Sentences with phrase «stratospheric ozone loss»

Although no stratospheric ozone loss had been observed yet, CFCs should be banned, they said.

To my narrow way of thinking, this of course * was * a huge (as poorly quantified as that is) stratospheric ozone loss â??

To my narrow way of thinking, this of course * was * a huge (as poorly quantified as that is) stratospheric ozone loss â??

Increased polar stratospheric ozone losses and delayed eventual recovery owing to increasing greenhouse - gas concentration.

Increased polar stratospheric ozone losses and delayed eventual recovery due to increasing greenhouse gas concentrations.

«Although stratospheric ozone losses are expected to stabilize and eventually recover to preindustrial levels over the course of the twenty - first century, these results show that increasing greenhouse gases will continue to intensify the polar vortex throughout the twenty - first century, but that radiative forcing will cause widespread temperature increases over the entire Southern Hemisphere.»

Shindell, D.T., D. Rind, and P. Lonergan, 1998: Increased polar stratospheric ozone losses and delayed eventual recovery owing to increasing greenhouse - gas concentrations.

Not exact matches

Through extensive modeling of stratospheric chemistry, the team found that calcite, a constituent of limestone, could counter ozone loss by neutralizing emissions - borne acids in the atmosphere, while also reflecting light and cooling the planet.

This ozone will help to compensate for any losses in stratospheric ozone, but at the cost of causing global warming.

In addition, the larger than expected loss of UV light meant less stratospheric ozone up to 45 kilometers above the surface, but more above that line.

How does this relate generally to stratospheric cooling over recent decades and the apparent positive feedback whereby ozone loss causes further cooling which leads to further ozone loss...

The study about the research was published in the Proceedings of the National Academy of Sciences under the title «Stratospheric solar geoengineering without ozone loss.»

There is a progression of global impacts from the loss of stratospheric ozone, to decling global fish stocks, to loss of topsoil and now global climate change.

An excellent example is the determination by Molina and Rowland (1974) that CFC's will lead to losses in stratospheric ozone.

Since its emergence in the 1980s, the Antarctic ozone hole, the near - complete loss of lower - stratospheric ozone, has occurred every year.

In the Antarctic, essentially complete removal of lower - stratospheric ozone currently results in an ozone hole every year, whereas in the Arctic, ozone loss is highly variable and has until now been much more limited.

In the year with strong wave energy, by contrast, the lower stratospheric warming in July and August leads to reduced ozone losses throughout the Southern Hemisphere spring, when the sunlight that powers ozone depletion chemistry returns to the polar regions.

States that several interlinked processes have been suggested as contributing to the warming, including stratospheric ozone depletion, local sea - ice loss, an increase in westerly winds, and changes in the strength and location of low — high - latitude atmospheric teleconnections

If this happens during northern winter, surface pressure falls in the Arctic (rising AO) the night jet stalls, NOx injection falls away, stratospheric ozone levels increase, the coupled circulation is invigorated and pressure falls at 50 - 60 ° north and this is associated with cloud loss (when global cloud cover is at its maximum value) and a strong rise in global sea surface temperature.

He says that rather than global warming we should be worrying about stratospheric cooling and the resultant loss of ozone which he categorises as disastrous.

Several interlinked processes have been suggested as contributing to the warming, including stratospheric ozone depletion, local sea - ice loss, an increase in westerly winds, and changes in the strength and location of low — high - latitude atmospheric teleconnections.

But not only must models of ozone loss and recovery factor in global warming — abnormally low stratospheric ozone has also a marked effect on climate change here and now.

The evolution of the forcing due to stratospheric O3 loss hinges on the rate of recovery of the ozone layer, with special regards to the spatial structure of such a recovery in the mid - to high latitudes.

The loss of stratospheric ozone could also significantly cool the stratosphere, potentially causing destructive climate change.

The ozone losses predicted in the study are much larger than losses estimated in previous «nuclear winter» and «ultraviolet spring» scenario calculations following nuclear conflicts -LSB-...] A 1985 National Research Council Report predicted a global nuclear exchange involving thousands of megatons of explosions, rather than the 1.5 megatons assumed in the PNAS study, would deplete only 17 percent of the Northern Hemisphere's stratospheric ozone, which would recover by half in three years.
