Global temperature unprecedently exceeds 1.5C warming limit over 12-month period

For the first time on record, global warming has exceeded temperatures of 1.5 degrees Celsius (2.7 degrees Fahrenheit) over a 12-month period, European climate monitors have said, in what scientists called a “warning to humanity”.

The European Union’s Copernicus Climate Change Service (C3S) reported the run of exceptional heat on Thursday, measuring temperatures between February 2023 to January 2024 to record the highest 12-month global temperature average on record.

Storms, drought and fires lashed the planet as climate change, as well as the El Nino weather phenomenon that warms the surface waters in the eastern Pacific Ocean, made 2023 the planet’s hottest year in global records going back to 1850.

The extremes have continued into 2024, C3S said, confirming the year-long warming of 1.52C above the 19th century benchmark.
