The remaining (well-funded) skeptics are trying to cast doubt on whether or not the change is human-caused, so perhaps this would be a better area for discussion? Thankfully no one is doubting the credibility of thermometers anymore...
And I can't help but point out the fact that the administrator asked such a question. Shows what kind of site this is: typical cooperate greenwashing.

Welcome dawei. I agree with your main point concerning whether climate change is really happening. Despite the best efforts of McIntyre and others it is clear that our world is warming. The skeptics arguments have generally changed to whether the warming is anthropogenic or not and if so we have the moral and financial abilities to do something about it. In general their arguments are as weak as they have previously been when they were claiming that the world was not warming.
As for the politics of this site…
GETENERGYACTIVE.org is obviously run by Edison Electric. I suspect that it is a PR move by them. Because of California’s semi-regulated energy market and the fact that Ca. actively encourages its power companies to encourage conservation. Edison obviously gains something from it no matter what the opinions posted here are pro or con its ability to sell more energy.
I have sympathy for the administrators of this site as it is hard to grow a new forum (although this forum seems to have an exceptionally high advertising budget). Posting controversial topics such as “Is it happening?” are a way to draw in new posters.
In their defense; they have never altered or deleted a post of mine and my posts generally do not encourage energy consumption. I am not in any way affiliated with them and I think that anthropogenic warming should be considered to be a big problem for anyone concerned for the welfare of subsequent generations.
It would have been easy enough for the administrator to use a pseudonym to avoid being identified as the administrator. At least (s)he seems relatively honest, even if the topic presented seems somewhat biased.
I hope you stick around dawei because you seem to be of kind, and at least thus far this forum has allowed freedom of expression.
PS. I was just “timed out” for the first time here. I doubt this had to do with my politics, but simply the traffic. Overload is the bane of all internet forums. I am surprised that it happened with so little traffic...

"(well-funded) skeptics?" With electric utilities and especially General Electric poised to reap historic profits from the dismantling and (presumably) restructuring of the US economy, they are putting some pretty significant dollars BEHIND AGW.
Do you really believe the AGW "scientists" are forecasting the planet's doom out of personal concern? If/When their position wins out, they will be in line for $billions in consultation fees and book deals. Ironically, Al Gore -- one of America's most prolific wasters of energy -- is already cashing in. (even more ironically, George Bush's Crawford, TX, ranch uses almost no commercially-generated power)
I hate to punch a hole in your mental universe, but there is always a money trail; if you follow it, you can find out what's REALLY going on.
As to whether the earth is warming, the evidence indicates that it is, but not why it is. Meteorological prediction is not a hard science. Meteorologists can't tell with any certainty what the weather will do the day after tomorrow, yet we are supposed to lose sleepover their 100 year predictions?
Computer models are built using assumptions; they cannot create knowledge. Somewhere, the AGW models included the assumption that human progress was responsible for climate change. AGW theory is a self-fulfilling prophesy.
By the way, I am not on anybody's payroll.

Show me this evidence already; you claim GE is putting all of this money into spreading the AGW hoax, let's see some support.

The scientists on the IPCC make virtually nothing and spend long hours doing it. No scientist on this earth became a scientist for the money. Show me some kind of evidence, even a shred, that this is all an elaborate hoax to make money for a few people. It's just ridiculous.
Also, all of Gore's revenues from Inconvenient Truth were all donated to charity. The man was rich long before he knew what AGW was. The argument that he uses a lot of energy is one of the oldest and weakest out there for saying we should not take action. For one thing, the Gores pay extra to have their electricity come from renewable sources. Another thing, this is none of your business. Here is a man volunteering his time and dedicating his entire life to an issue, and you criticize him for not being perfect. Everyone who makes that argument reminds me of a spoiled little brat, whining because the other kid won't share. You feel defensive because he is saying what you are doing is wrong, and instead of maybe listening you have a mental block right from the start. Well, even if you can't listen to him, he did not invent AGW and there are plenty of other voices to listen to. Don't associate a global issue with a single man, try to be a little more unbiased.

