Okay! let's talk serious....
I think everyone here knew something about Global Warning. Some of my friends told me that the signs are coming. And the world is on the verge of Global Warning!

Let see some case:
1. In northern Thailand, top of the mountain, there were reports of Snows (A SNOW IN THAILAND!!!!!). Don't know is this true or false, perhaps someone could verify this....
2. During 1990, when i just a small kids recently arrive from Middle East, Bandung average temperatures were about 18-21 degrees Celcius (Pretty cool for Tropical Country in equator...). But nowaday, The temperature could rise from 17 degrees in morning to 36 degrees in the afternoon!!! Even at night the temperatures could drop very significant. Lot's of my friends got fever because they slept at 09.00 PM when the temperatures 32 degrees with only shorts and sarong, and at midnight it dropped to 18 degrees.
3. The sea water level were increasing from years. Now the seawater prespiration has reached middle city so wells there got salty water.

Anyone knows what cause these phenomenon? Any links or website or other cases?
 
First of all I think it's "Global Warming". At first I thought your post was a reference to President Bush's latest speech. I'm currently taking Geography 1010 and I can assure that in order for a signifigant amount of global warming to occur, we would still need a few more degrees of increase. Bear in mind that "Global Warming" is going on as we speak, but were still in what you might call the "safe zone". This would explain the increase in sea level; yes, Antarctica is melting, but at no life-threatening rate. Considering it takes an uncanny amount of time to raise 1 degree, we're OK for a few more years. As for the funky weather in the Middle East, clouds have a lot to do with weather. If there are no clouds at night, they can't trap the warm air in, leading to one very chilly slumber. Still learning a lot, but that's what I know...

[font size=1" color="#FF0000]LAST EDITED ON Feb-07-03 AT 03:48AM (GMT)[p]Its a definite probability that there is global warming happening now. The trend is pointing in that direction. It already is leading to some crazy weather in many parts of the world and is going to cause alot of problems in the near future. The biggest problems are going to be rising sea levels, freshwater availability, and droughts. Not a good combination and it will lead to a lot of dying and war.

Now some people are blaming the problems on civilization and they may be partially right. But the planet has a history of swinging through climate changes and nobody really knows what those cycles are. A few crackpots say it is a continuous trend which will lead to the end of the world. I find that hard to believe considering some of the major catastrophes that have happened in the past. Some of the asteroids that have hit this planet in the past must have caused a hell of a lot more damage than you could have imagined. Major climate cycles can last for several hundred or even thousand years. Look at the ice age for example. At worst the global warming will wipe out most of the population and we'll have to scale back for a few hundred or more years. So the moral of the story is live in mountainous areas where you have access to plenty of freshwater and space for farmlands and you should be alright.

Well if you are going to talk about disasters like astroids then there is good probability that the atmosphere we have now is not the first in the history of earth. There is good chance that our atmosphere has been blown off by really signifficant meteor strikes in the past.

Offcourse this has not happened in a couple million years at least(billion actually I think).... but that is what a really signifficant meteor strike could do. The one that wiped out the dinosaurs was just a baby.
thankfully our solar system is now pretty much finished forming so such meteors are not as likely since the planets have absorbed them over time.

As far as global warming is concerned then we are not likely to see the results of our actions now for a couple of decades at least. For example there are underwater jet streams in the oceans which are caused by a number of factors. I am sure this is not new to many of you. My point however is that there are jet streams that are formed when water is heated and evaporated in the equator and therefore the salt content rises and the water gets heavy and falls in columns to the bottom taking the heat with it. It then travels along the bottom for decades finally reaching cooler limates in the north and south. this effectively transfers huge ammounts of enrgy to heat the north and south. In the cooler climates surface water is very cold and therefore also heavy and falls to the bottom creating cold jet streams which reach the equator. This exchange of enrgy is apparently now being disrupted as the poles get warmer and the equator is experiencing more temperature shifts. The influx of huge ammounts of fresh water from the melting poles is also having effect on this system. However we will not see the results of this for decades because of how slow this system is.
Saying our planet goes through swings in climate is really not saying much because the issue is how we will affect the extremes of these swings and what kind of new equilibrium will be reached in the end.

