More Evidence of Climate Change

[MindMover]

Surface temperature over the land and ocean temperature is rising across the globe. These plots show land, ocean, and merged land and ocean surface temperature (radio buttons) for both the Nothern Hemisphere and the globe (tabs).

This temperature reconstruction dates back to 1880, and is typically current through the last month. The solid red line is the yearly temperature average, and the shaded pink area illustrates the potential uncertainty associated with the data.
Data source: NOAA MLOST.
