The downward trajectory of plant and animal diversity constitutes a key issue of the Anthropocene. Whether diversity is changing also in the world of microbes is unknown, however -- a "profound ignorance" -- because the importance of these microorganisms maintain Earth's habitability. A paper published today frames the rate of change of microbial biodiversity as an important question on which progress is possible.
A team of researchers from Potsdam and Berlin has identified requirements for a dynamic, long-term carbon price pathway to reduce the demand for CO2 removal technologies and thus effectively limit long-term risks. The approach minimizes governance and sustainability concerns by proposing a market-based and politically feasible approach.
One consequence of the coronavirus pandemic has been global restrictions on mobility. This, in turn, has had an effect on pollution levels in the atmosphere. Researchers from across the world are using this unique opportunity to take measurements, collect data, and publish studies. An international team led by Forschungszentrum Jülich's Institute of Climate and Energy Research - Troposphere has now published a comprehensive review providing an overview of results up to September 2020.
Is it possible to simultaneously address the increase of the concentration of carbon dioxide (CO2) in the atmosphere and the resulting acidification of the oceans? The research of the project DESARC-MARESANUS, a collaboration between the Politecnico di Milano and the CMCC Euro-Mediterranean Center on Climate Change Foundation, explores the feasibility of this process, its chemical and environmental balance, and the benefits for the marine sector, focusing on the Mediterranean basin.
The April snow falling on fruit blossoms in Europe these days may be directly connected to the loss of the sea ice in the Barents Sea in the Arctic. That was definitely the case in 2018 when the sudden cold spell known as "Beast from the East" descended on the mid-latitudes of the continent, a new study in Nature Geoscience shows.
Researchers at the University of British Columbia have discovered three liquid phases in aerosol particles, changing our understanding of air pollutants in the Earth's atmosphere. While aerosol particles were known to contain up to two liquid phases, the discovery of an additional liquid phase may be important to providing more accurate atmospheric models and climate predictions.
To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do to rule out non-biological chemical processes.
For the first time, researchers have been able to obtain data from underneath Thwaites Glacier, also known as the "Doomsday Glacier". They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow.
Tracking carbon dioxide levels indoors is an inexpensive and powerful way to monitor the risk of people getting COVID-19, according to new research from CIRES and the University of Colorado Boulder. In any given indoor environment, when excess CO2 levels double, the risk of transmission also roughly doubles, two scientists reported this week in Environmental Science & Technology Letters.
Astronomers have found evidence that the first exoplanet that was identified transiting its star could have migrated to a close orbit with its star from its original birthplace further away.
