【3▪23世界气象日】2021年世界气象日主题：海洋、我们的气候和天气！

近日，联合国专门机构世界气象组织（WMO）公布2021年世界气象日主题：海洋、我们的气候和天气！

World Meteorological Day 2021 - The ocean, our climate and weather

Covering some 70% of the Earth’s surface, the ocean is a major driver of the world’s weather and climate. It also plays a central role in climate change. The ocean is also a major driver of the global economy, carrying more than 90% of world trade and sustaining the 40% of humanity that lives within 100 km of the coast. Recognizing this, National Meteorological and Hydrological Services and researchers regularly monitor the ocean and how it is changing, modeling how it affects the atmosphere and delivering a wide variety of marine services, including supporting coastal management and Safety of Life at Sea. Today, the growing impacts of climate change are making ocean observations, research and services more critical than ever before.

The World Meteorological Day theme - The ocean, our climate and weather – celebrates WMO’s focus in connecting the ocean, climate and weather within the Earth System. It also marks the launch of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030). The Decade galvanizes efforts to gather ocean science – through innovative and transformative ideas - as the basis of information to support sustainable development. WMO, as the United Nations specialized agency for climate, weather and water, strives to support understanding the inextricable link between ocean, climate and weather. This helps us understand the world in which we live, including the impacts of climate change, and to help Members to strengthen their ability to keep lives and property safe – reducing the risk of disaster – and to maintain viable economies.
