By adding highly accurate radiocarbon dating of soil to standard Earth system models, environmental scientists from the University of California, Irvine and other institutions have learned a dirty little secret: The ground will absorb far less atmospheric carbon dioxide this century than previously thought.Researchers used carbon-14 data from 157 sample site […]
In a new study that upends the way ornithologists think about a young bird’s diet – but won’t shock parents used to scanning the nutritional profile of their children’s food – Cornell researchers have found that when it comes to what chicks eat, quality trumps quantity.In recent decades, many aerial insectivores, such as tree swallows, have undergone steep p […]
The same hotspot in Earth's mantle that feeds Iceland's active volcanoes has been playing a trick on the scientists who are trying to measure how much ice is melting on nearby Greenland.According to a new study in the journal Science Advances, the hotspot softened the mantle rock beneath Greenland in a way that ultimately distorted their calculatio […]
New research published Monday (Sept. 19) in the journal Nature Climate Change by researchers at Aarhus University in Denmark and the University of Wisconsin-Madison illuminates where and why novel species combinations are likely to emerge due to recent changes in temperature and precipitation. The study includes global maps of novelty that offer testable pre […]
How will we feed our growing population in the face of an increasingly extreme climate? Many experts suggest the answer lies in breeding novel crop varieties that can withstand the increases in drought, heat, and extreme rainfall events predicted in the not-too-distant future. But breeding is only part of the equation, according to new research from the Univ […]

Arctic sea ice extent shrank to 1.6 million square miles earlier this month — tying 2016 with 2007 as the second lowest sea ice minimum since satellite records began. The lowest year remains 2012. The new measurements follow a decades-long trend of declining sea ice extent in the Arctic as global temperatures rise.
