Weather catastrophes drive most of $225 billion cost of perils in 2018

Aon Benfield

A new Aon report reveals that 394 extreme weather events in 2018 generated economic losses of USD 225 billion. Of that total, private sector and government-sponsored insurance programs covered USD 90 billion. Tropical cyclones drove most of these losses, with 2017 and 2018 resulting in the costliest back-to-back years on record solely due to weather-related events.

  • UK: Two- to three-fold increase in heatwave occurrence and severity

    Univ of Warwick

    New research reveals that there has been a two- to three-fold increase in the average frequency and duration of UK heatwaves since 1878. Using observations of daily temperatures and a new and independent verification for climate models, the research finds that week-long heatwaves seen on average every five years would now typically exceed 28°C.

  • Greenland ice melting rapidly, study finds

    Ohio State Univ

    Scientists concerned about sea level rise have long focused on Greenland’s southeast and northwest, but new research reveals that the largest sustained ice loss from early 2003 to mid-2013 came from Greenland’s southwest. In turn, the ice is melting faster than previously thought and could have serious implications for coastal cities and island states worldwide.
