Key Climate Change Sources & Experts
Leading International Bodies
United Nations | Climate
The 193-member state organization conducts its climate work primarily through various agencies (see below) and via legal instruments including the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol and the Paris Agreement, as well as its sustainable development goals.
Intergovernmental Panel on Climate Change
The IPCC is the United Nations body charged with assessing the science related to climate change. It was set up in 1988 by the World Meteorological Organization and United Nations Environment Programme to provide policymakers with regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. Its reports, including its Fifth Assessment Report, are essential working documents in the climate field.
United Nations Environment Programme | Climate Change
Within the United Nations, UNEP sets the global environmental agenda and promotes the implementation of the environmental dimension of sustainable development within the United Nations system. Among its climate change resources is a roadmap for reaching the 1.5C goal with six key sectors (energy, industry, agriculture and food, forests and land use, and transport).
World Meteorological Organization | Climate
A specialized agency of the United Nations for meteorology (weather and climate) and more, WMO helps its member nations monitor the Earth’s climate on a global scale to help adapt to a changing climate and manage risks. It provides extensive climate monitoring information, including annual reports, seasonal climate updates and regional outlooks.
World Health Organization | Climate Change
The intergovernmental health organization supports countries in building climate-resilient health systems and tracking national progress in protecting health from climate change, including assessing the health gains that would result from the implementation of the Paris Agreement.
International Union for Conservation of Nature | Climate Change
