[Ambassador report] [Free report] Dramatic warming projected in world's major cities by 2050

By the year 2050, London's climate will resemble Madrid's today; Paris will be more like Canberra; Stockholm like Budapest and Moscow like Sofia, according to a new analysis published that relied on optimistic projections.

The changes will be even more dramatic for the world's major tropical cities like Kuala Lumpur, Jakarta, and Singapore which will experience unprecedented climate conditions, resulting in extreme weather events and intense droughts. The study was carried out by scientists from ETH Zurich.

Researchers examined the climate of the world's 520 major cities using 19 variables that reflect variability in temperature and precipitation. Future projections were estimated using established modeling that was intentionally optimistic, meaning it assumed carbon dioxide emissions would stabilize by the middle of the century through the implementation of green policies, with a mean global temperature increase of 1.4 Celsius.

The team then compared climate similarity of current and future cities to one another, and the results make for dire reading. Across the northern hemisphere, cities in 2050 will resemble places that are over 1,000 kilometers (600 miles) further south towards the equator. Those closer to the equator won't see drastic warming but will likely have more extremes of drought and rainfall.

Overall, 77 percent of the world's cities will experience a "striking change" in climate conditions, while 22 percent will experience "novel" conditions -- ie something that has never before been encountered.

In Europe, summers and winters will get warmer, with average increases of 3.5 celsius and 4.7 celsius, respectively. While the modeling used in the analysis is not new, the purpose of the paper was to organize that information in a way that will inspire policy makers to act.

    Hello Sumit

    This report came to a big shock to me. That said, it's even surprising that this estimate was based on optimistic model. I can't even imagine what it would be like if carbon dioxide emissions are unabated in the future. We must beef up our efforts to stop the climate change.
    Thank you for sharing this great report.

    Hi Sumit,

    Thank you for your report on this interesting topic. This summer, Europe has suffered from extremely high temperatures and it actually had caused many deaths for its abnormal climate. It is shocking to read that dramatic warming is projected in major cities by 2050 and I hope countries can work together to combat this climate change. Great report.
