Back in the summer of 2008 athletes from all over the world were getting together in China for the 29th edition of the Olympic Games. Just prior to the games inaugural ceremonies there were a lot of concerns about the air quality, the contamination, and the heat in Beijing. Many athletes wore face masks to prevent getting sick prior to their respective competitions. We might be asking ourselves, what does that have to do with climate change? As China and its neighbors economies grow, the need for more energy increases. In order to meet their energy demands, industries have to use fossil fuels for energy. Fossil fuel burning accounts for 75% of the total global energy use (Ciserone, 2000, p. 1). When fossil fuels are burned, greenhouse …show more content…
Solar energy heats up the atmosphere and can affect the abundance of some greenhouse gases. Volcanic eruptions can create negative forcing by increasing the concentration of sulphate aerosols in the stratosphere. But these natural induced forcing have not changed the earth’s climate significantly. In the other hand, solar and volcanic events would likely have produced cooling instead of warming. Therefore, the radiative forcing from human activities is much more influential to current and future climate change than the estimated forcing from natural processes. Because of that anthropogenic influence the earth’s climate and life cycle is in constant change. Science shows that human influence extends beyond average temperature increase to other aspects of the climate. These influences have contributed to changes in wind patterns affecting tropical storm temperature and patterns, increased the risk of heat waves, contributed to sea level rise during the late 1900’s, increased the frequency of heavy precipitation events, and variations in winter and summer night and day temperatures. Due to these and other climatic changes the warming has been discovered to be greatest over land and at most high northern latitudes. The reduction of snow covered areas, and the decrease of sea ice extent is also a major indicator of climate change. Arctic late summer sea ice disappears almost in its entirety during warmer summer months creating a
