In a startling revelation, new data from the European Copernicus climate service indicates that 2024 has become the hottest year on record, surpassing the symbolic 1.5°C mark above pre-industrial levels. This marks a critical moment in the global climate crisis, as scientists and leaders worldwide grapple with the implications of this unprecedented warming.
The 1.5°C figure, long considered a key threshold in climate negotiations, was breached for the first time in a single calendar year. Although this does not yet signify a permanent crossing of the international target—which refers to a long-term average—it underscores the pressing need for immediate action. UN Secretary-General António Guterres described the trend as a “climate breakdown,” urging nations to “exit this road to ruin” and accelerate efforts to curb emissions.
The Copernicus data reveal that global temperatures in 2024 averaged 1.6°C above pre-industrial levels, breaking the previous record set in 2023 by over 0.1°C. This development has now placed the past decade as the hottest on record, highlighting the relentless impact of human-induced climate change.
Samantha Burgess, deputy director of Copernicus, emphasized that “the largest contribution impacting our climate is greenhouse gas concentrations in the atmosphere.” While natural phenomena like El Niño have played a role, the dominant driver remains human activity.
The ramifications of this warming were felt globally, with devastating weather events such as severe droughts in South America, intense rainfall in central Europe, and powerful storms in North America and South Asia. Dr. Gabriel Pollen from Zambia noted the profound impact of the country’s worst drought in a century, stating that “no area of life and the economy is untouched.”
The scientific community warns that even marginal increases in global temperatures can lead to more extreme weather events. Zeke Hausfather of Berkeley Earth highlighted the critical nature of every fraction of a degree, stating, “It’s not like 1.49°C is fine, and 1.51°C is the apocalypse—every tenth of a degree matters.”
Despite the alarming data, scientists maintain that there is still a window for action. Prof. Piers Forster of the UK’s Climate Change Committee called the temporary breach a “foretaste of life at 1.5°C” and urged for intensified efforts to reduce emissions. Carlo Buontempo, director of Copernicus, reinforced this sentiment, said+, “The future is in our hands: swift and decisive action can still alter the trajectory of our future climate.”
As the world contends with these challenges, the potential rollback of climate commitments by political leaders like Donald Trump and Argentina’s president adds further complexity to global climate diplomacy. Nonetheless, figures like the UK’s climate minister Kerry McCarthy emphasize the economic opportunities in addressing the crisis, advocating for a transition that fosters job creation and energy security.
The data from 2024, marking a pivotal moment in the climate crisis, demands urgent attention and collective action to mitigate future risks and safeguard the planet for future generations.
