To determine rainfall patterns in the northern-central Indo-Pacific region (NCIP), researchers reconstructed a speleothem δ18O rainfall record, from 706 BC through 2004 AD, from Klang Cave in southern Thailand, and found decreasing rainfall in the NCIP as well as dry climate conditions in the NCIP and southern-central Indo-Pacific during the 20th century's Current Warm Period and the Medieval Warm Period; the authors also found results suggesting that anthropogenic forcing of rainfall may be indistinguishable from natural variability.
