In Mediterranean marble, secrets of the global carbon cycle
(Phys.org) —Scientists at Yale University have clarified how carbon dioxide escapes minerals deep inside Earth and seeps into the planet's atmosphere, a significant step in the planet's natural carbon cycle. ...
Volcanic eruptions may affect oceanic microbial processes
Extensive, explosive volcanic eruptions may disrupt a crucial aspect of the global nitrogen cycle, say researchers who have investigated ash deposits on the ocean floor.
Acid raid, ozone depletion contributed to ancient extinction
Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth's history.
Climate report struggles with temperature quirks (Update)
Scientists working on a landmark U.N. report on climate change are struggling over how to address a wrinkle in the meteorological data that has given ammunition to global-warming skeptics: The heating of ...
A century of human impact on Arctic climate indicated by new models, historic aerosol data
The Arctic is the most rapidly warming region of the globe, but warming has not been uniform and the drivers behind this warming not fully understood even during the 20th century.
Some volcanoes 'scream' at ever-higher pitches until they blow their tops
It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made ...
Glimpse into the future of acidic oceans shows ecosystems transformed
Ocean acidification may create an impact similar to extinction on marine ecosystems, according to a study released today by the University of California, Davis.
From Mars, to volcanoes, ash clouds and chimneystacks: UK spin-out brings space technology to Earth
Technology designed to measure water vapour on Mars is poised for use in a whole host of everyday applications here on Earth from monitoring food production or industrial gas emissions, to surveying volcanic ...
Global cooling as significant as global warming, research shows
A "cold snap" 116 million years ago triggered a similar marine ecosystem crisis to those witnessed in the past as a result of global warming, according to research published today in Nature Geoscience.
Roman seawater concrete holds the secret to cutting carbon emissions
The chemical secrets of a concrete Roman breakwater that has spent the last 2,000 years submerged in the Mediterranean Sea have been uncovered by an international team of researchers led by Paulo Monteiro ...
Study finds mixed views on use of aerosols to limit climate change
Few members of the UK public are comfortable with the idea of injecting aerosols high into the atmosphere to help slow down climate change, a study has found.
Io's volcanism controls Jupiter's magnetospheric activity
Jupiter's volcanic moon Io spews out volcanic gas, which reaches its atmosphere and becomes ionized, forming what is known as the Io plasma torus. This plasma torus can interact with Jupiter's magnetosphere, ...
First satellite detection of volcanogenic carbon monoxide
Measuring and tracking the gases that vent from an erupting volcano is a project wrought with potential dangers and difficulties. On the ground measurements place researchers in harm's way, as do airborne sampling surveys. ...
Have Venusian volcanoes been caught in the act?
(Phys.org)—Six years of observations by ESA's Venus Express have shown large changes in the sulphur dioxide content of the planet's atmosphere, and one intriguing possible explanation is volcanic eruptions.
