How real is global warming?

Agreed. Global Warming in the normal sense is BS. it's just another phase of our planet - I'm sure it's happened millions of times before.
I tend to agree.
However, I think it is naive to believe that everything we spew into the atmosphere has absolutely no effect. Nature thrives on balance, and something has to happen to correct any balance we've upset.
So basically, we don't know. We haven't been keeping records of large enough time frame to even begin to grasp it.
The world is heating up, that part is pretty clear.
What is not clear is why.
Personally I think trying to control the environment is foolish, just more of man thinking he is able to control the elements.
We'd be better off finding ways to adapt to the warming trend, and spend more $$$ on space missions. Off-planet colonies are humanity's only chance for long-term survival.

Yeah..I mean our dependency on cars, oil, anda ll that has to be doing something. What do studies say about how great the effect is though?
I doubt anybody has any REAL answers to this. I don't see how we could accurately measure this. I think it's all speculation
Oh, I think the warming part is quite real. Most scientists are in agreement about that. The question that remains is why?
BTW, I also think that while, yes, the Earth's climate is cyclical, and yes, the Earth is largely self healing, it is absolutely foolish to believe that all the stuff we've been burning for the past couple centuries, and especially in the last 100 years, cannot have any effect on the planet.

Yep, exactly.
There is no doubt the Earth is warming. We just don't know why.
Eh? El-Nino is a real phenomenon. It is an abnormal heating of the water in the Pacific. The opposite is called La-Nina; an abnormal cooling.
They both cause abnormal weather patterns. It's actually quite fascinating.
I don't think we're technically still in it. If we are, we're at the very tail end of it. The ice has been melting for the last 10,000 - 20,000 years or so.
Like I said, we don't have accurate records for a large enough time frame to really know. We only have semi-accurate weather records for the last 100 years or so. We can "see" into the past due to geologic records, but the margin of error is too great and we don't know enough of the specifics to really come to any concrete conclusions.
Right, but I don't believe that it's having a HUGE effect. Soon we'll be able to cease using fossil fuels so it won't be an issue.
The earth has natural Warming and Cooling trends, where the average overal temperature of the Earth fluctuates between something like +4° and -4° Celcius. -4° would mean an Ice age.. Imagine, 20-30 feet of snow year round in Florida.. +4° Would mean melting of the polar ice caps and flooding of much of the planet.. Say good by to most of the Earths land.. not to mention any coastal city..
These changes happen over billions of years, and do not always go to the extremes..
Right now were on a natural upwards trend.. So very slowly over time, the overall average temperature will continue to rise, albeit, very slowly.. But the huge amouts of pollution we throw in the air, creating a 'blanket', is only helping to accelerate the rising average temperature.

I dunno about that. "Soon" as in the next 50 - 100 years, maybe.
The Internal Combustion Engine isn't just going to keel over dead.There is no doubt that the CO2 concentrations in the atmosphere have risen dramatically in the last century. We can see that.
But the effect it has on weather is largely unknown. It is far too complex to understand, let alone if it is changing. We can barely predict the weather accurately within a 24 hour time frame. Even then, oftentimes it does something completely different than even the best computer models show.
Why do I get an overwhelming feeling that lots of people commenting actually have no real knowledge on what they are talking about in regards to global warming.
Im no real expert on this.. But couldnt it be something as simple as fluctuations in the Earths orbit? (As to what causes them, thats another question).
Again, im not sure on the numbers.. but imagine the temperature change if the Earth was a million miles closer to the sun, or a million miles away. Something like taht would make a HUGE difference here on the ground
I think the average temperature of the oceans have risen almost 1C in the last hundred years or so. Maybe it was 0.74C or something like that, don't really remember. Regardless, it is quite significant on a global scale.
I don't think the Earth's orbit changes.Originally posted by: DaZ

It would throw everything out of wack, it seems.....Originally posted by: DaZ

The rise in temperature has occured far too fast to be a fluctuation in the Earths orbit according to most scientists.

Long-term global temperature fluctuation is normal and well-documented even in relatively recent human history (the 1200s were very warm for example, while the 1300s were very cold). The 1800s into the mid-1900s were quite cold, relative to recorded history. Now we are warming up a bit. It's normal.
I read an article recently that said that while the earth is warming up, it's getting greener. More green plants = more CO2 turned into O2 = climate cools again. It's just part of the earth's normal cycle. The sky is not falling. The earth existed before us, and it will exist after us.
