|Home > Atmosphere > Interacting Problems|
As if each
of the major atmospheric problems were not enough by themselves, they
can interact and reinforce each other. Recent research has shown that
acid rain and global warming can greatly magnify the effects of ozone
layer thinning. In Canada, regional warming has reduced precipitation
and thus dissolved organic carbon inputs to lakes, while acidification
reduces the productivity of some plants. Together these can raise ultraviolet
penetration in lake water from thinning ozone by up to 800 percent, causing
increasing damage to lake ecosystems (Schindler,
et al., 1996).
