The combined impact of climate change and expanding human population means that tropical cyclones will cause more than four times the damage in 2100 than they do today, increasing from $26 billion to $109 billion. New research published in Nature Climate Change shows that as the population grows to 9 billion people, something expected to happen by perhaps 2040, more people and more infrastructure will be put in the path of tropical cyclones. That alone is projected to double the damage from these storms, $56 billion by the end of the century. Climate change is project to nearly double again the damage cyclones cause, adding $53 billion a year to extreme weather bill. For full story, click here.
