For global warming, scientists today based on an analysis of optimistic predictions pointed out that by 2050, London’s climate will become more like Canberra, like today’s Madrid, Paris. In Moscow, it is like living in Sofia, the capital of Bulgaria.
In major cities such as Kuala Lumpur, Jakarta and Singapore, climate change will be more dramatic, and unprecedented climates may cause extreme weather events and severe drought.
The science team at ETH Zurich uses 19 variables that reflect temperature and rainfall changes to examine the climate of 520 major cities around the world. Their report was published in the Journal of the Public Library of Science (PLOS ONE).
The predictions of the scientific team are based on a set of deliberately optimistic existing models, that is, it assumes that global carbon dioxide emissions will stabilize in the current century due to the implementation of green energy policies by countries, and assume that the average global temperature increase is 1.4 degrees Celsius.
The scientific team then compares the current and future climate conditions of major cities, but the results are terrible.
In the northern hemisphere, the climatic patterns of major cities in 2050 will be more similar to more than 1,000 kilometers southward toward the equator.
Cities close to the equator will not see too much warming, but there will likely be more extreme drought and rainfall.
Overall, 77% of global cities will experience significant climate change, and 22% will experience “new” environments, such as those that have never been seen before.
In Europe, the summer and winter seasons will be more warm, and the temperature increase will reach 3.5 degrees Celsius and 4.7 degrees Celsius respectively.
The model used in the report is not new, its purpose is to consolidate information and motivate decision makers to take action.
The main author, Jean-Francois Bastin, told AFP: “The focus of this report is to try to make everyone aware of the consequences of climate change.”
He said: “For more than 30 years, most people have agreed to the fact of climate change, and they agree that climate change is caused by human activities. But we have not yet translated this consensus into global action.”
