Global warming is a very dangerous problem in our world today. Responsible, and potentially responsible, for new diseases, health problems, and land loss, this problem deserves more attention than it is currently receiving.
             Presently, scientists believe that human activities are responsible for most of the warming over the last 50 years, and the steep acceleration of warming throughout the past 20 years. Our actions have permanently altered the chemical arrangement of our atmosphere for the worst. By increasing greenhouse gases, mainly carbon dioxide, methane, and nitrous oxide, we have helped to trap heat in the atmosphere, and raise the average temperature of the earth by 1?F in the last century. Higher temperatures on earth present many dangers to humans.
             Heat waves are the most obvious effect of Global Warming. Rising heat temperatures create hot spots or "heat islands" (Journey To Planet Earth), mostly in large urban areas. Heat waves are very dangerous, and potentially lethal to humans, especially those without air conditioning,
             Another danger that could result from global warming is the rapid spread and growth of diseases. Most bacteria that create deadly diseases thrive in warm weather. Malaria, Dengue Fever, Yellow Fever, and West Nile Virus, are among some diseases that would flourish in hotter weather. (Journey to Planet Earth). With earth being warmer, these infections could travel quicker, and more efficiently, being transmitted to more and more people.
             Climate change also promotes the growth of molds. This is because most fungi and molds commonly live in places with heat and humidity. Molds cause many problems for humans, such as respiratory problems, rashes, and other illnesses.
             Many natural disasters would also result from climate change. Tornadoes, Hurricanes, Floods, Typhoons, and Droughts are just some natural disasters that would be more common in a world with Global Warming.
