Scientists blame rising temperatures for the destruction caused by Typhoon Kalmaegi in Southeast Asia.

Scientists warn that extreme weather events will only increase in frequency as temperatures continue to rise. At least 188 people were killed by Typhoon Kalmaegi in the Philippines. It also caused extensive damage to farmland and infrastructure across the archipelago. After landing in central Vietnam on Thursday night, the storm destroyed homes and uprooted many trees. The path of destruction of Kalmaegi coincides with the meeting of more than 190 delegates in Brazil's rainforest city of Belem for the latest round in climate talks. Researchers claim that the failure of leaders around the world to control greenhouse gas emission has resulted in increasingly violent storms.

Ben Clarke is an extreme weather researcher from London's Grantham Institute on Climate Change and Environment. He said that the sea surface temperatures over the South China Sea and the Western North Pacific are both unusually warm.

The trend in sea surface temperature is clearly linked to global warming.

WARMER WATERS PACK 'FUEL' INTO CYCLONES

Scientists say that while it's not easy to link a specific weather event with climate change, in general, higher sea surface temperatures accelerate the evaporation and add more "fuel" to tropical cyclones.

Gianmarco Megaldo, researcher at National University of Singapore, said that climate change increases typhoon intensities primarily through warming ocean surface temperature and increasing atmospheric moisture.

He added that "although this doesn't mean every typhoon is going to get stronger, it does increase the probability of storms with greater intensity and heavier rains, as well as stronger winds."

Mengaldo said that while the data doesn't indicate that tropical storms have become more frequent, the intensity has increased. He co-authored a report on the role climate change played in the September Typhoon Ragasa. In the Philippines, six deadly typhoons hit in one month. Four tropical cyclones formed in November in a rare event, suggesting storms are now occurring over shorter periods.

Drubajyoti Samantha, a climate researcher at Singapore's Nanyang Technological University, said that even if the total number of cyclones doesn't increase dramatically each year, their proximity to seasons and impact potential may increase.

He added that "Kalmaegi serves as a reminder of this emerging risk pattern."

BACK-TOBACK SEVERE STORMS CAUSING MORE DESTRUCTION

Feng Xiangbo is a tropical storm scientist at the University of Reading in Britain.

He said that "back-to-back" storms could cause more damage.

This is because the soils are already saturated and rivers are full. Infrastructure is also weakened. Even a weak storm can cause catastrophic damage at this time.

Feng and Mengaldo both warned that other regions may also be at risk, as storms could form in new locations and follow different paths and intensify.

Feng said that recent studies show the coastal areas affected by tropical cyclones are growing significantly due to storm surges and ocean wave growth.

This, along with the mean sea level increase, poses a serious threat to low lying areas, especially in the Philippines and on Vietnam's shallow coast shelves. (Reporting and editing by Saad Saeed; David Stanway)
