Jongsoo Shin

I study why the planet doesn't simply bounce back once we stop emitting carbon: how oceans and ice hold on to decades of warming long after the atmosphere moves on. That question has taken me from Seoul to Woods Hole and back. I build ocean models and work on the slow physics of climate change at Seoul National University.

Research interests

Hysteresis loop: the climate response on the ramp-down path does not return to its starting value CO₂ concentration Climate response irreversible ramp-up ramp-down
Climate system reversibility and hysteresis How the ocean, land and atmosphere respond asymmetrically to rising versus falling CO₂.
MCOM in CESM2: independent one-dimensional ocean columns exchange heat and water with the atmosphere Atmosphere CESM2 1-D ocean columns (MCOM)
Earth system modeling and development Development of the Multi-Column Ocean Model (MCOM) within the CESM2 framework.
CO₂ emissions fall to net zero or net negative; heatwaves, extreme rain and drought are projected along each pathway CO₂ emissions 0 net zero net negative Heatwaves Extreme rain Drought
Net-zero and extreme event projection Climate change and extreme event risk under net-zero and negative emission scenarios.
