Various other of David’s graphs, shown on an event with the Monday of your Ecological Safety Ministry’s Environment Alter Preparedness Directorate, showed what amount of months from inside the a year during the Tel Aviv when heat exceeded 29 values Celsius (85°F), anywhere between 1964 and you may 2019.
