The average surface air temperature has increased by about 0.6 degrees Celsius in the last century. Interestingly, this occurred in three phases: a relatively rapid rise of 0.4 degrees between about 1910 and 1940, a surprising plateau between 1940 and 1975, and another rise of about 0.2 degrees Celsius between 1975 and the 1990’s. Nine of the eleven hottest years in the twentieth century have occurred in the last ten years. In addition, studies done on tree rings, corals, ice cores, and historical data prove that the 1990’s are the warmest decade in at least the last 1000 years. The Intergovernmental Panel on Climate Change foresees an increase of one degree Celsius to 3.5 degrees Celsius in the global mean temperature by the year 2100. They have also forecasted a ri

In conclusion, global warming is an issue that we can no longer put off and we must face today. If nothing is done then we are only causing doom down the line. The environment is in danger and we need to help it.

Global warming will cause vermin to spread to new suitable habitats, thus bringing diseases to afflict newly vulnerable human populations. An example is the Mosquitoborne malaria. The mosquito is mostly restricted to humid regions with an average temperature above 61 degrees and about forty percent of the world. Global warming in the range of six to ten degrees would increase malaria carrying mosquitoes to sixty percent of the world.

Talks about an international agreement aimed at reducing the carbon dioxide emissions of industrial nations to pre-1990 levels by the year 2012, failed in the last month of Bill Clinton’s presidency. The Bush administration has already announced that it was not going to regulate the carbon dioxide emissions of power plants. This upset many environmentalists and angered European leaders. The program never left the ground and from the looks of it, it never is.

Not only do temperature readings show that the temperature is rising but also environmental signals have occurred. The migration of plants to higher altitudes has been documented on n
