Work on climate change has largely focused on preventing it from getting worse, but as a new RBC report points out, businesses are also starting to think more about potential spending on adaptation and preparation as the costs of disasters pile up. The report says that extreme weather and natural disaster costs already totalled US$368 billion last year, 14 per cent above the long-term average since 2000, and that this year could match or exceed the total. The trend is expected to get worse, because as the report notes there’s expected to be a 2.7 degree rise in average temperatures by 2100 based on current global policies and actions, while an optimistic scenario pegs the rise at 1.9 degrees. The costs stemming from rising temperatures are leading to more attention in boardrooms, with the report noting mentions of climate change on the rise in both U.S. and Asia.
