What are the effects of global warming? The effects of global warming occur across a very broad scope. First, the beautiful and magnificent icebergs and glaciers of the Arctic and Alaska will begin to melt and dissolve into the sea. This indirectly increases the average water level on earth and thus causes severe floods and natural disasters. Take for example; Hurricane Katrina that destroyed many homes and took away many lives in New Orleans is caused by the melting of glaciers and the imbalance of sea levels on the planet. (Mathias 2007). Apart from this, global warming also causes degradation of the ozone layer due to extreme heat and dangerous gases produced by factories, cars and chemicals. Several diseases such as malaria can be caused by global warming. This is because the increase in temperature favors the reproduction of different types of mosquitoes. (DeGaborik 2007). In addition to this, global warming can cause heatstroke and heat exhaustion in patients with cardiovascular problems. High temperature also causes the concentration of ozone to lower the atmosphere which carries many harmful pollutants that can cause respiratory diseases such as
