global warming1
Greenhouse gases (chlorofluorocarbons, carbon dioxide, methane, nitrous oxide, etc.)let heat in but stop it from going back out - like a windshield in a parked car. At our current rate of creating these gases by industry, cars and burning fossil fuels, scientists predict a temperature increase of 4 to 9 degrees F by 2050. (9 degrees F separates today's average temperatures from the last ice age.) The United Nations Panel on Climate Change recommends that we immediately cut our use of fossil fuels by at least half. To prevent the current rate from increasing, we would have to cut by 60%. This same panel projects that by 2050 over a million more people dying each year from malaria because of higher mosquito populations due to global warming. Already yellow and dengue fever bearing mosquitoes are found over 3000' higher than their normal range in South America. Other predicted results of global warming include expanding deserts, forest fires, heat waves, crop failure, erosion, mud slides, mass extinction of plants and animals, sea level increases causing flooding and damage to coastal aquifers. The US with c. 5% of the world's population creates 25% of the 7 billion tons of carbon dioxide that causes 50% of the global war
It is said, "if the carbon dioxide increases, the Earth becomes hot." By what mechanism does this happen? Looking at the data from 1880 to 1994, we can see that it is increasing by the rate of 0.6°C/100yr in a long range. However we have to examine quantitatively whether this increasing tendency is due to the increase of the green house effect gases or it is part of a variability on some longer time scale. If these green house effect gases continue increasing, the amount of absorption of the infra-red lays increases and the atmospheric temperature may rise correspondingly. This is why the problem of the global warming is raised. · Immigration of residents near the sea coast and on the small islands. Trend of the green house effect gases · Effects on agriculture, stock raising, and forestry.
