About
Tracking the significant warming of the Earth's surface, these records provide a detailed history of the Global Land-Ocean Temperature Index from the late nineteenth century to the present day. Recent data confirms that global temperatures are currently at their highest in over two millennia, with nineteen of the warmest years on record occurring since the year 2000. The only exception in this recent trend was 1998, a year significantly influenced by a powerful El Niño event. This collection serves as a critical baseline for understanding long-term climate shifts and the accelerating pace of global heating.
Columns
- Year: The specific calendar year of the observation, ranging from 1880 to 2020.
- No Smoothing(C): The annual mean temperature anomaly in degrees Celsius, representing the direct deviation from the historical baseline without statistical adjustments.
- Lowess(C): A smoothed version of the temperature anomaly using the locally weighted scatterplot smoothing (Lowess) method to highlight long-term trends by reducing year-to-year noise.
Distribution
The data is contained within a single CSV file titled
GlobalTemp.csv, which is approximately 2.26 kB in size. It consists of 141 unique records, providing 100% validity across all three columns with no missing or mismatched entries. The dataset maintains a perfect usability score of 10.00 and is provided as a static record of historical temperature shifts.Usage
This resource is ideal for climate researchers and environmental scientists who require a verified historical record to validate climate models. It is well-suited for educational purposes, providing a clear visual representation of the upward trajectory of global temperatures. Additionally, data analysts can use the smoothed and non-smoothed variants to practice time-series forecasting and trend analysis within the context of earth science.
Coverage
The geographic scope of this record is global, capturing combined land and ocean temperatures across the entire planet. Temporally, the data provides a continuous annual series starting in 1880 and concluding in 2020. This span offers an exhaustive look at the industrial and post-industrial era's impact on the Earth's thermal equilibrium.

Who Can Use It
Environmental researchers can leverage these records to study the correlation between industrial activity and rising surface temperatures. Educators may utilise the year-on-year anomalies to illustrate the reality of global warming to students. Furthermore, policy advisors and non-governmental organisations can use the verified NASA-sourced data to support initiatives aimed at climate mitigation and international environmental agreements.
