    Generally, the atmosphere contain mainly of nitrogen and oxygen with trace amounts of water vapor. Now, due to excessive emission of carbon dioxide and nitrogen oxides from fossil fuels, methane from organic waste materials and other gases begin to be part of the atmosphere. The Heat capacity of the atmosphere increases as the amount of the emission increases. The Ultraviolet rays from the sun normally bounces back to the space but now it is absorbed by these gases through radiation ( a mode of heat transfer). As the heat is absorbed, the more turbulent the atmosphere becomes. These explains why the hurricane increases its intensity. Likewise for tornadoes and hailstorms.

    The cost of energy for greenhouse heating has increased considerably over the past several years. In response to high energy prices, greenhouse growers are seeking strategies to improve energy conservation and delving into alternative energy sources.

    Well in a green house what is used to raise the temperature? you in case it in glass but that alone will only produce dry heat. Now in earths green house effect the temperature is raised by the addition of water vapor, this process is also used in green houses around the world to produce a environment that is more hospitable to plants.
    Now as for the energy transference plants take Co2 that we produce by various means and together with sunlight and chlorophyll in a process of photo geneses they create oxygen that we breath in and then the cycle starts all over again.
    The Co2 level in our atmosphere at this time is 300 parts per million. Research has proven that plant thrive in Co2 levels as high as 1600 ppm, they grow faster, and larger. Also Co2 is the limiting factor in plant growth.
    So you come to an impasse where the world will not survive without plants and plant will not survive without Co2.

    The earth is producing avoidable emissions that lead to global Meltdown which we have to cut down on to avoid extinction of the Human race!
