Latest Stratospheric sulfur aerosols Stories
A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable.
UI researchers develop technique to help pollution forecasters see past clouds
An international team of researchers have found that even small volcanic eruptions can lead to a cooler climate if they coincide with weather systems such as monsoons, which boost aerosols produced by eruptions high into the atmosphere affecting global temperatures.
As the reality and the impact of climate warming have become clearer in the last decade, researchers have looked for possible engineering solutions – such as removing carbon dioxide from the atmosphere or directing the sun's heat away from Earth – to help offset rising temperatures.
Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing the Earth to get hotter and hotter.
Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in cool and relatively dry regions, such as Israel in winter, but also can increase rain and the intensity of severe storms in warm and moist regions or seasons, such as the eastern half of the US during summer.
Many of the particles in the atmosphere are produced by the natural world, and it is possible that plants have in recent decades reduced the effects of the greenhouse gases to which human activity has given rise.
A Yale study examining the impact of aviation on climate change found that removing sulfur from jet fuel cools the atmosphere.
Our understanding of how clouds form may need to be revised, according to new research published in the journal Nature.
Supercomputer simulations by University of Washington researchers outline the potential risks and benefits of geoengineering.
