Physicists have discovered that alteration of our planet’s ozone layer related to climate change will increase the amount of ultraviolet (UV) radiation from the sun in tropical areas and even Antarctica. The opposite effect on UV radiation will be felt in northern areas such as northern Canada, Scandinavia and Siberia.
Researchers at the University of Toronto set out to explore how climate change will affect the Earth in terms of regions, according to Science Daily. Based on advanced computer modeling, lead author Michaela Hegglin, a postdoctoral fellow in the Department of Physics, and physicist Theodore Shepherd found that changes in UV radiation will result from the alteration of atmospheric circulation due to climate change. The change in circulation will lead to movement of ozone from the upper to the lower atmosphere, thereby altering the distribution of ozone in the upper atmosphere.
The study was funded by the Canadian Foundation for Climate and Atmospheric Sciences as part of a collaborative project with several Canadian universities and was published in Nature Geoscience journal.
