That's a very bad take, as it covers only fires in Corfu specifically (and that see other replies regarding that), but not the extreme heat in general over Greece, Italy ( https://www.theguardian.com/world/2023/jul/25/italy-wildfire... ) and most of the rest of Europe, and the other fires in other parts of Greece, e.g.
Rhodes https://www.bbc.co.uk/news/uk-66297476 , Evia https://www.theguardian.com/world/2023/jul/24/greece-wildfir... etc.
Reducing Europe's summer 2023 to "The Greek wildfires" - fires plural - and then to "some arson on Corfu" is ridiculous minimisation.
