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
While the green house effect gases are actually increasing, is the atmospheric temperature around the land surface increasing in accordance with this?The atmospheric temperature is affected complicatedly by various factors such as the ocean or the Earth surface. · Destruction of the port facilities. Thus, the annual mean temperature of the whole atmosphere fluctuates in various time scales which range from a few years to more than several decades. Looking at the data from 1880 to 1994, we can see that it is increasing by the rate of 0. · Zonal climate belts shift several hundred kilometers to the pole. (*) The stratospheric ozone around the 20km height has the function of absorbing the ultra-violet rays. There had never been one even as high as $1 billion before 1988. 1995 was globally the hottest year in over 100 years and the driest in the UK for over 300 years. By these, it is considered that the natural environments are affected as follows: · Forests degenerate (especially in the semi-dry area). Trend of the atmospheric temperature around the Earth surface. It is known that the concentration of the carbon dioxide has fluctuated for the past one hundred-thousand years, especially during the ice age etc. · Effects on using water (increase of flood and shortage of water).
