Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new University of Alaska Fairbanks-led study.
Researchers have found declines in the number and diversity of bird populations at nine sites surveyed in northern New Mexico, where eight species vanished over time while others had considerably dropped.
University of Melbourne researchers have developed a software tool that uses applied mathematics and big data analytics to predict the boundary of where a landslide will occur, two weeks in advance.
A new study of the tools used to create Easter Island's giant statues hints at a society in which people collaborated and shared information.
Scientists synchronously incorporated the schemes of anthropogenic water regulation, groundwater lateral flow and the movement of soil frost and thaw fronts into a land surface model, which is then named the Land Surface Model for Chinese Academy of Sciences (CAS-LSM). Results suggested that CAS-LSM is a potential tool for studying land surface processes.
There are many factors that play a role in whether or not it rains, and new research from the University of Arizona shows that human activity may be one of them.
Researchers at Syracuse University are looking to the geologic past to make future projections about climate change. Their research focuses on the ancient Tethys Ocean (site of the present-day Mediterranean Sea) and provides a benchmark for present and future climate and ocean models.
Volatiles -- such as water, carbon dioxide and the noble gases -- come out of the earth's interior through volcanism and may be injected into the mantle from the atmosphere, a pair of processes called mantle degassing and regassing. The exchange controls the habitability of the planet. This transport could not have begun much before 2.5 billion years ago, according to new research that also establishes a range of dates during which the Earth shifted to a net regassing regime.
A study published today in Nature revealed that turning up the heat accelerates spring greening in mature trees, shrubs and mosses and delays fall color change. The research team used direct observation and digital repeat photography to measure plant greenness over three years at the Spruce and Peatland Responses Under Changing Environments study, a unique ecosystem-scale experiment constructed and operated by DOE's Oak Ridge National Laboratory.
Researchers from EPFL and the Ecole Normale Supérieure in Paris have found that the presence of pressurized fluid in surrounding rock can reduce the intensity of earthquakes triggered by underground human activities like geothermal energy production.
