Not 97% but .3% of Climatologists agree.

a. watts was not the scientist I was referencing...

b. oh therefore it will be easy for you to link to the "extensive scientific evidence"....


please note...

1. you would have to establish there was some warming outside natural varibility.

2. there was some sort or warming different from previous periods of warming... which were not smoothed away by data manipulation.

3. that man made co2 caused it...

4. finally that this peer review paper was incorrect...

http://wattsupwiththat.com/2013/09/...ven-by-a-new-paper-showing-major-math-errors/


A major peer-reviewed paper by four senior researchers has exposed grave errors in an earlier paper in a new and unknown journal that had claimed a 97.1% scientific consensus that Man had caused at least half the 0.7 Cº global warming since 1950.

A tweet in President Obama’s name had assumed that the earlier, flawed paper, by John Cook and others, showed 97% endorsement of the notion that climate change is dangerous:

“Ninety-seven percent of scientists agree: #climate change is real, man-made and dangerous.” [Emphasis added]

The new paper by the leading climatologist Dr David Legates and his colleagues, published in the respected Science and Education journal, now in its 21st year of publication, reveals that Cook had not considered whether scientists and their published papers had said climate change was “dangerous”.

The consensus Cook considered was the standard definition: that Man had caused most post-1950 warming. Even on this weaker definition the true consensus among published scientific papers is now demonstrated to be not 97.1%, as Cook had claimed, but only 0.3%.

Only 41 out of the 11,944 published climate papers Cook examined explicitly stated that Man caused most of the warming since 1950. Cook himself had flagged just 64 papers as explicitly supporting that consensus, but 23 of the 64 had not in fact supported it.




Quote from futurecurrents:

Oh, you mean the TV meteorologist Watts?

This is what the American Meteorological Society says..


"It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide." (2012)7
 
So it appears the Associated Press has discovered what conservative and libertarian economic critics have been saying all along: top-down government regulation to promote "green energy" has numerous unintended consequences, including negative repercussions for the environment.

mmm.... I've been around more then a half century and I didn't notice any "Rapid change in the Climate".

....are you talking about that alleged .5 degree Celsius ??
 
Quote from futurecurrents:

Okay, so is everyone clear that CO2 molecules absorb and re-radiate heat that would otherwise pass through the air unimpeded?
Only in small closed glass jars. On the surface of very large spheres covered with a complex system of gases and weather, not so much.

So you are saying that the physical properties of the CO2 molecule is dependent upon whether it is within a glass jar, or a tube or the atmosphere?

Because if so, you are wrong.

The properties of CO2 reaction to heat is at the molecular level. The molecule does not care where it is, nor with how many other CO2 molecules are around it.


This is also a very important concept. Before we can move on it must be understood.

I imagine the properties are the same whether in a jar or a tube.
Now in a complex atmosphere of various temps and pressures....

The properties of CO2 reaction to heat is at the molecular level. The molecule does not care where it is, nor with how many other CO2 molecules are around it.
How about when oxygen, nitrogen, dust and Water molecules are "around it"?


This is also a very important concept. Before we can move on it must be understood.
I'm trying not to laugh...oops...I did anyway.

Must mean the record breaking cold temperatures that most of North America is experiencing this week.


:cool:
 
1. are you also clear that in the upper atmosphere of the earth co2 repels energy causing heat... thereby promoting cooling?

I can quote the NASA experiment for you again.

2. please read this link at your agw nutter al gore sponsored website....

study... "climate sensitivity."


and read the last sentence...


"In truth, nobody knows for sure quite how much the temperature will rise, but rise it will. Inaction or complacency heightens risk, gambling with the entire ecology of the planet, and the welfare of everyone on it."

this is a stunning but truthful admission from the nutters website...
I have to give credit to the web master for having some integrity.

Net positive feedback is confirmed by many different lines of evidence.

Climate Myth...
Climate sensitivity is low
"His [Dr Spencer's] latest research demonstrates that – in the short term, at any rate – the temperature feedbacks that the IPCC imagines will greatly amplify any initial warming caused by CO2 are net-negative, attenuating the warming they are supposed to enhance. His best estimate is that the warming in response to a doubling of CO2 concentration, which may happen this century unless the usual suspects get away with shutting down the economies of the West, will be a harmless 1 Fahrenheit degree, not the 6 F predicted by the IPCC." (Christopher Monckton)


Climate sensitivity is the estimate of how much the earth's climate will warm in response to the increased greenhouse effect if we double the amount of carbon dioxide in the atmosphere. This includes feedbacks which can either amplify or dampen that warming. This is very important because if it is low, as some climate 'skeptics' argue, then the planet will warm slowly and we will have more time to react and adapt. If sensitivity is high, then we could be in for a very bad time indeed.

There are two ways of working out what climate sensitivity is. The first method is by modelling:



Climate models have predicted the least temperature rise would be on average 1.65°C (2.97°F) , but upper estimates vary a lot, averaging 5.2°C (9.36°F). Current best estimates are for a rise of around 3°C (5.4°F), with a likely maximum of 4.5°C (8.1°F).

The second method calculates climate sensitivity directly from physical evidence, by looking at climate changes in the distant past:

adapted fig 3a

Various paleoclimate-based equilibrium climate sensitivity estimates from a range of geologic eras. Adapted from PALEOSENS (2012) Figure 3a by John Cook.

These calculations use data from sources like ice cores to work out how much additional heat the doubling of greenhouse gases will produce. These estimates are very consistent, finding between 2 and 4.5°C global surface warming in response to doubled carbon dioxide.

It’s all a matter of degree
All the models and evidence confirm a minimum warming close to 2°C for a doubling of atmospheric CO2 with a most likely value of 3°C and the potential to warm 4.5°C or even more. Even such a small rise would signal many damaging and highly disruptive changes to the environment. In this light, the arguments against reducing greenhouse gas emissions because of climate sensitivity are a form of gambling. A minority claim the climate is less sensitive than we think, the implication being we don’t need to do anything much about it. Others suggest that because we can't tell for sure, we should wait and see.

In truth, nobody knows for sure quite how much the temperature will rise, but rise it will. Inaction or complacency heightens risk, gambling with the entire ecology of the planet, and the welfare of everyone on it.
