Question

Potential global warming problems/impacts on humans, animals, the enviroment, commerce, and the economy?

Answer 1

Global warming is a natural phenomenon but the problem presently is human impact in rise in temperature which has increased the rate of rise in temperature and so something which would have happened 500 or 1000 years from now naturally will happen 50 years from now.

In natural way all those animals who are able to adopt to changes change their living style and remain safe and alive. Here, due to humna impact the rise is very high and many living creatures will become extinct since they will not ba able to adopt the changes. So our biodiversity topples.

Environment changes due different climatic changes and so it may start raining in Sahara desert and stop at other places. So the whole pattern changes.

When sea level rise a lot of land will be lost to it but we will also get new land in northern region around polar area. But, to adopt to these changes will take time and poor will not be able to do so and they will be problem. Farmers will be facing problem due to climatic changes and they will have to change sowing pattern. Grain production will go down at many places so chances of femine.

So, the whole economy and trade can suffer due to change in agricultural pattern.

But, the biggest loosers are going to be those creatures who will not be able to adopt to changes fast and poor countries and people.

Answer 2

Global warming is not going to have a major impact on any of these groups or things.  The oceans are only expected to rise around 2 feet.  If your home is closer to the ocean than two feet you might want to move but beyond that there will not be any major effects on the environment.

Answer 3

Coastal flooding and damage to agriculture.  Rich nations cope, with considerable damage to their economy because it takes huge sums of money.  In poor countries many people die of starvation.
