June 2024 was the hottest June on record, the European Union’s climate change monitoring service said on July 8, continuing a streak of exceptional temperatures that some scientists said puts 2024 on track to be the world’s hottest recorded year.
Every month since June 2023 – 13 months in a row – has ranked as the planet’s hottest since records began, compared with the corresponding month in previous years, the EU’s Copernicus Climate Change Service (C3S) said in a monthly bulletin.
The latest data suggests that 2024 could outrank 2023 as the hottest year since records began after human-caused climate change and the El Nino natural weather phenomenon both pushed temperatures to record highs in the year so far, some scientists said.
“I now estimate that there is an approximately 95 per cent chance that 2024 beats 2023 to be the warmest year since global surface temperature records began in the mid-1800s,” said Dr Zeke Hausfather, a research scientist at Berkeley Earth.
The changed climate has already unleashed disastrous consequences around the world in 2024.
More than 1,000 people died in fierce heat during the haj pilgrimage in Mecca in June.
Heat deaths were recorded in New Delhi, which endured an unprecedentedly long heatwave, and among Greek tourists.
Dr Friederike Otto, a climate scientist at Imperial College London’s Grantham Institute, said there is a “high chance” that 2024 will rank as the hottest year on record.
“El Nino is a naturally occurring phenomenon that will always come and go. We can’t stop El Nino, but we can stop burning oil, gas and coal,” she said.
The natural El Nino phenomenon, which warms surface waters in the eastern Pacific Ocean, tends to raise global average temperatures.
This effect subsided in recent months, with the world now in neutral conditions before cooler La Nina conditions are expected to form later in 2024.
Greenhouse gas emissions from burning fossil fuels are the main cause of climate change.
