In-Sik Kang’s career in climate science started about half a century ago, and it has been remarkable in many ways—scientifically, but also in that In-Sik has spent most of his life in a country that started from very little, in climate science and every other way, having been devastated by war right at the start of his life. In-Sik is a long-time global leader in climate modeling, climate variability, seasonal climate prediction and atmosphere-ocean interaction. He built a large and amazingly successful group over several decades as a professor at Seoul National University. At SNU, he and his students built an original atmosphere-ocean general circulation model, or climate model, one of very few University groups to do that in-house in the modern era where it tends to happen only in national labs, and they also turned this into a state-of-the-art seasonal prediction system. The many generations of students that he trained now fill academic and research positions in Korea, the US and elsewhere. Like almost no other scientist in the field, In-Sik has been a tireless organizer and builder of scientific collaboration and scientific institutions internationally. He has done this through service on many international committees and panels; through his long-time affiliation with the International Centre for Theoretical Physics in Trieste, Italy; and through his work as an advisor, formally and informally, to climate scientists in many developing countries. Having grown up in a poor country himself, In-Sik can relate to their struggles, but he is also keen to underline the importance of self-responsibility: "And then I ask them immediately, "Can you change your country? Can you change your institution? And can you change your professor? Of course, no, right? So that [means] you should change yourself.” Most recently he helped the founders of the Center of Excellence for Climate Change Research at the King Abdulaziz University in Saudi Arabia to get that center started. For all this work, in 2021 In-Sik was awarded the IMO prize, the highest award given by the World Meteorological Association. In-Sik’s family came from North Korea, but fled to the South just before his birth to escape communism and war. So In-Sik grew up in Busan, at the southern tip of South Korea, during a time when the country was poor to a degree that’s hard to grasp if you only know it from recent decades. But he got an education at SNU, the nation’s top University, became a weather forecaster in the military, and then, by a serendipitous connection, got admitted as a graduate student at Oregon State University in the US. He did so well there that he finished in just a little over 3 years, and got a postdoctoral position to work with Isaac Held at GFDL, despite not having published any papers yet. From there In-Sik got a faculty position back at SNU, and the rest is history. But In-Sik’s own story, as he’s the first to point out, runs parallel to, and in some ways exemplifies that of his country, as both rose from poverty and hardship to amazing, globally recognized success, through talent, intense hard work, and a profound belief in the importance of education.
