The CliC leadership is composed of many leading experts in the cryosphere and climate research fields who dedicate their time to international efforts. These include the CliC Co-Chairs, the Scientific Steering Group (SSG) members, the WCRP Joint Science Committee Liaisons, and Joint Planning Staff officer (in charge of CliC), the targeted activity, working group, forum and project leaders, the International Project Office and the CliC Fellows. This group comes together yearly at the CliC SSG meetings, and communicates intersessionally via email and online meetings.

CliC Scientific Steering Group

CliCSSG15 December2019 SanFranciscoA group of selected scientists - the CliC Scientific Steering Group (SSG) - has the overall responsibility for planning and guiding the CliC project. Its members are appointed by the Joint Scientific Committee (JSC) of the World Climate Research Programme, based on recommendations by the CliC SSG. The Chair (or Co-chairs) is responsible for recommending changes in SSG membership to the JSC. Initial membership is for four years and, as a rule, up to two extensions of two years each may be recommended for members. For co-chairs, a one year extension as a member is possible. The SSG usually meets once a year.


James Renwick (Co-Chair, 1/2017-12/2021, WCRP Joint Scientific Committee Liaison 1/2013-12/2016)

James RenwickI am a professor of physical geography at Victoria University of Wellington, New Zealand. My career has included a decade in research at the NZ Met. Service, and 20 years of climate research at NIWA. I am fascinated by the general circulation of the atmosphere – how the atmosphere transports energy and momentum and what it does to achieve this. In particular I am interested in how heating in the tropics is communicated to higher latitudes by the excitation of large-scale waves and how this affects the storm tracks, jet streams, and the location and frequency of long-lived ‘blocking’ anticyclones. In recent years I have developed an interest in Antarctic climate, especially the growth and decay of Antarctic sea ice. How does the atmospheric circulation (the wind) affect sea ice extent and how this can be tied back to tropical influences? Beyond these topics, I have a general background in atmospheric physics, plus mathematics and statistics and have broad interests most aspects of climate, from the distant past to the near future. This includes paleoclimate reconstruction, synoptic climatology, climate modelling, climate change, and the use of statistical and matrix techniques to analyse large data sets. I served as a lead author for the IPCC 4th and 5th Assessment Reports, in Working Group I (physical science) and am chair of the Royal Society of New Zealand Climate Expert Panel.
