According to the European Union’s Copernicus Climate Change Service (C3S), last month marked the hottest June ever recorded, continuing a trend of record-breaking temperatures. This streak of exceptional heat has persisted since June 2023, with each month consecutively becoming the hottest on record compared to previous years.
Some scientists suggest that 2024 is on course to be the hottest year globally recorded.
“I now estimate that there is an approximately 95% chance that 2024 beats 2023 to be the warmest year since global surface temperature records began in the mid-1800s,” said Zeke Hausfather, a research scientist at Berkeley Earth.

The natural El Niño phenomenon, which warms the eastern Pacific Ocean, typically raises global average temperatures. This influence has waned recently, leaving the world in neutral conditions before potentially cooler La Niña conditions emerge later this year.
However, the primary driver of climate change remains greenhouse gas emissions from burning fossil fuels. Despite pledges to mitigate global warming, countries have collectively failed to reduce these emissions, resulting in steadily rising temperatures over decades.
According to C3S, in the 12 months leading up to June, the global average temperature reached its highest recorded level for any such period, measuring 1.64 degrees Celsius above the average from the pre-industrial period of 1850-1900.

Recent data indicate that 2024 has the potential to surpass 2023 as the hottest year on record.
Scientists attribute this likelihood to a combination of human-caused climate change and the natural weather phenomenon El Niño, both of which contributed to record-high temperatures observed thus far in the year.
