This Synthesis Report is based on the reports of the three Working Groups of the Intergovernmental Panel on Climate Change (IPCC), including relevant Special Reports. It provides an integrated view of climate change as the final part of the IPCC’s Fifth Assessment Report (AR5). This summary follows the structure of the longer report, which addresses the following topics: Observed changes and their causes; Future climate change, risks and impacts; Future pathways for adaptation, mitigation and sustainable development; Adaptation and mitigation.

.This Asian Development Bank (ADB) study examined the economic costs associated with the impacts of climate change and the cost and benefits of adaptation in Bangladesh,Bhutan, India, the Maldives, Nepal, and Sri Lanka. The study aimed to (i) assess the biophysical impacts of climate change in the region, including individual country impacts, and (ii) estimate the total economic loss to the countries in the region by 2100, taking into account the different scenarios and impacts projected across vulnerable sectors, and then to estimate the magnitude of funding for adaptation measures required to avert such potential losses. Results of the study will aid development of future policies and programs for climate change adaptation in the region, including initiatives for regional cooperation and capacity building in climate change management. The study covered the following sectors: agriculture, terrestrial ecosystems, water, marine and coastal resources (except Bhutan and Nepal), health, and energy.
