Effects of Human Activities on Climate Change
Our large appetite for oil and coal and deforestation during the last 200 years has increased the average temperature of the earth atmosphere. The rise in fossil fuel consumption has deposited large amount of carbon dioxide in the atmosphere which blocks the escape of infrared radiation into space. Infrared radiation is heat emitted from the earth’s surface. This greenhouse gas raises the earth’s temperature significantly. According to NOAA (National Oceanic and Atmospheric Administration) and NASA, at the end of this century, the earth’s average temperature will have risen to 3.2 to 7.2 degrees Fahrenheit. This is significant because during the last ice age where snow and glaciers covered most of North America, the temperature is only 7 degrees Fahrenheit below than the average temperature today. The greenhouse effect of this global warming affects people’s health; most affected are people in poor countries with poor healthcare especially during periods of prolonged heat waves, and possibly during outbreaks of malaria which proliferate in warm weather climates. World Health Organization or WHO reports that “extremes of heat and cold can cause potentially fatal illnesses, e.g. heat stress or hypothermia, as well as increasing death rates from heart and respiratory diseases.” It thins ice caps, melts glaciers, and raises water sea level. Because the amount of precipitation & evaporation changes, the middle of North America might suddenly experience less precipitation than normal; thus, crops in that region may not be able to adapt to the rapidly changing climate which could have a devastating effect on the economy, and disrupt world food supply. Scientists believe that we are at a point of no return, and the changes are inevitable. It is already happening. Spokesman for Global Warming Al Gore is unquestionably correct.
