National Heatwave Plan to be activated on 18 June

Vulnerable groups have a greater risk of dying from heat, also in Amsterdam
Climate change will lead to more tropical days and warm nights in summer, and fewer cold days in winter. In the Netherlands the risk of dying increases when it is hot. The municipality of Amsterdam wants to know what this means for their residents. Therefore, RIVM investigated whether there was an association between temperature and mortality in Amsterdam between 2007 and 2019.

National Heatwave Plan evaluation: substantial attenuation in risk of dying from heat since 2010
The risk of dying on hot days has substantially attenuated since 2010 in the Netherlands. The estimated number of heat-related deaths decreased from 7,000 in the 2000–2009 period to 4,300 in the 2010–2019 period. This is the outcome of a study conducted by RIVM.
