Pakistan, Guatemala and Colombia have covered up the charts in 2010 for countries that were worst affected by extreme weather events, 'risk index of. But over a span of 20 years, who were most vulnerable countries were Bangladesh, Myanmar and Honduras, secondary activities of the UN climate talks in Durban. The index, compiled by a European NGO called Germanwatch, is an indicator of which countries published annually-is more in need of shoring on defenses against floods, storms, droughts and heat waves, that climate scientists the UN says will exacerbate this century. It factors in the cost of the event in terms of human lives and in terms of losses in absolute dollar terms, but also the cost of the second level of prosperity of the country. Pakistan in 2010 was hit by worst floods in its history, with 84 of 121 districts affected, Germanwatch said. Guatemala has been rocked by hurricanes and the flood has affected Colombia. Russia has ranked fourth on the list, after a heat wave in July that caused the fires of forest and peat massifs and indirectly led to 55,000 deaths. Scientists are reluctant to pin the events of time only to longer-term trends of climate change. But Germanwatch, citing a study in the American journal Proceedings of the National Academy of Sciences-revised (PNAS), said that the Russian heatwave could be well regarded as an exception.Throughout the world, more than 710,000 people died from 1991 to 2010 from 14,000 incidents of extreme weather, the incurring economic losses in terms of today to more than 2.3 trillion dollars, he said. When viewed through this period of 20 years, not one country in the top 10 features developed for the risk of climate.Only one - Russia - featured in the top 20 and this was as a result of the 2010 heat wave. "These results highlight the particular vulnerability of poor countries to climate risks, despite the fact that the absolute monetary damages are much higher in rich countries.
