NASA Climate
climate.nasa.gov
NASA's climate change portal with real-time data visualizations, interactive charts, and downloadable datasets covering global temperature, sea level, CO₂ concentration, ice coverage, and ocean heat from NASA satellites.
Why it is useful
Primary-source climate data directly from NASA's scientific missions, presented clearly enough to use without a science background. Visualizations are publication quality and CC-licensed. The 'Eyes on the Earth' interactive 3D globe lets you explore satellite data in real time. Useful for journalists, educators, and researchers wanting data rather than commentary on climate trends.
