Global Warming Facts
The global warming facts are evident and undeniable. Let's just mention some of the global warming facts: half of the world's wetlands were lost last century; soil degradation has affected two-thirds of the world's agricultural lands in the last 50 years; 400,000 square miles of Arctic sea ice have melted. One of the most serious global warming facts is the rise of the mean sea level. Satellites are used to measure the change in average global sea level over time. Their figures show that the change in sea level is accelerating, which is expected as a result of global warming.
Another very important global warming fact is that we humans are solely responsible for global warming. We are causing it! Why? Because we are more than 6 billion and the number is increasing all the time. We are breathing out CO2, 90% of our cars are absolutely fuel inefficient and are filling the atmosphere with CO2, in fact our buildings are the number one CO2 producer. World population would not be a problem if there were unlimited land, unlimited water, and unlimited resources. Unfortunately, with overpopulation, there is the problem of sharing the same sized pie with smaller and smaller portions. People in developed countries who have been accustomed to a better quality of life are reluctant to give it up. In many cases, more efficient use of resources has come along hand-in-hand with improved quality of life. But there are still problems of over consumption, exploitation, the short-sighted search for an ever-higher quality of life, and the greed of companies and individuals in cutting corners resulting in pollution and reckless use of raw materials. In the past, agriculture had less impact, cities had fewer vehicles to send pollution into the air, and industries were not as attracted by cheap labor and thus polluted rivers and the air less. We need to balance the quality of life between the rich and the poor, at the same time, hoping to balance the family size between the rich and the poor. Computer simulated models are made to predict what the situation will be after 50 years and the picture doesn't look bright. The average global surface temperature is projected to increase by something between 1.4 and 5.8°C (2.5 to 10°F) over the period 1990 to 2100. Some extreme events are expected to increase in severity. Northern Hemisphere snow cover and sea-ice extent are projected to decrease further, as well as glaciers and ice caps. |
