Climate Change Economics

Question: Discuss about theClimate Change Economics. Answer: 1. Humans are responsible for the change in the climate and the influence of the human on the climate system is clear. The influences of the humans are identified in warming of the atmosphere and the ocean. The humans are also responsible for bringing changes in the global water cycle as well as reduction in snow and ice. The activities of the human beings results in the release of the greenhouse gases such as carbon dioxide, methane and nitrous oxide (Archer 2016). The evidence is that the continuous emission of the greenhouse gas that led to the further warming and changes in all components of the climate system. 2. The observed changes are the warming of the climate system, which resulted in the increase in the sea level, and the warming up of the atmosphere. 3. The scientist expects that the concentration of the carbon dioxide in the atmosphere is likely to increase in the future. This will be mainly due to the high dependency of the human beings on fossil fuels. The scientists also expected a global average warming of around 4.5à ¢Ã¢â‚¬â€Ã¢â‚¬ ¹C by the year 2100 (Keenan et al. 2013). 4. The changes in the climate will intensely affect the human societies as well as the natural environment. The impact of the climate change in both Australia and other parts of the world are much clear. The climatic changes will result in the increase in the temperatures as well as the harshness of heat waves. These will on turn result in the changes in the growth and distribution of the plants and animals.
