The clearest evidence for surface warming comes from widespread thermometer records that, in some places, extend back to the late 19th century. Today, temperatures are monitored at many thousands of locations, over both the land and ocean surface. Indirect estimates of temperature change from such sources as tree rings and ice cores help to place recent temperature changes in the context of the past.

In terms of the average surface temperature of Earth, these indirect estimates show that to was very likely the warmest year period in more than years; the most recent decade, , is the warmest decade in the instrumental record so far since Figure 1b.
