I have one question and one only.
Why is the Great Barrier Reef, our national treasure, or one of them, why is it 25% of the size it was in1985 and what is the cause ?
False. It's unprecedented, and occurring when the planet should be cooling.The current rate of warming is actually not unusual.
False. I know of none, but please enlighten us with those you know.This is actually something which all climate scientists agree with!
True. The media seldom quote the actual science.It is a media/social media myth...
False. Climate is a response to a very simple energy balance equation. How climate propagates at the surface of the planet has many variables.What affects climate change is very complicated.
False. There is no evidence of climate changing contrary to irradiance and CO2 attributions, and no credible evidence that warming rates have been more rapid.The climate has always changed to a large extent and to rates as fast and faster than the current rate.
False. The scientific probability of AGW being true is now calculated at 99%. The IPCC calculated it at 95% 5 years ago.It is true that most climate scientists now say that humans are causing the majority of the current climate change ..., but in reality we just don't know, and so far we haven't pushed the climate outside the normal, natural rate or limits.
I know of many false attributions from science deniers, so please enlighten me on all these alarmists who can be considered credible in science circles....alarmists (seriously, you don't know what a climate alarmist is? Keep up!) are further from facts and reality than the deniers....
So far there is little you have stated that is credible - your understanding of climate science is not even at primary school level.Yet amusingly, people like you still say I exhibit every tendency of the climate denier!
Given your claims to date, you are delusional....I guarantee that I know a heck of a lot more about it than you ever will. I've worked professionally with climate scientists, I'm a qualified scientist myself, I've worked on projects directly related to climate science and environmental science.
Mere opinion from a non scientist on a topic which is about survey methodologies and the probability their findings have merit. Nothing guarantees the underlying science as falsifiability is its bedrock.An insightful presentation on the mythical consensus also featuring some interesting comments on manipulation of statistics and exploitation of human psychological traits in agenda pursuit
The problem is that data is relevant to science! And even more problematic is that some have arrived at conclusions that are not logically justifiable based upon the raw data.Mere opinion from a non scientist on a topic which is about survey methodologies and the probability their findings have merit. Nothing guarantees the underlying science as falsifiability is its bedrock.
Again, climate science deniers dig deep into irrelevances for their ill informed ideas.
No! I never said 97% of scientists are wrong! Nor did I say that 97% of scientists are right!The problem is that data is relevant to science! And even more problematic is that some have arrived at conclusions that are not logically justifiable based upon the raw data.
So 97% of all scientists are wrong ? And the IPCC since 1993 has been spot on with its science based predictions. They are wrong as well ... all 24,000 of them. Of the 50,000 who agreed with the 2017 report, all of them .... are not logically justifiable based upon the raw data ... and have ... departures from logic. In your opinion.
Golly. An interesting theory.
Sorry but at this point, I would bother with a reply, but the melting snowman convinced me its pointless.
Frosty has convinced me its all fake !! Why does that yellow puddle smell ? Why is that man ORANGE ?
It's not only the fact that a lot of scientists have voiced disagreement, it is the logical flaws in Cook's approach to, and interpretation of, the collation of data.
Would you care to explain how 34% agreement, based upon interpretaion of abstracts from approx. 12,000 papers, were somehow transmuted into a near absolute consensus?
It would seem that some people's idea of the definition of 'bs' is anything that disagrees with their chosen opinion.
It would also seem that those same people believe science to be defined as anything that agrees with their chosen opinion.
I just looked at the paper again to make sure of the facts! The figure may be found in table 3.
34.8% of authors endorse CAGW.
Who exactly do you claim is lying now!?
Edit: 34.8% of authors endorse AGW
Not CAGW as previously posted.
That figure was based upon the assessment of the paper abstracts using specific criteria to determine whether there existed, implicit or explicit, endorsement or rejection, or no position taken.
Based upon your postings, one could be forgiven for thinking that you have probably only read the abstract for Cook's paper. Please do me the courtesy of reading the entire paper before replying to this post!!
