In the Sixth Assessment Report (AR6)* of the IPCC, which comprises the contributions of three Working Groups: Working Group 1 (the physical science basis); Working Group 2 (impacts, adaptation, and vulnerability); and Working Group 3 (mitigation), extremes including temperature extremes, heavy precipitation, pluvial floods, river floods, droughts, and storms are highlighted as main Climatic Impact Drivers (CIDs) that affect an element of society or ecosystems. These extremes are mentioned in the Working Group 1 Report to show the science of how and why the climate has changed.
In the Working Group 2 Report, research on the impacts of extremes (e.g., storms and floods) has evolved to include not only the assessment of impacts on the ecosystems and biodiversity but also the assessment of impacts on humans and their diverse societies, cultures, and settlements as well as social changes in population and economies.

Objectives of the Webinar Series

In view of the findings of AR6, the Advanced Study of Climate Change Projection (SENTAN), which comprises a number of research institutes in Asia and the Pacific, aims to achieve the integration of hazard models focusing on storm-and-flood hazards and water resources. In particular, it aims to develop a climate change impact projection model of extreme weather events (e.g., storms and floods) that is downscaled to Japan and Asia-Pacific region. This study will assess the effects of extreme weather events and analyze the changes of hazards with rising temperature, as downscaled to Japan and Asia-Pacific region.
Against this backdrop, the SENTAN project is organizing a series of webinars that will serve as venue to:

• present the framework of hazard-related weather information (developed by SENTAN) to be applied to climate change adaptation
• share the products of climate change projections and improve climate change literacy among DRR practitioners, researchers, and engineers.
