Economic science helps to understand economic benefits and material losses caused by severe weather conditions taking into account results obtained by Climate science and Geology. Economic science investigates and develops measures to reduce negative impact of economic activity on climate and global warming. Taking into account the information mentioned above, it si evident that an interdisciplinary research is crucial, because one science is unable to solve the problem of global warming without collaboration with other disciplines.
Recent years, hurricanes have become a great problem for many coastal villages and towns around the world. Scientists explain that hurricanes are caused by heated water and variations of sea level. For instance, according to Avery: " The computerized global climate models predict we'll get more and bigger storms as the planet warms", which results in severe weather conditions. Avery explains that "heat in the atmosphere is the fuel that leads to stormy weather," and "weather disasters are occurring with ever-greater intensity and frequency around the world." (Avery, n.d.). So, it is evident that this "fuel" in the atmosphere is the result of human activities (gas emissions and other pollutant) which lead to the heated atmosphere and hurricanes.
Nevertheless, there is an opposite view supposing that "the present hurricane surge is part of a 60 to 70-year cycle linked to natural effects" (Briggs, 2005), and has nothing to do with heated weather conditions. Unfortunately, nobody can reject the fact that thousands of tons of mercury, lead, and other heavy metals are put into the water and air each year in the form of liquids and gases, which cause the sea temperature increase. Heavy metals, like pesticides, are long lasting and can spread over large areas. Algae and fish are disappeared and natural processes of adsorption stops. These changes in biosphere resulted in global warming.
b) Tornados is another problem caused by heated water. This phenomenon was proved by Carter who stated that tornados are caused by temperature increase and storm chasing. He illustrates this fact stating that 'the escalation in extreme weather conditions over the past two decades has led to an increase in the frequency and intensity of storm conditions" (Carter, 2005). Some scientists try to explain tornados and storms as a result of changing weather conditions neglecting the influence of global warming on this process. They say: "When we look at the Mozambique floods, at the storms that hit France, at the absence of winters in Britain over the past few years, at the avalanches in the Alps, we are witnessing events that are now clearly tainted by human actions" (Carter, 2005). The question is "Why changing weather conditions occur" Following Carter, it is possible to say that these changes occur because of global warming.
To conclude, it is possible to say that the majority of scientists agree that global warming and "green house effect" are the main reasons why we suffer from