The conclusions of the other 64.8% authors, based upon their paper abstracts alone, most certainly did not contain the requisite 62.2% (i.e. 97 - 34.8 = 62.2) endorsement.
In fact, the majority (>60%) of the papers/authors (those assessed as having taken no position on AGW), were subsequently (and conveniently) excluded from the final calculations. Hence the totally bogus results.
And let's not forget that none of the endorsement criteria required a catastrophic perception of AGW.
But if an apocalyptic fantasy has become so important that the published facts no longer matter, well I believe that there may still exist, some specialised facilities, designed to cater for those who are no longer able to remain engaged with reality.
Huh!??
About what exactly?!!
Was I wrong about that, 34.8% of authors AGW endorsement, figure in table 3 of Cook's paper?
I made no implications about the >60% no position, other than it was incorrect to discount them in the final calculation.
It might not even be possible to know whether an absence, or presence, of endorsement by those authors exists, without further clarification from the authors themselves.
Of the 1200 authors who replied to a self assessment invitation, the level of AGW endorsement was higher, but still fell a long way short of the 97%.
Again I reiterate only 34.8% author endorsement, was discovered, based upon the abstracts.
The findings cannot support Cook's claim to the existence of a 97.1% scientific consensus for the simple reason that he doesn't have a sound basis for claiming to know what the AGW position of the 60+% of papers and authors (excluded from his tally) would have been.
Even if he had treated the 1200 self assessment responses as a crosssection for statistical purposes, the results would still fall 30+% short of the mark.
Cook was clearly either being incompetent or dishonest in his conduct when producing that paper.
Still totally overlooking the key point!
The same creative argument could be put forward about whether or not water is wet!!
The obvious shortcomings of Cook's approach are no excuse for presenting a dodgy result.
The research findings in Cook's paper cannot logically support his claim to the existence of the purported 97% consensus for the simple reason that 60+% of the authors/papers were excluded from the final calculation!
This convenient claim to the effect that "everybody believes, so therefore it's okay to presume roughly 60% were probably largely agreeable" is utter nonsense which has no place in the true practice of science.
Still missing the point!
What you are highlighting is the fundamental and logical flaw in Cook's approach to discovery/confirmation of consensus (or lack thereof).
He assumed that a consensus existed and then used that assumption to justify his exclusion of 60+% of the collated data from consideration, thereby biasing the results in favour of his opinions, and defeating the entire point of the exercise!!
This is getting lamer and lamer.
His paper is unable to demonstrate the widespread claims to the existence of near absolute scientific consensus of catastrophic AGW for several reasons.
One of those reasons is the assessment criteria don't require subscription to the catastrophic viewpoint for inclusion in AGW endorsement.
A further reason is that the search criteria were limited to the point that only 11,944 (of 12,465 papers originally selected) were entered into consideration. By Cook's own admission "11,944 papers is only a fraction of climate literature".
The method was demonstrably subjective in relation to the assessment of the abstracts. 33% of the endorsement ratings failed to achieve consistency, prior to allowing communication between those "independent" assessors with 16%, endorsement rating disagreement remaining thereafter.
The 14% response to self assessment, produced vastly different results, further demonstrating the shortcomings of the abstract assessment methodology.
And to top it all off, Cook then decides that it's okay to ignore the 60+% no position papers, because he likes to somehow believe that most of them would endorse AGW!!!
Now one can construct as many inapt analogies as one likes, around widely agreed scientific viewpoints on tectonic plates and solar temperature, but they are irrelevant to catastrophic climate change, etc. for the simple reason that widespread uncertainty and disagreement is evidenced by the heated disputes that continue to emerge from many members of the scientific community.
There you go again totally misconstruing what I was saying in a vain attempt to defend your precious 97% illusion!
34.8% does not a consensus maketh!!
No they didn't say anything about "screwing up the place"! That wasn't in the criteria!!
Stop making stuff up to suit yourself and read the FTSEing paper fully!
