Not just about sunburn - the ozone hole's profound effect on climate has significant implications for Southern Hemisphere ecosystems
Climate scientists have concluded that stratospheric ozone depletion has been a major driver of Southern Hemisphere climate processes since about 1980. The implications of these observed and modelled changes in climate are likely to be far more pervasive for both terrestrial and marine ecosystems th...
