How hot will your city be in 2100?

How hot will your city be in the coming decades? Climate change is already changing the cities of the world and temperatures are increasing according to the records of recent years.

2016 was one of the hottest years on record. 2021 and 2022 didn’t fall behind either. What temperatures will cities reach in the coming decades if global warming doesn’t stop?

All of us who inhabit the planet realize that summers are getting more rigorous, especially in cities. The global trend is for temperatures to continue rising at the end of the century if carbon emissions, which are responsible for climate change, are not contained.

Particularly in cities, this trend will be more noticeable, due to population growth and the well-known “heat island” effect. By the end of the century, cities will experience 14.8°C more than rural or vegetated areas, making them dangerous habitats for human life.

World population concentrated in cities

Currently, about 54% of the world’s population lives in cities, and by 2050 an increase of 2.5 billion people is expected. Taking into account the extra heat suffered by cities, this population growth may be a variable that increases temperatures even more.

O Non-governmental organization Central climate created a interactive chart to represent the future of cities and their temperatures and compares them with the current ones.

In this scenario, Madrid (Spain), for example, would have an average temperature of 36.4ºC in 2100 like Erbil (Iraq); Ottawa, Canada, could have the tropical climate of Belize City in the year 2100; Kabul (Afghanistan) could end up with temperatures like those found off the coast of Colombo (Sri Lanka) -28.4ºC-; Tokyo (Japan) would rise to 31.2°C on average in summer; Athens (Greece) would end up with temperatures like Faisalabad (Pakistan) of 37.6ºC; or Cairo (Egypt), like its neighbor Umm Durman in Sudan, which according to Central climate It would have an average of 44.3ºC, a temperature that no city on Earth currently suffers.

On average, the Earth’s temperature will increase by 4.8°C, but due to geographic variations, some cities will heat up much more. For example, Sofia (Bulgaria) will show the greatest change in overall temperature, as it would rise by around 8.4°C on average.

The increase in temperatures will be so great in the coming decades that there is no comparison possible with any city today. He will experience extreme heat that we have never experienced before.

Faced with this dangerous scenario for life on Earth, major cities have come together to lead the fight against climate change and commit to reducing emissions.

It’s almost too late to act.
