Sweden played host this month to a gathering of politicians, administrators and research scientists taking part in a review of the first order draft of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Global Warming of 1.5 °C (SR15).

Director of UQ’s Global Change Institute, Professor Ove Hoegh-Guldberg, one of the coordinating lead authors of the oceans chapter in the latest IPCC, attended the Malmö meeting as part of a team addressing nearly 13,000 comments from expert reviewers in 61 countries as they prepare the second draft of the Special Report on Global Warming of 1.5 °C.

The Swedish Government sent a top-level delegation to the meeting, which was opened by the country’s Deputy Prime Minister Isabella Lövin (also Minister for International Development Cooperation and Climate).

The IPCC reports are part of the UN assessment cycle – designed to bring a solid scientific consensus to negotiations such as those which occurred at COP21 talks in Paris, December 2015.

The resulting Paris Climate Agreement provided a critical backdrop to the next cycle of IPCC assessment reports.

It calls for the international community of more than 195 countries to limit global warming to two degrees over pre-industrial levels with an ideal target of 1.5 degrees.


Professor Hoegh-Guldberg, who has been a strong voice in the science community on the urgent need to limit global warming to less than two degrees over pre-industrial levels, said it was a great honour to be chosen to help provide a structure for the reports.
