10 years since the Paris Agreement – statements, data and visuals
Ten years since the momentous Paris Agreement was signed at COP21, the world stands at a pivotal crossroads – and global climate and atmospheric data tell the story. 2024 saw atmospheric concentrations of carbon dioxide and methane reach new record levels; it was our warmest year on record, exceeding 1.5oC above pre-industrial levels; and a large number of extreme events were recorded across the globe, including heatwaves, floods, droughts and wildfires.
As COP30 convenes in Belém, the Copernicus Climate Change Service (C3S) and Copernicus Atmosphere Monitoring Service (CAMS) have compiled data that reveal the climate and atmospheric signals that have defined this decisive decade.
The data produced by C3S and CAMS act as both a collective memory of our planet and as an indicator of where our climate could be headed. This enables governments, industries and communities to make targeted, science-driven choices – from anticipating the impacts of heat extremes and droughts in order to strengthen resilience, to assessing solar and wind intensity to plan renewable energy deployment. This open-access science-based data ensures that the decisions made in Belém can be grounded in the reality of our planet’s systems - measurable, traceable, and quality-assured.
Laurence Rouil, Director of the Copernicus Atmosphere Monitoring Service, says:“From air pollutants to greenhouse gas concentrations, our atmosphere is perhaps the most direct and immediate indicator of every action we take. Over the past decade, CO2concentrations have risen over 5%, reaching their highest annual levels ever recorded. CAMS monitor their evolution and track their sources. Aside fossil fuel emissions which accounted for almost 75% of total carbon emissions in 2024, wildfires already released more than 1300 megatonnes of carbon in 2025, and huge amounts of particulate matter that degrades air quality and have harmful impacts on human health. This 10-year benchmark is not only a milestone, but also a mirror – that reflects how progress over the last decade measures up to the ambitions of the Paris Agreement. The last decade has seen significant change, and the next decade will be decisive. But knowledge is power; and delegates at COP30 have more knowledge, data and understanding of our atmosphere than ever before – we encourage them to use this to turn ambition into action.”
Carlo Buontempo, Director of the Copernicus Climate Change Service, says:“A decade after the Paris Agreement, the world is hotter than ever – every year since has ranked among the 10 warmest on record. It’s now evident that the climate is shifting at a pace humanity has never experienced. But we do have one superpower in our efforts to tackle climate change – a rich supply of timely scientific data, information and knowledge, all free open and available to everyone without restrictions. It’s this information that gives policy makers the power to respond with confidence and clarity in the face of rapid change. It is this evidence that must guide the delegates at COP30. The choices we make today will shape the planet’s future, forever. We must ensure those choices are grounded in facts.”
