IPCC co-chair Panmao Zhai answers three quick questions on CORDEX/IPCC
- Why is CORDEX and the work carried out within the CORDEX framework important from an IPCC perspective?
CORDEX aims to develop and provide detailed, regional climate information necessary for vulnerability, impact and adaptation studies at local and regional levels. The aims of CORDEX fit perfectly for IPCC AR6, under the demands of governments for increased policy-relevant regional downscaled information, to fill the noted knowledge gaps in climate change hazards, risks and adaptation at the national, regional or even local levels.
- Could you give some examples?
To address and enhance the treatment of regional climate change issues, the structure of IPCC WGI AR6 has been designed to allow a detailed and comprehensive assessment of regional and sectoral-relevant climate information. Among 12 scoped chapters, we have three dedicated chapters linking global to regional climate change, weather and climate extremes and climate information for regional impact and risk assessment,. We also have an Altlas providing regional climate change information visually.
CORDEX supports IPCC assessment on coordinated regional climate change and extreme information. A comprehensive assessment of multiple sources of regional climate information, including downscaling methodologies is in great need in WGI AR6 report. Thus, outcomes from CORDEX, will be huge support to improve regional scale information not only on historical simulations but also on future climate change.
- What do you hope from the conference – what will it contribute to?
This main focus of the International Conference on Regional Climate (ICRC)- CORDEX 2019 including benefits of downscaling; further development of earth system models; the human factor, impacts and applications and knowledge exchange. Many of these can directly contribute to IPCC AR6, especially on downscaling impact and application, and updated knowledge exchange for various regions. Some others such as further development of earth system models can contribute to future IPCC activities. I hope the outcome of this conference can be published as soon as possible to support AR6 reports for WGI and WGII.
