From the Himalayas to the Arctic, global warming has made summers longer and drier, with significant impacts on the landscape,media New Atlas reported. A good example is Australia, which had the hottest and driest year on record and then suffered the devastating wildfires at its end. A team of researchers assessed this alarming trend and came up with figures on the current start and end of the Australian summer, finding that Australia now spends a month longer in summer than the mid-20th century benchmark.
The analysis was carried out by researchers at the Australian Institute of Research think-tank, who used temperature data from the Australian Government’s Bureau of Meteorology. The researchers used the average daily temperature from 1950 to 1969 as a benchmark and compared it with the average daily temperature from 1999 to 2018 to determine how climate change affected the Australian season.
In the process, the team looked at the daily temperatures at the beginning of different seasons and found that all four of the seasons were getting hotter across Australia. Over the past two decades, the team found that summer was a full 31 days longer than the benchmark average, two weeks earlier and two weeks late. The team found that winter is also more than three weeks shorter.
The team also looked at the latest time periods between 2014 and 2018 and found greater differences in seasonal variations. The average summer time is nearly 50 percent longer than the average in the mid-20th century, and about twice as long as the winter of the same period.
“In the 1950s, summer was considered a regular three months, and now it lasts from mid-November to mid-March,” said Richie Merzian, director of the Climate and Energy Program at the Australian Institute. “After experiencing the hottest summer on record, older Australians are heard to claim that summer is different from what they have experienced in the past.” They are right. “
