Sentences with phrase «reflective particles»

Should we launch reflective particles into the upper atmosphere?

There are several variations on the so - called solar geoengineering theme, but they all have the same end - goal: using aerosols to blanket our atmosphere with reflective particles in order to quickly lower global temperatures.

As they note, the idea has been around for ages; a 1965 report «nonchalantly proposed dealing with the results by dumping vast quantities of reflective particles into the oceans, to increase the amount of sunlight reflected into space.»

Attempts to reverse the impacts of global warming by injecting reflective particles into the stratosphere could make matters worse, say researchers.

Now, they've discovered it was due to reflective particles used to test military radar

Proposals include artificially brightening clouds, increasing the reflectivity of surface - level planetary features, or depositing reflective particles in the earth's upper atmosphere.

Instead they considered one idea: «spreading very small reflective particles» over about five million square miles of ocean, so as to bounce about 1 percent more sunlight back to space — «a wacky geoengineering solution,» Keith says, «that doesn't even work.»

Look for «brightening» formulas that contain light reflective particles to hide dark circles.

Reflective particles work to blur any imperfections, while the darker shade masks them.

Even though average global temperatures can certainly be lowered by feeding reflective particles into the stratosphere — we know this from observations of big volcanic eruptions — regional consequences can't yet be adequately predicted by climate models.

One of the most credible plans involves using reflective particles called aerosols to reflect solar radiation away from the Earth.

To spray reflective particles into the atmosphere.

But at the same time as warming the planet, pollution from coal power plants, airplanes and other sources of industrial soot, aerosols and sulfates are artificially cooling the planet by filling the atmosphere with reflective particles, a process known as global dimming.

In November, Smith held a hearing on geo - engineering, a suite of climate change techno - fixes that range from the plausibly doable but potentially catastrophic (spraying a bunch of reflective particles into the stratosphere) to straight up scifi ideas, like throwing solar - reflecting mirrors up into space.

Geoengineering, the use of human technologies to alter Earth's climate system — such as injecting reflective particles into the upper atmosphere to scatter incoming sunlight back to space — has emerged as a potentially promising way to mitigate the impacts of climate change.

It nonchalantly proposed dealing with the results by dumping vast quantities of reflective particles into the oceans, to increase the amount of sunlight reflected into space.

From the CAT data, the scientists had a three - dimensional, 15 - centimeter - long epoxy boxfish model built, which they dunked in a water tunnel seeded with reflective particles.

As water flowed over the model, the team illuminated the reflective particles with lasers and videotaped them to track the water's motions.

In some of the extrasolar, Jupiter - sized planets that tread short, circular orbits, Kane explained, this phenomenon does appear to strip the atmospheres of reflective particles, making the planets appear «dark.»

Proponents of geoengineering have called for injecting small, reflective particles into the atmosphere to partially block sunlight and cool the earth, just as ash from an erupting volcano does.

David Keith, professor of applied physics at Harvard University, used climate models to suggest that injecting reflective particles into the atmosphere could reduce the amount of sunlight reaching [continue reading...]

Rather, solar radiation management seeks to reduce the amount of radiation that reaches Earth, such as by brightening clouds, injecting reflective particles into the atmosphere or even installing mirrors in space.

We recently looked at problems with a last resort solution to counteract global warming by artificially shading the Earth from sunlight by injecting sulphur or small, reflective particles into the upper atmosphere.

Spreading iron throughout the ocean to promote growth of carbon - sucking plankton, launching heat - protecting shields into orbit and adding sun - reflective particles to the atmosphere are a few solutions that have been floated.
