To say 'well I am not sure I drank enough to be legally drunk and therefore a danger on the road I will just go ahead and drive home' is no excuse for killing someone while under the influence.
Just because we can't be 100% sure does not mean we should not modify our behaviors that are causing potential impacts on the planet.
Your first link to your thread "Catastrophic 'Global Warming' "Consensus" & "Causes"!" has nothing to back it up other than a link to wiki. and is FAR from solid evidence.
This includes ANY type of science degree, you know things like veterinary science, computer science, etc...
Only 9100 have PhDs and it does not even bother to say how many research climate or even work in the profession. Thus it is another weak, if not worthless, argument.

"Peer" is the right word. The same people writing the papers are the same ones reviewing them while turning down those to the contrary. This very 'conspiracy' has been disclosed in the email controversy:
link
Peer review (also known as refereeing) is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field. Peer review requires a community of experts in a given (and often narrowly defined) field, who are qualified and able to perform impartial review. Impartial review, especially of work in less narrowly defined or inter-disciplinary fields, may be difficult to accomplish; and the significance (good or bad) of an idea may never be widely appreciated among its contemporaries. Although generally considered essential to academic quality, peer review has been criticized as ineffective, slow, and misunderstood (see anonymous peer review and open peer review).
Pragmatically, peer review refers to the work done during the screening of submitted manuscripts and funding applications. This process encourages authors to meet the accepted standards of their discipline and prevents the dissemination of irrelevant findings, unwarranted claims, unacceptable interpretations, and personal views. Publications that have not undergone peer review are likely to be regarded with suspicion by scholars and professionals.
"Consensus" is ]EXACTLY opinion. I cannot stress EXACTLY enough. It is the opinion of a group of people. Consensus OPINION, not SCIENCE. Catastrophic global warming is a THEORY, more like a HYPOTHESIS, ABSOLUTELY NOT "LAW". "Law" is true, proven undisputable science. While things may be in the realm of 'science', that alone doesnt make them 'lawful' science in any of the context in this sort of discussion. PERIOD.
Scientific consensus is the collective judgement, position, and opinion of the community of scientists in a particular field of study. Consensus implies general agreement, though not necessarily unanimity. Scientific consensus is not by itself a scientific argument, and it is not part of the scientific method. Nevertheless, consensus may be based on both scientific arguments and the scientific method. [1]
Consensus is normally achieved through communication at conferences, the process of publication, replication (reproducible results by others) and peer review. These lead to a situation where those within the discipline can often recognize such a consensus where it exists, but communicating that to outsiders can be difficult. On occasion, scientific institutes issue position statements intended to communicate a summary of the science from the "inside" to the "outside". In cases where there is little controversy regarding the subject under study, establishing what the consensus is can be quite straightforward. Scientific consensus may be invoked in popular or political debate on subjects that are controversial within the public sphere but which may not be controversial within the scientific community, such as evolution.[2][3]
I agree we can not be 100% certain,
Thank you, because if we could be certain, then that would be science.
There wouldnt be ANY debate to be had. But the fact is there is SERIOUS debate, both sides having great points that counter certain parts of other points.
Clear signs of 'lawlessness'.
By and large, or at least in my case, we 'deniers' argue 'we dont know absolutely', the science in inconclusive. The Alarmists are the ones SCREAMING they're absolutely right and there is nothing to duscuss other than how much to tax everybody, overall.
This includes the alarmist 'scientists'. If they had their way, as proven by the emails, their opponents would be silenced, there would be no discussion. It would end on their arguments alone. THAT IS NOT SCIENTIFIC. How can you follow these people, and take part in it yourself??
but we can make decision based on our best analysis of the situation.
Then follow my link to my old 'consensus' thread and comment on the 'Consensus of Economists" subsection I wrote. 'Put your money where your mouth is.' lol
Just because we can't be 100% sure does not mean we should not modify our behaviors that are causing potential impacts on the planet.
I'm waiting for the Alarmist messiah, Al Gore, to modify his behavior. Honestly, I long ago have. I'd bet I'm greener than most of the alarmists out there, but I do it for personal reliance, financial sustainabilty, freedom, survivalism and hobby. NOT to repent my guilty sins based on flawed 'science'.
Your first link to your thread "Catastrophic 'Global Warming' "Consensus" & "Causes"!" has nothing to back it up other than a link to wiki. and is FAR from solid evidence.
Wiki-copout, how weak.
This article documents current scientific opinion on climate change as given by synthesis reports, scientific bodies of national or international standing, and surveys of opinion among climate scientists. It does not document the views of individual scientists, individual universities, or laboratories, nor self-selected lists of individuals such as petitions.
National and international science academies and scientific societies have assessed the current scientific opinion, in particular on recent global warming. These assessments have largely followed or endorsed the Intergovernmental Panel on Climate Change (IPCC) position of January 2001 that states:
An increasing body of observations gives a collective picture of a warming world and other changes in the climate system... There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.[1]
Since 2007, no scientific body of national or international standing has maintained a dissenting opinion. A few organisations hold non-committal positions.
This includes ANY type of science degree, you know things like veterinary science, computer science, etc...
Only 9100 have PhDs and it does not even bother to say how many research climate or even work in the profession. Thus it is another weak, if not worthless, argument.
"Only" 9100 Phd's? Have you ever tried to count all the way to 9100? And computer scientists who write flawed computer models are surely in the IPCC group.