Another common argument, courtesy of Crichton I believe. Fine, we don't know for certain if it will rain next week. Actually, no one has any idea. But I'd bet a hundred dollars it will be warmer in the northern hemisphere in 6 months than it is right now. Related to that, I bet you it was colder in general during the last ice age than it is now, don't you agree? Simple predictions of relative warmth and coolness have nothing to do with complicated weather patterns, and can be easily predicted. You even admitted yourself the earth is warming. In State of Fear Crichton was arguing that the world is NOT in fact warming. We are past this now, and even he has moved on.

 I'm really confused now! Since the mid 70s I've been concerned that this planet will be too cold for human habitation as scientists were then warning us. Then in the 90s the same scientists told us, no -the earth is heating up. But this past winter has been the coldest on record in various parts of the world, especially China and the Southern US, and the snowfall in Syracuse NY broke all historic records there. Now I read in some scientific journals that the ice caps are "coming back with a vengence" and various scientists around the world (no connection to the bad guys, American business) that the global temperature will actually cool over the next few years. So I guess I'll stick with first uneducated estimate: global warming and cooling are simply natural phenonenoms of nature. To believe otherwise one would have to think that the world would either; A: still be covered with ice as in the ice age, or; B: we'd still be experiencing the terrific temperatures it must have taken to melt all that ice

Global warming has stopped!
Recent scientific studies may make 2007 go down in history as the "tipping point" of man-made global warming fears. A progression of peer-reviewed studies have been published which serve to debunk the United Nations on climate change.
Paleoclimate scientist Bob Carter, who has testified before the U.S. Senate Committee on Environment & Public Works (LINK), noted in a June 18, 2007 essay that global warming has stopped.
"The accepted global average temperature statistics used by the Intergovernmental Panel on Climate Change show that no ground-based warming has occurred since 1998. Oddly, this eight-year-long temperature stasis has occurred despite an increase over the same period of 15 parts per million (or 4 per cent) in atmospheric CO2. Second, lower atmosphere satellite-based temperature measurements, if corrected for non-greenhouse influences such as El Nino events and large volcanic eruptions, show little if any global warming since 1979, a period over which atmospheric CO2 has increased by 55 ppm (17 %)," (LINK)
In August 2007, the UK Met Office was finally forced to concede the obvious: global warming has stopped. (LINK) The UK Met Office acknowledged the flat lining of global temperatures, but in an apparent attempt to keep stoking man-made climate alarm, the Met Office is now promoting more unproven dire computer model projections of the future. They now claim climate computer models predict "global warming will begin in earnest in 2009" because greenhouse emissions will then overtake natural climate variability.
Southern Hemisphere is COOLING
UN scientist Dr. Madhav L. Khandekar, a retired Environment Canada scientist and an expert IPCC reviewer in 2007, explained on August 6, 2007 that the Southern Hemisphere is cooling. "In the Southern Hemisphere, the land-area mean temperature has slowly but surely declined in the last few years. The city of Buenos Aires in Argentina received several centimeters of snowfall in early July, and the last time it snowed in Buenos Aires was in 1918! Most of Australia experienced one of its coldest months of June this year. Several other locations in the Southern Hemisphere have experienced lower temperatures in the last few years. Further, the sea surface temperatures over world oceans are slowly declining since mid-1998, according to a recent world-wide analysis of ocean surface temperatures," Dr. Khandekar explained. (LINK)
Meteorologist Joseph Conklin, who launched the skeptical website www.ClimatePolice.com in 2007, recently declared the "global warming movement [is] falling apart."
"A few months ago, a study came out that demonstrated global temperatures have leveled off. But instead of possibly admitting that this whole global warming thing is a farce, a group of British scientists concluded that the real global warming won't start until 2009," Conklin wrote in an August 10, 2007 blog post on his website. (LINK)
Climate models made by unlicensed 'software engineers'
But the credibility of these computer model predictions took a significant hit in June 2007 when Dr. Jim Renwick, a top UN IPCC scientist, admitted that climate models do not account for half the variability in nature and thus are not reliable. "Half of the variability in the climate system is not predictable, so we don't expect to do terrifically well," Renwick conceded. (LINK)
Another high-profile UN IPCC lead author, Dr. Kevin Trenberth, recently echoed Renwick's sentiments about climate models by referring to them as "story lines."
"In fact there are no predictions by IPCC at all. And there never have been. The IPCC instead proffers 'what if' projections of future climate that correspond to certain emissions scenarios," Trenberth wrote in journal Nature's blog on June 4, 2007. He also admitted that the climate models have major shortcomings because "they do not consider many things like the recovery of the ozone layer, for instance, or observed trends in forcing agents. There is no estimate, even probabilistically, as to the likelihood of any emissions scenario and no best guess." (LINK)
IPCC reviewer and climate researcher Dr Vincent Gray, of New Zealand, an expert reviewer on every single draft of the IPCC reports going back to 1990 and author of The Greenhouse Delusion: A Critique of "Climate Change 2001," declared "The claims of the IPCC are dangerous unscientific nonsense" in an April 10, 2007 article. (LINK)
"All [UN IPCC does] is make 'projections' and 'estimates'. No climate model has ever been properly tested, which is what 'validation' means, and their 'projections' are nothing more than the opinions of 'experts' with a conflict of interest, because they are paid to produce the models. There is no actual scientific evidence for all these 'projections' and 'estimates,'" Gray noted.
In addtion, meteorologist Dr. Hendrik Tennekes, a scientific pioneer in the development of numerical weather prediction and former director of research at The Netherlands' Royal National Meteorological Institute, recently compared scientists who promote computer models predicting future climate doom to unlicensed "software engineers."
"I am of the opinion that most scientists engaged in the design, development, and tuning of climate models are in fact software engineers. They are unlicensed, hence unqualified to sell their products to society," Tennekes wrote on February 28, 2007. (LINK)
Should we spend a trillion dollars on "Global warming" when, in fact, the earth is cooling

