The International Scientific Conference “Our Common Future under Climate Change” will take place at UNESCO (Paris) in July 2015. This four-day conference will be the largest forum for the scientific community to come together ahead of the 21st UNFCCC Conference of the Parties (COP21), which will be hosted by France in December 2015 (“Paris Climat 2015”). Building on the results of IPCC 5th Assessment Report (AR5), the Conference will address key issues concerning climate change in the broader context of global change. It will offer an opportunity to discuss solutions for both mitigation and adaptation issues. The Conference will also welcome Side Events organized by different stakeholders. The conference is organized under the umbrella of ICSU, Future Earth, UNESCO and major French research institutions, with the support of the French Government.