Policy-makers and the media, particularly in the United States, frequently assert that climate science is highly uncertain. Some have used this as an argument against adopting strong measures to reduce greenhouse gas emissions. For example, while discussing a major U.S. Environmental Protection Agency report on the risks of climate change, then-EPA administrator Christine Whitman argued, "As [the report] went through review, there was less consensus on the science and conclusions on climate change" (1). Some corporations whose revenues might be adversely affected by controls on carbon dioxide emissions have also alleged major uncertainties in the science (2). Such statements suggest that there might be substantive disagreement in the scientific community about the reality of anthropogenic climate change. This is not the case
link
Peer review...
Trying to dismiss the Science Article I posted by saying 'it is hooey because it is peer reviewed' is incredibly weak.
Sorry I did not watch the video but arguing that peer-reviewed scientific literature is a joke mate.
First you decry AGW science as phony science then you bash the peer-review process.
It seems to me you use any angle to argue your point with no regard for consistency.
Scientific consensus is the collective judgement, position, and opinion of the community of scientists in a particular field of study.
Science does not equal 100% certainty. Show me any proof of such a statement?
Science is the continual advancement of UNDERSTANDING. Not the end of discussion or exploration.
Clear signs of 'lawlessness'.
#1 there is no absolute proof but there is EVIDENCE. How arrogant to assume we dont need to change behavior because we dont know 100% that our actions are endangering the planet.
#I do believe that there is enough evidence to make the decision to act to prevent the POSSIBILITY that we are on a dangerous course.
Just because we can't be 100% sure does not mean we should not modify our behaviors that are causing potential impacts on the planet.
It also avoids the REAL issue i raise in my above quote. We have evidence that we are endangering the PLANET shouldn't we act regardless of not having 100% positive knowledge on the issue.
What is weak is your thread, not the article.

In case youre unaware, the 'consensus' study is deeply flawed, but even at face value her updated report only shows 20% claiming the human element. 55% merely talk about cliamte change in general, NOT saying that humans are causing it. So your consensus arguement is ridiculous on that front.
Consensus of opinions IS NOT SCIENCE.
Scientific consensus is the collective judgement, position, and opinion of the community of scientists in a particular field of study. Consensus implies general agreement, though not necessarily unanimity. Scientific consensus is not by itself a scientific argument, and it is not part of the scientific method. Nevertheless, consensus may be based on both scientific arguments and the scientific method.
I've already explained this. I thought I had in laymans terms. Let me try again. There are fields of science, and then there is settled science. Settled science is law. It is settled that the climate is a field of science, but say being able to predict is unsettled. If it were scientific law, as Al Gore claims, then there would be very little debate. We wouldnt be having this discussion. There'd be nothing to talk about.
As such, a law is limited in applicability to circumstances resembling those already observed, and is often found to be false when extrapolated. Ohm's law only applies to constant currents, Newton's law of universal gravitation only applies in weak gravitational fields, the early laws of aerodynamics such as Bernoulli's principle do not apply in case of compressible flow such as occurs in transonic and supersonic flight, Hooke's law only applies to strain below the elastic limit, etc.
Then why do the alarmist scientists and proponents work in tandem to stomp out debate and discussion? i.e. holocaust deniers.
What do you suggest we do, that wont harm more lives in the process? er wait, you dont know because you obviously havent listened to the actual economists and dont intend to. Scientists arent the ones who should write policy. Scientists give their take and then economists tell the people and the politicians the cost/risk analysis. SOmehow we rarely hear from economists, only the scientits and politicians.

