Warmer winters become reality by Ivana Bruderova

More and more researches of institutes and Universities about winters temperatures finish with the same final result. According scientists from the various states the warming winters and still less snowfall become reality in the last years. From 1965 to 2005 temperatures from December to March increased about 2.5 degrees and days when was on the ground at least 1 inch of snow decreased 9 days on average. This decrease in much observed between 42 and 44 degrees latitude include for instance part of New Hampshire, state of New York or Massachusetts. The fact how much snow falls on some area depends on several factors as closeness of sea, ground level or others. Swinging out of warmer and colder winters wasn't rare in the past but now still higher temperatures are trend which will last. There are two possible reasons of decrease of snow-covered days. The first is higher temperature and the second snow-albedo feedback. This means that the black color of ground not covered with snow absorb more sunshine and so it is less conductive for new snow cover. The less of snow has also commercial impact. Ski centers operators are not satisfied with this trend of warming winters, the starts of ski seasons are often moved afterward because nor the snow making guns can be used when the temperatures are too high. The scientist have warned of global warming and weather changes years before. Nowadays unfortunately still many people don't want to hear thinking it is not their problem because nature end for them behind the enclosure of their garden.
