Is it possible for a future ice age?

In quick summary, if enough cold, fresh water coming from the melting polar ice caps and the melting glaciers of Greenland flows into the northern Atlantic, it will shut down the Gulf Stream, which keeps Europe and northeastern North America warm (http://www.baltimorechronicle.com/feb04_IceAge.html). The worst-case scenario would be a full-blown return of the last ice age--in a period as short as two to three years from its onset; and the mid-case scenario would be a period like the "little ice age" of a few centuries ago that disrupted worldwide weather patterns leading to extremely harsh winters, droughts, worldwide desertification, crop failures, and wars around the world ( http://www.baltimorechronicle.com/feb04_IceAge.html). Showing graphs that proved the natural periodic comings and goings of ice ages and interglacial warm times like the one we now live in, they pointed to dramatic climatic spikes that occurred when world temperatures rose to a certain level (http://www.freerepublic.com/forum/a3ab8599422eb.htm). These spikes caused the world climate to bounce between very cold and very warm, then disappeared as the planet went into another long ice age ( http://www.freerepublic.com/forum/a3ab8599422eb.htm).

Effects of Global Warming

Though it is difficult to connect specific weather events to global warming, an increase in global temperatures may in turn cause other changes, including glacial retreat and worldwide sea level rise ( http://en.wikipedia.org/wiki/Global_Warming). Changes in the amount and pattern of precipitation may result in flooding and drought (http://en.wikipedia.org/wiki/Global_Warming). There may also be changes in the frequency and intensity of extreme weather events (http://en.wikipedia.org/wiki/Global_Warming). Other effects may include changes in agricultural yields, reduced summer streamflows, species extinctions, and increases in the range of disease vectors (http://en.wikipedia.org/wiki/Global_Warming).

The Greenhouse effect

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface (http://en.wikipedia.org/wiki/Greenhouse_effect). The name comes from an incorrect analogy with the warming of air inside a greenhouse compared to the air outside the greenhouse (http://en.wikipedia.org/wiki/Greenhouse_effect). The Earth's average surface temperature of 15 °C is about 33 °C warmer than it would be without the greenhouse effect (http://en.wikipedia.org/wiki/Greenhouse_effect). The greenhouse effect was discovered by Joseph Fourier in 1824 and first investigated quantitatively by Svante Arrhenius in 1896 (http://en.wikipedia.org/wiki/Greenhouse_effect). Global warming, a recent warming of the Earth, is believed to be the result of increased concentrations of greenhous gases in the atmosphere (http://en.wikipedia.org/wiki/Greenhouse_effect). In addition to the Earth, Mars and Venus have greenhouse effects (http://en.wikipedia.org/wiki/Greenhouse_effect).

What causes Global Warming

Global Warming has alot to do with the change in our climate. The Earth's climate changes in response to external forcing, including variations in its orbit around the sun, volcanic eruptions, and atmospheric greenhouse gas concentrations (http://en.wikipedia.org/wiki/Global_Warming). The detailed causes of the recent warming remain an active field of research, but the scientific consensus identifies elevated levels of greenhouse gases due to human activity as the main influence (http://en.wikipedia.org/wiki/Global_Warming). This attribution is clearest for the most recent 50 years, for which the most detailed data are available (http://en.wikipedia.org/wiki/Global_Warming). In contrast to the scientific consensus that recent warming is mainly attributable to elevated levels of greenhouse gases, other hypotheses have been suggested to explain the observed increase in mean global temperature (http://en.wikipedia.org/wiki/Global_Warming). One such hypothesis proposes that warming may be the result of variations in solar activity (http://en.wikipedia.org/wiki/Global_Warming).

Hurricane cont..

A hurricane contain an eye that is at the center of the storm. The eye is a region of mostly calm weather found at the center of strong tropical cyclones (http://en.wikipedia.org/wiki/Eye_(cyclone)). The eye of a storm is a roughly circular area (http://en.wikipedia.org/wiki/Eye_(cyclone)). It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather of a cyclone occurs (http://en.wikipedia.org/wiki/Eye_(cyclone)). The cyclone's lowest barometric pressure occurs in the eye, and can be as much as 15% lower than the atmospheric pressure outside the storm (http://en.wikipedia.org/wiki/Eye_(cyclone)). In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall (http://en.wikipedia.org/wiki/Eye_(cyclone)).

Hurricane

A hurricane is also called a tropical cyclone. A tropical cyclone is a meteorological term for a storm system characterized by a low pressure system center and thunderstorms that produces strong wind and flooding rain (http://en.wikipedia.org/wiki/Tropical_cyclone). A tropical cyclone feeds on the heat released when moist air rises and the water vapor it contains condenses (http://en.wikipedia.org/wiki/Tropical_cyclone). While tropical cyclones can produce extremely powerful winds and torrential rain, they are also able to produce high waves and damaging storm surge (http://en.wikipedia.org/wiki/Tropical_cyclone). They develop over large bodies of warm water, and lose their strength if they move over land (http://en.wikipedia.org/wiki/Tropical_cyclone).

Tornado Myth cont..

Most tornado damage is due to the low pressure in the tornado causing the house to explode (http://en.wikipedia.org/wiki/Tornado_myths). Opening your windows or doors while a tornado approaches will equalize atmospheric pressure and help prevent property damage (http://en.wikipedia.org/wiki/Tornado_myths). Basically don't waste time opening opening any windows in your house. You could be doing soemthing better to prepare you for the worst. Windows can break very easily from flying objects.
