This was the beginning of the long-term research on global warming, which I have continued until now in collaborating with the staff members of Geophysical Fluid Dynamics Laboratory of NOAA. In the late 1960's, Kirk Bryan and I began to develop a general circulation model of the coupled atmosphere-ocean-land surface system, which eventually became a very powerful tool for simulating global warming. More recently, we have realized that a coupled model can successfully simulate many low frequency variabilities of climate. This has encouraged us to use a coupled model for exploring not only global warming but also unforced, natural variability of climate with seasonal to decadal time scales. The analysis of deep-sea cores indicates that the Earth's climate has fluctuated greatly during the geological past. Throughout my career, past climate changes have provided many exiting issues, which we have explored using climate models with various complexity. Recent Publications: Manabe, S., J. R. Knutson, R.
