(PhysOrg.com) -- A mysterious high-altitude layer of sulphur dioxide discovered by ESA's Venus Express has been explained. As well as telling us more about Venus, it could be a warning against injecting our atmosphere with ...
New research, led by the University of Southampton, has questioned the role played by ocean acidification, produced by the asteroid impact that killed the dinosaurs, in the extinction of ammonites and other planktonic calcifiers ...
Volcanic eruptions across a vast area of what is now Western Australian and the Northern Territory 510 million years ago caused the first known mass extinction of complex life forms.
With its exploding urban population burning ever more coal and wood, Africa could contribute as much as 55 percent of the world's particle pollutants by 2030, a study said Tuesday.
According to the theory, small clusters of molecules in the atmosphere have difficulty growing large enough to act as "cloud condensation nuclei" on which water droplets can gather to make our familiar low-altitude clouds. ...
Medieval chronicles have given an international group of researchers a glimpse into the past to assess how historical volcanic eruptions affected the weather in Ireland up to 1500 years ago.
(Phys.org) —Scientists have discovered further evidence for the existence of new molecules in the atmosphere that have the potential to off-set global warming by reacting with airborne pollutants.
(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.
(Phys.org)—A low-cost new material that could lead to innovative technologies to tackle global warming has been discovered by scientists at The University of Nottingham.
(PhysOrg.com) -- New research from the University of Leeds shows that a large-scale volcanic eruption in southern Iceland, similar to the Laki eruption in 1783, could result in widespread air pollution across Europe.
