TL;DR: The two most severe, sustained droughts in the continental United States during the 20th century occurred in the 1930s and 1950s, according to tree-ring reconstructions of the Palmer drought severity index (PDSI) as discussed by the authors.

TL;DR: In this article, the authors compare tree-ring-based and model-based temperature reconstructions for the Northern Hemisphere from treering width and maximum latewood density over the past 1,500 years.

TL;DR: The authors presented a significant update to a millennial summer temperature reconstruction (1073-1983) that was originally published in 1997 using new tree-ring data (predominantly Picea engelmannii), which is not only better replicated, but has been extended (950-1994) and is now more regionally representative.

TL;DR: In this article, the authors developed the first regional snowpack series (1951-2005) from Chilean and Argentinean snow course records, showing a strong regional signal, marked interannual variability, and a positive, though nonsignificant, linear trend.

TL;DR: In this article, the authors summarize evidence of the latest Pleistocene and Holocene glacier fluctuations in the Canadian Cordillera and present a review focusing primarily on studies completed after 1988, when the first comprehensive review of such evidence was published.
