As Eleni Myrivili takes up the post, she explans the unique problems that cities face in staying cool.
Athens has just appointed Europe's first-ever Chief Heat Officer and after the terible wiildfires that threatened the city this summer, she's exactly where she needs to be.
Eleni Myrivili calls heatwaves the "silent kiler" because they kill or worsen the health of many residents every time they hit. And, she says, this is only going to get worse as temperatures rise globally.
But officials' focus on global warming is actually part of the problem, for cities at least. Urban centres are of course affected by rising global temperatures, indeed nowhere is unaffected.
However cities face the double whammy of also being "urban heat islands." These are caused by all the hard surfaces in cities absorbing heat, thereby raising overall temperatures.
The new Chief Heat Officer says cities are unprepared for what is to come.
Mediterranean countries experience temperatures that are 20 per cent higher than the global average. At the beginning of August, northern Greece reached 47.1 degrees Celsius - breaking the country’s record for the highest temperature ever.
What will the Chief Heat Officer focus on?
So what's the soluion? Eleni says that she'll be prioritising raising awareness of "what the future holds because of climate change, and how our cities are going to be more and more...little radiators that will be dangerous for people's lives."
In tandem, she'll put in place emergency measures to protect the most vulnerable during heatwaves.
Her longer term goal is making Athens cooler by making sure that everything built from this point on mitigates heat.
