Today, only the eldest inhabitants of the Danube Delta recall that, in the past, you could skate on the river practically every winter; since the second half of the 20th century, Europe's second-largest river has only rarely frozen over.
Sharon Browning of the University of Washington and colleagues developed a method to estimate historical effective population size, which is the number of individuals who pass on their genes to the next generation, to reveal the shifting demographic history of US populations during the last several thousand years. They report their findings in a new study published May 24, 2018, in PLOS Genetics.
The oldest ice core so far provides 800,000 years of our planet's climate history. A field survey in Antarctica has pinpointed a location where an entire million years of undisturbed ice might be preserved intact.
A new study shows the Earth's climate would increase by 4 degrees Celsius, compared to pre-industrial levels, before the end of 21st century. The study also projects precipitation changes in association with a 4 degrees Celsius global warming above the pre-industrial period using the available RCP8.5 experiments of CMIP5 models.
ANU archaeologist Dr. Catherine Frieman unearths an intact 4,000-year-old human cremation in clay pottery urn on a Cornish site she discovered by accident.
A new study of marine fossils from Antarctica, Australia, New Zealand and South America reveals that one of the greatest changes to the evolution of life in our oceans occurred more recently in the Southern Hemisphere than previously thought. The results are published today in the journal Communications Biology.
A new global, satellite-based study of Earth's freshwater found that Earth's wet areas are getting wetter, while dry areas are getting drier. The data suggest this pattern is due to many factors, including human water management practices, human-caused climate change and natural climate cycles. The NASA-led research team used 14 years of observations from the Gravity Recovery and Climate Experiment (GRACE) mission to track global trends in freshwater in 34 regions around the world.
Contrary to previous analyses, research published by Michigan State University shows that projected changes in temperature and humidity will not lead to greater water use in corn. This means that while changes in temperatures and humidity trend as they have in the past 50 years, crop yields can not only survive -- but thrive.
Clues from some unusual Arizona rocks pointed Rice University scientists toward a discovery -- a subtle chemical signature in rocks the world over -- that could answer a long-standing mystery: What stole the iron from Earth's continents?
Climate change will force hundreds of ocean fish and invertebrate species, including some of the most economically important to the United States, to move northward, disrupting fisheries in the United States and Canada, a Rutgers University-led study reports. The study, published today in the journal PLOS ONE, covers the North American continental shelfs on the Pacific and Atlantic coasts.
