Global Temperature Time Series
Dataset Overview
This dataset consists of global temperature anomaly time series, compiled from two major sources:
GISS Surface Temperature Analysis (GISTEMP)
Global component of Climate at a Glance (GCAG)
Two datasets are provided:
Global monthly mean temperature anomalies
Annual mean temperature anomalies
All temperature values are reported as anomalies in degrees Celsius, relative to a standardized base period.
