News Article: Interesting article on global warming causes and effecte

[Bamaro]

Climate change – due primarly to human-produced greenhouse gases but also because of natural variability – is the cause of most of the temperature increases observed in the USA since 1951, according to a new report released Thursday by the federal U.S. Climate Change Science Program.
The report found that average surface temperatures over the USA have increased about 1.6 degrees since 1951, nearly all in the last 30 years.
One surprising finding from the report was that summertime temperatures across much of the central USA, from the Rockies to the Appalachians, have actually cooled slightly, by about 0.2 degree over the past 50 years.

Seems pretty indisputable to me.

On Causation:

An assessment to identify and attribute the causes of abrupt climate change over North America for the period 1951 to 2006 finds that:
• There are limitations for detecting rapid climate shifts and distinguishing these shifts from quasi-cyclical variations because current reanalysis data only extends back until to the mid-twentieth century. Reanalysis over a longer time period is needed to distinguish between these possibilities with scientific confidence.

So they know that they do not know enough to draw conclusions, but they draw them anyway? :conf2:

An assessment to determine trends and attribute causes for droughts for the period 1951 to 2006 shows that:
• It is unlikely that a systematic change has occurred in either the frequency or area coverage of severe drought over the contiguous United States from the midtwentieth century to the present.
• It is very likely that short-term (monthly to seasonal) severe droughts that have impacted North America during the past half-century are mostly due to atmospheric variability, in some cases amplified by local soil moisture conditions.
• It is likely that sea surface temperature variations have been important in forcing long-term (multi-year) severe droughts that have impacted North America during the past half-century.
• It is likely that anthropogenic warming has increased drought impacts over North America in recent decades through increased water stresses associated with warmer conditions, but the magnitude of the effect is uncertain.

A lot of thoughts come to mind, but this says to me that they think that our use of water is having a greater impact than greenhouse gasses on "drought" conditions in America.

Anyone have any opinions on HAARP and its effect on global warming?

Here is a very interesting speech by Michael Crichton on global warming and science in general. At the very least, it makes you think. Of course, if a person's mind is already made up, nothing can convince them otherwise...

Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

Finally, I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.

The article is relatively long, but I really suggest reading it in its entirety. Like I said, its a good read and makes you think.

Good grief. That was 38 years ago! We have learned a lot since then.

 

[gmart74]

Yes we have actually gotten a lot better- We had crappy computer modeling and we screamed its getting colder!!!! People became hysterical. Then nothing happened so we used crappy computer modeling and screamed it is getting hotter. Nothing really happened so now they are screaming CHANGE!!!! I mean how can we be wrong with CHANGE!!!!!!

Hmmmmm amazingly similar correlation to our political environment as well.........could it be..... noooo I dare not think it..... that just maybe....... Our political system is guiding the science instead of science guiding our political system. Oh well as long as we have CHANGE!! that has to mean we are on the right track.

-14 here monday.. Thats hardly global warming.:eek2:

 

[Bama4Ever831]

Global Warming does not directly mean increased temperatures every day. That is certainly one characteristic. It is much more complicated than simply tropical fever everywhere. Now to be honest it does not matter what I say because as someone as pointed out everyone already has their mind made up so: Roll Tide!

 

[Bama Reb]

Good grief is right. Sure can tell we're getting back into the off-season.
Oh well.

I don't care if I come off as holier than thou, but I went to school and studied this stuff day in and day out with some of the nations top minds, and it doesn't exist. (Yes UNA's Geo department is top notch, always ranked in the top 5 in the nation and run by a former head of National Geographic.) Global Warming is a myth, that's all it's ever been, and anyone who believes otherwise is naive to say the least. (It's a myth in the sense of why, not if.)

It's a lie, just like almost anything else produced by mass media to keep themselves in power and make themselves richer. You can have your own theories as to why it's always mentioned and why mass media likes to push its agenda, but I think it's as simple as what I've stated. It keeps the fat getting fatter.

Is the earth getting warmer? Yes, at least it has been in recent recorded history, but it's not simply for the reasons we are told, and we as humans have an insignifcant impact on climate change.

Just wait, after this winter (it will be one of the coldest in recent memory) all you'll hear from the people in power is that it's getting colder again because there was such an effort to "Go Green" in 2008. Give me a break, we're not as powerful as we like to think we are.

I'm not a lawyer, so I'm not going to tell one how to do his job no matter how many episodes of Law and Order I watch. I'm not a doctor no matter how many episodes of Scrubs I watch, and most of you who believe in Global Warming haven't studied it, so don't act like you know what you're talking about just because Al Gore, ABC News, or CNN told you otherwise.

Funny how you believe what you want to believe. We hate ESPN for "hating Bama," even when they're being fair and relatively unbiased. But when we hear something that plays on our fears (global warming) the media is "our friend" and theres "no way they'd lie to us."

This post could have been much longer, I'm sparing you guys, you can thank me later. . .

I wont be holding my breath.

TUNA, you should know that painting with exclusively broad strokes makes your work look like the product of a kindergarten class.

You haven't begun to see my work, you're the one painting with broad strokes.

 

[CrimsonCT]

Pardon? I haven't even posted in this thread, so you might have a hard time pointing out those broad strokes.

But keep going with the "I'm smarter than everyone who disagrees with me, but I'll spare your feeble minds the burden of citing my vast knowledge" pretension, it comes off well. I argue with people all the time, here especially, but I very rarely just stomp my foot and call them stupid.

You can go through and look at every post of mine from 2005 until now and note that I've rarely if ever come off as pretentious or holier than thou. Like I prefaced my first post in this thread with, this is the one occasion I don't care. The idea of global warming is ridiculous, and the people who believe in it are ridiculous. It's more than opinion on my part, the same can't be said for you.

Like I said, you don't tell a doctor or lawyer how to do his job. And if you happen to, I'm sure they'll have the same response. You can have an opinion, but I can go ahead and tell you it's not the right one. You and I have argued about this same topic before and even when I've brought up facts, you don't seem to care, so it's hardly even worth my time.

So, were the temperature readings inaccurate?

If so, then you can't compare numbers NOW to old, inaccurate numbers...

I honestly think this is a "bandwagon" issue and the tree huggers are promoting every 'scientist' who helps their cause. Many people believe the hype. (I don't.)

 

[NYBamaFan]

Global warming causation being blamed on man, and homosexuality being removed from the list of psychiatric disorders are both the result of politics interfering with science...

This alone dismisses you from the discourse. Good to know.
