Eric Klinenberg, a professor of social sciences at New York University, quoted by Euronews.green, says that "I don’t know a single city that is truly prepared for the worst-case scenario that some climate scientists fear."

While more accurate weather forecasts and media coverage definitely help mitigate the damaging effects of abnormal heat episodes, not all measures that work in a certain city will work well in another.

France is one of the better-prepared European countries, which implemented a public warning system after the deadly 2003 heatwave, which caused the deaths of 15.000 people, many of which didn't have access to air conditioning.

Germany implemented a similar system to prevent people from being taken down by the heatwave, while in Barcelona, building roofs were painted white to deflect the sun rays.

Ahmedabad in India and Chicago in the US are two other cities around the world which have heat-warning systems implemented, after they dealt in the past with such dangerous events.

Because each city is built differently with regards to the buildings, the streets and the transportation system, among other things, protection methods need to be adapted by the authorities.

Experts also say that elderly people, isolated and homeless ones are those who tend to suffer the most during this kind of heat-related episodes. Thus, hospitals tend to be strained during summer time, due to people coming in with heart attacks and kidney failures and other heat-related issues.

The electricity grid is also in danger in some places around Earth, where temperatures reach extreme highs or where the system wasn't designed to withstand such warm weather.

This year's June was reportedly the hottest sixth-month in many years globally, which is why mitigating the effects of heatwaves is critical for every country.

Spain is one country which takes into account banning outdoor work when an extreme heatwave is in effect, while some European cities opened public cooling centers for the population to take temporary shelter.

Some scientists also believe that green spaces could be of a great help, as they can help cut the deaths caused by heatwaves by over a third.
