SMHI contributes to the IPCC AR5 on Climate Change

During 2013 and 2014 the Intergovernmental Panel for Climate Change concluded its fifth Assessment Report on Climate Change (AR5). Researchers and experts from SMHI have contributed to the report in many ways.

Researchers and experts from SMHI have contributed to the fifth assessment report in many ways; with results from research and climate modelling, with climate data, and in the review process. Markku Rummukainen, climate expert at SMHI, is one of the lead authors in Working Group 1 (WG1).

Until the end of 2013, the Swedish Environment Protection Agency acted as the national focal point for the IPCC in Sweden, led by Marianne Lilliesköld. Erik Kjellström, Head of the Rossby Centre at SMHI, provided expert scientific support to the Swedish delegation during the final discussions of the Summary of Policymakers for WG1– the Physical Science Basis.

From the start of 2014, SMHI took over as the national focal point for IPCC in Sweden. Climate researcher Lars Bärring of the Rossby Centre, together with Lena Lindström at the Core Services department at SMHI, serve as the national IPCC office, and represent Sweden in the negotiations of the Working Group 2 and 3 reports (March and April 2014), and the Synthesis report (October 2014).

Climate models on future climate

Rossby Centre, SMHI’s climate research unit, is working with the development of climate models and modelling applications for process studies and climate change results. Data from future climate scenarios, calculated with the global climate model EC-Earth, is part of the group’s contribution to the international CMIP5 data archive, which provided the base for the first part of the Fifth Assessment report.

Climate Change Adaptation

SMHI has been commissioned to create a national knowledge centre for climate change adaptation. The purpose is to collect updated knowledge about vulnerability and climate change adaptation. One important aspect is to provide case studies and thereby make it easier to practice adaptation at local and regional level. The national knowledge centre is responsible for (website in Swedish on climate change adaptation, with information about the effects of climate change, risk management, how an adaptation plan can be developed and examples of how climate change adaptation can be integrated into the daily work).

Short-lived Climate Pollutants, SLCP

SMHI has coordinated the Swedish work on SLCP since 2011 on behalf of the Ministry of the Environment. The IPCC AR5 WG3 report is focused on the mitigation of climate change, where SLCP are being considered for the first time.
