2024: the Hottest year on Record and a Wake-Up Call for Climate Action
The world Meteorological Organization (WMO) has confirmed that 2024 was the hottest year on record, surpassing the symbolic 1.5°C global warming threshold set by the Paris Climate Agreement.This milestone, long feared by climate scientists, underscores the urgent need for global action to mitigate the escalating impacts of climate change.“We have seen remarkable land and sea surface temperatures, extraordinary ocean heat, accompanied by very extreme weather affecting many countries around the world, destroying lives, livelihoods, hopes and dreams,” said Clare Nullis, spokesperson for the WMO. “It was an extraordinary year.”
Breaking the 1.5°C Barrier
Four of the six international datasets analyzed by the WMO indicated a global average temperature increase of more than 1.5°C in 2024, with an average rise of 1.55°C compared to pre-industrial levels (1850-1900). While two datasets did not exceed this threshold, the findings highlight the precarious state of the planet’s climate.
The 1.5°C limit is a critical benchmark established by the paris Agreement to prevent the most catastrophic effects of climate change. However, the WMO emphasized that the agreement’s long-term goals are measured over decades, not individual years. “The Paris Agreement is not dead yet but in great danger,” the agency stated.
A Decade of Record Temperatures
WMO Secretary-General Celeste Saulo described 2024 as the culmination of a decade-long trend of rising temperatures. “Climate history is unfolding before our eyes,” she said. “We have not just had one or two record years, but a whole series of ten years.”
The impacts of this warming are already devastating. From deadly wildfires in Los Angeles to the retreat of sea ice glaciers,the effects of climate change are being felt worldwide. “Each fraction of a degree of warming is important,” Saulo stressed. “Whether it is indeed warming below or above 1.5°C, each additional increase in global warming increases the impact on our lives, our economies, and our planet.”
A Call to Action
United Nations Secretary-General António Guterres called the WMO’s findings “new evidence of global warming” and urged governments to implement new national climate action plans in 2025. “Just because some years exceed the 1.5°C limit does not mean the long-term goal has been achieved,” Guterres said. “this means we have to fight even harder to stay on track. The blazing temperatures of 2024 demand cutting-edge climate action in 2025.”
Guterres also emphasized the need to support vulnerable communities grappling with the devastating effects of climate change. “There is still time to avoid the worst climate catastrophe,” he said. “But leaders must act now.”
Ocean Warming: A Critical Indicator
A separate scientific study highlighted by the WMO revealed that ocean warming played a important role in 2024’s record temperatures. “The ocean is the hottest on record by man, not only at the surface but also in the upper 2,000 meters,” the agency reported.
The study, published in the journal Advances in Atmospheric Sciences, found that the ocean’s heat content increased by 16 zettajoules (ZJ) from 2023 to 2024—equivalent to 16,000 billion billion joules. This trend has persisted over the past five years, with ocean heat content rising by 15 to 20 ZJ annually, despite the influence of natural climate cycles like La Niña and El Niño.
“About 90% of excess heat from global warming is stored in the oceans,” the WMO noted, “making ocean heat content a critical indicator of climate change.”

2024: The Hottest Year on Record and a Wake-Up call for Climate Action
the world Meteorological Organization (WMO) has confirmed that 2024 was the hottest year on record, surpassing the symbolic 1.5°C global warming threshold set by the Paris Climate Agreement. This milestone underscores the urgent need for global action to mitigate the escalating impacts of climate change. To delve deeper into the implications of these findings, we sat down with Dr. Elena Martinez, a leading climate scientist and oceanographer, to discuss the record-breaking temperatures, rising ocean heat content, and the path forward for climate action.
The 1.5°C Threshold: What Does It Mean for the Planet?
Senior Editor: Dr. Martinez, the WMO reported that 2024 exceeded the 1.5°C warming threshold.Can you explain what this means for the planet and why it’s such a critical benchmark?
Dr. Martinez: Absolutely. The 1.5°C threshold is a key target set by the Paris Agreement to avoid the most catastrophic impacts of climate change. When we talk about exceeding this threshold, even temporarily, it’s a stark reminder of how close we are to tipping points that could lead to irreversible damage—like the collapse of ice sheets, loss of coral reefs, and more frequent extreme weather events. While the WMO clarified that this is a single-year anomaly and not a long-term average, it’s still a wake-up call. Every fraction of a degree matters, and we’re seeing the consequences play out in real time.
ocean Heat Content: A Critical Indicator of Climate Change
Senior editor: The WMO also highlighted a significant increase in ocean heat content, with 16 zettajoules added from 2023 to 2024. Why is this such an critically important metric, and what does it tell us about the state of our climate?
Dr. martinez: The oceans are the Earth’s largest heat sink, absorbing about 90% of the excess heat from global warming. When we see a rise in ocean heat content, it’s a clear signal that the planet is warming. Over the past five years, we’ve observed an annual increase of 15 to 20 zettajoules, which is staggering. This heat doesn’t just disappear—it fuels stronger hurricanes, disrupts marine ecosystems, and contributes to sea level rise through thermal expansion.The fact that this trend persists despite natural climate cycles like La Niña and El Niño shows how dominant human-driven warming has become.
The Role of the Paris agreement: Is It still Achievable?
Senior Editor: the WMO stated that the Paris Agreement goals are “not dead yet but in great danger.” What’s your take on this? Is it still possible to limit warming to 1.5°C?
Dr. Martinez: It’s a tough question. The Paris Agreement is still within reach, but the window is closing rapidly. To stay below 1.5°C,global emissions need to peak by 2025 and decline by 43% by 2030. That’s an incredibly ambitious target, and current policies and commitments aren’t enough to get us there. However, I remain cautiously optimistic. We’ve seen significant progress in renewable energy adoption, and public awareness of climate issues has never been higher. What we need now is unprecedented political will and international cooperation to accelerate the transition to a low-carbon economy.
extreme Weather Events: A Glimpse into the Future?
Senior Editor: 2024 saw devastating wildfires, floods, and heatwaves. Are these events a preview of what’s to come if we don’t act decisively?
Dr. Martinez: Regrettably, yes. The extreme weather events we’re witnessing are consistent with what climate models have predicted for a warming world. Heatwaves are becoming more intense and prolonged,wildfires are burning larger areas,and heavy rainfall events are leading to catastrophic flooding. These impacts are not evenly distributed—vulnerable communities,notably in developing countries,are bearing the brunt of the damage. If we don’t act now, these events will only become more frequent and severe, with devastating consequences for ecosystems, economies, and human lives.
The Path Forward: What Needs to Happen Next?
Senior Editor: The WMO’s findings are a stark reminder of the urgency of climate action. What steps do governments, businesses, and individuals need to take to address this crisis?
Dr. Martinez: It’s going to take a multi-faceted approach. Governments must strengthen their climate policies, set more ambitious emissions reduction targets, and invest in renewable energy and climate resilience. Businesses have a critical role to play by adopting sustainable practices and transitioning to net-zero operations. And individuals can make a difference by reducing their carbon footprint, advocating for climate action, and supporting leaders who prioritize the habitat.
But perhaps most importantly, we need to recognize that climate change is not a distant threat—it’s happening now. The record-breaking temperatures of 2024 are a call to action. We have the tools and the knowledge to address this crisis, but we need to act with urgency and determination. The time to act is now.
Senior editor: Thank you, Dr. Martinez, for your insights. It’s clear that the stakes are high, but there’s still hope if we act decisively.
Dr. Martinez: Thank you. I beleive that together, we can rise to this challenge and create a more sustainable future for generations to come.
