Australia-based Lead and Coordinating Lead Authors for the Seventh Assessment Report.
Statements from nine selected Lead and Coordinating Lead Authors
As Coordinating Lead Author for Chapter 1 of the WGI report, I will be working with my fellow Lead Authors to ensure the Chapter provides the necessary background and framing for the rest of the WGI report. This will be a significant undertaking that will require close collaboration with the authors from the other chapters. Chapter 1 will " set the tone " for the rest of the report, and among other things, provide the overall framework and clarify key concepts, helping readers navigate the rest of the report.
In my own research, my main focus is on delivering regional climate projections at an unprecedented 4km resolution over Western Australia. Given that southwest WA is often referred to as the canary in the coalmine of climate change, the hope is that some of this work will inform the regional chapters in the upcoming AR7 report.
I look forward to working with an incredible team of climate scientists from around the world. There will no doubt be a lot of discussion along the way. Being chosen to be part of the team that delivers the AR7 report is a great honour.
Jatin Kala, WGI, Chapter 1: Framing, methods and knowledge sources
Our chapter will be working on large-scale observed changes in global climate and their attribution. In AR6, I led the assessment of observed global temperature changes( surface and upper air) and ENSO, but the exact roles this time are yet to be decided, and I may well be dealing with different variables. As lead of the WMO Task Team on assessing current warming levels, I form a bridge between operational climate monitoring and the longer-term assessments of IPCC; assessing current warming levels will probably be a particularly high-profile part of AR7 as warming approaches 1.5 ° C.
