The European Copernicus climate service reports that 2024 has become the first calendar year to exceed a 1.5C temperature increase, emphasizing the urgent need for global emissions reductions as climate records are broken.
2024 Marks Critical Year in Global Warming as Temperatures Surpass 1.5C Threshold
2024 Marks Critical Year in Global Warming as Temperatures Surpass 1.5C Threshold
New data reveals 2024 as the hottest year on record, nearing the crucial 1.5C warming limit set by international agreements.
Given recent climate data, the world has taken a significant step toward exceeding the 1.5C global warming threshold, as indicated by findings from the European Copernicus climate service. Announced on Friday, this alarming information marks 2024 as not only the hottest year recorded but also the first calendar year to surpass this symbolic limit. The year saw average temperatures approximately 1.6C above pre-industrial levels, a jump of over 0.1C from 2023—the previously warmest year.
While this data does not mean that the world has officially surpassed the long-term target of 1.5C, it draws the globe much closer to that reality, especially as fossil fuel emissions continue to rise. United Nations Secretary-General António Guterres labeled this streak of heightened temperatures as "climate breakdown" in a recent New Year’s address, urging nations to undertake drastic cuts to greenhouse gas emissions by 2025.
The observations from Copernicus reflect a troubling trend: the last decade has recorded the ten hottest years on record. Global warming in 2024 was largely attributed to human-induced emissions of greenhouse gases, which remain at unprecedented levels, coupled with the influence of the El Niño weather pattern, which occurred earlier last year. Samantha Burgess, deputy director at Copernicus, pointed out that greenhouse gases are overwhelmingly the main driver of the climate crisis.
The 1.5C figure first agreed upon in the 2015 Paris Agreement has become a critical benchmark for climate discussions, especially for vulnerable nations facing severe threats from climate-related impacts. A UN report from 2018 highlighted that surpassing the 1.5C threshold could lead to severe risks including extreme heatwaves, rising sea levels, and biodiversity loss.
Experts caution that while it is difficult to pinpoint the exact moment when the world will permanently cross the long-term 1.5C barrier, the current trajectory suggests we may reach that point by the early 2030s. Zeke Hausfather, a climate scientist, explains that every fraction of a degree matters, as even a small increase can result in more severe weather conditions.
Throughout 2024, areas such as West Africa experienced extreme heat, parts of South America faced severe drought, and central Europe dealt with intense rainfall. These events have been indirectly linked to the ongoing climate crisis, with destructive wildfires currently affecting Los Angeles exemplifying the heightened risks associated with climate change.
Notably, environmental conditions have also indicated unprecedented levels in sea surface temperatures and atmospheric moisture. While the El Niño effect was anticipated to elevate temperatures uniquely, the extent of the recent records caught many scientists off guard, indicating a possible quickening of climate change.
Despite the alarming data, climate experts assert that humans still possess the means to influence the future of our climate. Dr. Hausfather expressed that although the 1.5C limit seems increasingly unattainable, there remains the potential to cap warming at levels like 1.6C to 1.8C this century—significantly better than projected increases to 3C or 4C if fossil fuel consumption remains unchecked. The urgency for immediate action is more pronounced than ever as climate impacts intensify globally.
