using OCS dynamics.
One million years ago, the extinction of large-bodied plant-eaters changed the trajectory of life on Earth. The disappearance of these large herbivores reshaped plant life, altered fire regimes across Earth's landscapes, and modified biogeochemical cycling in such a way that Earth's climate became slightly colder.
A new way to treat acid mine drainage (AMD) could help transform the environmental pollution problem into an important domestic source of the critical rare earth elements needed to produce technology ranging from smart phones to fighter jets, according to scientists.
A new study which provides a global estimate of rock cover on the Earth's glaciers has revealed that the expanse of rock debris on glaciers, a factor that has been ignored in models of glacier melt and sea level rise, could be significant.
Subsurface cavities created by lava on Mars and the Moon could provide a shield against cosmic radiation, new research suggests.
A new analysis of sandstones from Antarctica indicates there may be important links between the generation of mountain belts and major transitions in Earth's atmosphere and oceans. A team of researchers analyzed the chemistry of tiny zircon grains commonly found in the Earth's continental rock record to determine their ages and chemical compositions.
Car users from the world's least affluent cities are exposed to a disproportionate amount of in-car air pollution because they rely heavily on opening their windows for ventilation, a new study finds.
Geologists have discovered how carbon-rich molten rock in the Earth's upper mantle might affect the movement of seismic waves.
Experts have reconstructed the depth of the Southern Ocean at key phases in the last 34 million years of the Antarctic's climate history.
