have you heard of global "darkening"? this is the reason why climate has been changing..?

I watched a show on the history channel last night and it talked about "darkening" From what I heard it still balances nature. The program said without "darkening" the "global warming" rate would increase 5-10 fold. The whole concept is interesting but I'd need to hear more.\n\nJason

Actually we are going for Global Warming, where all teh Ice is going to melt and probably flood alot of places, the atmosphere is gettinng thinner and more ultra violates are entering earth. P.S. did you see any Acorns? Keep looking for it...

We are already seeing the effects. Read Bright Dawn, dark future  it was published in the early 90s but predict several events that have happened since do to GLOBAL WARMING!!!

global dimming is a very worrisome factor. By the turn of the next century we will have more dimwits than at any other time in the history of mankind. Already this phenomenon has become a global concern. So many people's brains are dimming.

Yes, global warming has started and finished and started and finished.\n\nThe earth has been much warmer before and much colder.  It will be both much warmer and much colder again many times.

well, scientists and meteorologists theorise that because of global warming, the ocean's waters are getting warmer and causing more hurricanes and tropical storms to spawn. also, the earth is the warmest it's been in over 2000 years. all you need to know, WE BEAT THE RECORD! :P

Read the article below and you start to understand how variable earth's climate has been and more than likely will continue being.\n\n\n\n\n\n\nClimatologists have used various techniques and evidence to reconstruct a history of the Earth's past climate. From this data they have found that during most of the Earth's history global temperatures were probably 8 to 15° Celsius warmer than today. In the last billion years of climatic history, warmer conditions were broken by glacial periods starting at 925, 800, 680, 450, 330, and 2 million years before present.\n\nThe period from 2,000,000 - 14,000 B.P. (before present) is known as the Pleistocene or Ice Age. During this period, large glacial ice sheets covered much of North America, Europe, and Asia for extended periods of time. The extent of the glacier ice during the Pleistocene was not static. The Pleistocene had periods when the glacier retreated (interglacial) because of warmer temperatures and advanced because of colder temperatures (glacial). During the coldest periods of the Ice Age, average global temperatures were probably 4 - 5° Celsius colder than they are today.\n\nThe most recent glacial retreat is still going on. We call the temporal period of this retreat the Holocene epoch. This warming of the Earth and subsequent glacial retreat began about 14,000 years ago (12,000 BC). The warming was shortly interrupted by a sudden cooling, known as the Younger-Dryas, at about 10,000 - 8500 BC. Scientists speculate that this cooling may have been caused by the release of fresh water trapped behind ice on North America into the North Atlantic Ocean. The release altered vertical currents in the ocean which exchange heat energy with the atmosphere. The warming resumed by 8500 BC. By 5000 to 3000 BC average global temperatures reached their maximum level during the Holocene and were 1 to 2° Celsius warmer than they are today. Climatologists call this period the Climatic Optimum. During the climatic optimum many of the Earth's great ancient civilizations began and flourished. In Africa, the Nile River had three times its present volume, indicating a much larger tropical region.\n\nFrom 3000 to 2000 BC a cooling trend occurred. This cooling caused large drops in sea-level and the emergence of many islands (Bahamas) and coastal areas that are still above sea-level today. A short warming trend took place from 2000 to 1500 BC, followed once again by colder conditions. Colder temperatures from 1500 - 750 BC caused renewed ice growth in continental glaciers and alpine glaciers, and a sea-level drop of between 2 to 3 meters below present day levels.\n\nThe period from 750 BC - 900 AD saw warming up to 150 BC. Temperatures, however, did not get as warm as the Climatic Optimum. During the time of Roman Empire (150 BC - 300 AD) a cooling began that lasted until about 900 AD. At its height, the cooling caused the Nile River (829 AD) and the Black Sea (800-801 AD) to freeze.\n\nThe period 900 - 1200 AD has been called the Little Climatic Optimum. It represents the warmest climate since the Climatic Optimum. During this period, the Vikings established settlements on Greenland and Iceland. The snow line in the Rocky Mountains was about 370 meters above current levels. A period of cool and more extreme weather followed the Little Climatic Optimum. A great drought in the American southwest occurred between 1276 and 1299. There are records of floods, great droughts and extreme seasonal climate fluctuations up to the 1400s.\n\nFrom 1550 to 1850 AD global temperatures were at their coldest since the beginning of the Holocene. Scientists call this period the Little Ice Age. During the Little Ice Age, the average annual temperature of the Northern Hemisphere was about 1.0 degree Celsius lower than today. During the period 1580 to 1600, the western United States experienced one of its longest and most severe droughts in the last 500 years. Cold weather in Iceland from 1753 and 1759 c

Well Global warming is a great threat, it is damaging planet earth. I was reading in this physics book about the effects of global warming and it stated that the rising levels of harmful chemical gases in the earth's atmosphere could damage the earth forever. It says the with the build up of sulphur dioxide, nitrogen, methane, ammonia and carbon dioxide in the earth's atmosphere, a giant chemical ring will form around the earth's atmosphere blocking sunlight coming into earth, so therefore the earth turns into "lo" one of jupiter's many moons. I'm not saying that this is true, but that's what i read in my book.