Dawei,
Please read my posting.
I am not going to flame you for regurgitating the liberal leftist lies promoted by those who crave control of the masses through additional impositions of laws, rules, regulation as means to divide the finite resources of this planet according to their needs. Al Gore is wealthy becaue of his Nickel processing plant given to his father by Armand Hammer. Gore is one of the worst polluters in Tennesse history. He is a politician without scientifice credentials and without a soul, a moral compass, or an ounce of compassion. If you believe what they sell I have a bridge in Florida I would like to offer to you. Study to show yourself the facts and quit relying on the mass hysteria created by those who wish you no good.
Live long and prosper.

If you want to throw stereotypes, fine. I can flame the right-wing, war loving, selfish, bible-obsessed rednecks too. The people who think there is nothing wrong with the idea of six people having the entire world's wealth, as long as they fought hard to get it. In the wild there is no such thing as compassion, and we are all just animals anyway right? Wait, no, that conflicts with the bible...how do you guys work again?
Seriously, both the liberal and conservative stereotypes are ridiculous. Not a single person is like either of them, so let's not throw them out there please. And actually, I am not a liberal anyway, not even a democrat. Being concerned about global warming is my scientific belief, not social. I don't know when exactly people who have a concern for the environment got tied up with hippies, homosexuals and pro-choicers, but until you can give me a good reason why they should be, let's leave the 'liberal' card out.

