“One thing that really jumps out is the need for international support for many of these parts of the world.” For most countries, exposure to – and costs from – climate change are already increasing. Over the past 10 years, storms, wildfires and floods alone have caused losses of around 0.3 per cent of GDP per year globally, according toThe World Meteorological Organisation also calculates that, on average, a weather-, climate- or water-related disaster has occurred somewhere in the world every day for the last 50 years, causing 115 daily deaths and over $US202 million in daily losses.
A study last year by a group of UK universities looking at a more extreme rise in global temperatures, predicted that more than 60 countries could see their ratings cut because of global warming by 2030.
