There is some evidence that there have been drastic and slower changes in weather patterns throughout our planet's history. It does seem as though we have had an undue influence on the atmosphere and weather changes in the last hundred years, and that is leading to more drastic changes in weather patterns.

One morning a FOX News journalist was reading an excerpt from a book written by a scientist in the mid to late 1800s. This information was pertaining to the global warming and the melting of the polar ice cap (or whatever term they used then). The information very closely resembled the information scientists discuss with regard to those issues today. This would indicate that weather patterns and trends have a tendency to by cyclical.

Climatologists have reported changes in the position of the jet streams which are responsible for driving our weather across the states. Recent studies show the jet streams moving towards the poles in both the northern and southern hemispheres. This causes a shift in weather patterns.

The most noticeable change in the past century is the rise in temperature, and the climate shifts associated with that.  Scientists and climatologists have measured average surface temperature of the Earth for decades, and have noticed a 1.2 degree increase (Fahrenheit) in approximately the last 50 years.  We are also starting to see shifts in precipitation patterns, such as longer periods of drought and increased amounts of precipitation falling at once.  It's also worth noting that 9 of the 10 hottest years on record occurred in the last decade.

Changes are taking place in past decades, and gradually, weather is becoming hotter. Deforestation is causing heightened temperature, and accordingly, green house effect, one of the most talked about topics in the present world, is making all creatures on the Earth reach the verge of extinction slowly. Mainly the rapid change of the weather especially regarding the temperature will soon be a cause of destruction of human race along with other animals on the Earth. That's why natural disasters like Tsunami, Aila, and Sidr are taking places especially in the coastal areas.

 Climate change affects us all , globally. Although this may seem insignificant at first glance, their effects on everyday life can become very serious. It is thought that climate change will lead to further sea level rise that will threaten coastal areas in the world by erosion and flooding. They will also determine increased frequency of extreme weather events and rainfall patterns change on a global scale, leading to floods and droughts.
