Copernicus Climate Report 2024: Key Findings and Impacts
Summary
Overview of 2024 Highlights
In 2024, global temperatures hit record highs, marking the first calendar year to exceed 1.5°C above pre‑industrial levels. Europe experienced its warmest year on record, coupled with devastating floods, heatwaves, storms and wildfires. Sea surface temperatures and atmospheric moisture reached new peaks, intensifying extreme weather and stressing ecosystems worldwide.
Global Climate Highlights
1. Temperature Anomalies
- 2024 was the warmest year on record globally, with average surface air temperatures 1.51–1.56°C above 1850–1900.
- 91% of the globe saw temperatures above the 1991–2020 average; over half of land areas were >1°C above that baseline.
- About 75% of days in 2024 recorded temperatures >1.5°C above pre‑industrial levels.
2. Heat Stress
- 44% of Earth's land experienced at least “strong heat stress” on 10 July—the highest area ever recorded.
- 61% of land areas had more days than average with “strong heat stress” (>32°C feels‑like).
3. Sea Surface Temperature
- Annual extra‑polar sea surface temperature reached a record 20.87°C—0.51°C above the 1991–2020 average.
- SST records were set from January to June, with March peaking at 21.07°C.
4. Atmospheric Water Vapour
- Total column water vapour was 4.9% above the 1991–2020 average—the highest in at least 33 years.
- This moisture boost fuels more intense rainfall and storms worldwide.
European State of the Climate
1. Temperature Records
- Europe’s average temperature reached 10.69°C—0.28°C above the previous record (2020).
- Spring and summer were the warmest ever, at +1.50°C and +1.54°C above the 1991–2020 average.
2. Extreme Weather Events
- Floods affected over 30% of Europe’s river network, causing 335 deaths and impacting 413 000 people.
- Storm “Boris” brought record rain across Central Europe; Portugal’s wildfires burned 110 000 ha.
- Southeastern Europe saw a 13‑day heatwave—the longest on record.
3. Economic and Human Impacts
- Floods and storms in 2024 caused over €18 billion in economic losses.
- Wildfires and heat stress strained healthcare and agriculture.

Conclusion and Opinion
Why This Matters
The 2024 Copernicus reports demonstrate that human‑driven warming is now exceeding critical thresholds, with cascading impacts from heat stress to floods and wildfires. These data underline the urgent need for rapid emission cuts and investment in adaptation measures—from heat‑resilient infrastructure to advanced early‑warning systems. Failing to act risks locking in even more severe weather extremes, higher economic costs and deeper social inequities.
believe this report marks a clear turning point: crossing the 1.5°C threshold is not just symbolic but ushers in more frequent and severe extremes, as seen in Europe’s deadly floods and record heat stress worldwide. The unprecedented sea surface warming and water‑vapor increase amplify storm intensity and flood risks, while heatwaves threaten health and agriculture. My view is grounded in the data: without swift mitigation (phasing out fossil fuels) and robust adaptation (urban greening, cooling centers, flood defenses), we will face escalating costs and human suffering. The Copernicus reports make one thing clear—time for incremental steps is over; only decisive, large‑scale action can steer us away from the worst outcomes.
