~I / WEEKLY NEWSLBTTER 94-10 PERIOD JULY 3 - JULY 10, 199 ~eneral "Interes1;; Some scientists are ques-cioning long-held beliefs supporting the concepts of the existence of the climatic events commonly known as: (1) the Little Ice Age, and (2) the Medieval Warm Period. This has important implications for the many true-blue believers in global warming who think this is a unique moment in the earth's climate history. An erticle in the June-JUly issue of k?eatherwise, states, "Through anecdotal evidence and the somewhat murky picture of past eJ.'l.l!l>lt"l derived from tree rings, ice cores and other sources, two worldwide periods of past climate have come to be accepted as tact: the Little Ice ~ge was a 400-year cooling period ending in the 19th century, and the Medieval ~arm Period, high temperature of the 8th through 14th centuries. Recent comparisons of the many paleo- climatic records from around the world show that global climate trends were rare, even nonexistent. The climate of the paat, it turns out, was no less comple~ than the one we know today." Two researchers who recently have taken a more "microscopic" look at climatic history are: Malcolm Hughes of the university of Arizona's Laboratory of Tree-Rin~ Research and Henry Diaz of the Nat10nal Center for Atmospheric Research (NCAR). Their conclusion was that the idea of centuries-long events or trends Was much too simplistic and, "... things were coming and going in much the sarne way they have done in modern times." They say, for example, the Little Ice Age,"...was marked by seasonal and regional variations, both warm and cool, an the scale of decades, not centuries.~ They point out that while data from western Russia has suggested cooler conditions for the lSO-year period 1600-1750, there were warmer conditions for a 100 years longer. Western North America was warm during one lO-year periOd, 1650-1660, while eastern ChinA and Korea, simultaneously, were having an exceptionally cold decade. These researchers ask that whan we think about the past 10 years of above-average (global) warming, we also should pause and remember that Greenland, the North Atlantic and North Pacific have all been cooling since the 19408. =.======================~~~~c~==~.==~~=~~z~~:====~~=~~~==~c~=~=== OPERATIONS (All times given are CDT): JULY 3rd - OPERATIONAL DAY ~26: By late afternoon a NNE-SSW line of storms had formed south of Ford County. Initially, two cloud baee planes were scrambled at 4:45 ~.m. to standby at Dodge City as a precaution. However, "within a few minutes overshooting tops within the line indicated a very severe storm developing south of Ford County which would be moving NNE toward it. Another baSe plane and the cioud top plane were scrambled as well; the fifth plane was scrambled at 5:18 p.m. as a ~recaution against other severe storms developing near Stanton and Grant counties.
