Landmark report defines climate change in Austria

The Austrian Climate Change Assessment Report (AAR14), released today, is the first national-level climate report that mirrors the breadth and rigor of the Intergovernmental Panel on Climate Change (IPCC), examining the historical and future development of climate change, as well as the potential response and mitigation measures for the problem.

“Climate change is happening at the global level, but its effects will be different in every country,” said IIASA Deputy Director General Nebojsa Nakicenovic, who was the project leader. “It is vital that we understand how climate change will impact Austria, in order to embark on mitigation and adaptation strategies at a national level.”

Over 240 scientists from over 50 institutions contributed data and findings to the report, and the review process included 71 external reviewers, over 2900 comments and questions, and 13 review editors who ensured that all comments were taken into consideration.

Key findings of the report include:

• Since 1880, average temperature in Austria has risen by nearly 2°C, compared with a global average increase of 0.85°C. The report projects that by 2050, the average temperature in Austria will likely increase by approximately 1.4°C compared to current temperatures.

• Extremely hot days are expected to become more frequent in summer, while very cold days will become rarer in winter.

• Snow cover duration and glacier extent have decreased significantly in recent decades, and this trend is likely to continue.

• Precipitation patterns are likely to change, but with significant regional differences. On average, the report projects an increase in precipitation in winter months, and a decrease in summer months.

• The risk of natural disasters including landslides and rockfalls, as well as forest fires, is project to increase as precipitation patterns change and the temperature increases.

The report also suggests that current efforts by the Austrian government to promote energy efficiency and renewable energy sources alone will not be adequate to meet the expected contribution of the country to achieve the global goal of limiting climate change to an average 2°C rise over pre-industrial levels.

Nakicenovic says, “Mitigation and adaptation strategies for climate change in Austria need to involve all sectors and stakeholders to achieve the ambitious goal consistent with a 2 degree stabilization in average global surface temperature.”

IIASA and the APCC
IIASA’s role in the AAR14 was to ensure rigor and the highest standard of the peer-review process, drawing from expertise developed through the Institute’s work on major global assessments such as the IPCC reports and in coordinating the 2012 Global Energy Assessment. IIASA Energy Program Director Keywan Riahi and researcher Mathis Rogner led and coordinated the review process.

In addition, IIASA researchers contributed scientific findings to the report: Mitigation of Air Pollution and Greenhouse Gases Researcher Wilfried Winiwarter served as a Coordinating Lead Author, and Risk, Policy, and Vulnerability Program Deputy Director Reinhard Mechler was a Lead Author.
