Sentences with phrase «sulfur aerosols cool»

White sulfur aerosols cool the climate; black carbon soot warms the climate.

Not exact matches

Besides SSCE, scientists have also been investigating stratospheric sulfur injections — firing sun - reflecting aerosols into the air, similar to the cooling effect after a volcanic eruption — and cirrus cloud thinning, where you thin the top level of clouds, which have a warming effect on the planet.

Turning greenhouse gases into cooling aerosols The team then mixed the intermediates with various compounds, like sulfur and nitrogen greenhouse gases, to see how fast they reacted.

Reducing sulfur emissions also stops the cooling impact of sulfate aerosols.

In reality, there are a host of both natural and anthropogenic aerosols, ranging from sea salt (the major source of cloud nuclei over the ocean) to biogenic aerosols from forests (the «smoke» of the Great Smoky Mountains of the Eastern US) to partially burnt organic materials (the «brown cloud» over Asia, generally absorptive / warming) to various sulfur compounds (generally reflective / cooling).

The two main types, she says, are solar radiation management, which mostly refers to injecting sulfur aerosols into the stratosphere to reflect sunlight and, hence cool the Earth; and carbon dioxide removal, which is best illustrated by direct air capture — machines that take carbon dioxide out of the air and store it underground.

In response, the IPCC added a cooling factor to its models of the atmosphere, consisting of tiny aerosol particles produced by the emission of sulfur dioxide from electric power plants.

We always thought that — apart of course from soot [15 % of climate warming]-- such aerosol pollution creates cooling — as in the case of Chinese sulfur pollution and the Asian (Indian) brown cloud — and that air quality measures over recent decades in North America and Europe are now actually a major cause of increased warming speeds there — as the actual temperature catches up on the «CO2 baseline».

The basic science underlying this idea is pretty solid — large volcanic eruptions blast SO2 into the stratosphere where the sulfur aerosols naturally cool the globe for a few years.

Volcanoes blast sulfur dioxide aerosols into the stratosphere, where they cool Earth by blocking some of the sun's solar radiation and reflecting it back into space.

In this context, they settled on sulfur dioxide aerosols and black carbon as cooling agents (which they are, at least to some extent).
