The Global warming effects of climate change may be physical,ecological,social,or economic. There does exist evidence of observed climate change that includes the instrumental temperature record. This would also include rising sea levels. There is also a decreasing snow cover in the Northern Hemisphere. According to the Intergovernmental Panel on Climate Change most of the global average temperatures since the middle of the 20 century is almost certainly because of the observed increase in human greenhouse gas. Future climate changes is predicted to incorporate further global warming and an increase in the sea level. It may include a more frequency of extreme weather events. The United Nations Framework Convention on Climate Change signatories have agreed to implement some policies so as to reduce emissions on their greenhouse gases.
The instrumental temperature record has shown a trend in climate of increased global mean temperature over the past hundred years.This also means a increase in Global warming effects. There are other observed changes of arctic shrinkage, arctic methane release in coastal sediments, and sea level rise. The arctic methane which releases terrestrial carbon from permafrost regions has also been observed.Over this century it is predicted that the global average temperature will rise. That will have a possible increase in the frequency of extreme weather events and changes in rainfall patterns. The probability of this warming having any consequences will increase with the rate,magnitude, and duration of the climate changes. A number of the physical impacts of the climate change can’t be reversed at continental or global scales. The Intergovernmental Panel on Climate Change, having a medium confidence level concluded that with the global average temperature increase of 1 to 4 degrees C ( of 1990-2000),partial deglaciation of would take place over many centuries or millenniums.
Global warming effects across the world population will not evenly be distributed. Some areas may experience benefits from this while some will experience costs. Since greater levels of warming are taking place it is likely that the advantages will start decreasing and the costs will increase. The lower latitude and less developed areas will be at the greatest risk.
There are specific regions which are more vulnerable to Global warming effects. Due to the projected high rates of warming the Artic is more susceptible to warming. The continent of Africa,especially the sub-Saharan region, low ability to adapt to climate change and projected impacts. Any of the small islands are susceptible to being effected by global warming.
