For the first time in recorded history, global warming breached the critical 1.5°C threshold in 2024, marking an alarming new chapter in the climate crisis. According to data from the European Earth Observation Programme Copernicus, the average surface temperature last year soared to 1.6°C above pre-industrial levels, making 2024 the warmest year ever documented.
This milestone also marked a grim first: average temperatures exceeded the targets outlined in the 2015 Paris Agreement, which aimed to cap warming at “well below” 2°C and ideally limit it to 1.5°C above pre-industrial levels. Over the past decade, from 2015 to 2024, each year has ranked among the ten hottest on record. Notably, every continental region experienced record-breaking heat in 2024—except Antarctica and Australasia.

Carlo Buontempo, director of the Copernicus program, explained to the Financial Times that last year’s unprecedented wave of climate disasters—from severe floods to scorching heatwaves—was no statistical fluke. Instead, these events were direct consequences of human-driven climate change, exacerbated by rising levels of carbon dioxide and methane.
“Reaching the 1.5°C threshold is like toppling the first domino in a catastrophic chain reaction. We’re toying with forces we can barely control. Every fraction of a degree pushes us closer to more violent storms, prolonged droughts, and increasingly lethal heatwaves,” warned Patrick McGuire, a climate expert from the University of Reading, in an interview with the FT.
While human activity remains the primary driver of these changes, the now-concluded El Niño cycle also played a role in last year’s extreme temperatures. With El Niño officially ending in June 2025 is expected to be slightly cooler, though the underlying trend of rising temperatures remains unbroken.
Adding to the urgency, 2024’s record heat coincided with a worrying global shift in climate priorities. Some businesses scaled back their sustainability initiatives, and political rhetoric in the United States under President-elect Donald Trump signaled a potential retreat from the Paris Agreement.
As the world grapples with these realities, 2024 stands as a stark reminder: the climate crisis is no longer a distant threat but a present-day emergency demanding immediate and unified global action.
