The Asian Development Bank has warned that unabated climate change would have devastating consequences for economies in Asia and the Pacific.
The ADB released a new report on Friday about the impact of global warming.
It says the average temperature in Asia is projected to increase by 6 degrees Celsius by the end of this century under a business-as-usual scenario.
The report projects that this would lead to a decline of up to 50 percent in rice yield in some countries in Southeast Asia, causing serious food shortages.
Annual losses from flooding and other disasters will increase by nearly 9-fold by 2050 from 2005, to about 52 billion dollars worldwide.
The report also estimates that 13 of the top 20 cities with the highest growth of annual flood losses from 2005 through 2050 are concentrated in Asia. Among those cities are Bangkok, Guangzhou in southern China, and Nagoya in central Japan.
It says global climate change is the biggest challenge civilization faces in the 21st century.
To mitigate the impact of climate change, the ADB is urging countries to implement the commitments laid out in the Paris Agreement. It says otherwise Asian economies will be hit with devastating damage.
