... the world population lives within sixty kilometres of a coastline(Ehrlich and Ehrlich, 1970, p.125). This obviously leaves the oceans and lakes vulnerable to a great deal of pollution(see Map 1). The run-off of water tainted with phosphates from fertilizers is a major contributor. In many underdeveloped counties (and to a lesser extent, developed countries) unprocessed sewage and industrial waste is pumped or ... 203). As population and industry grow, so does the need for increased agricultural production. This results in a heavier water-borne load of pesticides, herbicides and nitrates. ...

... increase the number of very hot days that occur during the year. More hot days increases the possibility of heat related health problems. Indirectly, ecological disturbances, air pollution, changes in food and water supplies, and coastal flooding are all examples of possible impacts that might affect human health. How people and nature adapt to climate change will determine how seriously it ... largely 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 w...

... The gases then radiate energy back, which causes the temperature to rise, this slight raising of the temperature, then causes greater evaporation. Since water vapor is the principal greenhouse gas, this causes the temperature to rise even more, thus more evaporation. This positive feedback would melt glaciers and ... in the computer models and in our past assumptions that the atmosphere is so well behaved. These models just don't handle processes like clouds, water vapor, and precipitation systems well enough to accurately predict how strong global warming will be, or how it will manifest...
