The effects of climate change and global warming are of utmost concern for both the human life and the environment. Evidences of observed climate change include the rising of sea levels, decreased snow cover within the Northern Hemisphere and the instrumental temperature record. According to the 4th Assessment Report of the IPCC, most of the observed increase within the global temperatures since the 20th century maybe due to the observed in greenhouse gas concentrations. It has been predicted that future climate change will also include additional global warming.
Precipitation is the deposit on the earth of mist, hail, rain, snow or sleet. It is also the quantity of water that is deposited on the earth. On the other hand, atmospheric moisture is considered as the water in gaseous or liquid form that is present in the atmosphere. Precipitation and atmospheric moisture are important in the earth’s water cycle. These two are now of main concern due to climate change.
There must be a high increase in precipitation so as to balance the evaporation of the earth today due to global warming and climate change but the process by which the precipitation can be altered locally are still not understood. Precipitation, which includes extra tropical cyclones, thunderstorms, rain clouds and hurricanes mostly, feed on the moisture that is already present in the atmosphere. This means that the atmospheric moisture of our planet directly affects the snowfall and rainfall rates. The more moisture in the atmosphere, the more storms and extreme weather events will happen over the years.
It has been argued that the result of further global warming leads to the increase in the atmosphere’s moisture content, which favors stronger weather events such as storms and cyclones. This means that when it rains, it would rain harder than it used to be under similar circumstances.