You can think what you want about him, I really don't care. Don't think that just because I am concerned about global warming I regard him as a saint; I have not even seen his movie. There is a plethora of other evidence out there, and I know that everything he says is just copied from other people.
I think he did well to bring global warming to many in America who had not yet heard of it however, but he did not "invent" it like your t-shirt probably says. I really believe most people hate Gore for a good reason though, and that's because he went about it completely in the wrong way. He tried to make people feel guilty, and the natural response to that for people on this side of immaturity is to react with hostility.
The conspiracy theorists like yourself think they are being more open minded, but what they are really doing is reverting to a childlike state of a desire to feel superior by knowing something others don't. You are the stubborn ones; as for me, I welcome your laughter if this turns out to be just a big scare, because honestly it will be such a great sigh of relief that I really won't care. But I hope that if this does play out to the worst of our expectations, you will be able to swallow that little pain in your chest, show a little selflessness and lend a hand; it is mostly our mess, after all.

Watch the web for climate change truths
By Christopher Booker
Last Updated: 12:01am BST 04/05/2008
Have your say Read comments
A notable story of recent months should have been the evidence pouring in from all sides to cast doubts on the idea that the world is inexorably heating up. The proponents of man-made global warming have become so rattled by how the forecasts of their computer models are being contradicted by the data that some are rushing to modify the thesis.
• Read more from Christopher Booker
So a German study, published by Nature last week, claimed that, while the world is definitely warming, it may cool down until 2015 "while natural variations in climate cancel out the increases caused by man-made greenhouse gas emissions".
A little vignette of the media's one-sided view was given by recent events on Snowdon, the highest mountain in southern Britain. Each year between 2003 and 2007, the retreat of its winter snow cover inspired reports citing this as evidence of global warming.
In 2004 scientists from the University of Bangor made headlines with the prediction that Snowdon might lose its snowcap altogether by 2020. In 2007 a Welsh MP, Lembit Opik, was saying "it is shocking to think that in just 14 years snow on this mountain could be nothing but a distant memory".
Last November, viewing photographs of a snowless Snowdon at an exhibition in Cardiff, the Welsh environment minister, Jane Davidson, said "we must act now to reduce the greenhouse gases that cause climate change".
advertisement
Yet virtually no coverage has been given to the abnormally deep spring snow which prevented the completion of a new building on Snowdon's summit for more than a month, and nearly made it miss the deadline for £4.2 million of EU funding. (Brussels eventually extended the deadline to next autumn.)
Two weeks ago, as North America emerged from its coldest and snowiest winter for decades, the US National Climate Data Center, run by the National Oceanic and Atmospheric Administration (NOAA) issued a statement that snow cover in January on the Eurasian land mass had been the most extensive ever recorded, and that in the US March had been only the 63rd warmest since records began in 1895.
While global warming enthusiasts might take cheer from the NOAA's claim that "average global land temperature" in March was "the warmest on record", this was in striking contrast to a graph published last week on the Climate Audit website by Steve McIntyre.
Tracking satellite data for the tropical troposphere, it showed March temperatures plunging to one of their lowest points in 30 years.
Mr McIntyre is the computer expert who exposed the infamous "hockey stick" graph - that icon of warmist orthodoxy which showed global temperatures soaring recently to their highest level for 1,000 years. He showed that the computer model that produced this graph had been so designed that it would have conjured even random numbers from a telephone directory into the shape of a hockey stick).
