Many scientists have specified various reasons for global warming effects on the environment and for human life. It is not easy to point one reason for global warming effects, but recently you might have saw many change in global climate. Global warming effects have various consequences such as glacier volume decreasing, rise in sea levels, shrinkage of Arctic and altered fashion of doing agriculture have been named as direct effects on global warming. Secondary global warming effects are extreme weather events, increase in tropical diseases, changes in the timing of seasonal patterns in ecosystems, and drastic economic impact.

Before many times back, many scientist and researchers were hopping that a positive effect of global warming would be increased agricultural yields(outputs), because of the role of carbon dioxide in photosynthesis which might behave in positive manner, but now it resulting in destructions of several crops. In the area of Iceland, due the rising temperatures which have made possible the widespread sowing of barley easily in an effective manner, which was not possible twenty years from now. The net result is expected to be that 33% less maize—the country's staple crop—will be grown. The reduction in rainfall has turned millions of land into deserts.

Insurance industry has been affected very badly with the risk of insurance; the number of major natural disasters has been increased to 300% since 1960s, and insured losses increased fifteenfold in real terms. According to Choi and Fisher (2003) each 1% increase in annual precipitation could enlarge catastrophe loss by as much as 2.8%.

A Power Move is any type of move in Bboying which requires spinning and/or rotating in a way that can be done so in multiple rounds. All Power Moves (or series of a type of Power Move) can be connected in combos to form a "Power Combo". Breakers that use mostly Power combos in there sets are commonly known as "Power Heads". Example: Flare-Air Flare-Elbow Air Flare-Air Flare-1990...etc Or-Air Flare 1.5-Babymill-Windmill-Swipe-Windmill-Halo-Headspin...etc The possible number of combinations are endless and only limited by stamina, strength and imagination. In 2002 The Guinness Book of World Records began tracking number of power move rotations for their world record standings. At that time Canadian Gregory Burbidge broke records for Air Flare, Headspins, and Elbow Airflares. American Lauren Jacob held the record for Chair Flares. American Laura Derrick held the record for Tappingmills. Nicole Jones (nationality unknown) held the record for Munch Airflares. In 2004 Guinness removed these titles from their records. At the time Gregory Burbidge was the only one who still held records from the original group.
