Data and Scenario Support for Impact and Climate Analysis (TGICA) Services

0
The Task Group on Data and Scenario Support for Impact and Climate Analysis (TGICA) facilitates distribution and application of climate change related data and scenarios. The conduct of TGICA is governed by its mandate.TGICA oversees a Data Distribution Centre (DDC) which provides data sets, scenarios of climate change and other environmental and socio-economic conditions, and other materials (e.g. technical guidelines on the use of scenarios and factsheets offering clarifying explanations/concise guidance on topical issues).

TGICA also contributes to building capacity in the use of data and scenarios for climate-related research in developing and transition-economy regions and countries. TGICA also convenes expert meetings on an as-needed basis and the DDC links to relevant data sets and information held outside the DDC, such as outputs produced from the new community-led process of scenario development to support climate change research.
 
Since the TGICA was established in 1996, a great deal has changed regarding needs and services for data and scenarios. Most significantly, the community of users has evolved from a relatively small group of researchers focusing on global- and regional-scale modelling of the impacts of climate change, to a large and diverse set of actors worldwide, including national, state/provincial, and local entities, business and industry, non-governmental organizations, and community groups, including participants in the UNFCCC Nairobi Work Programme on impacts, vulnerability and adaptation to climate change. This more diverse group of users has a far more varied set of data and scenario needs, including data products more appropriate to settings with limited computational, communications, and research capacity. The process for preparation of scenarios has also changed, and has become a more open, interdisciplinary process with a larger number of interactions across the climate modelling, impacts/adaptation/vulnerability, and integrated assessment modelling communities. These changes provide new challenges and opportunities for the TGICA.
 
TGICA Membership was refreshed in the summer of 2010 (see table below). The first meeting of the reappointed Task Group (TGICA-16) was held at the National Center for Atmospheric Research in Boulder, Colorado, USA on 4-6 August 2010. Timothy Carter (Finland) and Bruce Hewitson (South Africa) were appointed in May 2011 to serve as Interim TGICA Co-Chairs for a period of two years, with Ms Rachel Warren (United Kingdom) appointed as Co-Chair elect. A second full meeting, TGICA-17, was held at Jasper Ridge Biological Preserve, Palo Alto, California, USA on 6-8 February 2012. A third meeting,TGICA-18, was held on 18-20 September 2012 in St Petersburg, Russian Federation and a fourth, TGICA-19, was held on 14-16 May 2013 in Jeju, Republic of Korea.
 
Further information about TGICA activities and developments can be found in Progress Reports submitted to Sessions of the IPCC. As of April 2013, three Progress Reports of the newly constituted Task Group are available for download: IPCC-XXXV/Doc. 22 (June 2012), IPCC-XXXIV/Doc.13 (November 2011), and IPCC-XXXIII/Doc. 19 (May 2011). In addition, a presentation (pdf) about TGICA and its current activities was provided by the interim TGICA Co-Chairs at the 35th Session of the IPCC (6-9 June 2012, Geneva).
