New research on tree rings in Utah has revealed that some droughts of the past 576 years were much more severe than anything seen since the start of the 20th century.
A new tree-ring study, led by the University of Arizona, reveals that long-term droughts in Southwestern North America often mean a failure of both summer and winter rains. This contradicts a long held belief that a dry winter rainy season is usually followed by a wet monsoon season, or vice versa.
The National Science Foundation has funded a study to determine past climates by studying tree rings.
Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or even absent growing seasons.
Researchers with the University of Arizona (UA's) have discovered evidence of a formerly unknown, decades-long drought that occurred in the southwestern United States in the second century.
Nibbling by herbivores can have a greater impact on the width of tree rings than climate, new research has found.
Trees are outstanding historians -- In fact, scientists dating back to Leonardo da Vinci recognized the value of trees.
A group of researchers have studied the history of drought in the Pacific Northwest during the last 6,000 years, a time that spans the mid-Holocene geological epoch to the present.
A new, detailed record of rainfall fluctuations in ancient Mexico that spans more than twelve centuries promises to improve our understanding of the role drought played in the rise and fall of pre-Hispanic civilizations.
A team of researchers conducting an extensive study of growth rings in trees say there could be a link between the rise and fall of ancient civilizations and sudden shifts in Europeâ€™s climate.
