Worldwide Temperature Trends 1961–2024

This dataset captures how land surface temperatures have changed across almost every country over the past six decades. Rather than raw temperatures, it provides temperature anomalies — the difference between a location’s observed temperature and a long-term baseline (1951–1980). Anomalies are the clearest way to see climate shifts: they remove seasonal and geographic offsets so you can compare trends across places and over time.

The records are derived from the widely used NASA GISTEMP product and repackaged by FAOSTAT into analysis-ready tables. That means you get scientifically vetted measurements presented in tidy and wide formats, so you can jump straight into visualization, statistical modeling, or combining these values with economic, health, land-use, or emissions data using standard ISO3 country codes.

Why this matters: trends in temperature anomalies reveal where warming is greatest, where variability is increasing, and how quickly climates are shifting — information vital for climate science, policy planning, risk assessment, and public storytelling. Because values are anomaly-based and span 1961–2023, the dataset supports robust trend estimation (for example, degrees per decade), extreme-event context, and longitudinal comparisons between regions.

Who benefits most: data scientists, climate researchers, students, journalists, NGOs, and civic technologists who want a reliable, easy-to-merge temperature signal to power maps, dashboards, clustering, forecasts, or correlation studies (e.g., linking warming to emissions, deforestation, or public health outcomes).

Key practical advantages:

Ready-to-use: tidy and wide formats for Pandas, R, and visualization tools.

Consistency: ISO3 codes included to avoid name-matching problems when joining with other country-level datasets.

Comparability: anomaly values referenced to a standard baseline (1951–1980), enabling fair comparisons across countries and decades.

Depth: annual coverage from 1961 through 2023 (monthly and seasonal variants available in source data if you need higher temporal resolution).
