Climate change is a geophysical process, which runs independently from national boundaries. All countries are and will continue to be affected by its effects and impacts, though different locations will likely suffer from different problems (e.g., temperature, precipitations, extreme events, etc). And some areas might also benefit from a warming (e.g., Siberia might become more hospitable and suitable for economic exploitation). Within any given area, there will be winners and losers: to stick with polar regions, where mean average annual temperatures are expected to rise significantly more than in tropical regions, polar bears may disappear because they only can operate in cool climates, while humans (and mosquitoes!) might proliferate...

There is no such thing as a "climate change maximum": it all depends on what geophysical (or human) parameter you look at, over which spatial and temporal scales, what or who is being affected, etc., or even your own ethical values (those that guide your perception of what's worse). How do you compare the plight of inhabitants of small Pacific or Indian Ocean Island States, which will disappear from the map because of sea level change, with the melting of glaciers in large mountain ranges (and therefore the loss of clean drinking water for populations downhill), or changes in tropical storm tracks (which can destroy entire cities, as in Haiti)?

To explore such issues further, you may want to first become cognizant of the work of the work of the Intergovernmental Panel on Climate Change (IPCC)'s Fifth Assessment Report, available on-line at http://www.ipcc.ch/report/ar5/. Then, please consider sharpening and narrowing down your question(s) because no-one can meaningfully answer such a broad and fuzzy query...

Republic of the Maldives, if the sea rise becomes reality. It will be submerged under sea water.

I agree with Michel and if you narrow down the effect like sea level rise, Khan answer is correct.

A very debatable issue, but Prof. Khan's reply has logic. In lower Gangetic region, the rate is 3.18mm/yr

Island of Maldives and some islands of pacific oceans may submerged under  sea water if the sea level  rises due to melting of ice-sheets by global warming.

Dear Vinesh

In India historians have proved that the historical city of Dwaraka got submerged in the Arabian sea. In Chennai, near Mahabalipuram parts of the historical structures were submerged in the sea. There are many other instances in India where the sea has submerged land areas. 

I think climate change and global warming are global phenomena affecting all the nations and cautioning the governments to initiate steps to mitigate the ill effects and protect their nation's property and persons.

Best wishes.

Sea-level rise is not from melting of ice-sheets but the thermal expansion of the sea when the earth gets warmer

In Africa

the Sahelian countries already experienced a long rainfall shortage which has not ended yet. It started at the beginning of the 70s and was at its maximum during 1982-1984. Since then the seasonnality of rainfall has changed quite significantly as well as the interannual variability. In other West African countries a rainfall decrease is also evidenced since the same period. Even in Central Africa the rainfall distribution has changed significantly since the same period.

It seems that it all started during the 60's, at the same time when SST in the equatorial Atlantic began a rapid upward shift.
