Temperature records from five groups are shown in the figure below: NASA, NOAA, the UK's Met Office Hadley Centre / UEA, the non-profit Berkeley Earth, and
a record by independent researchers Cowtan and Way.
Repeatable in science refers to the ability to test the same hypothesis, using the same methods (typically
by independent researchers), to confirm or reject said hypothesis, e.g. the repeated observation
by many, many different
researchers of fossils in the correct temporal and morphological relationships within the fossil
record (no rabbits in the pre-Cambrian, no humans alongside dinosaurs, etc).
