Title : Science aspects of the 2°C and 1.5°C global goals in the Cancun Agreements
Date : 01 May 2012

This paper reviews the scientific literature on impacts for 1.5 and 2°C warming levels with focus on risks for LDCs. We summarize observed impacts in LDCs that have been related to global mean temperature and provide an overview of projected future changes. This comprises a wide range of impacts along the causal chain of global warming: sea level rise, extreme events (e.g. droughts, floods, tropical storms), impacts on natural ecosystems, economic impacts (e.g. on agriculture, fisheries, tourism), food and water security, and health.
