Bangladesh, India and the Democratic Republic of Congo (DRC) are among 30 countries with "extreme" exposure to climate shift, according to a ranking of 193 nations by Maplecroft, a British firm specialising in risk analysis.
Five Southeast Asian nations — Indonesia, Myanmar, Vietnam, the Philippines and Cambodia — are also in the highest category, partly because of the rising seas and increasing severe tropical storms.
Maplecroft's tool, the Climate Change Vulnerability Index (CCVI), looks at exposure to extreme weather events such as drought, cyclones, wildfires and storm surges, which translate into water stress, loss of crops and land lost to the sea.
How vulnerable a society is to these events is also measured, along with a country's potential to adapt to future climate change-related hazards.
Of 30 nations identified in the new report as at "extreme" risk from climate change, two-thirds are in Africa and all are developing countries. Africa is especially exposed to drought, severe flooding and wildfires, the report says.
"Many countries there are particularly vulnerable to even relatively low exposure to climate events," said Charlie Beldon, coauthor of the study.
Weak economies, inadequate healthcare and corrupt governance also leave little margin for absorbing climate impacts.
At the other end of the spectrum, Iceland, Finland, Ireland, Sweden and Estonia top the list of nations deemed to be least at risk. With the exception of Israel and oil-rich Qatar and Bahrain, the 20 least vulnerable countries are in northern and central Europe. China and the US, the world's No1 and No2 carbon emitters — are in the "medium" and "low" risk categories, respectively. In a parallel analysis of major cities at risk, Maplecroft pointed to Dhaka, Addis Ababa, Manila, Kolkata and the Bangladesh city of Chittagong as being most exposed.
Three other Indian metropolitan areas — Chennai, Mumbai and New Delhi — were listed as being at "high" risk.
"Vulnerability to climate change has the potential to undermine future development, particularly in India," Beldon observed.
Recent studies — reviewed in a special report by the UN's Intergovernmental Panel on Climate Change (IPCC), due out next month — point to strengthening evidence of links between global warming and extreme weather events.
