Global Temperature Trend : The Land-Sea Temperature Anomaly

An excellent source of up-to-date visualizations illustrating climate change can be found at

A discussion of climate model predictions vs observations can be found here.

Predictions of Climate Models vs Observations:


Global Temperature Trend – Land-Sea Temperature anomaly:
Note the similar trends for CO2 concentrations in the atmosphere and the temperature anomaly trend (departure from long-term temperature averages), and lack of correlation between those temperature trends and sunspot activity.

Data Sources
•Global mean temperatures are from:
NASA data collection and analysis methods.
•Average number of sun spots per year are from:

•Exact CO2 measurements are from:
