Fig. 4: Spatial expression of the 8.2 ka and 4.2 ka climate excursions.
From: The 4.2 ka event is not remarkable in the context of Holocene climate variability
Temperature (a, b) and moisture (c, d) excursions are shown for excursions centered at 8.2 ka (a, c) and 4.2 ka (b, d). The grid shading indicates the significance of regional net excursions. Darker red indicates more significant net temperature excursions (i.e., the number of warm excursions in a region significantly exceeds the number of cold excursions). Blue colors indicate regions where cold excursions significantly exceed the number of warm excursions. Green (wet) and brown (dry) colors express regional net excursions for hydroclimate. Transparency of grid shading increases with distance from the nearest site. Colored dots show the ___location of records with significant excursions at the 0.05 level, colored similarly to grid shading. White circles indicate no significant excursions at a site for the specified time period.
