Greenland Ice Sheet is More Sensitive to Climate Change than Previously Understood

In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland--and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. It was accidentally rediscovered in 2017.

NASA Images Reveal Significant Losses of Forest and Wetlands in Belize

Using NASA satellite images and machine learning, researchers with The University of Texas at Austin have mapped changes in the landscape of northwestern Belize over a span of four decades, finding significant losses of forest and wetlands, but also successful regrowth of forest in established conservation zones that protect surviving structures of the ancient Maya.

Increase in Global Warming Threatens Habitats of Freshwater Fish Species

The habitats of freshwater fish species are threatened by global warming, mainly due to rising water temperatures. A 3.2-degree Celsius increase in global mean temperature would threaten more than half of the habitat for one third of all freshwater fish species.

Study Reveals Extent and Impact of Climate Change on Tropical Mountains

The tropics are known to drive atmospheric and ocean circulation in the world, and hence have a crucial role to play in interpreting both the past and upcoming climate change.

New Insights on the Fate of Spilled Oil in the Marine Environment

A new study lead by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science demonstrates that under realistic environmental conditions oil drifting in the ocean after the DWH oil spill photooxidized into persistent compounds within hours to days, instead over long periods of time as was thought during the 2010 Deepwater Horizon oil spill.

Researchers Receive NASA Grant to Assess Changes in Tropical Biodiversity Hotspot

The Madre de Dios River watershed in southeastern Peru is a tropical biodiversity hotspot in the Amazon and home to uncontacted Indigenous peoples, which has come under threat in recent years due to an expansion in artisanal and small-scale gold mining.

Study Shows Climate Change-Related Population Declines in Tropical Birds

The mountain forests of Tanzania are more than 9,300 miles away from Salt Lake City, Utah. But, as in eastern Africa, the wild places of Utah depend on a diversity of birds to spread seeds, eat pests and clean up carrion. Birds keep ecosystems healthy. So if birds in Tanzania are in trouble in a warming climate, as found in a recent study by University of Utah researchers, people in Utah as well as in the African tropics should pay attention.

New Insights into the Role of Legume Trees in Supporting Tropical Forest Growth

Researchers have found that nitrogen-fixing legume trees can support themselves and surrounding trees not only with increased access to nitrogen, but with other key nutrients through enhanced mineral weathering.
