Global Warming

Global warming has become a major issue that no one should take lightly.   It leads to many difficulties that deeply hurt our Planet.   It causes many natural disasters such as tropical cyclones, heat waves and not to mention significantly less cold weather, all which affect our ecosystem (Tibbetts 2007).   These horrible alterations in our ecosystem also result in many different diseases that affect our human species.   The author of this article, John Tibbetts, focuses four different main points in this article.   One is what happens when the climate is hot and dry.   Another point is when the climate is wet and dry.   Human roles and different diseases that affect humans is a third point that is talked about.   Finally, in this article expert scientists give some suggestions that involve us acting in order to reduce the way we humans take nature and our natural resources for granted.
Tibbetts talks about situations that have occurred in hot, dry weather.   He starts by saying that the climate change results in a lot more heat stroke victims.   As most know, those susceptible to reacting to the unbearable heat are elder people, the poor and those that have pre-existing diseases especially respiratory and cardiovascular diseases.   Tibbetts also talks about the affect the heat has on the ozone layer.   This ground-level ozone occurs because of reactions from vehicle fume emissions.   When these gases interact they can cause death by heart and lung ailments (Tibbetts 2007).   These extremely hot and dry climates can also cause more allergen exposures.   Carbon Dioxide mixes with warm climates and stimulates the growth of plants like ragweed.   Another major point Tibbetts makes is that dry weather can cause droughts in places that were never water-stressed before.
Tibbetts also talks about hot and wet climates.   He starts off by talking about the warm weather making the temperature of the surface water of the ocean go up and eventually this water will expand, a process known...
