Climate History of Pantepui, South America

Screen Shot 2019-07-09 at 7.50.37 AM.png

A new climate history of the Pantepui region of southeastern Venezuela and southwestern Guyana demonstrates methods for tracking past climate change in tropical regions. The authors also use their reconstruction to track changes in the biosphere, hypothesizing that the region’s unique biota was preserved through these changes by migrating into lowland areas that today would not support them. The authors also address the difficulties of working in tropical areas where climate proxies usually lack sufficient resolution to create detailed records. Find more about the piece here.

Deep Atlantic Temperature Changes Require Centuries

New research by Geoffrey Gebbie uses proxy data to show that deep Atlantic waters require several centuries to respond to changes in sea surface temperature. As such, deep ocean waters initially cooled during the Medieval Climate Anomaly, and the cooling of the Little Ice Age was not felt at the sea floor for hundreds of years. The trophic cascades of oceanic ecosystems make these findings of particular interest for historical climatologists studying maritime environments. Read the full article here

Svalbard's Climate History

Two new pieces of research profile the climate history of the island of Svalbard in the Arctic Ocean. An article by Dagomar Degroot outlines how changes in the amount of local sea ice alternately facilitated or hindered conflict between Dutch and English whalers in the area, demonstrating how climate change played out on a local scale. Wesley Farnsworth’s recent dissertation provides a detailed overview of glaciation on the island during the Holocene, suggesting in particular that the Little Ice Age brought about quite dramatic advances for glaciers on the island.

Spanish Archival Documents as Sources for Historical Climatology

A new article by Francisco Saulo Rodríguez Lajusticia profiles the usefulness of various Spanish archival sources for understanding climatic events including drought, floods, storms, volcanic eruptions, and earthquakes. Drawing attention to various types of documentation and archival repositories where they can be found, it offers a point of entry for new scholars looking to study climatic trends in Spain, southern Europe, and anywhere else affected by the same climate patterns. Also included is an appendix of several documents reprinted in full. Read the full article here.

New Online Database of Chinese Sources for Climate History

A new open-access article in Scientific Data presents the REACHES climate database based on historical documents of China. This database of thousands of records, principally from the Ming and Qing periods, electronically publishes and encodes many sources previously available only in compilations that were difficult to access or search. The article explains the type of records available and some of the difficulties of interpretation they present.
