Business integration topics 1 - Essay Example The International Panel on Climate Change (IPCC) has come out with a report in 2007 which has tried to provide evidence for this phenomenon. According to this report, the average temperature on Earth in 1905 was 14Â ºC and since then has increased at a rapid rate of 2.5 annually. The warming period in the last 50 years has been double of that of the last 100 years. (Norcia 2008) There have been critics of these findings who suggest that such numbers are not abnormal, some critics or global warming skeptics have even said that the IPCC report is not based on science but instead it is based on some ‘new faith based religion.’ (Norcia 2008) There are three main greenhouse gases in the atmosphere; carbon dioxide, nitrus oxide and methane. The levels of all three gases has been increasing rapidly. Specifically, carbon dioxide has increased by 35 per cent, nitrus oxide has increased by 18 er cent from 1750 to 2005 and methane has increased 142.2 per cent from 1750 to 1990 and then 2.4 per cent in 2005. These rates are more than those shown in the ice cores and other geological data. (Norcia 2008) We can notice the change in the temperatures over the last couple of years, it has gotten fairly hot. The climate swings can be in both directions, warm and cold, but mostly there has been an increase in the temperature. There have been a few cold seasons as well but these remain insignificant in front of the high temperatures that the world all around has been expereincing. According to the findings of the IPCC report it is not the natural causes which have led to higher temperatures, it is rather human activities which have led to the phenomenon of global warming. Humans have increased their use of fossil fuel, deforestation and use of excessive fertislizers which has led us to theis problem. Many of the effects of global warming are being felt
