GeoCarb—a new view of carbon over the Americas
Jan 12, 2018
A new NASA Earth science mission in the early stages of design may achieve a transformational advance in our understanding of the global carbon cycle by mapping concentrations of key carbon gases from a new vantage point: ...
The view from near-earth orbit—scientist helps set satellites' priorities
Jan 08, 2018
The "eye in the sky" has become a major part of research for segments of the scientific community. But how should it be trained?
Real world native biocrusts: Microbial metabolism
Jan 04, 2018
Arid lands, which cover some 40 percent of the Earth's terrestrial surface, are too dry to sustain much in the way of vegetation. But far from being barren, they are home to diverse communities of microorganisms—including ...
Human impacts on forests and grasslands much larger and older than previously assumed
Dec 21, 2017
Human biomass utilization reduces global carbon stocks in vegetation by 50%, implying that massive emissions of CO2 to the atmosphere have occurred over the past centuries and millennia. The contribution of forest management ...
Abundant enzyme in marine microbes may be responsible for production of ocean methane
Dec 07, 2017
Industrial and agricultural activities produce large amounts of methane, a greenhouse gas that contributes to global warming. Many bacteria also produce methane as a byproduct of their metabolism. Some of this naturally released ...
From Alaska to Amazonia—first global maps of traits that drive vegetation growth
Dec 01, 2017
Detailed global maps of key traits in higher plants have been made available for the first time, thanks to work led by researchers from the University of Minnesota's (UMN) College of Food, Agriculture and Natural Resource ...
Southern Ocean drives massive bloom of tiny phytoplankton
Nov 30, 2017
Scientists have uncovered the ocean conditions that support a massive summertime bloom of algae that spans 16 percent of the global ocean. Known as the Great Calcite Belt, this dense group of a microscopic phytoplankton, ...
Radar satellites able to measure water stress in trees
Nov 30, 2017
Radar technology in space can be used to measure how 'thirsty' plants and crops are. This could play a key role in improving our understanding of how ecosystems and the water and carbon cycles interrelate. In theory, we have ...
Dark ocean bacteria discovered to play large role in carbon capture
Nov 27, 2017
Marine bacteria that live in the dark depths of the ocean play a newly discovered and significant role in the global carbon cycle, according to a new study published in Science.
Why are global CO2 emissions on the rise again?
Nov 22, 2017
Illinois atmospheric scientist Atul Jain was among the many scientists worldwide who contributed data to the Global Carbon Budget 2017, released Nov. 13. Jain talked about this year's findings with News Bureau physical sciences ...
