Climate Science and Projections

Climate science and projections cover how the federal government measures, tracks, and forecasts changes in the earth’s climate. Agencies collect temperature, ocean, and ice data over long stretches of time, build models to project future conditions, and translate that research into assessments that inform public policy. Understanding this work helps readers judge what is known with confidence, what remains uncertain, and how that uncertainty gets handled in political debate.

Who does the measuring. Much of the government’s climate data comes from a small set of scientific agencies that run satellites, weather stations, and ocean sensors around the world. What the National Oceanic and Atmospheric Administration (NOAA) Does explains how one of these agencies fits into that system, while Purpose of the National Oceanic and Atmospheric Administration (NOAA) lays out the broader mission behind that work.

How the data gets used. Raw measurements only matter once they’re compiled into indicators and trends that show how fast conditions are shifting. How Government Data Shows Climate Change Is Accelerating walks through how federal indicators are built and read, and How NOAA and NASA Coordinate Climate Monitoring—And What They Tell Policymakers looks at how separate agencies combine their findings for decision-makers.

Where science meets politics. Climate findings feed into national assessments and public debate, and both are shaped by ongoing arguments over method, funding, and interpretation. The Future of the National Climate Assessment covers how that reporting process works, and Debate: Climate Skepticism in the United States examines the disagreements that surround the science itself.
