Global Warming Effects
What is Global Warming
Global warming is a marked and extended change in the Earth’s climate for the warmer
Climate change is an extended change in the Earth’s regular pattern of atmospheric conditions and its fluctuations
Global warming is caused by an enhanced greenhouse effect caused by human activity more
The greenhouse effect is caused by the trapping of heat in the Earth’s
First the Sun’s high frequency rays of radiation enter into the Earth’s atmosphere in the form of visible light
Next the Earth absorbs these rays and radiates them back into the atmosphere as infrared radiation, or heat
Since the Earth’s atmosphere includes certain gases which even in small amounts can absorb infrared radiation, gases such as methane, carbon dioxide, fluorocarbons, and nitrous oxide, the infrared radiation is trapped by these gases and can not escape the Earth’s atmosphere
Lastly, as the Earth’s atmosphere traps more and more heat the Earth’s atmosphere begins to increase the temperature of the Earth itself
Global warming and Human Health
- Global warming will affect human health in a number of different ways
- The spread of infectious diseases will be affected
- Agriculture will be affected
- Extreme weather patterns will be affected
