Decomposition of rhizospheric soil organic carbon is more sensitive to climate warming than non-rhizosphere carbon

Credit: CC0 Public Domain The rhizosphere is the narrow region where plant roots and the soil interact vigorously and intensive microbial metabolism occurs. The properties of rhizosphere soil are usually different from that of non-rhizosphere soil. This is called rhizosphere effects (REs). The decomposition of rhizospheric soil organic carbon (SOC) plays an important role in… Continue reading Decomposition of rhizospheric soil organic carbon is more sensitive to climate warming than non-rhizosphere carbon

When variations in Earth’s orbit drive biological evolution

Coccolithophores, an important constituent of the plankton, evolved following the rhythm of Earth’s orbital eccentricity. Credit: Luc Beaufort / CNRS / CEREGE Coccolithophores are microscopic algae that form tiny limestone plates, called coccoliths, around their single cells. The shape and size of coccoliths varies according to the species. After their death, coccolithophores sink to the… Continue reading When variations in Earth’s orbit drive biological evolution

Physics-informed deep learning to assess carbon dioxide storage sites

This diagram shows the modeling framework for the physics-constrained deep learning algorithm. Credit: Parisa Shokouhi Pumping carbon dioxide underground may help combat the warming of the atmosphere but finding appropriate underground sites that could safely serve as reservoirs can be complicated. To address this complexity, a Penn State-led research team combined an artificial intelligence technique with… Continue reading Physics-informed deep learning to assess carbon dioxide storage sites

New aerostat realizes stable measurement of multiple atmospheric parameters

Schematic diagram of new method for measuring vertical profiles of multiple atmospheric parameters carried by an aerostat. Credit: SHAO Shiyong Atmospheric parameter sounding is a necessary input parameter and a reference for atmosphere and environmental protection departments to master the atmospheric conditions, conduct atmosphere and air quality forecasting and formulate corresponding emergency control strategies. A… Continue reading New aerostat realizes stable measurement of multiple atmospheric parameters

Sentinel-6 Mission Returning Most Precise Data Ever on Sea Level

The Copernicus Sentinel-2 mission takes us over the Tarawa Atoll in the Republic of Kiribati – a remote Pacific nation threatened by rising seas. The Republic of Kiribati is an independent island nation consisting of some 33 atolls near the equator in the central Pacific. The islands are spread over approximately 3.5 million sq km… Continue reading Sentinel-6 Mission Returning Most Precise Data Ever on Sea Level

Earth’s Early Magma Oceans Detected in 3.7 Billion Year-Old Greenland Rocks

By Helen M. Williams, University of Cambridge November 30, 2021 4 billion years ago, the Earth was composed of a series of magma oceans hundreds of kilometers deep. Earth hasn’t always been a blue and green oasis of life in an otherwise inhospitable solar system. During our planet’s first 50 million years, around 4.5 billion… Continue reading Earth’s Early Magma Oceans Detected in 3.7 Billion Year-Old Greenland Rocks

Historical land dispossession makes Native Americans more vulnerable to climate change

Indigenous nations across the United States have lost 98.9% of their historical land base, and more than 42% of tribes from the historical period through modern day do not possess federally recognized land. And, those who do still possess land tend to have about 2.6% of their estimated historical area. Because of this, Native Americans… Continue reading Historical land dispossession makes Native Americans more vulnerable to climate change

Arctic rainfall could dominate snowfall earlier than expected: study

Credit: CC0 Public Domain Rainfall could start replacing snowfall in the Arctic decades sooner than previously thought, a study found Tuesday, warning the change caused by global warming could have effects beyond the region. The Arctic is warming much faster than the rest of the planet, melting sea ice and adding moisture to the air… Continue reading Arctic rainfall could dominate snowfall earlier than expected: study
