Difficult global warming problem?

I don't know; that's a dilly of a noodle-scratcher! Hmmm let's see... I would say 10%.

I'm pretty afraid.  I don't know where we're headed economically, politically, environmentally, anything...and I'm not even sure what will be the biggest problem first.  For instance, it's relatively clear that climate change will be an issue, but when?  And is it even possible at this point for us to turn some of these things around?

It is indeed a threat...But so is global warming....have you noticed the weird weather lately?

I guess I am not allowed to answer since I am concerned about global warming.  I am also concerned about the massive population explosion of dim wits.  Both are great causes of concern.  But since you did not ask for solutions I will not give you what you did not ask for.  You seek to get blabble babble static and drivle...

>>> info saying global warming is not a big deal.\n>>> I got stuck on the side saying global warming does not\n>>> exist.\n\nHang on, are you arguing that it doesn't exist, or are you arguing that it's not a big deal? Those are two totally seperate arguments with no relationship to one another.\n\nIf you are arguing that it's not a big deal then I second the recommendation of Lomborg. \n\nIf you are arguing that it doesn't exist then Lomborg is worthless since he is one of the most vocal supporters of global wamring the world has ever seen. Lomborg is quite convinced that it exists and goes to lengths to convince others that it exists. He just doesn't  see it  as a catastrophe.\n\nAs you can see these are two totally separate issues, and you really need to tie down what you mean before you can even start your research.\n\nIf you really are attempting to argue that global warming does not exist you have an uphill battle.  AFAIK all scientists accept that it exists. The only argument is how much of it is caused by humans and what the efcets will be. You are really knobbled if you have to arguee against the entire scientific community. I can't believe your teacher would set this up.\n\nBut if that is the case then you are really restricted to a few essentially crank websites. I've provided a link to one of the best ones out there, but it's still not terribly scientific or accurate.\n\nGood luck and return if you need more help. And you're gonna need if you are arguing that global warming doesn't exist.

No.  If the planet were on a cooling trend, and stayed that way for a while, it might be heading towards a periodic Ice Age, as it has done in the past.  We would consume a lot more of outr limited energy resources just to keep ourselves warm.  Also, don't worry so much about Global Warming.  As I said before, nature goes through these cycles of warming and cooling.  Yes. humans have an impact, but it is small.

Blame it on global warming.

Science explains Global warming. More storms, bigger storms, carbin dioxide levels, soon crops may burn up before they grow, rain forest desease may spread, Gulf stream may stop, In Our Lifetime.\nIs a good read, go see... Times ARE changing.

Consider this: We were in an ice age within the past 10,000 years. The ice from this ice age covered most of the northern hemisphere; not so much of the southern hemisphere, but a little. Since that time, glaciers have been retreating, the planet has been warming, and the oceans have been rising steadily. The vast majority of the "problems" are a continuation of the return of the earth from the ice age. \nSince the industrial revolution, humans have been emitting certain gases into the air that come from fossil fuels. These gases go into a layer in the atmosphere that traps heat. This layer was in existence before the revolution, but now is being thickened.\n\nSo, with all this said, I believe that the majority of the global warming problems are just us coming off of an ice age. however, we humans aren't helping by emitting the gases.

right now  we have a trouble with our climate  is 3 big problems  from the last 5 years  we (humans )1.- in the whole world  destroy  forest and nature this contributes to the world warming  a lot\n2.- the sun activity is on a rise (so explode more continuously and flares are more bigger and hot) the sun activity  going down and up each 20/30 years  you can check it out for more information in wwww.nasa.gov or www.spaceweather.com\n3.- for many years the spray cans  , fuel in cars,  energy production with atomic energy, and fridge gas and many other substances made  by the man destroy the ozone layer and big holes in the pole  contributes to the warming to so in the next years  we got big tornadoes , very hot temperatures in spring and summer  the ice in the poles are melting now  and the seas going up soon with more water , next years many big problems with nature is coming , like hurricanes more bigger and Strong's , winters more cold with more snow and many other things\nand even the earth core get transformations we can help to restore some  if we plantting more trees if we use less oil, gasoline, and spray paint or other applications that come canned

Start with Al Gore's Inconvieniant Truth to get the big picture. Then if you can consider other people elsewhere besides where you live you would know they are being effected right now. The world is warming up and ice is melting everywhere. We should all be very concerned......

It's hard to predict a date that we will all die, but problems are already happening.\n\nCO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.\n\nLook at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest.\n(see links below)\n\nHow's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.\n\nThere has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.\n\nYes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up. \n\nJust to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.\n\nHI CO2: \nhttp://news.bbc.co.uk/1/hi/sci/tech/4467420.stm\nHOCKEY STICK: \nhttp://news.bbc.co.uk/1/hi/sci/tech/5109188.stm\nGeneral climate stuff: \nhttp://news.bbc.co.uk/1/hi/sci/tech/3897061.stm

talk about global warming\nits a huge topic that will be more than enough to fill up 10 pgs\ntheres a lot to be researched too, so prepare for lots of work\nstuff like causes, preventions, consequences, proof\nresearch into Kyoto Accord, greenhouse gases, ocean currents, recent appearances of hurricanes (hurricanes build on warm air, and the temperature has been rising in the past few decades), car emissions, melting ice caps, change in migration of animals, stuff like that

honestly global warming is a big f'n lie. If anyone knew anything about meterological weather history, they would know this "overall world warm up" happens all the time, along with the "overall world cool down" if you knew anything about science in that area, you probably wouldnt be a crazy liberal. PS, driving a enviornlementaly friendly car isnt going to do squat.

I do agree,they claim el nino is responsible,some claim global warming. The semi cold weather with wet,cloudy days is depressing not to mention it brings on aches and pains......Illness The cold snowy days seem to bring excitement, to cold for the germs. My personal theory is the whole Earth has shifted orbit just enough to mess the weather up. Scientifically I would go with global warming or the green house effect. We have used and released so much freon or R-12 into the atmosphere, plus other pollutants its really damaged are enviorment all for comfort. Maybe we should go back to horse and buggies..lol

Is the book you read "State of Fear"?\n\nYou can debate this all you want, but you wont get anywhere until you define 'global warming.'  I think I wrote a long-winded explanation in another answer, so search for that.\n\nThe long and the short of it is:\n\n1.  The Earth goes through natural warming and cooling, based on a HUGE range of varying natural processes, from changes in orbital paramaters to changes in sea ice thickness in polar regions.  It has done this since there were oceans and an atmosphere, and will always continue.\n\n2.  Humans have influenced certain properties of the atmosphere and hydrosphere that may be contributing to accelerated warming (ozone depletion, increased levels of 'greenhouse' gases, etc).  Since we dont know if the Earth would be warming anyway, we cant definitively say that a current warming trend is related to human influence (but its a good bet).\n\n3.  Global warming trends are difficult to understand.  As a paleoclimatologist, I dont even understand it.  I dont know where the temperature data has been collected, the spatial distribution of the data points, I dont know what the temperatures are being compared to (the Earth has been much warmer at times in the past), I dont know if the scientists who tabulate the data are being influenced by something other than true science, etc.\n\nBottom line is that its a VERY VERY complex problem.  Unfortunately, the more data that are generated, the more complex and vague the answer will become, and the more people will become divided over the interpretation of the data.\n\nIt would be wise to minimize our impact on the climate system (or any Earth system for that matter) as best we can, no matter what the answer is.  The more interesting question is: when will the next 'ice age' begin, if it hasnt already?!?!?

It is Global Warming.  Geologically speaking we are still coming out of the last ice age.  We are on in a natural cycle which has been accerated by pollution.
