If the recent heatwave in Europe was any indication, the world is going to face several heatwaves in the coming years. According to the projections, the world’s major cities will see a drastic increase in temperatures by 2050.
London’s climate will be similar to today’s Madrid. Paris will resemble Canberra, Stockholm would be like Budapest, and Moscow will be like Sofia.
According to the new analysis, climate change will be more dramatic for the world’s major tropical cities like Jakarta, Kuala Lumpur, and Singapore. These cities will see extreme weather incidents and severe droughts.
These projections have been compiled in a study undertaken by scientists from ETH Zurich and published in PLOS ONE. Researchers assessed the climate of world’s 520 major cities employing 19 variables that show variability in precipitation and temperature.
The study made future projections using established models that were intentionally optimistic. For instance, it assumed carbon dioxide emissions would decrease by 2050 as a result of the implementation of green policies. Even then the world is expected to heat up by an average of 1.4 degrees Celsius in mid 21st century.
The team also compared the climate similarity between current and future cities. In the northern hemisphere, cities will resemble places located over 1000 km (600 miles) south near the equator by 2050.
Cities closer to the equator would not undergo drastic warming, but they will be prone to extreme droughts and rainfall. In total, 77 percent of the world’s cities will witness a ‘striking change’ in climatic conditions while 22 percent will see ‘novel’ conditions, i.e., conditions not seen before.
In Europe, winters and summers will grow warmer with an average increase of 4.7 Celsius and 3.5 Celsius respectively.