The ozone layer is thining through incresed pollutio by planes brought about by a peak in flyers, green house emissions, increased industrial pollution, forest degradation. all these allow more UV light penetration into earth and will continue to increase unless we stop polluting the environement.:(

Many scientists believe that we are actually heading toward a global ice-age as opposed to a global warming.  \n\nAlthough a work of FICTION Michael Crichton's "State of Fear" provides evidence to support this.\n\nI suggest reading it (it's FIRST AND FOREMOST a good FICTION book, but is supported by genuine theories and statistics that ARE IN FACT from "Science" and "Nature" magazines, the worlds fore-most scientific mags)\n\nTo be honest I don't think we're experiencing anything unnatural about our environment right now.

Not really but in fact the bigger problem is not CO2 but CO. Never the less you know that CO2 levels have suffer a cycle since the beginning earth however since the Industrial revolution they climbed hugely the climate has already changed. At least in my part of the planet it is hotter generally I notice it, my parents did and my friends in general, but it is the older people that notice it the most. The climate is cyclic, sometimes it makes things from 100 to 100 years and at the beginning one thought it might be that but it’s not it’s really a matter of global warming. (I am portuguese to now more about the fire in summer consult the web or see it in CNN in the summer), it is real and it is now

that's only true in the northern hemisphere. it's because moss likes shade, and the north side of anything in the northern hemisphere is the shady side

this is all about global warming and if it actually is occurring. yes if it is happening Hawaii would indeed be covered(i think, not 100% sure) but does it exist? in my opinion is it doesn't exist. because think about it we are coming out of an ice age. it makes sense doesn't it? fact: there have been ice ages. fact: there is a lot of ice in ice ages. so if you know about water then you know the same amount of it is here that was here when the earth began so literally it is dinosaurs piss. well during an ice age lots of stuff is covered in water/ice ( i know i live in Minnesota and it is known that it was fully covered with ice.). so where is all the water? in ice bergs, glaciers, etc. so it would make sense that to leave an ice age most things would melt right? so they are still melting they will finish melting and cover parts of the world, then it will slowly freeze causing an ice age. why would humans make that big of a difference? we are insignificant to the world.(everyone in the world could fit in Texas and it would only be as densely populated as NY city). so our vehicles and combustible engines couldn't have that big of an effect. but you say "what about the ozone thinning?" well i am not saying it hasn't but it was because of the CF C's(chloral floral carbons) which broke up the ozone by attaching to ozone molecules. but the CF C's are no longer around. the ozone is healing itself as it is meant too. their was no real hole only a thinning which is also bad. but now it is closing up and returning to normal. if you think that the co2 we produced cant be good well think about it it isn't that much and while the earth was cooling after being created it released tons of co2. so what people will notice in the next 1-9000 years is it will warm up but in that time it will also cool down and eventually there will be an ice age. just because the great human race is here doesn't mean that the earth will stop having ice ages as it has done by its self for billions of years. think about it. am i a genius or what i mean i just looked at what has happened in history wow who would have thought history would repeat its self

I have to believe that we are on a downward spiral. We are depleting the primeval rain forests which provide oxygen and burning fossil ie carbon fuels which produce carbon monoxide and carbon dioxide, in addition to excreting sulphur which produces sulphurous and sulphuric acid. The westernised/civilised world is reluctantly taking small steps, but the 3rd world is increasing at an alarming rate.\nGlobal warming is a fact, and the result of this within this century will be frightening both in terms of sea-level rises and also hurricanes/typhoons/cyclones. Let us see what damage is caused in the Gulf of Mexico THIS year....

I have been wondering if I would see a global warming question up here.  I thought for sure there would just be a bunch of answer blaming Bush for it.  I am glad to see it hasn't gone that way yet.\n\nThis whole global warming thing is a complete sham.  When I was in school they used to run stories on global cooling, we were all going to be under ice, because all the air pollution was going to block out the sun.  Now its global warming, just more nonsense.\n\nUnfortunately they don't teach you kids much in school nowadays.  The Earth goes through climate changes ALL THE TIME.  I know you have all heard of ice ages, probably only because of the cute little kids movie, but we have had them its really true.  It has also been really, really hot here.  We have been completely covered by ice, we have been without even ice at the poles.  The poles themselves actually flip from time to time.  One day the north pole will be the south pole, it has happened before and it will happen again.\n\nWe can't even come close to attempting to try to affect the climate.  And nothing we can do, can stop, or alter where the climate is going.  If it does in fact get warmer, we didn't do it, and we can't stop it.\n\nYou really need to understand what is behind things like this though, because it is truely unAmerican.   A large part of the world and more unfortunately a small but significant percentage of our own people, simply believe we do not deserve to be the world most powerful country.  And everything they can do, to level the playing field, they will do.  This is simply one of those devices.  There are plenty and there will be more.

in ten years i think the major change will be that global warming is universally accepted because the climate will become more unstable.  The better name for global warming is climate change because, while the overall temperature of the earth is rising (ever so slightly) the key indication/affect is changes in climate (which includes differences in storm activity from the recent past).\n\nBut basically, yeah the huricanes and wind storms and early and late and heavy and light seasons will become more noticable, even in 10 years.
