2024 Marks a Turning Point in Global Temperature Rise: Breaking the 1.5C Threshold

New data reveals that 2024 has become the first year to approach the critical 1.5°C global warming limit, prompting urgent calls for climate action.


The European Copernicus climate service reports that global average temperatures for 2024 reached approximately 1.6°C above pre-industrial levels, marking it the hottest year on record. This milestone raises concerns about the potential breach of the long-term 1.5°C target that was established in global climate agreements.

The planet has moved significantly closer to exceeding the critical threshold of 1.5 degrees Celsius, according to new data from the European Copernicus climate service. As of 2024, it has become the first year on record to suggest temperatures may have surpassed this key limit, based on an average of 1.6°C above pre-industrial levels. This year's data appears to affirm a troubling trend, as it breaks the previous record set in 2023 by just over 0.1°C.

Despite the alarming statistics, it is important to clarify that the international 1.5°C target, agreed upon in the 2015 Paris Agreement, refers to a long-term average rather than an annual figure. Therefore, while 2024 stands out, it does not necessarily mean that the goal has been definitively breached. However, it highlights the rapid rise in temperatures driven by human activity, primarily fossil fuel emissions.

United Nations Secretary-General António Guterres characterized the recent temperature records as indicative of a "climate breakdown," urging nations to drastically reduce emissions by 2025. Last year, fossil fuel emissions remained at unprecedented levels, primarily responsible for the high temperatures. While natural phenomena such as the El Niño weather pattern contributed somewhat, experts assert that the overwhelming factor remains greenhouse gas emissions.

The past decade has recorded the warmest years in history, with 2024’s unprecedented warming conditions resulting in extreme weather patterns across various regions. Areas such as West Africa experienced intense heat; South America faced prolonged droughts; and North America and South Asia encountered powerful tropical storms—all intensified by climate change.

The 1.5°C target has gained significance in global discussions surrounding climate change, as it is viewed as crucial for the survival of the most vulnerable nations. The potential risks associated with exceeding this limit include intensified heat waves, rising sea levels, and severe biodiversity loss. The current trajectory indicates the world could cross the long-term 1.5°C threshold by the early 2030s.

Despite uncertainties regarding the predicted timing for crossing the 1.5°C mark, experts stress that every fraction of a degree matters. Scientists, including Zeke Hausfather from Berkeley Earth, emphasize that each increment in temperature exacerbates the likelihood of experiencing extreme climate impacts. The year 2024 not only marked an increase in air temperatures but also saw record highs in sea surface temperatures and atmospheric moisture content.

Various factors are contributing to the recent temperature spikes, including a noticeable reduction in low-level cloud cover, which traditionally helps cool the planet, coupled with lingering oceanic heat from the earlier El Niño. This phenomenon raises critical questions about whether the heightened warming is a persistent change linked to human activities or merely a natural fluctuation.

Despite the sobering figures, experts maintain that immediate global action remains pivotal. Dr. Hausfather highlights the importance of reducing greenhouse gas emissions, explaining that even if surpassing 1.5°C becomes inevitable, there are still opportunities to limit warming to levels around 1.6°C to 1.8°C within this century.

In conclusion, the 2024 climate data serves as a crucial wake-up call, emphasizing the necessity for collective efforts to mitigate climate change impacts as the world approaches an unprecedented climatic threshold.
