Study finds sinking tundra surface unlikely to trigger runaway permafrost thaw
Oak Ridge National Laboratory scientists set out to address one of the biggest uncertainties about how carbon-rich permafrost will respond to gradual sinking of the land surface as temperatures rise. Using a high-performance computer simulation, the research team found that soil subsidence is unlikely to cause rampant thawing in the future.
Study led by NUS researchers reveals climate change increases fluvial sediment in the high mountains of Asia
To examine the impact of a warmer and wetter climate in High Mountain Asia, Professor Lu Xixi and Dr Dongfeng Li from the Department of Geography at the National University of Singapore (NUS) Faculty of Arts and Social Sciences led an international team of researchers to conduct a new analysis of observations of headwater rivers in the area. The study revealed that fluvial sediment loads have been increasing substantially, even much faster than river water discharge. This has important implications for water quality, hydropower development and maintenance, and for the riverine carbon cycle.
George Washington University Experts Available for Interviews on Climate Change, Air Pollution and Sustainability
WASHINGTON (April 16, 2021) — For Earth Day 2021, President Joe Biden has invited 40 world leaders to take part in a virtual summit to focus on solutions for climate change and other environmental problems. The George Washington University has experts who…
UNH Receives NSF Grant to Research Carbon Interactions in Thawing Arctic
The University of New Hampshire will lead research as part of a $1.5 million award from the National Science Foundation to better understand how interactions between plants, microbes and soil minerals in permafrost, a subsurface layer of frozen soil covering a fourth of the Northern Hemisphere, stimulate the release of carbon which adds to the warming Arctic.
UNH Collaborates with 13 Universities to Understand Climate Change and Ecosystems
The University of New Hampshire is one of 14 universities from around the globe that have collectively been awarded $12.5 million by the National Science Foundation (NSF) to launch a new Biology Integration Institute (BII), called EMERGE, which will focus on better understanding ecosystem and climate interactions—like the thawing of the Arctic permafrost—and how they can alter everything from the landscape to greenhouse gases.
UNH Researchers Find Wildfires Can Alter Arctic Watersheds for 50 Years
Climate change has contributed to the increase in the number of wildfires in the Arctic where it can dramatically shift stream chemistry and potentially harm both ecosystems and humans. Researchers at the University of New Hampshire have found that some aftereffects, like decreased carbon and increased nitrogen, can last up to five decades and could have major implications on vital waterways.
