The Copernicus climate service reports that 2024 is the first year to show global temperatures exceeding 1.5C above pre-industrial levels, highlighting a concerning trend towards more severe climate impacts.
2024 Signals a Worrying Milestone in Global Warming Trends
2024 Signals a Worrying Milestone in Global Warming Trends
New data reveals 2024 has surpassed the 1.5C warming threshold, with implications for climate action and extreme weather.
The planet has reached a concerning juncture, with new data from the European Copernicus climate service indicating that 2024 marks the first calendar year to exceed the symbolic global warming threshold of 1.5C above pre-industrial levels. Although this milestone doesn't signify an official breach of the long-term average target agreed upon in the 2015 Paris Agreement, it underscores the escalating influence of greenhouse gas emissions on global temperatures.
UN Secretary-General António Guterres labeled the recent record temperatures as "climate breakdown," urging immediate actions to curtail emissions starting in 2025. According to Copernicus, average temperatures for 2024 have surged to approximately 1.6C above the pre-industrial baseline, making it the hottest year on record and surpassing the previous record set in 2023 by over 0.1C. This alarming trend indicates that the last decade has produced the ten highest temperatures recorded globally.
While experts anticipate corroborative temperature data from the Met Office and NASA later this week, early reports emphasize that the prevalent cause of the drastic temperature rise remains humanity’s emissions of planet-warming gases, despite the minor influences of weather phenomena like El Niño.
The 1.5C threshold has become emblematic in global climate negotiations, especially for the most vulnerable countries that associate it with their very survival. A pivotal 2018 UN report articulated the increased risks associated with 2C warming compared to 1.5C, indicating severe consequences such as exacerbated heatwaves, rising sea levels, and biodiversity loss.
Forecasts currently suggest that, if trends continue, the world may surpass the 1.5C long-term warming threshold by the early 2030s, an event that could have significant political ramifications but does not necessarily equate to a complete failure in climate efforts. Scientists stress that every fraction of a degree in warming significantly aggravates climate impacts, highlighting that the consequences of rising temperatures will intensify progressively.
In addition to record-breaking air temperatures in 2024, corresponding increases in sea surface temperatures and atmospheric moisture levels have also been documented. These unprecedented records have raised concerns around the pace of climate change, with various theories positing that we may be observing an acceleration in warming due to human activities, as well as natural variability.
Experts suggest that while the situation is serious, there remains control over future climate outcomes through significant reductions in emissions. Even if we approach a 1.6C target, it remains crucial to limit further warming, as the potential consequences of allowing temperatures to escalate to 3C or beyond could have dire outcomes for the planet and humanity alike.