Multicentury glacier fluctuations in the Swiss Alps during the Holocene

Subfossil remains of wood and peat from six Swiss glaciers found in proglacial fluvial sediments indicate that glaciers were smaller than the 1985 reference level and climatic conditions allowed vegetation growth in now glaciated basins. An extended data set of Swiss glacier recessions consisting of 143 radiocarbon dates is presented to improve the chronology of glacier fluctuations. A comparison with other archives and dated glacier advances suggests 12 major recession periods occurring at 9850- 9600, 9300-8650, 8550-8050, 7700-7550, 7450-6550, 6150-5950, 5700-5500, 5200-4400, 4300-3400, 2800-2700, 2150-1850, 1400-1200 cal. yr BP. It is proposed that major glacier fluctuations occurred on a multicentennial scale with a changing pattern during the course of the Holocene. After the Younger Dryas, glaciers receded to a smaller extent and prolonged recessions occurred repeatedly, culminating around 7 cal. kyr BP. After a transition around 6 cal. kyr BP weak fluctuations around the present level dominated. After 3.6 cal. kyr BP less frequent recessions interrupted the trend to advanced glaciers peaking with the prominent ‘Little Ice Age’. This trend is in line with a continuous decrease of summer insolation during the Holocene.

Abstract
A ca. 1400-yr record from a raised bog in Isla Grande, Tierra del Fuego, Argentina, registers climate fluctuations, including a Medieval Warm Period, although evidence for the ‘Little Ice Age’ is less clear. Changes in temperature and/or precipitation were inferred from plant macrofossils, pollen, fungal spores, testate amebae, and peat humification. The chronology was established using a 14C wiggle-matching technique that provides improved age control for at least part of the record compared to other sites. These new data are presented and compared with other lines of evidence from the Southern and Northern Hemispheres. A period of low local water tables occurred in the bog between A.D. 960–1020, which may correspond to the Medieval Warm Period date range of A.D. 950–1045 generated from Northern Hemisphere tree-ring data. A period of cooler and/or wetter conditions was detected between ca. A.D. 1030 and 1100 and a later period of cooler/wetter conditions estimated at ca. cal A.D. 1800–1930, which may correspond to a cooling episode inferred from Law Dome, Antarctica.
Late Holocene, high-resolution glacial chronologies and climate, Kenai Mountains, Alaska

Recent retreat of outlet glaciers from the Harding and Grewingk-Yalik Icefields has revealed a vast array of deposits on the eastern and western flanks of the Kenai Mountains that records multiple glacier advances into coastal forests during late Holocene time. Treering dating, together with radiocarbon and lichenometric analyses, allows for the reconstruction of these glacial fluctuations to decadal precision over the past two thousand years.
The records of fluctuations are derived from 16 land-terminating and seven tidewater glaciers in three fjord systems, as well as two cirque glaciers. Three major intervals of Holocene glacier expansions are evident; they occurred about 3600 yr B.P., 600 A.D., and during the Little Ice Age, from 1300 to 1850 A.D. The earliest expansion beyond present ice margins is known only from the McCarty tidewater glacier. The 600 A.D. event involved the simultaneous advance of land-terminating and tidewater glaciers. During the Little Ice Age, however, tidewater glaciers were advancing several centuries prior to their land-terminating neighbors. Those land-terminating glaciers on the western mountain flank retreated from their Little Ice Age maxima as much as two centuries before those on the eastern mountain flank.
Land-terminating tongues on the eastern, more maritime, mountain flank have shown more sensitivity to variations in winter precipitation during the Little Ice Age and within recent decades than the more continental glaciers on the western flank that are affected more by summer temperatures. The glacial and climatic records suggest that advances of the ice tongues from about 1420 to 1460 A.D., between 1640 and 1670 A.D., at about 1750 A.D., and from 1880 to 1910 A.D. reflected times of increased winter precipitation. Advances between 1440 to 1460 A.D., from 1650 to 1710 A.D., and from 1830 to 1860 A.D. followed intervals of lower summer temperatures.

