Why changing weather all in the world.?

Climate is variable. Always has been. The question is, is there currently an anthropogenic component to the variation?

El Nino.  It really is fascinating because there are long periods where the weather has changed and caused civilizations to crumble in the past.  It kinda puts into perspective how dependent we are on our climate.\n\nhttp://www.elnino.noaa.gov/\nhttp://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/eln/home.rxml\nhttp://www.pmel.noaa.gov/tao/elnino/el-nino-story.html\nhttp://www.pmel.noaa.gov/tao/elnino/nino-home.html\nhttp://www.coaps.fsu.edu/lib/elninobib/\nhttp://www.eurekalert.org/pub_releases/2001-06/UoM-EfEN-1706101.php\nhttp://www.umaine.edu/news/Archives/2001/June01/elnino.htm

Probably just the weather changing quickly ? We had a thunderstorm a few weeks ago, except it was snowing with it. Really warm before it and really cold afterwards... I'm sure it's nothing to alarm yourself over.

Actually, the Earth does move ever so slightly closer and farther from the sun at different times of the year. However, this is not what causes the change in temperature. The change in temperature is mainly caused by the tilt of the earth towards or away from the sun. So, for us in the Northern Hemisphere....during the winter, the northern axis of the earth is tilted slightly away from the sun. This means that the suns rays during the day are less direct on this part of the world. It's also why the sun seems to always be in your eyes during winter driving. It never rises far above the horizon.

because every day more water vapors and more rain comes so the weight may vary!!

The weather is unpredictable everywhere!

I do not understand your question. If the climate warms, then surely it will change. \n\n\nIf there is a bigger difference between the cold areas and the warm areas on the planet, storms might be more violent, and there might be more variability in the weather.

Global warming is definately here! Just take a look at all the weird weather going on. First, the number of hurricanes and tornadoes is getting higher and higher each year and not only that but they are becoming stronger. Hurricanes are gaining intensity each year and tornadoes are becoming a very frequent thing where I live. The reason the hurricanes and tornadoes are becoming more and more frequent is because any time you add heat to a tornado or hurricane they gain strength. You can see that global warming is here because the ocean waters are getting warmer, causing sea levels to rise from melting poles and because of this category 2 and 3 hurricanes are almost non existant. They are all at least category fours. Hope that helped!

Changes in barometric pressure do cause changes in both human and animal behavior. Ask any veteran teacher...they can tell a lot about how the day will go just by the weather that morning...

I think you are talking about the 'Butterfly Effect' in weather forecasting.   With all the wonderful computers they have to help to forecast the weater, one of the staff was sitting in his garden when a butterfly flew past him.  He suddenly realised that the air movement caused by the wings can cause air movement which can increase over time, enough to cause a major storm in another part of the world.....................

It's much warmer now, all over the world, due to Global Warming...(other signs: earlier arrival of spring, heat waves, spreading of disease, etc.) Check out this web site below.

Well, the weather changes very quickly, however global warming has been happening for a while. It is in the past while predicting the weather is in the future. There is data that shows a warming trend on Earth. So, you can trust it, at least as fact that is IS happening. Most people agree on that. However nobody is sure whether or not this heating is natural or caused by humans.

actually, because of Global Warming, we would be in the ice age.  The increase in temperature causes a higher density of water vapor in the air, as a result the net temperature on the surface of the earth drops, and we get lots and lots of percipitation.  The Earth is making drastic attempts to shift it's self to remedy this.  Al Gore thinks we can control it because WE caused it, and so it would stand to reason that we fix it.

You have to constantly change your clothes to adapt to the weather.This ultimately affects your life.

changes in air pressure, and temperature at changing locations

Climate exists because weather is dominated by several quasi-permanent weather systems (including a high-pressure over Bermuda which oscillates and low pressures near the poles).  These weather systems do not move much (except for annual oscillations), so weather patterns will emerge from this quasi-stationary setup, and hence we have climates.

We have rain and thunder/lightning, earthquakes, volcanoes erupting, epidemics, famines, droughts and all sort of world disasters. =)
