Reliable Web resources for climate science

Climate Toolkit is a comprehensive set of educational resources on climate science. It offers many ways for students and climate advocates to engage interactively with climate models and to explore some of the basic science and impacts of climate change.

EnRoads is a free, user-friendly computer model that educators, policymakers and citizen advocates can use to understand how Earth’s climate system will respond to policy initiatives.

The NSF-sponsored University Corporation for Atmospheric Research (UCAR) offers a valuable set of resources for earth and climate science education, with materials for both students and instructors.

Reconstituted by the Biden administration, the US Environmental Protection Agency (EPA) is once again a good source of reliable information about climate change. EPA has partnered with many other groups to create a compilation of 50 lead indicators of climate change, covering greenhouse gases, weather and climate, oceans, snow and ice, health and society, and ecosystems.

NASA’s Earth portal provides information on all components of Earth’s climate system (air, water, ice, land, and biosphere). It also offers free images, videos and media resources.

The National Snow and Ice Data Center (NSIDC) at the University of Colorado is a portal to a large number of reliable resources on all aspects of the cryosphere.

The Fourth US National Climate Assessment includes a comprehensive description of the physical science of climate change (Volume I) and a second volume on climate impacts, risks and adaptation in the US (Volume II). Volume II includes very valuable descriptions of specific climate impacts in ten distinct regions of the US.

Through its portal, the National Oceanic and Atmospheric Administration (NOAA) is the primary US government agency tasked with providing science and information for a climate-smart nation. It offers news and features for the public, a comprehensive array of maps and data, and resources for learning and curriculum development.

The United States Geological Survey (USGS) offers information about many aspects of Earth science that can affect us, including natural and manmade hazards (such as floods and landslides), ecosystem health and biodiversity, and the impacts of climate change.

CarbonBrief is a superb UK-based website that covers the latest developments in climate science, climate policy and energy policy.

The Global Carbon Project partners with the global scientific community to establish a knowledge base about the global carbon cycle and how it is affected by anthropogenic greenhouse gas burning and land use change. Detailed information about carbon dioxide, methane and nitrous oxide is available.

RealClimate is a site built by climate scientists for journalists and the public. It offers links to resources on global warming basics and on debunking claims by denialists.

The Skeptical Science website offers detailed debunking of nearly 200 false or misleading claims about climate science.

The Consensus Project measures the level of agreement among climate scientists that global warming is human-caused. News Flash: The Debate Is Over.
