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 Wednesday 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 and published in PLOS ONE on Wednesday.
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.