On April 24 the World Wildife Fund (WWF), another body keen to keep the warmist flag flying, published a study warning that Arctic sea ice was melting so fast that it may soon reach a "tipping point" where "irreversible change" takes place. This was based on last September's data, showing ice cover having shrunk over six months from 13 million square kilometres to just 3 million.
What the WWF omitted to mention was that by March the ice had recovered to 14 million sq km (see the website Cryosphere Today), and that ice-cover around the Bering Strait and Alaska that month was at its highest level ever recorded. (At the same time Antarctic sea ice-cover was also at its highest-ever level, 30 per cent above normal).
The most dramatic evidence, however, emerged last week with an announcement by Nasa's Jet Propulsion Laboratory that an immense slow-cycling movement of water in the Pacific, known as the Pacific Decadal Oscillation (PDO), had unexpectedly shifted into its cool phase, something which only happens every 30 years or so, ultimately affecting climate all over the globe.
Discussion of this on the invaluable Watts Up With That website, run by the US meteorologist Anthony Watts, shows how the alternations of the PDO between warm and cool coincided with each of the major temperature shifts of the 20th century - warming after 1905, cooling after 1946, warming again after 1977 - and how the new shift to a cool phase could have repercussions for decades to come.
It is notable that the German computer predictions published last week by Nature forecast a decade of cooling due to deep-ocean movements in the Atlantic, without taking account of how this may now be reinforced by a similar, even greater movement in the Pacific.
Mr Watts points out that the West coast of the USA might already be experiencing these effects in the recent freezing temperatures that have devastated orchards and vineyards in California, prompting an appeal for disaster relief for growers who fear they may have lost this year's crops.
Mr Watts's readers are amused by the explanation from one warmist apologist that "these natural climate phenomena can sometimes hide global warming caused by human activities - or they can have the opposite effect of accentuating it".
It is striking, in view of the colossal implications of the current response to "the greatest challenge confronting mankind" - as our politicians love to call it - how this hugely important debate is almost entirely overlooked by the media, and is instead conducted largely on the internet, through expert websites such as those run by Mr McIntyre and Mr Watts.
On one hand our politicians are committing us to spending unimaginable sums on wind farms, emissions trading schemes, absurdly ambitious biofuel targets, and every kind of tax and regulation designed to reduce our "carbon footprint" - all based on blindly accepting the predictions of computer models that the planet is overheating due to our output of greenhouse gases.
On the other hand, a growing number of scientists are producing ever more evidence to show how those computer models are based on wholly inadequate data and assumptions - as is being confirmed by the behaviour of nature itself (not least the continuing non-arrival of sunspot cycle 24).
The fact is that what has been happening to the world's climate in recent years, since global temperatures ceased to rise after 1998, was not predicted by any of those officially-sponsored models. The discrepancy between their predictions and observable data becomes more glaring with every month that passes.
It won't do for believers in warmist orthodoxy to claim that, although temperatures may be falling, this is only because they are "masking an underlying warming trend that is still continuing" - nor to fob us off with assurances that the "German model shows that higher temperatures than 1998, the warmest year on record, are likely to return after 2015".
In view of what is now at stake, such quasi-religious incantations masquerading as science are something we can no longer afford. We should get back to proper science before it is too late.

