Sentences with phrase «cirrus cloud thinning»

On top of this, large questions remain over how cirrus cloud thinning could affect other aspects of the climate system, such as atmospheric circulation, the paper concludes:

«Only after these questions are addressed could one move further to explore the costs and feasibility of cirrus cloud thinning.»

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.

Not exact matches

«As soon as the contrails stop being these pencil - thin lines in the sky, it becomes difficult to differentiate natural cirrus from aviation - induced clouds,» said MacKenzie.

In addition, around the tropopause the air is close to saturation with water and a small increase of vapour from aircraft can create wide expanses of thin cirrus clouds that cause even stronger warming.

Even more, the Davies paper only looks at 10 years of data (with sampling times at just one time in the local morning) and doesn't capture some clouds such as thin cirrus that may also be important.

The overall effect of the high thin cirrus clouds then is to enhance atmospheric greenhouse warming.

The high, thin cirrus clouds in the Earth's atmosphere act in a way similar to clear air because they are highly transparent to shortwave radiation (their cloud albedo forcing is small), but they readily absorb the outgoing longwave radiation.

In the case of thin cirrus overlying low clouds, 3I will determine the effective cloud amount of the cirrus, whereas ISCCP's information from the visible channel includes the lower cloud.

Another approach involves thinning of high cirrus clouds, which are involved in regulating the amount of heat that escapes from the planet to outer space.

The overall heat - trapping effect of cirrus clouds is so large that it exceeds that of human - released CO2, says Prof Ulrike Lohmann, an atmospheric scientist from ETH Zurich who recently published a review on cloud thinning in Science.

Seeding the atmosphere with dust would paradoxically thin out cirrus clouds, Lohman said.

Thin, icy cirrus clouds are poor sunshields but very efficient insulators that trap energy rising from the Earth's warmed surface.

Richard Lindzen, on page 19 of his new new paper titled «Can thin cirrus clouds in the tropics provide a solution to the Faint Young Sun paradox?»
