Early last glacial intra-interstadial climate variability recorded in a Sardinian speleothem
Chemical and physical proxy data from a precisely dated early last glacial (~113e110 ka, MIS5d) Sardinian stalagmite reveal a sub-millennial-scale, cool-dry climate event centered at 112.0 þ0.52/-0.59 ka, followed by a rapid return to warm-wet conditions at 111.76 þ0.43/-0.45 ka. Comparison with reg...
