Essential Climate Variables

Essential Climate Variables (ECVs) are specific measurements used to monitor Earth's climate and understand changes over time. They include key data like temperature, rainfall, sea level, ice cover, and greenhouse gases. These variables help scientists track trends, detect climate change, and improve climate models. By focusing on these critical indicators, ECVs provide a consistent and reliable way to assess the health of our planet’s climate system. In simple terms, they are the most important pieces of climate data that tell us how our environment is evolving.
