Find data on atmospheric trace gases and aerosols, oceanic trace gases, vegetation response to CO2 and climate, greenhouse gas emissions, and more.

The Climate and Clean Air Coalition is the only global effort that unites governments, civil society and private sector, committed to improving air quality and protecting the climate in next few decades by reducing short-lived climate pollutants across sectors.

The U.S. Department of Energy's Office of Scientific and Technical Information has compiled free datasets on the environment, energy and science.

Atmosphere discipline data sets focus primarily on characterizing the Earth’s troposphere and stratosphere. Within those layers occur many geophysical processes involving clouds, aerosols, precipitation, lightning, chemistry, temperature, radiation balance, and dynamics. Interactions of the atmosphere with land and ocean surfaces, and with solar radiation also fall within this discipline. EOSDIS DAACs hold over 2700 atmosphere data sets.

Basic information, reports, graphs, and raw data available free from the Environmental Protection Agency.

The Global Carbon Project provides links to environmental and climate data monitoring projects from all over the world.

The IPCC was set up by the World Meteorological Organization (WMO) and United Nations Environment Programme (UNEP) to provide policymakers with regular assessments of the scientific basis of climate change. Reports and data are available free online.

The mission of “Global Climate Change: Vital Signs of the Planet” is to provide the public with accurate and timely news and information about Earth’s changing climate, along with current data and visualizations, presented from the unique perspective of NASA, the world’s leading climate research agency.

NOAA's National Centers for Environmental Information (NCEI) is responsible for providing public access to United States climate and historical weather data and information including drought, precipitation and extreme weather.

"Provides high quality online educational resources for teaching and learning, with current emphasis on the sciences, technology, engineering, and mathematics (STEM) disciplines."

A collection of resources for science educators and students, including archived web seminars, virtual conferences, and comprehensive collections of resources organized by topic and grade level. Numerous collections can be found on climate science.

Choose from hundreds of scientific data sets, focusing on the cryosphere and its interactions. Data are from satellites and field observations, and are from NASA, NSF, NOAA, and other programs.

National Oceanic and Atmospheric Administration (NOAA)'s climate page has maps & data on atmospheric composition, solar radiation, greenhouse gases, and more.

NRDC is tackling the climate crisis at its source: pollution from fossil fuels. We work to reduce our dependence on these dirty sources by expanding clean energy across cities, states, and nations. We win court cases that allow the federal government to limit carbon pollution from cars and power plants. We help implement practical clean energy solutions. And we fight oil and gas projects that would pump out even more pollution.

A non-profit project of the University of Oxford and the Global Change Data Lab, global statistics analyze progress on the 17 United Nations Global Goals for Sustainable Development.

Online data base/portal for collecting, sharing and tracking information about International Climate Initiatives (ICIs) currently in operation that have potential to contribute to reduction of greenhouse gas emissions.

Research and reports compiled by the World Bank on global climate change and poverty, carbon pricing, energy, disasters, adaptation and mitigation.

The World Environmental Organization (World.Org) is devoted to the preservation of the natural diversity of plant and animal species, and their habitats, through the prevention of environmental degradation and destruction. World.Org develops and implements scientific strategies for decreasing fossil fuel use, preventing climate change, and preserving plant and animal species and their habitats.
