The recent wildfires in Greece started on Sunday 11 August in Varnavas, 35 kilometres (22 miles) north of Athens. By the time they were brought under control three days later, they had reached the capital’s suburbs, having burnt through 25,000 acres of forest.
Though the fires fortunately did not get fully into Athens, it was a close call. Similar extreme weather events – whether wildfire, drought, storm, flood or heat dome – are now seen on a near-daily basis somewhere around the world, and are often more intense than even a couple of decades ago. They are the most visible elements of climate change’s shift into climate breakdown.
We are also seeing clear worldwide changes. Last year was exceptionally hot – the hottest year since accurate weather records were first kept in the 1880s – but this year is perhaps more worrying. 2023 was an El Niňo year; one in which the sea surface temperature warms by 0.5°C above the long-term average. It’s a climate phenomenon that occurs every two to seven years and leads to temporary air temperature increases across much of the world in those years.
