SPEAKING OUT
A system is in place that makes it incredibly difficult, almost impossible, for scientists to take a public stance against AGW — their funding and opportunities are shutoff, their credibility and character smeared, and their safety sometimes compromised.

Example: In 2014, Lennart Bengtsson and his colleagues submitted a paper to Environmental Research Letters which was rejected for publication for what Bengtsson believed to be “activist” reasons.

Bengtsson’s paper disputed the uncertainties surrounding climate sensitivity to increased greenhouse gas concentrations contained in the IPCC’s Fourth and Fifth Assessment Reports.
I have been put under such an enormous group pressure in recent days from all over the world that has become virtually unbearable to me. If this is going to continue I will be unable to conduct my normal work and will even start to worry about my health and safety. I see therefore no other way out therefore than resigning from GWPF. I had not expecting such an enormous world-wide pressure put at me from a community that I have been close to all my active life. Colleagues are withdrawing their support, other colleagues are withdrawing from joint authorship etc.

I see no limit and end to what will happen. It is a situation that reminds me about the time of McCarthy. I would never have expecting anything similar in such an original peaceful community as meteorology. Apparently it has been transformed in recent years.

From Mr Science's link:
If you still believe in the 97% consensus then by all means find the list of 2,748 scientist that have zero doubts regarding the IPCC’s catastrophic conclusions on Climate Change (given I’ve found 85 names effectively refuting the claims, that’s the minimum number required to reach the 97% consensus).
Ok, that's easy.
https://whatweknow.aaas.org/
There, the AAAS represents 120,000 scientists who support the science reported by the IPCC on climate change.

larue, you're going to have to better than 85 names if you want to argue that the consensus is not 96% or 99%.
I'd suggest you start here.
list of science deniers

Of course you'll have to separate those who are actual scientists from the hacks, lobbyists, weirdos and wingnuts from that list.
Most of larue's star witnesses are already questionable, like Dr Roy Spencer, a believer of intelligent design who is paid by the oil industry's Heartland Institute.
Good luck, you'll need it.

The real world has benefited greatly from the scientific method based upon unbiased testing of hypothesis and rejection of hypothesis when experimental data does not fully support the hypothesis...
And that is exactly what is happening. But sure, keep on believing that all those scientists are suppressing information for a political agenda.

Absolutely not (though you seem to have no problem doing so for Trump and Fox News).

The great thing about the IPCC and all other scientific studies is the data is published so you can study it at your own leisure.

Oh you mean suppressing information such as

a) the dominance of water vapor as the primary greenhouse gas
b) the diminishing returns of absorbance with increasing concentration. Absorbance is logarithmic
c) the 2000 to 5000 ppm of CO2 in the past which included ice ages
d) Temperature increases determined in antarctic ice cores predate co2 increases by 500-800 years

Ok I will be on the look out for that
Oh Wait... already happened!

Michael Mann seemed to feel it was OK to suppress the medieval warming period
John Cook seems to feel it OK to mislead the world with the 97% survey
& then there is Phil Jones who seems to think he can redefine the peer review process

yeah, no political agenda there at all

Odd how you are now claiming the puedo science is fully in compliance with the rejection of hypothesis when experimental data does not fully support the hypothesis.
Yet a few posts ago you were trying to justify
"a reasonably successful theory is not replaced unless there is a more successful theory presented."
Post # 55
And a few posts latter
The clear majority conclude that human produced CO2 is playing a significant role in the current warming pattern the Earth is experiencing. Which option do you think...actually, we know that. let me rephrase. What option would rational people think makes more sense.
Post # 64

Your positions in post # 55 and posts # 64 are completely at odds with the proven scientific model of "the rejection of hypothesis when experimental data does not fully support the hypothesis." post # 85

Real Science also requires consistency or at the very least an explanation of which of the inconsistent statements you no longer believe hold true

Apparently since current CO2 is 400 ppm and Co2 was at least 5-10X that level, a rough estimate would be a 5-10 fold increase in the worlds population.
Unless you want to argue the laws of physics were different back then

Space, food and fresh clean water will a problem of coarse long before we reach those population levels, but lets deal with the currently proposed apocalypse first

None of those would explain why we are experiencing a rise in global temperatures with the rise of CO2 we are experiencing.
You have no explanation for what is happening.

250 million ago with dinosaurs roaming the earth CO2 levels were about 5 times what they are now and the planet was undergoing a thermal maximum.
Do you want to put the planet in another thermal maximum?

Just because its happened before doesn't make it a good idea to do it again.

I never said that at all
I never said anything about 10C higher because that is not at all predicted by the physics
a 10C increase is your mistake

You asked about the ability of humans to survive @ higher CO2 levels
As I pointed out a few times absorption of Infared radiation by CO2 (all molecules) is logarithmic




The carbon dioxide that’s already up in the atmosphere absorbs most of the infrared radiation it can. CO2 only “soaks up” its favorite wavelengths of light (less than 16% of infrared wavelengths) , and it’s close to saturation point. It manages to grab a bit more light from wavelengths that are close to its favorite bands, but it can’t do much more, because there are not many left-over photons at the right wavelengths.

the room you are in right now likely has a CO2 level well in excess of a 1,000 ppm
Submarine crews preform their duties at levels of 2,000-5,000 ppm .
Do you think the navy would allow men to run nuclear ballistic subs surrounded by elevated levels of a pollutant?



