… [M]any scientists warn that this year or next could see world temperatures pass the 1.5C threshold that was set by the IPCC as being the upper limit for a rise in global warming that would avoid the planet passing through meteorological tipping points that could bring irreversible changes to world weather patterns.
The consequences of a new record heatwave occurring very soon will be profound and dangerous, add scientists. More than 61,000 people are now estimated to have died as a result of the soaring temperatures that gripped Europe last summer.
Given the likelihood of that record being broken this year – or next year at the latest – there is a strong chance that 2022’s grim death toll will be topped very soon with Mediterranean nations such as Greece, Spain and Italy likely to suffer the worst consequences.
According to UN secretary general António Guterres “climate change is out of control”. He warned that if the world persisted in delaying key measures needed to limit fossil fuel emissions, it would move “into a catastrophic situation”.
Many scientists have reacted to this alarm with rueful resignation. They have warned for more than 30 years that continued burning of fossil fuels would trigger the heatwaves that we are now experiencing.
“We should not be at all surprised with the high global temperatures,” Prof Richard Betts, climate scientist at the Met Office and University of Exeter, told the BBC. “This is all a stark reminder of what we’ve known for a long time, and we will see ever-more extremes until we stop building up more greenhouse gases in the atmosphere.”
