The Design Climatology Branch of the Air Force Cambridge Research Laboratories had the scientific responsibility for leading a DoD Task Group effort to revise MIL-STD-210A 'Climatic Extremes for Military Equipment'. This document represents the fruition of the goals of the task group. It relates the background studies supporting the values in MIL-STD-210B, so that MIL-STD-210B users need to consult only this single document for an elaboration on the MIL- STD-210B extremes. In addition, the report contains information on the origin, necessity for and the events leading to a revision of MIL-STD-210A. Discussions of the major changes in the Standard's philosophy and its contents are also provided. ; "Aeronomy Laboratory Project 8624." ; "24 January 1974." ; Includes bibliographical references. ; The Design Climatology Branch of the Air Force Cambridge Research Laboratories had the scientific responsibility for leading a DoD Task Group effort to revise MIL-STD-210A 'Climatic Extremes for Military Equipment'.

The Genesis strategy that Schneider proposes is to stockpile grain in good harvest years against the inevitable bad years. The United States must do this, he argues, because 90 percent of the global grain supply consumed outside of its continent of origin comes from North America.

It is with both pleasure and sadness that we dedicate this special climate change issue of Portal to the late Dr. Stephen H. Schneider.

Steve, as he was known to his friends and colleagues, was as rare a bird as any he sought out in his passion as a birdwatcher. A brilliant climate scientist, author of countless books and papers, path breaking inter-disciplinarian, eminent public communicator, mentor to dozens of young scholars; the list of roles and adulatory adjectives could fill an IPCC special report.

Steve would have appreciated this special issue, with its multidisciplinary approach, and its quest for solutions based on analytical scholarship. He understood better than most the inseparability of normative and descriptive concerns, the need for academics and scientists of all kinds to be involved with public processes of communication, policy design and deliberation. While his last book was called "Science as a Contact Sport," the unspoken title of his career might have been "Science as a Public Service." He was endlessly testifying, consulting and giving interviews, and encouraged others to learn to do the same.

Notwithstanding a battle with lymphoma in the last decade (chronicled in the wonderful book The Patient from Hell), Steve maintained a frenetic level of activity and was still going strong when he was felled by a pulmonary embolism in July of 2010 at age 65. He leaves behind a legacy embodied in his publications, institutions like the IPCC and the journal Climatic Change, and in the hearts and minds of the countless persons he interacted with, mentored, and loved. Exuberant, passionate, full of warmth and good humor, Steve was a mensch among mensches. He will be sorely missed.

Human remains firmly associated with Mousterian artifacts and exhibiting characteristics transitional between those of Neanderthal and fully modern man are known from two Levantine sites. A survey of the archeological evidence suggests that three climatic zones were differentially exploited by Neanderthal man and that some of the sites document a shift in subsistence away from a generalized hunting pattern to the specialized hunting of large, migratory herd animals. The hypothesis is offered that the formal changes documented for the Upper Paleolithic occurred in response to this basic shift in human ecology.
