2024 has been confirmed as the hottest year on record, with climate scientists citing increasing greenhouse gas emissions as the primary driver. This has led to extreme weather events, including deadly hurricanes and heat waves, stressing the urgent need to mitigate climate change effects as nations approach the critical 1.5 degrees Celsius threshold outlined in the Paris Agreement.
Climate science authorities from the U.S., U.K., Europe, and Japan confirmed that 2024 is established as the hottest year on record, surpassing the previous year’s high temperatures due to escalating greenhouse gas concentrations. The report from the Copernicus Climate Change Service highlighted not only record average global temperatures but also unprecedented sea surface temperatures and atmospheric water vapor levels. As a consequence, milder heat waves and severe rainfall events have inflicted significant hardship on multiple populations around the globe.
Samantha Burgess, Deputy Director of C3S, stated, “These high global temperatures, coupled with record global atmospheric water vapor levels in 2024, meant unprecedented heat waves and heavy rainfall events, causing misery for millions of people.” In a related press conference, Gavin Schmidt, Director of NASA Goddard Institute for Space Studies, asserted that the link between anthropogenic warming and extreme weather phenomena has become increasingly evident, as such events grow more frequent.
NASA and NOAA scientists identified major weather extremities for 2024, such as Hurricane Helene, which resulted in over 230 fatalities across seven U.S. states, along with severe flooding in Spain, annual droughts affecting South America, and an early heat wave in Mexico. NOAA’s Russell Vose remarked that while extreme weather is on the rise, it is affected by other situational factors, including natural climate variability and human settlement patterns in vulnerable areas.
Factors influencing the year’s warming trend included the El Niño oceanic cycle and reduced cloud cover, intensifying sunlight exposure on the Earth’s surface. Nevertheless, experts assert that greenhouse gas emissions from fossil fuel combustion remain the principal compounding factor of rising temperatures. Gavin Schmidt noted that the overarching trend of increased global temperatures is unmistakable, while Samantha Burgess pointed out that every year within the last decade ranks among the top ten hottest on record.
Last year’s heat marked a brief transgression beyond the critical 1.5 degrees Celsius elevation above preindustrial temperatures—a significant threshold agreed upon by nations in the Paris Climate Agreement. Burgess acknowledged the troubling reality of consistently high average temperatures, observing that the combined figures for the last two years have already exceeded the 1.5 degrees Celsius level.
Moreover, U.S. organizations, alongside NASA and NOAA, have noted that warming trends are approaching the consensus 1.5-degree mark set forth in the Agreement. Climate scientists caution that the Paris Agreement’s temperature target symbolizes the broader climate impact associated with this level of warming. University of Pennsylvania scientist Michael E. Mann expressed concern that the current trajectory would propel temperature increases surpassing 1.5 degrees within a decade unless greenhouse gas emissions are curtailed. He emphasized that the focus ought to be on limiting overall temperature increases rather than fixating solely on the 1.5-degree threshold.
In light of these developments, devastating wildfires have engulfed Southern California, exemplifying the unfortunate outcomes of hastily rising temperatures. Mann concluded, “We can already see the devastating consequences of the warming we’ve already experienced, in the form of the apocalyptic wildfires currently ravaging Southern California.”
This article examines the unprecedented temperature rise recorded in 2024, particularly emphasizing the role of human-driven climate change and greenhouse gas emissions. It discusses how global scientific agencies have highlighted extreme weather events and changing climatic patterns that are directly related to increasing global temperatures. The context of the Paris Agreement sets a crucial backdrop, detailing the implications of temperature thresholds and the urgency surrounding global climate actions.
In summary, the year 2024 has solidified its place as the hottest on record, driven largely by human-induced greenhouse gas emissions. The resulting extreme weather events, such as hurricanes, floods, and heat waves, underscore the urgent need for global action to mitigate climate impacts. Furthermore, the approaching limits set forth in the Paris Agreement signal an imperative for nations to pursue aggressive climate strategies to avert further environmental degradation and human suffering.