Title: Torneträsk tree-ring width and density ad 500–2004: a test of climatic sensitivity and a new 1500-year reconstruction of north Fennoscandian summers

Abstract: This paper presents updated tree-ring width (TRW) and maximum density (MXD) from Torneträsk in northern Sweden, now covering the period ad 500–2004. By including data from relatively young trees for the most recent period, a previously noted decline in recent MXD is eliminated. Non-climatological growth trends in the data are removed using Regional Curve Standardization (RCS), thus producing TRW and MXD chronologies with preserved low-frequency variability. The chronologies are calibrated using local and regional instrumental climate records. A bootstrapped response function analysis using regional climate data shows that tree growth is forced by April–August temperatures and that the regression weights for MXD are much stronger than for TRW. The robustness of the reconstruction equation is verified by independent temperature data and shows that 63–64% of the instrumental inter-annual variation is captured by the tree-ring data. This is a significant improvement compared to previously published reconstructions based on tree-ring data from Torneträsk. A divergence phenomenon around ad 1800, expressed as an increase in TRW that is not paralleled by temperature and MXD, is most likely an effect of major changes in the density of the pine population at this northern tree-line site. The bias introduced by this TRW phenomenon is assessed by producing a summer temperature reconstruction based on MXD exclusively. The new data show generally higher temperature estimates than previous reconstructions based on Torneträsk tree-ring data. The late-twentieth century, however, is not exceptionally warm in the new record: On decadal-to-centennial timescales, periods around ad 750, 1000, 1400, and 1750 were equally warm, or warmer. The 200-year long warm period centered on ad 1000 was significantly warmer than the late-twentieth century (p < 0.05) and is supported by other local and regional paleoclimate data. The new tree-ring evidence from Torneträsk suggests that this “Medieval Warm Period” in northern Fennoscandia was much warmer than previously recognized.

Total Solar Irradiance Trend During Solar Cycles 21 and 22
Richard C. Willson
Results from Active Cavity Radiometer Irradiance Monitor (ACRIM) experiments show an upward trend in total solar irradiance of 0.036 percent per decade between the minima of solar cycles 21 and 22. The trend follows the increasing solar activity of recent decades and, if sustained, could raise global temperatures. Trends of total solar irradiance near this rate have been implicated as causal factors in climate change on century to millennial time scales.

Researcher Finds Solar Trend That Can Warm Climate
Ends debate over whether sun can play a role in climate change
Since the late 1970s, the amount of solar radiation the sun emits during times of quiet sunspot activity has increased by nearly .05 percent per decade, according to the study. “This trend is important because, if sustained over many decades, it could cause significant climate change,” said Willson, a researcher affiliated with NASA Goddard Institute for Space Studies and the Earth Institute at Columbia University, and lead author of the study recently published in Geophysical Research Letters.
“Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century,” says Willson. “If a trend comparable the one found in this study persisted during the 20th century it would have provided a significant component of the global warming that the Intergovernmental Panel on Climate Change report claims to have occurred over the last 100 years.”
Willson found errors in previous satellite data that had obscured the trend. The new analysis, Willson says, should put an end to a debate in the field over whether solar irradiance variability can play a significant role in climate change.
The solar cycle occurs approximately every 11 years when the sun undergoes a period of increased magnetic and sunspot activity called the "solar maximum," followed by a quiet period called the "solar minimum." A trend in the average solar radiation level over many solar magnetic cycles would contribute to climate change in a major way. Satellite observations of total solar irradiance have now obtained a long enough record (over 24 years) to begin looking for this effect.
......................
In order to investigate the possibility of a solar trend, Willson needed to put together a long-term dataset of the Sun’s total output. Six overlapping satellite experiments have monitored TSI since late 1978.The first record came from the National Oceanic and Atmospheric Administration’s (NOAA) Nimbus7 Earth Radiation Budget (ERB) experiment (1978-1993). Other records came from NASA’s Active Cavity Radiometer Irradiance Monitors: ACRIM1 on the Solar Maximum Mission (1980-1989), ACRIM2 on the Upper Atmosphere Research Satellite (1991-2001) and ACRIM3 on the ACRIMSAT satellite (2000 to present). Also, NASA launched its own Earth Radiation Budget Experiment on its Earth Radiation Budget Satellite (ERBS) in 1984. And, the European Space Agency’s (ESA) SOHO/VIRGO experiment also provided an independent data set during 1996-1998.
In this study, Willson, who is also Principal Investigator of the ACRIM experiments, compiled a TSI record of over 24 years by carefully piecing together the overlapping records. In order to construct a long-term dataset, Willson needed to bridge a two-year gap (1989-1991) between ACRIM1 and ACRIM2. Both the Nimbus7/ERB and ERBS measurements overlapped the ACRIM ‘gap.’ Using Nimbus7/ERB results produced a 0.05 percent per decade upward trend between solar minima, while ERBS results produced no trend. Until this study, the cause of this difference, and hence the validity of the TSI trend, was uncertain. Now, Willson has identified specific errors in the ERBS data responsible for the difference. The accurate long-term dataset therefore shows a significant positive trend (.05 percent per decade) in TSI between the solar minima of solar cycles 21 to 23 (1978 to present).

