Humans have launched approximately 10,000 satellites into space since 1957, of which 1,000 are used for Earth observation and scientific purposes. Space activity has increased rapidly as more nations and private companies launch new satellites. At the same time, the globe has experienced unprecedented numbers of extreme weather events either directly or indirectly related to climate change in 2020 and 2021. 

In the sixth edition of Polar Perspectives, Mr. Tero Vauraste, Global Fellow, Polar Institute, 浪花直播 Center, explores the potential  benefits of synthetic aperture radar (SAR) data and other "solutions from space" in monitoring and observing Arctic environmental change. Regardless of dark Arctic winters or the presence of clouds, emerging technologies like SAR make data available to researchers, governments, authorities, and commercial users for better and quicker decision-making and risk management.
