Global warming or not?

Nope! Not a theory, only a hypothesis.

theory?
hypothesis?

mmm .... i could never work out which was correct ....

Global Warming is unlikely to be confirmed one way or another until some time in the future.
If it is phoney we may never know it!,
but if it is true then the consequences will be more than we currently observe; although proving man's direct influence may never be certain.

Once Nature loses control of her feedback mechanisms, such as permafrost locking methane in store, then what man in his wisdom has done may be the least of our worries.

Is drinking a gallon of whiskey a day a reasonable thing to do? After all, no doctor can tell you exactly what will go wrong and exactly when.

Watch it! You keep talking like that and the black helicopters will come and take you away.

Actually quite easy.

A hypothesis becomes a theory once it is scientifically verified and replicated.

It's quite mind-boggling to me how virtually any discussion of science topics (e.g. global warming, evolution, stem cell research, flu, etc) these days seems to turn into some kind of attack on science itself by those who really have no clue what science, the scientific method, or the history of science is composed of. It's actually quite scary that the thing that has created civilization as it is is so often under attack.

Using soil or other bore samples has actually shown that there have been extreme temperature movements and cycles.

Nevertheless - back to what I said previously: I won't hurt us to look after the world we live in. It's only on loan to us from future generations.

From: http://www.learnnc.org/lp/pages/1008

"Dendrochronologists have since used Douglass’s technique to make master sequences for several parts of the country. Most reflect regional growth patterns for distinct species. Much of this work focused on regions in the arid Southwest where ancient pinyon pines still live or exist as beams in old houses. In some places there, master sequences extend as far back as 8,700 years."


The seasons and temperatures etc are also mirrored and confirmed in glaciers and ice caps which also deposit in layers that can be matched and tied to tree-ring growth.

For what reason? What would be the purpose?

Do you have a citation to support that?

And what of the confirmation in the ice layers and sediments in the ocean?

As for backing up the facts, why don't you check this week's news. The emails from climate scientist released by either a hacker or possibly a whistle blower are the proof. They show that these scientist have not only worked to keep other scientist who disagreed with them from being published. They also showed that the scientist massaged the data to show what they wanted. This included talking about hiding the decline in temperatures the last couple of years.

I will say again, we know that there has been a very small increase in temperature over the last 159 years. Other than that, we really don't how significant this will turn out to be. Nor do we know how much man has contributed to this. We do know that not all the answers are in due to the fact that the climate models do not work properly. Since they don't, we know that we are making errors in the theories being used.

Please provide links to legitimate scientific support and confirmation of your speculation otherwise that is all it is, speculation.

As far as 159 years. What you are saying may or may not be scientifically confirmed but it must be taken in the entire context of climate history.

Jeeze Icarusbop, see what you started now.

Current poll results show 46% saying it's happening and it's our fault
another 20% say it's happening (but not our fault)

So with 66% in agreement that global warming is happening, shouldn't we be trying to do something about it?

Who's wit me for nuclear winter?


Seriously though if 2/3's agree it is happening, shouldn't we be doing everything we can to stop or slow it down?

Oh my, this is pretty funny:

Okay I can live with that wording.

This reminds me of what's going on in this tread; lots of yelling and very little listening!

Anyone can become a Dr.PhD.Soph.Phil.Gov.Univ.Doz. just by using google!



I'm not sure if global warming is THE thing that will break our backs some time in the near future, but our polluting and raping of our planet surely will cause severe problems down the road. And if global warming is fake but trying to fix this fake problem will result in an overall improvement of the planet's condition, then I'm all for it.

I think people should all do their part. It doesn't take much - just shop sensibly, and you'll help.

Pfft, I don't have any kids; so I think I should be cut a little slack.
After all, when I've popped my clogs I'll have done all the damage I'll do - there'll be no progeny to carry on doing it for generations to come.
