Throughout the U.S., trees are dying at an astonishing rate. The reasons for the die-off vary from location to location — drought, disease, insects and wildfires – but the root cause in many of these cases is the same: climate change. The epidemic is even threatening the oldest white

The Northwest Passage originated as an unattainable and lethal legend when Europeans arrived in the Americas and longed for an easy sea route across North America. Now, a cruise ship has successfully traversed the route in only a month. It wasn’t until 1906 that Norwegian explorer Roa

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 t

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 deca

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 preci

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 man

Marine ecosystems are responsible for about half of global annual primary production and more than one billion people rely on fish as their primary protein source. Latest studies show that enormous warm water bubbles in the ocean are having a noticeable impact on ecosystems. How shoul

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 Arct

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 bre

This is an issue of global concern. Climate change, urbanization, and resource depletion (more mouths to feed, burn wood in stoves for, graze more cattle for) is still happening at a fast an alarming clip, influencing our planet’s ability to store CO2 emissions, and protect diversity.