Abstract
We reconstruct environmental conditions of coastal Northwestern Florida from combined measurements of δ18O and Sr/Ca of fossil marine bivalves deposited in an archeological site during the late Holocene period. We first investigated the environmental controls of seasonally resolved records of δ18O and Sr/Ca of modern Mercenaria mercenaria and Mercenaria campesiensis collected live from five coastal sites along the east coast of North America. Seasonal profiles were obtained by sub-sampling the incremental growth layers of aragonite and were compared with in situ historical records of temperature and salinity. We show that these bivalves precipitate their shell in isotopic equilibrium with the water in which they grew and that the δ18O records are not affected by variations in growth rate. Winter growth appears to be interrupted or strongly reduced below water temperatures ranging from 7 to 18° C, depending on latitude. The annual average δ18O decreases with latitude, reflecting both the parallel trend of freshwater δ18O with latitude over the North American continent and the reduced winter growth rate. The Sr/Ca records of the 5 modern bivalves also exhibit seasonal variations can be correlated to water temperature. However, contrary to corals, the Sr/Ca ratio is considerably lower than the average sea water Sr/Ca composition and is positively correlated to the water temperature. We dated and measured the δ18O and Sr/Ca of 30 fossil M. campesiensis from an archeological site close to Cedar Key, in the Gulf of Mexico. Accelerator Mass Spectrometry 14C dates obtained for each shell show ages which cluster between 1100 to 1400 and 2300 to 2600 14C years BP corresponding approximately to two historical warm periods known as the Medieval Warm Period (~ 1300-900AD) and the Roman Warm Period (~ 250AD-200BC). The average annual and summer Sr/Ca of 4 fossil shells are higher than that of modern bivalves from the same location suggesting that annual coastal water temperatures were 3 to 4° C warmer than today. The bulk δ18O values show a marked trend towards more positive values. 24 fossil shells have bulk δ18O values 0.2\permil to 0.7\permil more positive than modern bivalves from the same location. These results suggest that the coastal waters off northwest Florida were warmer and less saline compared to today and attest of considerable differences of the regional climate and hydrological balance during the Medieval Warm Period and Roman Warm Period.

In 2007, Oreskes expanded her analysis, stating that approximately 20 percent of abstracts explicitly endorsed the consensus on climate change that: "Earth's climate is being affected by human activities". In addition, 55 percent of abstracts "implicitly" endorsed the consensus by engaging in research to characterize the ongoing and/or future impact of climate change (50 percent of abstracts) or to mitigate against predicted changes (5 percent). The remaining 25 percent focused on either paleoclimate (10%) or developing measurement techniques (15%); Oreskes did not classify these as taking a position on contemporary global climate change.[3]

Laws change mate, and every scientists will agree with the notion that nothing is 100%. furthermore these 'laws' are often very limited int heir scope and application. As your source states:
As such, a law is limited in applicability to circumstances resembling those already observed, and is often found to be false when extrapolated. Ohm's law only applies to constant currents, Newton's law of universal gravitation only applies in weak gravitational fields, the early laws of aerodynamics such as Bernoulli's principle do not apply in case of compressible flow such as occurs in transonic and supersonic flight, Hooke's law only applies to strain below the elastic limit, etc.
Just because AGW is not considered LAW does not mean it should be ignored.
first off the parallel to holocaust deniers is so incredibly funny.
now back to reality, i did not realize that there was no debate on the issue.
i don't think we should do anything that harms people. i dont knwo where you got that idea.
Finally, once again, for me to believe that AGW is not real i would need to see a scientific consensus. got one of those around?

The remaining 25 percent focused on either paleoclimate (10%) or developing measurement techniques (15%); Oreskes did not classify these as taking a position on contemporary global climate change.[3]

Consensus: a collective of OPINIONS. How hard is this? No wonder alarmists are typically collectivists philosophically. And I thought the neocons / republicans were sheeple.

Reread your own citation. It shows were each Law doesnt apply in different scenarios, conditions. Your citation is irrelevent.
first off the parallel to holocaust deniers is so incredibly funny.

