Phillipps' lies about global warming is to plant a little truth, not a tree that produces methane while growing that is a far worse greennhouse gas than CO2. Under our genius environmentalist PRESIDENT GEORGE W. BUSH... For over a century, a national network of “weather nerds” (for lack of a better term) have monitored backyard weather stations where they kept track of daily maximum and minimum temperature and precipitation using standardized instruments and measurement techniques. But NOW... But the utility of the co-op records to climate analysis was limited by their cumbersome, paper format. However, recently the interest in climate change spurred the government to digitize these paper records, thus adding many new stations to the existing network. With the addition of the co-op data, the number of stations from roughly 1890 to 1947 doubled or tripled relative to the previous baseline. FROM THIS .... These updated records shed new light on the behavior of U.S. extremes. Not only did the frequency of extremes vary markedly in the early 20th century days of very low greenhouse gas levels, but the frequency of extreme events in the late 1890s was at least comparable to that in our current climate. The heat wave record (Figure 2) is dominated by the huge spike during the 1930s “Dust Bowl” era. In fact, the recent period is hardly noticeable in the longer-term context, even though the number of heat waves has increased recently compared to the cool summers of the 1960s and 1970s. You might argue that not too much should emphasis should be placed on the United States weather records. The Lower 48 account for only 2 percent of Earth’s surface. But this is a cautionary tale about data. The U.S. has the most dense long-term weather records of any similar-sized place on the planet. Note how the addition of early observations can completely change one’s interpretation of the trend (as in Figure 1). If we are faced with such uncertainty with the world’s best data set, how much confidence can we really place in our interpretations of the very sparse records from Africa, Asia, and South America, not to mention the paucity of records from the world’s oceans? As with all issues of global climate change, the devil’s in the details, but details about weather records hardly make for blockbuster headlines.worldclimatereport.com
