In Southeast Asia, people know well the risks that extreme weather can bring, and they worry that a warmer climate will increase those risks.
When Typhoon Ketsana hit Manila this year, the crowded city's planners were stunned at the amount of rain that poured down in a short time. Houses here sit close to the ground, even though the land is lower than a lake nearby.
"The most concerned extreme events in Southeast Asia is probably storm - typhoon and tropical storm," said climate scientist Anond Snidvongs.
Dr. Anond Snidvongs, who has studied climate change for more than a decade, has analyzed storm data over the past 60 years. Storm frequency, he says, comes in cycles of 30 years. But, he warns, warmer global temperatures could bring more, and bigger, storms.
