Global Warming: Extreme Weather & Seasonal Mismatching Recent climate modeling results indicate that "extreme" weather events may become more common. Rising average temperatures produce a more variable climate system. Carbon dioxide from cars, industries and power plants trap heat near the earth 's surface. More heat means more energy. Adding more energy to the atmosphere creates the potential for more extremes. Climatologists say extreme weather events will become more common as our climate heats up. The gradual increase in the overall temperature of the earth 's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants is known as Global Warming. The greenhouse effect is when the Earth 's atmosphere becomes thick with gases, such as Carbon dioxide, and substances which trap the sun 's radiation, making the Earth warmer. The extreme weather is leading to climate changes which are resulting in seasonal mismatching.
The Earth 's seasons have shifted back in the calendar year, with the hottest and coldest days of the years now occurring almost two days earlier. Temperatures over land in the 100-year period between 1850 and 1950 showed a simple, natural pattern of variability, with the hottest day of the year in the Northern Hemisphere landing around July 21. But from the mid-1950s onward (the period when global average temperatures began to rise), the hottest day came 1.7 days earlier.
