Extreme weather-related disasters aren't new, but they are on the increase.
Globally, the number of climate-related disasters has more than tripled since 1980. This year we've seen Hurricanes Harvey, Irma and Jose wreak a path of destruction in the US, we've seen thousands die and millions displaced in South Asian floods. Australia's summer broke 205 records, while Europe experienced a deadly heat wave amid warnings of worsening weather disasters on the continent.