Are you insinuating that the 'deniers' label wasnt propaganda by the alarmist consortium to discredit AGW skeptics?
now back to reality, i did not realize that there was no debate on the issue.

If youve been following this issue closely for the past 3+ years you'd know that the bigshots like Al Gore, Hansen, Mann, et al have been saying this for some time.

I showed you the scientific body's takes on the matter, you ignored it.

I glanced at the wikipedia summarization as it is today. Noticed afew new ones listed, sure enough groups formed around the climate issue. Hardly impartial. Dont have time right now to in-depth compare changes in independent groups on my original listing.

I also showed you how flawed the idea of a collctive of opinions is, but you wont budge. You have faith in their opinions. So I begged for some real numbers and what to do about them. Still waiting. I'm trying to be fair here.

Ok. Fair enough. I guess Wilson rocks your socks and that is enough. Oh, and now its water vapor too. Of course. So water vapour warms but cools. Ok. In a constant feed back cycle that gets warmer but then cools. Ok. Sure. So why the increase in temp trends?
Oh. I get it, Solar, more water vapor that warms but makes clouds that cool, but its still warmer!

Considering too, that we are at solar minimum, the planet is not cooling.
Surprise In Earth's Upper Atmosphere: Mode Of Energy Transfer From The Solar Wind

"Its like something else is heating the atmosphere besides the sun. This discovery is like finding it got hotter when the sun went down," said Larry Lyons, UCLA professor of atmospheric and oceanic sciences and a co-author of the research, which is in press in two companion papers in the Journal of Geophysical Research.

Change your clothes in a way throughout the day that reduces the amount you need to do laundry? Shower less than every single day? Installed power strips / surge protectors all throughout your home / work and manually cut the power to devices while not in use (most devices still suck power after you hit the power button)? Built and installed a solar hot water heater to replace your energy / fossil fuel sucking water heater. Ride a bike / walk to store / bar on a regular basis. Built fresnel lens solar stove for cooking, other means of cooking that use less fuel than a range? and some others i cant think of right now.

I hope to see the numbers I keep asking you for. I really do hope you actually know them as worried you seem to be about all of this.

That's what the "in chief editors" and the "councils" of those scientific groups WANT you to think...
We have had several threads throughout the years which shows the truth... Most scientists in those scientific groups DISAGREE with the AGW claims, some disagree more than others, and there are other differences in the disagreements, but yes, in short most scientists in these groups DISAGREE...
There was a thread i posted not too long ago about this exact same thing.

This I cannot answer. However, the belief that we contribute is still there and still supported so my support of the issue stands.
you offer:

This is in the article I cited. Refer to my first quote from this article this is exactly what it says. So I fail to see your point citing it or stating it is a new analysis....
Please see my cited information again. Try to ignore what a Scientific Consensus is all you want, it still exists.
What it shows is that the type of law you are referring to is severely limited. as your cited source states:
Scientific theories are generally more complex than laws; they have many component parts, and are more likely to be changed as the body of available experimental data and analysis develops.
furthermore scientific laws can and do CHANGE for example: Newton's Laws of Motion
You are denying man made global warming correct?
how is it in anyway shape or form equivalent to you comparing us 'alarmists' to holocaust deniers? don't even try to wriggle out of that one mate.
Okay man, clear this up. you have said repeatedly that there is NO CLEAR CONSENSUS and the DEBATE on AWG continues. You Also say the 'alarmists' are preventing debate. So which is it?
Reduce Consumption. Reduce Pollution. Two real easy ones.
Show me a list of these 9100 PhDs. No show me the list of the 31,000 you originally cited. Who are they? What did they study in school? What do they do for work now? It is not my place to disprove anything you have not even attempted to prove.
Which scientific communities?
These have released statements supporting the consensus:

Your going to need to do some real work to find a more reputable and sizable list of scientific bodies and groups who disagree with AGW....
because there is no 100% proof positive evidence of global warming some how eliminates the value and worth of the scientific communities consensus on AGW is your own choice to live in a box. Your problem not mine.
The infowars article is good fantasy reading, thanks for that. Who were the 650 scientists? how many scientists are members of the MASSIVE list in support of AGW? ya...

answers in order:
yes, nope, yes, yes, nope (yuck), yes, yes, yes (none), yes, yes, yes, yes, yes, yes, nope.... I do a LOT to limit my impact man, a lot....
