Prof. Dr. Josef Settele is Head of Animal Ecology and Social-Ecological Research at the Dept. of Community Ecology, Helmholtz Centre for Environmental Research – UFZ (Germany), and Co-Chair of the Global Assessment of IPBES (Intergovernmental Platform of Biodiversity and Ecosystem Services). He was Coordinating Lead Author in the last Assessment Report of the IPCC for the chapter “Terrestrial and Inland Water Systems”. He did his Masters in Agricultural Biology and his PhD in Agriculture. Since 1993 he coordinated several national and international biodiversity and ecosystem related research projects. He is author of more than 450 scientific publications, including more than 40 book projects and more than 160 ISI-listed papers (of which 20 publications are in the internationally renowned journals Science, Nature, Nature Climate Change, Nature Plants, Nature Ecology and Evolution and Nature Communications).

Climate change is projected to be a powerful stressor on terrestrial ecosystems in the second half of the 21st century, especially under high-warming scenarios such as RCP6.0 and RCP8.5.
Direct human impacts such as land use and land use change, pollution, and water resource development will continue to dominate the threats to most terrestrial ecosystems globally over the next 3 decades. Changing climate exacerbates other impacts on biodiversity. Ecosystem changes resulting from climate change may not be fully apparent for several decades, owing to long response times in ecological systems.
Model-based projections imply that under low to moderate warming scenarios (e.g., RCP2.6 to RCP6.0), direct land cover change will continue to dominate over (and conceal) climate-induced change as a driver of ecosystem change at the global scale; for higher climate change scenarios, some model projections imply climate-driven ecosystem changes sufficiently extensive to equal or exceed direct human impacts at the global scale.
In high-altitude and high-latitude terrestrial ecosystems, climate changes exceeding those projected under RCP2.6 will lead to major changes in species distributions and ecosystem function, especially in the second half of the 21st century.
