A new report indicates that Geneva is set to warm by as much as 2.5C in the 2020s and thirteen cities worldwide are projected to see “alarming” rises in temperature that could exceed 2C over the next decade or so.
The Belgian city of Leuven faces the highest potential increase among a hundred cities that were included in the report by the Urban Climate Change Research Network, based at Columbia University.
Cities that could see the steep temperature increases by the 2020s include Geneva in Switzerland (2.5C), Shenzhen in China (2.3C) and Tsukuba in Japan (2.3C), the study showed.
The new findings presented at United Nations-backed climate summit follow a UN draft report already causing alarm with projections that the global temperature rise is on track to exceed a 1.5C target included in the Paris pact to curb global warming.
The new data provides “foundation knowledge” for cities at the forefront of efforts to rein in the effects of global warming, said Cynthia Rosenzweig, an editor of the report and a researcher with Nasa.
Experts say storms, floods and other extreme weather events related to climate change are hitting cities much harder than scientists predicted.
“How will the cities know how they should develop their resilience plans unless they know what temperature projections, how the climate is supposed to change in their cities?” said Ms Rosenzweig during a press conference.
