An Inconvenient Truth

when in college he attended a course taught by Roger Revelle.  Revelle is one of the first scientists to measure carbon dioxide concentrations in the atmosphere.  He conducted many experiments testing the earth’s carbon dioxide concentrations and then compared them to the earth’s temperature to see any similarities.  After a few years of research, Revelle realized an increase in carbon dioxide emissions.  Gore was amazed by the type of research and the amount of difference in the carbon dioxide from year to year.  This amazement led to the Gore’s interest in global warming and led to him presenting the following information in the movie.  In many experiments, Gore has understood that during the different weather seasons, the amount of carbon dioxide fluctuates because of the sunlight received. It has also been recorded that many glaciers are melting every year.  Also, many mountains are beginning to shrink in size because they are also melting slowly each year.  The carbon dioxide measurement can be measured since 1000 years ago and can be tracked that far back as well.  It has been said that he carbon dioxide levels were increased in the medieval era as well as the temperature, but the warming of the earth and the carbon dioxide levels go beyond those levels back in the medieval era.  The reason measuring carbon dioxide is vital to figuring global warming is because the more carbon dioxide in the atmosphere causes the temperatures to rise as well because the atmosphere is trapping the sunlight because of the pollution.  This pollution absorbs the light in order for the atmosphere to receive enough sunlight.  Gore showed some data graphs that depicted the earth’s temperature in 50 years.  The data described that the graphs have increased exponentially by two times as much in previous years.  With some calculation, in the next 50 years, the graph is supposed to increase exponentially by five times.  This is outrageous and needs to be controlled if civilizations desire to exist any longer on the earth.  It is no coincidence that the ten hottest temperatures in the history of the world have occurred in the past 14 years thus illuminating the effect of global warming in the past decade.  This hot weather climate has caused many deaths, mainly in Europe in 2003, and also affects the weather patterns when they occur.  The warm weather has caused the land to be dry thus making it harder for farmers to grow their crops.  It has also led to many hurricanes and typhoons in East Asia and also in the United States, for example Hurricane Katrina in New Orleans.  One of the wisest men to live on this planet stated that we would suffer our deepest consequences for our actions.  This was stated by Winston Churchill who was implying that the ways the people were treating the earth with so much pollution, that we would one day indeed suffer for our actions.  At the time many did not listen to his comments, and the few that did were not in accordance with this beliefs.  Due to the earth’s vast warming rates, the amount of precipitation has increased and has also relocated.  This has led to dry land and has also led to the need of precipitation which has occurred in many places, but has precipitated more than needed thus leading to flooding.  Another effect of global warming is that evaporation occurs more because of the excessive sunlight received into the atmosphere.  Due to this evaporation the land becomes dry for example many parts of Africa.  Another tell-tale sign of global warming is the melting of the arctic ice.  The arctic ice is the first part that receives sunlight, thus the arctic ice has been drastically melting in the last decade.  All these signs have led Al Gore and many scientists to believe that global warming is occurring.   The future does not look any better since the humans are reproducing more often than the past “baby-boomers”.  The baby boomer generation was with 2 billion people, and in less than 100 years later, the population has already reached a little under 7 billion people.  We must work hard to control global warming so that your earth stays safe and we stay alive.
