In 2004, a calamitous tsunami killed an estimated 36,000 people as 30-metre high walls of water lashed its low-lying coastal plains.Triggered by an earthquake near the Indonesian island of Sumatra, that can’t be blamed on climate change. That concern suffuses a seven-page document delivered to the UN on Thursday. But it underlined the country’s vulnerability to natural disasters, some of which will be stoked by warming temperatures in future. Government disaster relief stood at US$130 million between 2007 and 2011. Officials fear the bill could grow as global warming makes intense storms or failed monsoons more likely.Sea-level rise menaces Sri Lanka’s tourism and fishing industries, and the export of agricultural produce, the document warned.Some threats can be reduced with investment in sea defences or drought-resistant crops, for example. Officials calculate $420 million is needed for climate-proofing over the next decade. “Sri Lanka is largely affected with climate induced extreme weather events and slow onset disasters,” read its national contribution to a global warming treaty due to be finalised in December.“Losses and damages (L&D) due to these disaster events are heavy, creating a huge pressure on the economy and public spending.” Envoys from 195 nations are crafting a new global warming treaty to be finalised in Paris in December. National pledges form the backbone of the deal.Sri Lanka’s plan outlines greenhouse gas cuts to play its part.It plans to shave 7% off forecasts of future emissions in 2030. That can rise to 23% with help from international partners.While its energy demand is on track to double within 20 years, it said it will tackle a dirty transport system which belches half of the energy sector emissions.It plans greener vehicles, enhancing its public transport system and laying electric railways.Biodiverse rainforest and mangroves, which cover 30% of the country, will be increased to 32% to act as carbon sinks. (Courtesy Climate Change News) For the developing country of 20 million people, which emits just 0.1% of global greenhouse gas emissions, it is a matter of fairness.“Sri Lanka intends to join hands to develop a fully-fledged Warsaw International Mechanism on Loss and Damage to address the loss and damage issues and in parallel develop an appropriate local mechanism,” reads a highlighted box in the climate pledge, or INDC in UN lingo.That is a tall order. Rich countries have pushed back on the vexed issue, worried they would be opened up to a litany of lawsuits. Analysts forecast that “loss and damage” will get just a fleeting mention in a new climate agreement. Yet inevitably, there will be impacts people cannot adapt to. Sri Lanka is rallying with its low-lying cousins to force climate change’s wealthy culprits to pay out damages.