Somehow you seem to think since we are @ 400 ppm now then 2,000-5,000 ppm must be catastrophic.
It would be catastrophic if absorption was linearly dependent on concentration. It is not a linear relationship, it is logarithmic relationship


The first 20 ppm does almost all of absorbing. Most of the incremental CO2 beyond that does very little
No incremental absorption, no global warming

That explains why CO2 at levels of 2,000 to 5,000 ppm did not prevent ice ages
think about it
You do realize there were multiple ices ages in the earth's history when CO2 levels were well in excess of today levels , correct?

the physics & geological record just does not support the puedo-science of catastrophic global warming as per alarmists
a) the dominance of water vapor as the primary greenhouse gas
b) the diminishing returns of absorbance with increasing concentration. Absorbance is logarithmic
c) the 2000 to 5000 ppm of CO2 in the past which included ice ages
d) Temperature increases determined in antarctic ice cores predate co2 increases by 500-800 years

That's because water vapour is a feedback effect while CO2 and greenhouse gases are a forcing effect.
Water vapour levels only change with global temperature changes while CO2 changes cause global temperature changes.

From the IPCC.

Frequently Asked Questions
FAQ 8.1 | How Important Is Water Vapour to Climate Change?


As the largest contributor to the natural greenhouse effect, water vapour plays an essential role in the Earth’s
climate. However, the amount of water vapour in the atmosphere is controlled mostly by air temperature, rather
than by emissions. For that reason, scientists consider it a feedback agent, rather than a forcing to climate change.
Anthropogenic emissions of water vapour through irrigation or power plant cooling have a negligible impact on
the global climate.


Water vapour is the primary greenhouse gas in the Earth’s atmosphere. The contribution of water vapour to the natural greenhouse effect relative to that of carbon dioxide (CO2) depends on the accounting method, but can be considered to be approximately two to three times greater. Additional water vapour is injected into the atmosphere from anthropogenic activities, mostly through increased evaporation from irrigated crops, but also through power plant cooling, and marginally through the combustion of fossil fuel. One may therefore question why there is so much focus on CO2, and not on water vapour, as a forcing to climate change.

Water vapour behaves differently from CO2 in one fundamental way: it can condense and precipitate. When air with high humidity cools, some of the vapour condenses into water droplets or ice particles and precipitates. The typical residence time of water vapour in the atmosphere is ten days. The flux of water vapour into the atmosphere from anthropogenic sources is considerably less than from ‘natural’ evaporation. Therefore, it has a negligible impact on overall concentrations, and does not contribute significantly to the long-term greenhouse effect. This is the main reason why tropospheric water vapour (typically below 10 km altitude) is not considered to be an anthropogenic gas contributing to radiative forcing.

Anthropogenic emissions do have a significant impact on water vapour in the stratosphere, which is the part of the atmosphere above about 10 km. Increased concentrations of methane (CH4) due to human activities lead to an additional source of water, through oxidation, which partly explains the observed changes in that atmospheric layer. That stratospheric water change has a radiative impact, is considered a forcing, and can be evaluated. Stratospheric concentrations of water have varied significantly in past decades. The full extent of these variations is not well understood and is probably less a forcing than a feedback process added to natural variability. The contribution of stratospheric water vapour to warming, both forcing and feedback, is much smaller than from CH4 or CO2.

The maximum amount of water vapour in the air is controlled by temperature. A typical column of air extending from the surface to the stratosphere in polar regions may contain only a few kilograms of water vapour per square metre, while a similar column of air in the tropics may contain up to 70 kg. With every extra degree of air temperature, the atmosphere can retain around 7% more water vapour (see upper-left insert in the FAQ 8.1, Figure 1). This increase in concentration amplifies the greenhouse effect, and therefore leads to more warming.

This process, referred to as the water vapour feedback, is well understood and quantified. It occurs in all models used to estimate climate change, where its strength is consistent with observations. Although an increase in atmospheric water vapour has been observed, this change is recognized as a climate feedback (from increased atmospheric temperature) and should not be interpreted as a radiative forcing from anthropogenic emissions. Currently, water vapour has the largest greenhouse effect in the Earth’s atmosphere. However, other greenhouse gases, primarily CO2, are necessary to sustain the presence of water vapour in the atmosphere. Indeed, if these other gases were removed from the atmosphere, its temperature would drop sufficiently to induce a decrease of water vapour, leading to a runaway drop of the greenhouse effect that would plunge the Earth into a frozen state. So greenhouse gases other than water vapour provide the temperature structure that sustains current levels of atmospheric water vapour. Therefore, although CO2 is the main anthropogenic control knob on climate, water vapour is a strong and fast feedback that amplifies any initial forcing by a typical factor between two and three. Water vapour is not a significant initial forcing, but is nevertheless a fundamental agent of climate change

Are you saying you don't believe that there have been ice ages and thermal maximums or that there is any correlation between temperature and greenhouse gases?
The greenhouse effect is 150 years old now and nobody, including you or any of your deniers, has disproven it.

Apparently since current CO2 is 400 ppm and Co2 was at least 5-10X that level, a rough estimate would be a 5-10 fold increase in the worlds population.
The only time that has been the case was when early animals were evolving.

p.s. Do you see how stupid your hypocrisy is? You claim despite what so many scientists say about there evidence, you claim there isn't enough evidence to support anthropogenic CO2 as the major driver of current climate change but you throw out a ridiculously untested theory that the world could support 70 billion people. You also seem to ignore that for most of the time the Earth's atmosphere was in your ideal range of CO2, the average temperature was 10 C above now
(And actual scientists think a rapid change of only 2 or 3 C will be catastrophic to our society).

The rest of your post is just adding in other inconsequential facts to distract from how foolish your claims are.

What a stupid argument. You claim a bunch of well know facts are suppressed despite them being easily accessible and widely known to the people who study this stuff. That quite clearly shows you have a victim complex that is completely detached from any facts.

You should just admit that you don't like that even after knowing your 'suppressed' facts, people who study this stuff don't buy your bullshit and instead follow what science tells them.

p.s. If you base your scientific knowledge on a google image search, no wonder you have so much trouble with science.
