Picture in your mind a world in which the temperature is at least ten degrees higher than it is today, where they’re supposed to be snow you can see a green valley and all the major cities are covered by water. This imaginary picture is not too far from the truth. This essay will discuss the effects of global warming as a life threatening condition causing extreme heat waves, glacier retreat and sea level rises.

The first effect of global warming is the dramatic increase of temperature all over the globe. The actual readings show a global warming of around 0.6 degrees Celsius over the entire 20th century. Furthermore, any micro change in the temperature can generate severe weather conditions like rain and tornados also, some areas may experiment extreme heat waves that could derivate in death by dehydratation. Other contributors for the changes in temperature are the greenhouse gases. Greenhouse gases are naturally generated by solid waste in the form of methane gas. The human generated ones that comes from automobile exhausts and heaters from homes including factories wastes. Although, greenhouse gases are mainly natural the real problem resides in the excess of this gases overheating the planet.

With the change in temperature previously indicated, there is a second effect of global warming, glacier retreat. Places traditionally known by snow or cold weathers now report less amounts of snow and a rise in temperature for example, in the Chimborazo volcano, Ecuador, the snow of the glacier is retreating at a rate of 0.5 meters each year also Antarctica reported to have the warmest year in all history. Remember that most of the water for human consumption comes from the glaciers, when they melt over controlled conditions the water resulted from the melting goes to rivers. Moreover, if the melting continues and the glacier disappears there is a good chance that there will be no more water to drink.
