With many issues emerging in this global era, which cannot be solved by one country, such as climate change and pandemics, it is more important than ever for international cooperation […]

Compound extreme events refer to the simultaneous occurrence of two or more extreme weather phenomena, such as superimposed drought, heatwave, and fire. These events often cause more significant impacts on […]

Rapidly increasing carbon dioxide (CO₂) emissions over recent decades, coupled with the potential for further increases in the coming decades, have driven global efforts to remove and sequester carbon to […]

 We focus on the use of probabilistic and ensemble machine learning (ML) methods to facilitate the modeling of Earth system processes. The techniques we consider range from generative ML models […]

 Since the initiation of the ‘Earth Simulator’ supercomputer at JAMSTEC in 2002, the JAMSTEC modeling groups have been conducting multi-scale climate simulations. In this presentation, we will focus on our […]

This presentation will look at some of the science underpinning multilateral environmental agreements – on climate change, ozone, biodiversity, and hazardous substances – and assess the impacts of these agreements […]

 In this seminar, I will introduce the different regional characteristics of the summer surface temperature trend in the Northern Hemisphere. Strong surface warming hotspots occur mainly over Europe and western […]

Marine heatwaves (MHWs), the prolonged extreme ocean warming events, occur not only at the ocean surface but also extensively in the global subsurface ocean. In the subsurface, as depths increase, […]

Climate models are plagued by long-standing biases. Increasing resolution to km-scales is not the solution, as recent massive ongoing efforts have shown. In contrast, supermodelling—an advanced physics-informed machine learning approach—can […]
