Well,
    Strange but true on news not long ago.  The anchor person asked the scientist about what was going on with the near record and record dome of heat over the middle of the country that had drifted east over the east coastal areas.  Scientist described how a dome of high pressure built in and then all the fossil fuel emissions pumped into it making it something that could hardly be affected or moved by normal weather.  He described how the cold fronts from Canada were only bouncing off the dome of thick, humid air filled with the smoke of millions of auto exhausts and hundreds of oil and coal fired power plants; bouncing off with little effect save along the edges.

    After he was done the news guy asked him: "well what can be done?"  The scientist looked at him like he was an idiot and said: "stop driving internal combustion powered automobiles."  The news guy just looked at him like "what else?"  but the answer had been given twice, once by the clues given in the orig. explanation, again point blank.  So the dome has retreated back into the midwest and the East into more normal temps; however, Texas and nearby areas have been baking under 100 plus temps for over a month now, and without any rain.  Cattle are being sold to slaughter due to lack of food and water for them by the ranchers.  Any guess what will happen to price of beef come fall?  Ag crops in affected areas as well?  The fields have long ago turned dirt brown after the crops died from lack of water and excessive heat.

   Meantime Europe has been in unusual cold?  If you saw the recent Grand Prix race in Germany?  People had on their coats and jackets due to temps below 55F.  The colder than normal summer pattern has been ongoing for awhile now.  And in south america, Chile had 6 ft of snow.  If this is an indicator of the coming winter here, like last year, a colder than normal winter in the southern hemisphere was followed by the same here in the northern hemisphere.  Guess we will see.
