Earth in the News
The latest reports of natural disasters and scientific discoveries about the Earth.
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.
Experts have developed a new way of mining data from climate data sets that is more self-contained than traditional tools. The methodology brings out commonalities of data sets without as much expertise from the user, allowing scientists to trust the data and get more robust -- and transparent -- results.
New research not only implies a link between catastrophic volcanic eruptions and landslides, but also suggests that landslides are the trigger. At the heart of Tenerife and standing almost 4 km high, Teide is one of the largest volcanoes on Earth. Over a period of several hundred thousand years, the previous incarnations of Teide have undergone a repeated cycle of very large eruptions, collapse, and regrowth.
The volume of hydraulic fracturing fluid and the location of well pads control the frequency and occurrence of measurable earthquakes, new research has found.
Researchers have used high-tech tools to more precisely view where these cleared sites were and how much lasting impact they had on the rainforest in the Amazon Basin in South America.
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.
While some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet's animals and plants experiencing the most stress.
A research team has mapped the temperature and viscosity of earth's lower crust for the first time.
Uncertainty surrounding the extent of future climate change could be dramatically reduced by studying year-on-year global temperature fluctuations, new research has shown.
A new study shows that sampling headwaters where streams form can identify which landscapes are resilient enough to handle the rigors of farming and which are vulnerable to leaching toxic residue into waterways.
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 are reviewing the potential settings where a global reference section for the Anthropocene might be searched.
There is an enduring myth that large earthquakes tend to happen during certain phases of the Moon or at certain times during the year. But a new analysis confirms that this bit of earthquake lore is incorrect.
Scientists have made a model to map out the phases in which silica (SiO2) transforms into coesite, by analyzing how the inelastic scattering of light among molecules changes according to pressure variation.
Researchers have made significant efficiency improvements to the technology used to generate solar fuels. This involves the direct conversion of energy from sunlight into a usable fuel (in this case, hydrogen). Using only earth-abundant materials, they developed the most efficient conversion method to date. The trick was to decouple the site where sunlight is captured from the site where the conversion reaction takes place.
Biochemists report a bacterial, iron-only nitrogenase pathway for methane formation.
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.
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.
Scientists examined and analyzed hundreds of pelican spiders both in the field in Madagascar and through study of pelican spiders preserved in museum collections. Their analysis sorted the spiders studied into 26 different species -- 18 of which have never before been described. The new species add to scientists' understanding of Madagascar's renowned biodiversity, and will help scientists investigate how pelican spiders' unusual traits have evolved and diversified over time.
A detailed study of blue salt crystals found in two meteorites that crashed to Earth -- which included X-ray experiments found that they contain both liquid water and a mix of complex organic compounds including hydrocarbons and amino acids.
