At-risk communities in Asia are warning that they have ¡°no hope¡± of coping with more climate catastrophes and some even fear ¡°extinction¡± if the world does not act quicker, after the U.N. said global warming was close to being out of control.

Climate experts are also concerned the effects could worsen inequalities in a region where many people rely on natural resources for their livelihoods, pushing more into poverty.

The U.N. climate science panel on Monday warned in a major report that the average global temperature will likely cross the 1.5-degree Celsius warming threshold within the next 20 years ¡ª bringing stronger droughts, heat waves, floods and storms.
