Are you really going to make me reply to all of this because you didn't bother to actually read the OP? :|
{ A leading conservative supporter of climate change denial is paying for their papers, isn’t that nice? }
They paid for two highly cited papers so everybody could read the full text verbatim. AWFUL. THE THUGS. THE BUFFOONS.
& you bolded all of the insignificant parts to try to push your narrative, you're so obnoxious.
{ To which aspects of the science of human-induced climate change are they referring? Are they proposing that it is unclear whether carbon dioxide is a greenhouse gas? Or that the concentration of carbon dioxide in the atmosphere has increased since direct measurements began in 1958? Or that global average temperatures in 2012 are greater than they were in 1900? If so, it would be intriguing to discover the basis for these claims of uncertainty. }
I've literally addressed every single one of these questions in the OP. These are the questions the AGW debate surrounds. We do know that CO2 is a greenhouse gas, we know it has increased, we know the temperature is hotter now than in 1900, we DON'T KNOW that CO2 is the CAUSATION of that last claim. I already posted the graph which illustrates this.
CO2 doesn't even correlate to the temperature increase anymore. It only did for a brief period of time, from the 80s to the early 00s. You can see that on the graph that was a 25 year warming period following an observational wave pattern of rising and falling temperatures.
As the reply says:
{ The issues have always been whether and to what extent changes in the climate are caused by changes in greenhouse gas concentrations and whether there is a causal, not simply correlative, link. For mere correlation (to the extent that it exists) does not necessarily entail causation. Thus, Legates et al.’s (2013) assertion that the science [of climate change] is indeed uncertain owing to
incomplete and complicated observational evidence is true. }
{ They just finished defending themselves on their claim of uncertainty from previous papers and they complain that Cook’s algorithm reported their papers as “being uncertain” (I bet the Heartland Institute didn’t like that!) }
For Christ's sake it's almost like you're reading everything out of context on purpose. We are uncertain about the actual anthropogenic effect on climate change. The individual papers by Legates and Swoon, which were rated "uncertain" by Cook, took a very clear stance that they are opposed to a majority-anthropogenic cause. Yet they were listed as "uncertain" so as to not effect Cook's numbers. That's the scam he consistently pulls.
How you even came to the conclusion that this sad excuse of a "study" agrees with Cook is beyond me.
{ Legates et al. For example, Doran and Zimmerman (2009) sent a
2-min online survey to 10,257 Earth scientists at universities and government research
agencies. Of the 3,146 respondents (a 31 % return rate), only 5 % identified themselves as
climate scientists and only a mere 79 (2.5 %) listed ‘climate science’ as their area of
expertise, having published more than half their recent peer-reviewed papers on climate
change. Of these 79 respondents, 98 % believed human activity was a significant contributing
factor in changing mean global temperatures. }
So of 79 public/government climate scientists who answered a 2 minute online survey, 98% of them said humans are a significant factor in climate change.
THE SCIENCE IS SETTLED EVERYONE, WINDY GOT IT ALL SORTED OUT FOR US!!
& then you criticize the person who points out that this two minute online survey is not a legitimate way of measuring scientific consensual about a nuanced and intricate climate issue, like that's the most absolute ridiculous thing anybody could say about a two minute online survey. Are you serious rn?
{ The unquantified definition: ‘‘The consensus position that humans are causing global warming’’ (p. 1),
The standard definition : As stated in their introduction, that ‘‘human activity is very likely causing
most of the current warming (anthropogenic global warming, or AGW)’’ (p. 2), }
Those are two completely different definitions and you're DEFENDING the guy who tried to pull a bait and switch with them.
You are truly a gem.
{ and found only 41 articles that explicitly supported AGW as opposed to Cook et al’s data which found 64. }
64 is the actual number of studies that explicitly endorse AGW that Cook originally found. It represents .3% of the total number of papers he started with. In order to reach the 97% consensus, he took those .3% of papers and added them to the few hundred papers that less explicitly states that humans are probably more of the reason for climate change than not. He then SUBTRACTED nearly 8,000 papers (from the original pool of ~12k) which explicitly took NO stance. aka "we don't know enough to call it one way or the other", which I showed in the OP was actually the scientific consensus regarding AGW.
Legates went further through the 64 papers Cook designated "explicitly endorses AGW" and found only 41 actually did, further reducing the .3% stat of scientists who actually explicitly endorse AGW.
Now all of you look closely at my bolded text.
{ Shortly after pointing that mistake Legates et al. Pretend to re-crunch the numbers and spit out 0.3% “after their adjustment” ONLY after including all 11944 papers, of which more than half were removed for being neutral to climate change. How fuken sly is that? }
no nigga that's what Cook did. He started with a pool of 11944 papers. He grouped them into 7 levels of endorsement, with 4 being neutral. These are John Cook's own results (edit to include John Cook's own descriptions of each Level):
Level 1 = 64 → Explicitly states that humans are the primary cause of recent global warming.
Level 2 = 922 → Explicitly states humans are causing global warming or refers to anthropogenic global warming/climate change as a known fact
Level 3 = 2910 → Implies humans are causing global warming. E.g., research assumes greenhouse gas emissions cause warming without explicitly stating humans are the cause
Level 4 = 7970 → Does not address or mention the cause of global warming, expresses position that human's role on recent global warming is uncertain/undefined
Level 5 = 54 → Implies humans have had a minimal impact on global warming without saying so explicitly E.g., proposing a natural mechanism is the main cause of global warming
Level 6 = 15 → Explicitly minimizes or rejects that humans are causing global warming
Level 7 = 9 → Explicitly states that humans are causing less than half of global warming
He discarded Level 4, the neutral/no stance. He combined Levels 1+2+3, compared that to the combination of 5+6+7, and said LOOK 97% OF SCIENTISTS ARE IN A CONSENSUS THAT AGW IS REAL!! Level 3's description admits that those 3000 papers DON'T ACTUALLY STATE HUMANS ARE THE CAUSE, yet he INCLUDED THEM IN THE POOL OF PAPERS THAT EXPLICITLY STATE HUMANS ARE THE CAUSE. The actual scientific consensus is Level 4, humans role on recent warming is UNDEFINED/UNCERTAIN. Yet NASA, the IPCC, every government agency pushes this crooked ass John Cook 97% consensus propaganda because people like you buy into despite having the evidence right in front of your face.
Would you like any further reading comprehension assistance or are we good here?
You woke me up from my Saturday afternoon nap for this bullshit.
