... changes. For example, satellite estimates suggest that the difference in summertime erythemal UV irradiances between northern and southern hemispheres is around 10–15%. However, ground level measurements indicate that this difference may be even higher, probably due to lesser atmospheric pollution in the southern hemisphere. It is clear that under cloud-free skies there is a strong correlation between ... ground level erythemal UV radiation and levels of atmospheric ozone. Yet the effects of clouds, increasing troposphere ozone and aerosol pollution of the lower atmosphere modify this...

... and southern hemispheres, and over the oceans. Confirmation of 20th-century global warming is further substantiated by melting glaciers, decreased snow cover in the northern hemisphere and even warming below ground. In the United States, approximately 6.6 tons (almost 15,000 pounds) of greenhouse gases are emitted per person every year. Most of these emissions, about 82%, are from burning ... on local climate. Extreme temperatures can directly cause the loss of life. Moreover, several serious diseases only appear in warm areas. Finally, warm temperatures can increase air and water poll...

... create problems logistically when trying to meet needs of everyone. In urban areas, pollution and environmental contamination are more common than that if their rural counterparts. This pollution caused by populated cities could then inadvertently affect rural areas due to contamination of ground soil and the air we all breathe. Contaminated ground soil could easily alter rural people's sustained farming lifestyle in a detrimental way ... ...

... . Of the total world's freshwater supply, about one third is found underground, and when many rivers have been dammed, creating very dry land, the water cycle is disrupted causing the ground to become increasingly dry. As the world uses up its water resources, countries that lack water have asked Canada to assure them that if there were a water shortage in their ... determine the costs and benefits of allowing bulk-water exports. "There is a need for this work to help governments make decisions on issues such as water exports, or access to ground-water resources," it says. Canada is tyin...
