Even if global warming were totally man's fault, wouldn't the changes required to stop the warming essentially require far more sacrifice then even most so-called "green" people would be willing to make? I man caused this, it's too late to fix it. I see no need to trade my Wrangler for a Prius.

warming of the globe on an average, saying "well it was a cold winter in Albuquerque last year" is not a global average since as we've seen & why people are using the term climate change instead is because the weather doesn't just stay the same only get warmer; everything interacts w/ everything else, weather gets more extreme in general. an example would be rain forests, more heat can make them flourish; but you go past a certain point and instead of absorbing co2 they start releasing it (yes plants can release co2, they both respirate and photosynthesize); water stress, change in soil conditions, heat, humidity (or lack of); all these things can effect it. It was well documented in the 2003 European heatwave

To add to that we understand what causes natural climate change fairly well, but all the usual natural triggers are absent. It's a bit like finding a dead body. First you look for natural causes as to why the person may have deceased, if you cannot find any natural causes police usually begins to suspect foul play and launches a deeper criminal investigation.
In climate science too first the warming trend was discovered (the body) then a search for possible natural causes. Orbital variations are not at play as we learned from Astronomers. There is no measured increase in Solar irradiation which correlates with the warming trend either. There don't seem to be any natural factors as known so far which could adequately explain the current trend. There is this myth out there that in the past 40 years not a single climatologist ever had investigated the sun. Needless to say this myth is often proliferated by those who have never even read the abstract of a single peer reviewed climate paper. Could there be a yet undiscovered natural cause? Certainly, but right now our best information says natural causes can mostly be ruled out.
Greenhouse gases however don't care how they're emitted they'll absorb heat regardless of their source. It's basic physics. The climate is very complex, with many factors influencing each other. An increase in a single variable, such as co2 may trigger other effects, like the amount of wator vapor in the atmosphere which adds to the warming. Reduced ice coverage reduces the planet's albedo, increasing the warming etc. This is as basic as I can make it.

Are we 100% sure? No, science is never 100% sure about anything. We can only approach the truth asymptotically. That doesn't mean however science is always wrong or is never reliable. Newton's laws still hold up pretty well in day to day life. I hear Heliocentrism is still popular too

If you have a problem with cap and trade or carbon taxes, take it up with your politicians, not the scientists.

The Earth does warm up on it's own, However we have contributed to the warming. The Amount of junk we emmit is Amazing.

The fact of the matter is that we don't have enough recorded data to accurately say anything is out of the normal.
And by "we do not have enough information" you mean "I haven't bothered to read the enormous amounts of information out there but I'm still going to hold onto my unsubstantiated beliefs", right?

Too late. And politics is intrinsically tied to global warming, since political decisions are the only real way to combat it.

So if you can honestly tell me anyone can predict that with just 150 years worth of data can accurately tell you what this planets cycles are then you're sorely mistaken.

I'll play along and for a second and let's just say they can. If that's the case then why are the weathermen not 100% accurate everytime. Oh wait that's because the weather can't be predicted perfectly yet. So what makes you think they can say that global warming that's caused by humans even exists?
Weather != Climate.

The earth has both heating and cooling cycles. We're actually in a cooling cycle right now. These cycles take hundreds if not thousands or even hundred of thousands of years to do one cycle. To say that the human race has a significant effect on this is very suspect.
Source? And if the earth is in a cooling cycle but is warming instead, does that not tell you something?

Also to go on the lines of the greenhouse effect. You do realize that there were 100% more carbon dioxide in the atmosphere when then dinosaurs were around. Studies have show that more carbon in the atmosphere leads to exploding population rates in both insects and animals. Along with that creatures generally become much larger as well.

There also is not enough data to say that Mankind's industry is causing the Earth to heat up. The Earth is warming though.

But I still don't care.
There is more than enough data to prove anthropogenic effects. They exist whether you have read them or not.

And what would it take to make you care? Humans are generally so short-sighted and apathetic to global, long term problems that we might not even solve this.

it may be coming some years later or sooner. Anyway, no humans will be here to check that up.

i really don't care.

The only thing that's confirmed, is that you gonna die.
Ignorant posts like this are really depressing.

Sigh. Natural effects are well understood and documented, and they do not account for the total current warming effect.

Global Warming =/= climate change.

Global Warming is a buzzword that basically blames all the world's climate change on humans. Climate Change is a natural process of the Earth, HOWEVER, we are accelerating it. We are neither solely responsible, nor irresponsible for climate change.

If we as humans were not here, the earth would still be changing.

Those that say we are entirely responsible and we have to stop everything, are wrong.
Those that say Global Warming is a myth and we need to change nothing, are also wrong.

Whenever there are 2 extreme positions, both are likely wrong, and you need to take a look at the facts.
post #138 of 175
I would like to see the position of every single temperature/sampling point they used including more dominating factors such as our position relative to the sun. We have known for years that the Earth goes throw cycles of hot/cold cycles through its orbit around the sun.

I would also like to see readings of the average solar flux, heat exchange readings, etc.

Also, energy is released into its environment. People who think our contribution does not exert heat into the environment has a very little understanding of the most basic things around them. To state we are the main contributor is a different story.

if they could go back to 1AD they might be able to prove something, but they cant, so the graph proves nothing. its a natural occurrence, and theres nothing man can do to stop it, an Ice age happened before, and man didnt cause that did they?
