climate change brings Inflation challengeAlso, inflation will increase as production is cut to be fall down, due to shortage of labor supply challenge brings any manufacturing product supply number is also decreased. Particularly real incomes and spending in the worse climate changing countries. Thus, inflation is likely to rise over time, driven by rising food prices and an increase in the cost of energy. Although, the climate of some countries is predicted to become more accommodative to agricultural yields in the medium term, but the long-run implications of rising temperature are likely to reduce global crop yields overall. Also, costs are also likely to increase through higher insurance changes. But premiums in climate risk areas are increased, feeding into higher costs for businesses and homeowners. From this perspective, the cost of climate changes are already affecting global activity.1.1Scientists' opinions of quantifying the impact on activitySome scientists gave opinions to indicate that how climate damage functions of quantifying the impact on activity. They showed to value the future loss in economic output attributable to climate change produces a range of estimates which vary according to views about whether a fipping point is reached between 2 to 4 degree warming. In a worst cause scenario, global warming could be seen to reduce annual GDP growth by over 1 % between the present day and 2080 year. They also predicted developing countries are set to absorb much of the losses caused by climate change. relying more heavily on climate sensitive sectors, such as agriculture and tourism and having naturally warmer climates, they will experience the most adverse effects an activity.Assessing the impact of climate change is at least, an extremely complex challenge with uncertainty about both the degree of future global warming and the subsequent impact on global activity. There are clearly some benefits as well as costs as the planet warms. There is also the unknown of how technological progree will respond and potentially alter the path of global warming. However, increasingly awareness of the issue means there is a growing demand for a view shareholders who are either concerned about how the companies they own impact the environment, worried aout the effect of climate change and people immigrate to better climate countries to work and live.1.2How Global warming influences economic growthHowever, global warming will primarily influence economic growth through damage to property, last productivity, mass migration and security threats. For New York, examples of the economic damage, such extreme weather events can cause such as: rising sea levels will also likely harm economic outputs as businesses become losses. Climate change is likely reduce the capital stock and productivity in the world economy. If we assume less capital stock is available, due to the damage inflicted from climate change. We would see a fall in the productive capacity of the world economy. This would translate into a downward shift in the world production function as each unit of labour produces less output. Lower labour productivity may not just occur, due to a lower level of capital stock. However, higher global temperatures may affect food security, promote the spread of infections diseases. Such those migration and global warming factors are likely to cause greater incapacity and social population uneven distribution and as a result will reduce both the affect( productivity) and the amount of labour available to produce output.
