A/RES/66/288 Climate change 190. We reaffirm that climate change is one of the greatest challenges of our time, and we express profound alarm that emissions of greenhouse gases continue to rise globally. We are deeply concerned that all countries, particularly developing countries, are vulnerable to the adverse impacts of climate change and are already experiencing increased impacts, including persistent drought and extreme weather events, sea-level rise, coastal erosion and ocean acidification, further threatening food security and efforts to eradicate poverty and achieve sustainable development. In this regard, we emphasize that adaptation to climate change represents an immediate and urgent global priority. 191. We underscore that the global nature of climate change calls for the widest possible cooperation by all countries and their participation in an effective and appropriate international response, with a view to accelerating the reduction of global greenhouse gas emissions. We recall that the United Nations Framework Convention on Climate Change provides that parties should protect the climate system for the benefit of present and future generations of humankind on the basis of equity and in accordance with their common but differentiated responsibilities and respective capabilities. We note with grave concern the significant gap between the aggregate effect of mitigation pledges by parties in terms of global annual emissions of greenhouse gases by 2020 and aggregate emission pathways consistent with having a likely chance of holding the increase in global average temperature below 2° C, or 1.5° C above pre-industrial levels. We recognize the importance of mobilizing funding from a variety of sources, public and private, bilateral and multilateral, including innovative sources of finance, to support nationally appropriate mitigation actions, adaptation measures, technology development and transfer and capacity-building in developing countries. In this regard, we welcome the launching of the Green Climate Fund, and call for its prompt operationalization so as to have an early and adequate replenishment process. 192. We urge parties to the United Nations Framework Convention on Climate Change and parties to the Kyoto Protocol thereto 51 to fully implement their commitments, as well as decisions adopted under those agreements. In this regard, we will build upon the progress achieved, including at the seventeenth session of the Conference of the Parties to the Convention and the seventh session of the Conference of the Parties serving as the Meeting of the Parties to the Kyoto Protocol, held in Durban, South Africa, from 28 November to 9 December 2011. Forests 193. We highlight the social, economic and environmental benefits of forests to people and the contributions of sustainable forest management to the themes and objective of the United Nations Conference on Sustainable Development. We support cross-sectoral and cross-institutional policies promoting sustainable forest management. We reaffirm that the wide range of products and services that forests provide creates opportunities to address many of the most pressing sustainable development challenges. We call for enhanced efforts to achieve the sustainable management of forests, reforestation, restoration and afforestation, and we support all efforts that effectively slow, halt and reverse deforestation and forest degradation, including promoting trade in legally harvested forest products.
