Intergovernmental Panel on Climate Change (IPCC) produces reports "on the full scientific and technical assessment of climate change." The most current edition was published in 2022.

"The Millennium Ecosystem Assessment provides a state-of-the-art scientific appraisal of the condition and trends in the world’s ecosystems and the services they provide (such as clean water, food, forest products, flood control, and natural resources) and the options to restore, conserve or enhance the sustainable use of ecosystems."

"A basin-by-basin report from the Department of the Interior and the Bureau of Reclamation that characterizes the impacts of climate change and details adaptation strategies to better protect major river basins in the West that are fundamental to the health, economy, security and ecology of 17 Western states."

EM-DAT provides an objective basis for vulnerability assessment and rational decision-making in disaster situations. For example, it helps policymakers identify disaster types that are most common in a given country and have had significant historical impacts on specific human populations.
In addition to providing information on the human impact of disasters, such as the number of people killed, injured or affected, EM-DAT provides disaster-related economic damage estimates and disaster-specific international aid contributions.

The World Meteorological Organization (WMO) is a specialized agency of the United Nations. It is the UN system's authoritative voice on the state and behaviour of the Earth's atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources.

133 Members supply official weather forecasts for 1744 cities. 1718 cities from 166 WMO Members also have their climatological data presented in this web site.

Global focus with uneven coverage of different regions and countries. Historical climatological data for several countries. Data are scanned pdfs for print documents.

US and some global focus. Climate Data Online (CDO) provides free access to NCDC's archive of global historical weather and climate data in addition to station history information. These data include quality controlled daily, monthly, seasonal, and yearly measurements of temperature, precipitation, wind, and degree days as well as radar data and 30-year Climate Normals. Includes storm and severe event data for the US.

Good for gathering background data about general weather trends and data over time.

US Focus. NOAA Climate.gov is a source of timely and authoritative scientific data and information about climate.

Western United States Focus. Links available to other US regional climate centers. Temperature, precipitation, and other weather data available.

United States water management agency covering the 17 western states. Their mission is to "manage, develop, and protect water and related resources in an environmentally and economically sound manner".
