"All this will affect the balance of energy in nature in the long term," Li Xichen, a senior researcher at the Institute of Atmospheric Physics, an affiliate of the Chinese Academy of Sciences, says in Beijing of oceanic and atmospheric circulations.

The world's coastal areas will likely take the worst hit.

Li, who has studied the Antarctic and Arctic oceans, says in western Antarctica, for instance, surface temperatures have also gone up by 5 degrees.

The Antarctic region contains some 500 gigatons of freshwater in glaciers.

With glacial melting potentially irreversible, one sure way to deal with the situation is pursuing sustainable development. The 2015 Paris Agreement, which seeks to rein in global warming, has been ratified by most countries. In June, US President Donald Trump announced his country's exit from the accord, a move widely criticized by governments and scientists.

Some experts are suggesting climate modeling as a supplement to emission cuts to combat global warming.
