Below is a rough comparison of contemporary Global Warming and estimates of past temperature change. This is a visualization in the vein of this plot on Wikipedia. Uncertainties increase substantially as estimates go back further in time. Time resolution also decreases further back in time so much of the high-frequency climate variability seen more recently would presumably also exist in the more distant past but is not detectable. Sources of data are below.
