Fortunately, the world’s governments are now fully convinced of the scientific evidence of climate change and the need to take urgent action. More research and investment is needed for advancing low-carbon technol- ogies, particularly in the energy sector. But already many policies, technologies and actions are available, and their deployment needs to be scaled up. Individual citizens, community leaders, businesses, civil society organiza- tions, governments and the United Nations system must all contribute.
Science will continue to play a vital role. Continued and improved scientific observations of the climate system will make it possible to monitor progress in reducing emissions of heat-trapping greenhouse gases. Continued and improved scientific research will lead to a better understanding of climate change at the national and regional levels, of its impacts, and of solutions for adaptation. Science will also help to identify practical solutions for reducing greenhouse gas emissions and steering the international community towards a greener future.
The World Meteorological Organization is committed to contributing to these efforts. WMO co-sponsors and hosts the Intergovernmental Panel on Climate Change, whose regular assessment reports provide a strong basis for policy action. WMO is also the main co-sponsor and the host of the Global Climate Observing System and the World Climate Research Programme. The growing network of WMO Regional Climate Centres and Climate Outlook Forums is building capacity at the national and regional levels. WMO plans to develop an integrated greenhouse gas monitoring system for informing decision-makers about progress in reducing greenhouse gas emissions.
The world’s National Meteorological and Hydrological Services and their partners are also collaborating through WMO to implement the Global Framework for Climate Services. Climate services translate scientific knowledge into practical action for climate resilience, climate adap- tation and mitigation, and sustainable development. By integrating climate information, climate predictions, and socioeconomic and other relevant data and information into customized products, climate service providers empower decision-makers to address climate risks and opportuni- ties. Climate services are already guiding action in such climate-sensitive sectors as agriculture, water resources, disaster management, public health and energy.
Because climate change poses a fundamental challenge to humanity, it is integrated into the United Nations Sustainable Development Goals that will drive the global agenda through the year 2030. By acting on the basis of the best available science, and drawing on growing reserves of political will and public support, the international community can succeed in building an environmentally sustainable and economically prosperous world.
