Global Temperature Trend : The Land-Sea Temperature Anomaly

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

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

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.
