How carbon dioxide affects the ozone layer

At the poles, CFCs attach to ice particles in clouds. Qin, M. Eyring V et al 2010a Sensitivity of 21st century stratospheric ozone to greenhouse gas scenarios Geophys.

There is an additional factor that indirectly links ozone depletion to climate change; namely, many of the same gases that are causing ozone depletion are also contributing to climate change. The Southern Ocean is a region that is particularly sensitive to global warming.

In addition to this global motion, strong winter polar vortices are also important to concentrating ozone at the poles. At present, the amplitude and extent of such a cooling, and therefore the delay in the recovery of the ozone layer, still have to be assessed.

Ozone depletion

Anthropogenic ozone-depleting chlorocarbons and bromocarbons are declining due to cessation of their production as a result of the Montreal Protocol and its amendments Andersen and Sarma 2002.

It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere. Carbon dioxide concentrations are increasing in all layers but the exosphere.

Using original simulations, they have demonstrated that the hole in the ozone layer reduces atmospheric carbon uptake in the Southern Ocean and contributes to the increase in ocean acidity.

In particular, the O x and NO x cycles are strongly temperature dependent while the ClO x and HO x cycles are significantly less temperature dependent see e. September 14, 2010.

Impact of future nitrous oxide and carbon dioxide emissions on the stratospheric ozone layer

You can follow any responses to this entry through the RSS 2. Install Opera Mini to better experience this site. Ozone is found in two different parts of our atmosphere.

Ozone depletion occurs when chlorofluorocarbons CFCs and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere see details below.

Ozone Hole Reduces Atmospheric Carbon Dioxide Uptake In Southern Ocean

GSFC2D simulates an increase of around 0. Marquis, K.

Something was destroying the ozone in the upper atmosphere. Two layers that make up the middle atmosphere -- the stratosphere, where jets fly, and the mesosphere -- cover the troposphere. Are the ozone hole and global warming related?

This feedback between temperature and NO x concentrations affects the impact of increased N 2 O on stratospheric ozone. These include: Until now, the saturation of the carbon sink in the Southern Ocean has not been correctly simulated by the climate models used.

N 2 O increases lead to increased production of nitrogen oxides NO x , contributing to ozone depletion. The CH 4 boundary condition is also set at a fixed value 1.