34.8% of authors AGW endorsement was all Cook found!!!
It's there in black and white in table 3 of his paper!
34.8% is over 60% short of 97%, for the simple reason that he chose to dismiss a similarly huge chunk of data, because, like yourself, it didn't suit his FTSEing religion!!
You cannot count 97 to 98% of no positions as yes, but Cook has effectively done that!
34.8% of authors, based upon Cook's assessment of abstracts, endorsed AGW.
Those are facts that I understand perfectly well!
Then his conclusions cannot support the claim that 97% of scientists are in agreement with his purported AGW consensus, because he only counted 35.4% of them!!!
That is in black and white!!!
His conclusions could only be valid, if he could somehow demonstrate that those scientists, not recognised as holding an AGW position, were somehow in roughly 97 to 99% agreement with the AGW hypothesis.
He hasn't done that!!
He simply tried to justify his conclusions by opining that they probably were!
And by the way, your whale analogy from a post or two ago makes no sense to me whatsoever. I don't even understand how it could possibly relate to my logic. This comes as no great surprise since this dialogue has alerted me to the fact that your concept of logic is clearly very different from mine.
Religious zealots often hold that perception of heretics.
34.8% AGW endorsement by author, is all that could honestly be claimed to have been found in that study. And even that result is somewhat dubious to those whom cared enough to read past the paper's abstract.
But it seems that those sharing in Cook's religious zeal, do like to perceive it very differently.
So you have some idea that, for example, it makes no difference that temperature data have been recorded at different times of day. Please explain what makes it logical to use data which is inhomogeneous.The problem is that data is relevant to science! And even more problematic is that some have arrived at conclusions that are not logically justifiable based upon the raw data.
True. Unfortunately you do not appreciate how climate science data is validated. You should read some of Thomas Karl's papers to get an idea of the reasons for data homogenisation, and the methodologies that have improved data reliability over timeOne doesn't need to be a scientist to recognise departures from logic, impartiality and the correct application of mathematics.
I guess you will find yourself guilty.Those promoting studies guilty of aforementioned failings, do themselves and their credibility enormous disservice.
No opinions were sought.I have examined the "paper" authored by Cook et al. which sought to assess, via examination of abstracts, the opinions of approximately 12,000 scientists on anthropogenic climate change.
The posts, to which you are replying, relate to the argument surrounding the purported scientific consensus, and not to temperature measurements.No opinions were sought.
I read all your previous comments.
I can see clearly see what you think you know.
You should study logic and probability (and science elsewhere) before making statements which needed to be based on sound reasoning.
I posted separately in reply to your separate posts on different topics, yet you have confused these into one.The posts, to which you are replying, relate to the argument surrounding the purported scientific consensus, and not to temperature measurements.
If that were true, then your ability to use this knowledge is deficient. You consistently misrepresented Cook's data.I can assure you that I am quite well versed in the application of logic and probability theory.
If that were true, then it wouldn't be too difficult for someone to identify errors in my representations on the matter.I posted separately in reply to your separate posts on different topics, yet you have confused these into one.

Let's not argue. People will believe what they want to believe.
Meanwhile Behring sea isn't frozen this winter:
Humans are living through a dramatic transformation of the planet's surface due to climate change, with the most obvious sign being the rapid decline in Arctic sea ice. And now, imaging has revealed perhaps a new chapter in that decline: The Bering Sea, which under normal circumstances should remain frozen-over until May, is almost entirely free of sea ice in early April.
Part of what makes this event so stunning, as the National Oceanic and Atmospheric Administration (NOAA) pointed out in a statement, is that the Arctic sea ice should be reaching its annual maximum right now. The summer reduction in sea ice normally only begins around now. And that process has, throughout recorded history, left the region between Russia and Alaska frozen at this time of year. But 2019 already has the lowest Arctic sea ice extent on record (beating 2018, which was also a record-breaker). And that's manifesting in an unseasonably liquid sea off Alaska's northwest coast.
