Sentences with phrase «increased ozone loss»

Some climate models suggest that increasing greenhouse gases may be leading to a gradual strengthening of the Arctic vortex and hence increasing ozone losses, while others do not.

Some climate models suggest that increasing greenhouse gases may be leading to a gradual strengthening of the Arctic vortex and hence increasing ozone losses, while others do not.

Not exact matches

He also cautions that the 2005 numbers are still preliminary, however there is a clear trend towards increasing potential for Arctic ozone loss, which is realised or not depending on the vagaries of each individual winter.

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

Hence, the chemical loss has been balanced by transport, such that in spring 1999/2000 the ozone layer above the Arctic has still been as thin as it always is in fall, in contrast to the normal seasonal increase of the thickness of the ozone layer during winter.

He also cautions that the 2005 numbers are still preliminary, however there is a clear trend towards increasing potential for Arctic ozone loss, which is realised or not depending on the vagaries of each individual winter.

Increasing greenhouse gases may therefore be at least partly responsible for the very large Arctic ozone losses in recent winters, and the situation may worsen in the future.

The combination of these two cooling effects causes dramatically increased ozone depletion so that ozone loss in the Arctic by the year 2020 is roughly double what it would be without greenhouse gas increases.

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

Unions for Jobs and the Environment (UJAE), an organization of 12 national and international labor unions, including the United Mine Workers, the Teamsters and the Sheet Metal Workers, thinks the ozone revision «would lead to significant job losses across the country during a period of high unemployment, due to the significant increase in the number of counties classified as nonattainment.»

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.

Ozone loss in the stratosphere and the consequent increase in penetration of UV into the upper troposphere tends to reduce the differential between the atmospheric pressure in the stationary high pressure cell East of Chile and the low over Indonesia tending to move the atmosphere towards a constant El Nino orientation.

«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.»

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.

UV dosage levels in summer: increased risk of ozone loss from convectively injected water vapor

Models suggest that both the loss of ozone (the ozone hole that occurs in September / October every year) and increases in greenhouse gases lead to an increase in frequency of this climate pattern.

They warned that the loss of ozone would significantly increase the amount of skin - damaging ultraviolet UV - B light reaching the surface, greatly increasing skin cancer and cataracts.

Increased water vapor in the stratosphere makes it warmer on the ground by trapping heat, while the ozone loss makes it colder on the ground.

They calculated that if CFC production continued to increase at the going rate of 10 % / year until 1990, then remain steady, CFCs would cause a global 5 to 7 percent ozone loss by 1995 and 30 - 50 % loss by 2050.

At some sites about half of this increase can be attributed to ozone loss.

These models may well be significantly affected by increases in marine boundary layer ozone loss, but since they have only just started to be used to simulate 20th and early 21st Century changes, it is very unclear what difference it will make at the large scale.

Lu's predictions for increased polar ozone loss in 2008/2009 as a function of the low solar activity (and therefore higher CR flux) did not come to pass.
