Sentences with phrase «clouds of sulfur»

The problem in the 1980s was that American power plants were sending up vast clouds of sulfur dioxide, which was falling back to earth in the form of acid rain, damaging lakes, forests and buildings across eastern Canada and the United States.

The oceans will boil away and the atmosphere will dry out as water vapor leaks into space, and temperatures will soar past 700 degrees Fahrenheit, all of which will transform our planet into a Venusian hell - scape choked with thick clouds of sulfur and carbon dioxide.

By June of 1992 after a full year the cloud of sulfur gases had completely blanketed the Earth.

Not exact matches

After analyzing this view of a glory on Venus — combining three wavelengths into a false - color image — astronomers were surprised to learn that the planet's clouds aren't pure sulfuric acid after all, but may include iron chloride and pure sulfur.

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.

Maybe we will get to see the moon Io, a hellish world of nonstop sulfur volcanoes, against a backdrop of Jupiter's enormous colored bands of clouds.

Despite its smaller ash cloud, El Chichn emitted more than 40 times the volume of sulfur - rich gases produced by Mt. St. Helens, which revealed that the formation of atmospheric sulfur aerosols has a more substantial effect on global temperatures than simply the volume of ash produced during an eruption.

In addition to ash, the eruptive cloud consisted primarily of vast quantities of sulfur dioxide (SO2), hydrogen chloride (HCl), and hydrogen fluoride gases (HF).

In addition to billowing clouds of ash that likely clouded the world, killed plants, and stymied food chains, vaporized gypsum from the impact contributed to toxic sulfur in the atmosphere.

Toward the end of that year, though, the Pioneer Venus probe entered Venusian orbit — and immediately recorded suspiciously high levels of sulfur dioxide above the clouds.

When these dissolved metals and sulfur meet the oxygen - rich seawater above, they form black metal - sulfide minerals, creating what appear to be clouds of black smoke.

Temperatures at these vents can top 400 degrees Celsius and thick plumes of iron and sulfur cloud the permanently pitch - black waters.

Volcanologist Andrew McGonigle walks through clouds composed of mist, steam, carbon dioxide (CO2), and sulfur dioxide (SO2) on Vulcano, an active volcanic island off the coast of southern Italy.

These same clouds are vital in the movement of large amounts of sulfur from the oceans to land, making the production of DMSP and DMS a critical step in the global sulfur cycle.

Amid clouds of toxic sulfur dioxide gas, he carries heavy loads up a steep, rocky path from the crater floor to the rim, then to a distant weigh - station.

And just as increased algal productivity at sea increases the emission of sulfur gases to the atmosphere, ultimately leading to more and brighter clouds over the world's oceans, so too do CO2 - induced increases in terrestrial plant productivity lead to enhanced emissions of various sulfur gases over land, where they likewise ultimately cool the planet.

According to the Chinese Centre for Disease Control and Prevention, the burning of coal is responsible for 70 percent of the emissions of soot that clouds out the sun in so much of China; 85 percent of sulfur dioxide, which causes acid rain and smog; and 67 percent of nitrogen oxide, a precursor to harmful ground level ozone.

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).

I'm not sure, therefore, what is the basis for your description of a «permanent cloud of aerosols», particularly as it relates to sulfur emissions.

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».

From sulfur aerosols to iron ocean seeding to artificial trees to cloud whitening, new earth - altering technologies are moving from science fiction to reality, challenging the capabilities of our international institutions in the process, and forcing us to re-examine the ideas that hold our political world together.

The cloud of ash and sulfur dioxide caused the Year Without Summer in 1816, a year so cold that crops failed around the world, causing massive famine.

The stabilistaion of Venus is caused by the surfur dioxide clouds which formed when the surface became hot enough to vaporise the sulfur.

Tinkering with the Earth and its atmosphere in an attempt to fend off global warming — a.k.a. geoengineering — seems like the stuff of science fiction: Lacing the stratosphere with sulfur aerosols or whitening clouds over the ocean to reflect sunlight back into space.
