Sentences with phrase «polar ozone hole»

Observations of the polar ozone hole were not predicted.

Ozone recovery in the tropical stratosphere is expected to be faster and the recovery of the polar ozone hole is expected to be slower because of the CO2 - induced cooling of the stratosphere (and increase the number of polar stratospheric clouds).

Subsequent work indicated that the polar ozone hole (starting in the early 80s) was having an effect on polar winds and temperature patterns (Thompson and Solomon, 2002; Shindell and Schmidt, 2004), showing clearly that regional climate changes can sometimes be decoupled from the global picture.

«On Earth, ozone destruction by refrigerator CFCs is the cause of the polar ozone hole.

«We believe this could be the major mechanism for the creation of the polar ozone hole,» Lu says.

Not exact matches

«There are ways that this approach could increase global ozone but at the same time, because of the climate dynamics in the polar regions, increase the ozone hole.»

Hence the presence of an ozone hole in the very cold Antarctic polar vortex.

There are ways that this approach could increase global ozone but at the same time, because of the climate dynamics in the polar regions, increase the ozone hole,» Keith said.

The recipe for massive springtime ozone loss in the polar regions, such as the annual ozone hole seen over Antarctica during the past two decades, is fairly simple.

There is nothing «natural» about these extremes of weather over the last 2 years, or about the unprecedented ozone hole in the Arctic last year (troposphere warming from greenhouse gases caused stratospheric cooling to below threshold temperature for polar stratospheric cloud generation and ozone destruction).

An example of this kind of surprise happened in relation to the Antarctic ozone hole, where unexpected chemistry on surfaces of ice particles lead to much more efficient destruction of ozone in the polar vortex than had been expected, making an existing concern into a serious problem.

I think that this was after 1987 when doubt concerning the causes of the Antarctic Ozone Hole were certainly politically motivated because 1 ppb of ClO measured in the polar vortex made scientific doubt insane.

Ozone holes are caused by chemical reactions that take place primarily on the surface of polar stratospheric clouds, ice particles, or liquid droplets, which form at high altitudes in the extreme cold of the polar regions.

If the record had been a tropical jungle or sea I'd have considered my hypothesis falsfied but so far every prediction made by it fits what has been observed with the sole exception of the Antarctic interior but that may be due to exceptional characteristics such as the strong polar vortex, ozone hole, and a temperature far lower than anywhere else on the planet.

There is a limit to breadth and width of society - wide derangement, corruption, superstition and ignorance until the baseless fearmongering, inhumanity and social pathology finally brings the Tower of Babel down around our ears: Bush derangement syndrome, Palin derangement, McCain derangment, Romney derangement Ryan derangment, Tea Party derangment, skepticism derangement, Hot World derangement, capitalism derangement, Judeo / Christian derangement, disastrous climate change derangement, CO2 is a pollutant derangement, its Ozone Hole derangement, Melting Glaciers derangement, its Seas Will Swallow us derangement, Man is causing earthquakes derangement, Death of polar bears derangement, GlacierGate, AmazonGate, PachauriGate, UN-IPCCGate, ChinaGate, CRUGate, HimalyaGate, SeaLevelGate, RainForestGate, HurricaneGate, GreenpeaceGate, SternGate, KiwiGate, HockeyStickGate, WeatherStationGate, HansenGate, NASAGate, GISSGate and NOAAGate, NobelGate...

The discovery of the so - called «ozone hole» over the south polar region in 1986 was so disturbing, in fact, that 197 nations agreed to ban CFC's, widely used in air conditioners and refrigerators, just a year later, in an agreement known as the Montreal Protocol.

Although the satellites are considered the gold - standard for measuring and observing sea levels, hurricanes / typhoons, ozone holes, sea ice, atmospheric CO2 distribution, polar ice sheet masses and etc., the same 24/7 technology used to measure temperatures across the entire habitable world is now being ignored (i.e., denied) due to the above inconvenient evidence.

Closing the ozone hole actually speeds up the melting of the polar ice caps, according to a 2009 study from Scientific Committee on Antarctic Research.

If you believe government scientists saved the world from DDT, overpopulation, acid rain, the ozone hole — just as they have rescued polar bears from the brink of extinction and stopped the seas from rising — then, I have a photograph you might want to buy of George Bush and Big Foot playing hockey.

The southward shift in the tropospheric jet extends to the surface of the Earth and is linked dynamically to the ozone hole induced strengthening of the Southern Hemisphere stratospheric polar vortex.

The Polar bears stubbornly refuse to go extinct, indeed the buggers are thriving, the glaciers don't appear to be disappearing, sea levels have stayed boringly level, we haven't been subsumed by hordes of desperate climate refugees, the polar ice caps haven't melted, the Great Barrier Reef is still with us, we haven't fought any resource wars, oil hasn't run out, the seas insist on not getting acidic, the rainforest is still around, islands have not sunk under the sea, the ozone holes haven't got bigger, the world hasn't entered a new ice age, acid rain appears to have fallen somewhere that can't quite be located, the Gulf Stream hasn't stopped, extreme weather events have been embarrassingly sparse in recent years and guess what?

Richard, as I pointed out elsewhere in this thread, the ozone hole facilitates cooling in the southern polar region while the circumpolar vortex block warm air advection from the north.

The CFC ozone hole only occurs in the polar spring, after the dark night is over.

Stratospheric ozone science: To elucidate the geographical extent of, and mechanisms responsible for, ozone depletion in the «ozone hole» region and to study dilution effects and possible heterogeneous chemistry even outside of the polar regions due to sulphate aerosols.

A good example is the consensus of chemistry models that projected a slow decline in stratospheric ozone levels in the 1980s, but did not predict the emergence of the Antarctic ozone hole because they all lacked the equations that describe the chemistry that occurs on the surface of ice crystals in cold polar vortex conditions — an «unknown unknown» of the time.
