At the stroke of midnight on Dec. 31, 2024, Earth wrapped up its hottest year on record, surpassing the previous record set in 2023. The global temperatures last year soared past a critical milestone, signaling the urgent need for nations to address the escalating threat of climate change.
Unprecedented Heat Waves and Natural Disasters
The scorching temperatures that dominated 2024 brought about a myriad of devastating consequences worldwide. From prolonged heat waves closing schools in Bangladesh and India to ocean warming fueling powerful hurricanes and cyclones, the impact was undeniable. Los Angeles faced historic wildfires fueled by searing summer and fall conditions.
Carlo Buontempo, from the Copernicus Climate Change Service, underscored the unprecedented challenges posed by this new climate paradigm: “We are facing a very new climate and new challenges, challenges that our society is not prepared for.”
Crossing A Dangerous Threshold
In a disheartening turn of events, 2024 marked the first time global temperatures surpassed 1.5 degrees Celsius above pre-industrial levels—a threshold nations had endeavored to avoid as per the Paris agreement’s targets set in 2015.
Despite substantial investments in clean-energy technologies globally, carbon dioxide emissions hit an all-time high in 2024 with no signs of abating. Experts suggest that limiting warming to even 1.6 degrees Celsius would require monumental efforts beyond current political feasibility.
The Missed Opportunities
Reflecting on what could have been done differently to avert this crisis, experts point out missed opportunities for emission reductions over the years. Starting significant emission cuts as far back as 2005 could have paved a smoother path towards limiting warming to safer levels.
David Victor of UC San Diego lamented how neglect led humanity astray from the trajectory needed to contain warming within safe limits: “It was guaranteed we’d get to this point where the gap between reality and the trajectory we needed for 1.5 degrees was so big it was ridiculous.”
Rethinking Goals Amidst Growing Concerns
As nations grapple with surpassing critical thresholds sooner than anticipated, questions loom over whether aspiring for only limiting warming to 1.5 degrees remains feasible or realistic given current emission trends.
Costa Samaras likened these goals to health targets—setting aspirations based on what’s best rather than what seems immediately achievable: “If we were going to say ‘1.75 is more likely,’ it gives people a false sense of assurance that 1.5 was not that important… It’s hugely important.”
A Call for Urgent Action Despite Challenges
While achieving stringent targets may seem daunting amidst escalating emissions and political complexities between developed and developing nations, there’s unanimous agreement among experts on one thing—urgent action is imperative.
Inger Andersen emphasized relentless efforts towards zero emissions despite potential overshooting of temperature limits: “Even if world overshoots…we must keep striving” towards emission neutrality at earliest possibility.
With uncertainties looming over future climate negotiations and goal revisions looming large amidst growing political pressures globally—experts like Dr.Victor foresee heated discussions ahead which could shape our approach towards tackling climate change moving forward.
