● Combined ● UAH ● RSS ● HadCrut ● GISS ● AMO ● PDO ● CET ● Sea Ice ●

There are 4 main sources of climate data, 2 based on satellite instruments and 2 based on thermometers. These are UAH RSS HadCrut and GISS

Combining data from the various data sources into one graph

First as downloaded from the data sources themselves

Then aligned from 1979-Today so as to bring them into a common framework

Then with some proxies added to get another 50 years and add some context

Proxy alignments to HadCrut over their overlap periods

Data sets from just 1979 onwards

Initial trends from sources to show how the alignments are made

Trends after OLS alignments so as to bring them to a common baseline
