Removing ozone from lower stratosphere (i.e. ozone hole) cools cold air further over Antarctica. Also ozone decrease, and carbon dioxide increase both contribute to increase in southern westerlies, which support ACC (Antarctica circumpolar current). Increase in westerlies pushes surface cold water away from Antarctica, and allows upwelling of salty warm water. Do we fully understand what effect ozone (increase or decrease) might have on Antarctica weather? Should we go slow in any intervention?
