Over two dozen climate-fueled extreme weather events killed at least 3,700 people worldwide and displaced millions in 2024, according to a joint report by World Weather Attribution (WWA) and Climate Central.
In a sobering revelation, a joint report by World Weather Attribution (WWA) and Climate Central highlighted that human-induced climate change caused at least 3,700 deaths globally in 2024. Beyond the fatalities, the world experienced 41 additional days of dangerously high temperatures, with small island nations and developing countries bearing the brunt.
These findings underline the accelerating impact of climate change, as rising global temperatures fueled extreme weather events, from heatwaves to catastrophic storms and floods.
RELEVANT SUSTAINABLE GOALS
Record-Breaking Weather Events
The year 2024 was marked by unprecedented global temperatures, resulting in record-breaking rainfall and prolonged droughts. According to the report, 15 of the 16 floods studied were intensified by increased rainfall directly linked to climate change.
In stark contrast, regions like the Amazon rainforest and Pantanal wetlands suffered from severe droughts and wildfires, leading to catastrophic biodiversity losses. These dual extremes underscore the widening chasm in global climate impacts—while some regions drown, others burn.
While the report cites 3,700 deaths directly attributable to extreme weather events studied, the actual toll is likely far higher. “The real number could reach tens or even hundreds of thousands,” the report warned, as only a fraction of the most impactful events were analyzed.
Small island developing states and low-income nations were disproportionately affected, enduring not only more dangerous heat days but also heightened vulnerability due to limited resources for adaptation and resilience.
“This exceptional year of extreme weather shows how dangerous life has already become with 1.3°C of human-induced warming, and highlights the urgency of moving away from planet-heating fossil fuels as quickly as possible,” said the two organizations, which examined 26 destructive weather events that occurred in 2024—a fraction of the hundreds that took place globally this year.
According to WWA and Climate Central, the 26 events, ranging from Hurricane Helene in the United States to the typhoon that struck the Philippines, China, and Taiwan, resulted in nearly 4,000 fatalities.
Urgent Need for Action
WWA and Climate Central issued a clarion call for action:
- Faster Transition from Fossil Fuels: Phasing out coal, oil, and natural gas remains critical to mitigating global temperature rise.
- Increased Funding for Developing Nations: Developing countries, often at the frontline of climate impacts, require financial support to build resilience and recover from disasters.
- Improved Early Warning Systems: Advanced technologies to forecast extreme weather events can help save lives by providing communities with adequate time to prepare.
- Direct Heat Mortality Reporting: Real-time data on heat-related deaths is essential for accurate impact assessment and targeted interventions.
Dr. Friederike Otto, lead of WWA and a senior lecturer in climate science at Imperial College London, emphasized, “We possess the knowledge and technology to transition from fossil fuels to renewable energy sources, reduce demand, and halt deforestation. The time to act is now.”
A Year of Stark Lessons
As 2024 draws to a close, it stands as a harrowing testament to the escalating climate crisis. The report’s findings, including the death toll and biodiversity losses, illustrate the growing cost of inaction. If global warming exceeds 1.5°C above pre-industrial levels—a threshold scientists warn could have catastrophic consequences—the frequency and intensity of extreme weather events will only worsen.
The road to a sustainable future demands immediate, collective action. Governments, industries, and individuals must work together to decarbonize economies, protect vulnerable populations, and invest in adaptation measures.
The lessons from 2024 are stark: climate change is not a distant threat but an unfolding crisis. Without decisive action, the world risks deeper losses, not just in numbers but in the very ecosystems that sustain life.
