High-speed FM-AFM and simulation reveal atomistic dissolution processes of calcite in water
23 hours ago
Calcite is one of the most abundant components of the Earth's crust, constituting the largest carbon reservoir in the global carbon cycle. Thus, large-scale dissolution of calcite would have enormous impact on the weather, ...
Link identified between continental breakup, volcanic carbon emissions and evolution
Jul 21, 2017
Researchers have found that the formation and breakup of supercontinents over hundreds of millions of years controls volcanic carbon emissions. The results, reported in the journal Science, could lead to a reinterpretation ...
Scientists shed light on carbon's descent into the deep Earth
Jul 19, 2017
Examining conditions within the Earth's interior is crucial not only to give us a window back to Earth's history but also to understand the current environment and its future.
Diatoms have sex after all, and ammonium puts them in the mood
Jul 07, 2017
New research shows a species of diatom, a single-celled algae, thought to be asexual does reproduce sexually, and scientists learned it's a common compound - ammonium - that puts the ubiquitous organism in the mood.
How much carbon can polar seafloor ecosystems store?
Jun 27, 2017
One of the best-known impacts of climate change is the loss of sea ice in the Arctic, but also in parts of the Antarctic: the poles are increasingly turning from white to blue. However, in the shallow seas near continental ...
Alpine streams produce more CO2 after a warm winter
Jun 09, 2017
An EPFL study has for the first time measured the impact of climate change on alpine streams, and the results are quite worrying: after a low-snow winter, these streams release more carbon dioxide than they absorb.
Tiny shells indicate big changes to global carbon cycle
May 25, 2017
Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis.
High-tech rainforest map brings climate and conservation efforts into sharp relief
May 23, 2017
Outside of the Amazon, the rainforests of central Africa are the largest in the world. They contain huge amounts of carbon and wildlife—two items at the top of the list for those looking to protect the planet's health.
Scientists begin to unlock secrets of deep ocean color from organic matter
May 17, 2017
About half of atmospheric carbon dioxide is fixed by ocean's phytoplankton, mainly picocyanobacteria, through a process called photosynthesis. Picocyanobacteria are tiny, unicellular microorganisms that are abundant and widely ...
Dams are major driver of global environmental change
May 17, 2017
Water reservoirs created by damming rivers could have significant impacts on the world's carbon cycle and climate system that aren't being accounted for, a new study concludes.