I saw a program on this not long ago. I think I got the general idea right though I know I have missed important details. The reason I mention this at all is because I want to point out how slow some of the ecological processes are and how our actions today may not have evident repricussions for decades, if in our own lifetimes at all.

You're from the Middle East? Which country?

People fail to look at the long-term. Sure the Earth may be warming up, but who's to say that isn't just a long term climatic change that occurs in cycles beyond our recent recorded history. Even in the late 1800s there were periods of very warm seasons and drought, only to be met with very wet ones after that. The hole in the ozone layer at the south pole has drawn so much attention for growing larger but long-term measurements have shown that it swells and shrinks continuously.

Volcanos, underwater methane deposits, forest fires and all kinds of natural "disasters" have spewed FAR more pollutants into the air in recent history than probably the whole of humanity has in its history. Such events have had dramatic short-term effects on the global climate but none of those effects have been permanent.

Even a full-scale nuclear war would not leave the planet in a permanent lurch. The Earth would return to its relatively normal state in a decade or so.

Only really large scale effects could cause us "permanent harm." For example if the salt flow at the bottom of the Atlantic Ocean were disturbed. If it stopped flowing, the natural heating effect of the ocean might send the Earth into an temporary ice age while it sychronizes itself again. The only reason we should worry about global warming is that maybe it could accelerate such processes. More often than not however, the Earth will follow its cycles irrespective of what we do.

Nahhh!!! I'm Indonesian. But i stay 5 years in Syria. My dad was a diplomat.
Oh yeah anyone knows what cause the long winter in Europe and unstable seasons in SE Asia? I mean, someday in the middle of January we got drought and Sometimes we got flooded next day. It unpredictable. Something wrong with our earth!
 
The winters keep getting shorter and dryer every year where I live, but like Xotor said we can't really say what makes this happen.
 
How's the Climate back in Mid East Anyway?
Well it's 13 years ago and Syria and Yordania got a nice weather. Saudi a bit hot and Egypt even hotter (no need to boil water!).
So the winter become longer ey? Right we never know when the drought started and when the rainy season! Yeah FUBAR. And i got no time to repair my roof. Its leaking everyday (sigh!).

Anyway i once heard that the earth climate is about to change. I dont know somekind of Orbital shift or something. And i heard this always happened in million years cycle.

I know they are used to blame everything on, but it is probably from the global el Niño/la Niña effect. It, in effect, reverses the normal patterns of weather in the world, or at least in the near-Pacific zones. The monsoons were shifted, summers and winters were more mild, and everything was thrown into chaos. The world is still suffering from the effects.

Here, in the Western USA, or at least where I am, it has been in a drought for four to five years, whereas in the East it has been exceptionally wet.

People think that their weather is really bizarre now, but that's only because they can't remember other times and incidents. These effects that skip decades should be of no worry for us since it is such a short amount of time. Even century-long trends don't say much since the Earth goes through cold/hot/wet/dry cycles all the time.

[updated:LAST EDITED ON Feb-15-03 AT 02:41PM (GMT)]in scandinavia the winter comes and goes and it doesn't rain much which is kinda unusual...Usually the winter remains for a couple of months but know it comes and goes about every 2nd to 3rd week (has so far at least(at least where i live))I think it did that last year as well, but i wasnt here the whole last winter so im not certain
 
In Brazil,here,about 13:00 its raining and 13:30 its very sunny and hot,then,at 15:00 rains again and makes very much cold,then becomes sunny again,it already snowing at some points here,a few months ago it was 46º degrees,and right now(12:50)it is 25º degrees,a few hours ago it was 17º,and i have sure that it will be about 30 degrees about 15:00.
That's very strange,a lot of things are different,thats very hard,soon we will have to move to another planet.
 
They've actually found that the temperature of the planet has fluctuated naturally throughout history. I mean, there was that whole ice age thing... So either way, we're probably going to have temperature issues in the future.