I sold a small chain of gyms i ownd 2 yrs ago after a trip to a research station in northern canada smacked me out of my cozy little worlds . The sight of the polar ice cap missing 400 thousand sq miles of ice was enough to total re-evaluate my life and the future of this planet! I have since traveled ti every corner of this planet to get the real(not what is being told or made to believe) picture. Well that picture isn't pretty! Ck out my blog for all the gory details and much more...http://illuminationjoram.blogstream.com there are three sections cosmic painter is primarily enviornmental issues. let me know what your opinions and thoughts are.

Greenhouse effect cure (there are no real cures but this may help till we can find one).
First I want to point out that there are no real, viable short term, or easy methods of curing our Global warming woes. The damage to the environment has already been done and is, for all intent and purposes, basically irreversible.
It is likely, however, that any type of plan to get rid of Global warming, will require some type of dramatic ecological compromises.
Some will say that all we need to do is give up industry on the planet and the world will eventually go back to the way it was. I say it is too late for that solution (as a short term solution anyway). The damage done by increased greenhouse emissions has already taken its toll. This is evident by the melting of polar ice and glaciers across the globe.
We cannot get the world back the way it was, even as of fifty years ago, much less stop the damage that will still occur in the future. Sure we could try to stop all industry that will cause pollution, but at what cost. Without industry we could not sustain the present world population. Giving up industry and sacrificing billions of people on this planet in the process, is not a viable solution (even trying to merely lower greenhouse emissions is at best a temporary solution).
My plan, however, will require the use of old tires and recycled plastics. Of course it will require some engineering feats also, and a few ecological compromises. The benefits of using these wasted products will far outweigh the compromises required.
My idea is to build large floating islands (white on top, to reflect sunlight back out of our planet) made from used tires (filled with co2) and recycled plastics. Yes there are engineering and ecological problems, but everyone has to admit there are worse problems in our current situation.
The biggest problem we have now is not just the fact that we have more greenhouse gasses trapping heat in, but we are getting less and less sunlight being reflected out from the planet. As the snow cover melts from more and more of the planets surface, the sunlight heats up more parts of the earth that once reflected light back out. It is like a dog chasing its tail (until it gets dizzy and falls from exhaustion). As global warming just keeps building on itself till the ecological balance fails, and this planet will no longer sustain the teeming human populations.
So the only feasible solution is to build a bunch of artificial reflection “islands” across the planet.
There will be other benefits realized, once we build enough of these islands. One of the problems associated with the increased temperatures we are experiencing is the possibility of increased hurricane intensity and frequency. Having enough of these floating islands in strategic points in the oceans will help to alleviate this problem also.
It is a well known fact that hurricanes form in areas of the ocean where the temperature rises above approximately 80 degrees Fahrenheit. If we can keep those areas below that temperature (by reflecting sunlight away), we can prevent the formation of hurricanes. Without these floating islands, hurricanes will probably continue to increase in intensity and frequency…
We need a solution to deal with our Global warming woes, and we need it now. Even if this is a difficult path to follow, it will pay off in the future.
The overall problems I see for Greenhouse effect is that we can go green all we want, but Global warming and our constant desire to be comfortable, will eventually undermine any efforts we may do. Unless we can get rid of some of the excess heat in this world, we will always be under the eventual threat of a thermal overheating demise.

I'm wondering about the scientific challenges of defining the variables associated with global climate change and then analyzing them with multivariate statistics, etc.
However, my research training is in the social sciences, so I've limited my research to the perceptions and attitudes associated with climate change.
I have an interesting survey about such beliefs in which some of you may be interested.

Climate change is, of course, real. I think no one really doubts that -- the debate tends to center on the cause, natural, human-induced, a combination? And most scientists now do not ask is it real, but "how much?"
That said, I think if we focus on the health harm that polluting at such a prodigious rate is causing, we may make more progress. Rather than getting bogged down on "well, why should I do anything if it might not be real" -- we could point to the health concerns. CA has has over 22000 deaths attributed to air pollution. That is primarily human-caused death. Murder? Suicide? Some macabre combination of the two? ;-)
But seriously, if we had a serial killer who had killed 22 people -- a factor of 1000 times less -- people would be afraid to leave the house, would be in an uproar. Why are they not in an uproar over this? My guess is a couple of things. First -- it is slow death. Death, but slower, not like a bullet or knife or such. Second, it is likely affecting certain populations (the infirm, those with respiratory problems or chemical sensitivities) more than others, so it is easier to stick one's head in the sand and say, "Well, it won't hurt me." A callous attitude, but human enough. And third -- to prevent these deaths would take a radical change in our lives. Either going without our cars (and in America, we just don't view that as an option -- especially as most of us have lousy mass transit at best) or having some radically different technology, which would take both time and money. (Replacing a car is costly, no matter the long-term benefits.)
And for those who commented on the cold winter -- according to global warming models, it is expected that certain regions will have colder than (previous) average winters, other areas warmer than (previous) average winters. But the overall net effect is warming. And that is undeniable. The arctic ice sheet is literally melting away.
And, for those living in coastal regions, to quote Bill Cosby (from the Noah skit) "How long can you tread water? Ha, ha, ha..."
