Totally untrue. If you look at the CO2 levels recorded on the top of Mauna Kea there is NO visible rise in levels at the time of Pinatubo or Iceland. For your statement re Pinatubo to have been true the atmospheric CO2 levels SHOULD HAVE DOUBLED in that time.
No significant change, apart from the normal man made year by year increase.
You are quoting from a scam email written by, and circulated widely and forwarded without question by deniers - and without thinking. Bringing into focus recent reports that they may have difficulty in that area.
Further, irrespective of what nature emits, mankinds CO2 emmisions are on top of that, and are new.
The skeptics are wrong. We don't know everything, but sure as hell there are limits to growth. When CO2 levels acidify the seas such that fish & coral die, is that ok? Do we do it just till we need to carry respirators? Then it will be just us and the cockroaches.
Wouldn't science, scientists, and all the rest of us be better served if these sixteen and all the others in the scientific community would focus on designing better experiments to test the different global warming theories?
Certainly there is a political dimension to the issue, and an economic one, and scientists are entitled to have an opinion on these issues. But they seem to be an aside to the scientific problems -- which is where these men's expertise lies.
It seems that the majority of US engineers are clueless about global warming. The people who wrote the letter appear to be the usual mix of emeritus professors and people from other scientific endeavors - using their name to give themseolves some credibility.
80% of engineers in the UK say that global warming is real and only 10% do not. Thye don't have a continuous drumbeat from the ignorant press and Republicans.
Engineers in the US don't keep up to date with what is going on on the rest of the planet.
The entire CO2 debate (NOTE: There has never been an honest debate, under oath - only a 50 billion propaganda campaign sponsored by some "not so honest people"!
Just apply a little common sense, such as the WSJ article, and do your own "thorough" investigation - not difficult to do!
First, what are the two most important events for creating "all life on earth"?
The SUN & the wonderful trace gas CO2.
I have asked >50 people about "how much of the astmosphere is represented by CO2" & the answers ranged from a low of 3 % to 60 %? The actual is that all CO2 in the atmosphere is 0.04 % (their term is 390 parts/million) or 1 part in every 2500 parts! Also, remember that "water vapor" is 25 times more (1.0 %) abundant & creates the heat trapping clouds
A interesting science experiment would be to heat all the earth's Co2 & spread evenly back into the atmosphere - and there would "probably" be "NO TEMPERATURE CHANGE"!
Much more common sense (the internet has volumes of honest data - concentrate on some of the older info generated when science was factual); but we really need an honestd debate, under oath, to resolve this controversy!
What is a scientist doing writing an op-ed in the Wall Street Journal rather than in the pages of the scientific journals publishing the papers discussing global warming? As Happer states in his op-ed, this is not the way science is supposed to work.
If you search for Happer in Google Scholar, you'll see that he has not published any research supporting his contentions that global warming is controvertible or that CO2 is not a greenhouse gas or that increasing greenhouse gas concentrations do not increase the energy of the earth's climate system thus forcing changes to achieve a new equilibrium. In fact his scant discussion of CO2 leaves completely undiscussed that last issue and its consequences, such as increased extreme weather. The question must be asked why?
I think that his closing paragraph sums up his real concern, and it is about corruption of the policy process, such as that which pushed for cap and trade as a free market answer, not that global warming is not occuring. For one, free market theory is a failed theory, as proven by the existence of bubbles and financial crises, and using it to serve to ameliorate human activity would more than likely result in a few gaming the system to their benefit without reducing greenhouse gas emissions and slowing global warming. But that is a question separate from whether human activity is causing global warming.
I suggest that Happer et al enter the debate through valid research. As it stands now it seems that he is actually concerned with the economic implications of global warming rather than its effects on life as we know it. He may be honestly concerned with the consequences of human activity and how to best minimize the harm we cause, but he hurts his cause by writing an op-ed in the Wall Street Journal or First Things:
"First Things is published by The Institute on Religion and Public Life, an interreligious, nonpartisan research and education institute whose purpose is to advance a religiously informed public philosophy for the ordering of society."
I think that Happer et al have their own agenda, they should be honest enough to disclose it.
CO2 is increasing, but it is not as simple as you indicate. CO2 is already at a concentration that achieves over 90% absorption at it's relatively narrow band of wavelengths. Doubling the CO2 concentration only increases the greenhouse effect by a few percentage points.
Advocates of the "hair on fire" scenario have to resort to the argument that small increases in warming, due to CO2, cause an increase in water vapor, which in turn really does cause more infrared absorption, hence more increases hence "hair of fire". This completely ignores the opposite feedback, where water vapor causes more clouds to form, which reflect incoming infrared and cause cooling.
Whether the positive feedback or the negative feedback win out is a complex issue that cannot be addressed so naively as "CO2 is a greenhouse gas and causes warming". It is quite likely that the negative feedback works like a thermostat and keeps the temperature relatively stable.
Note that NONE of the computer models so often quoted has a mechanism for cloud formation, not one. This in itself is an astonishing fact, given the absolute certainty with which their proponents declare our future climate.
The article on the dissenting scientists misses a couple of important points. First, scientific truth is determined by evidence and logic, not by nose counts. But even considering numbers, the American Physical Society (of which I am a Life Member) has 50,000 members. Membership is not subject to any qualifying exam, nor (unlike religions or political parties) are dissenting members subject ot expulsion. I believe the other named societies are similar in this regard. Thus it's to be expected that there will be a few contrarians. incompetents, and members with conflicting affiliations within such organizations.
Second, the case for anthropogenic climate change is not based solely, nor even mainly, on weather records. It is predictable from well established physics and chemistry. We know the optical properties of CO2 and how it contributes to a "greenhouse effect." We also can plot the trend in CO2 concentration over a long historical period. This is from direct measurements in the last 50-100 years, and from ice core samples before that. (The two agree closely over the period where both are available.) The amount of extra CO2 corresponds to our consumption of fossil fuels since the industrial revolution began (correcting for that absorbed in known sinks). And isotopic analysis shows that the added CO2 is of fossil fuel origin.
As for the "natural" climate changes (Milankovich cycles) these take place over millenia, not decades, and according to the Milankovich theory we should be in a cooling phase now.
Permit a little analogy. If a kid is batting baseballs at the side of a house, one can predict from the scatter of trajectories and the kinetic energy of the ball that sooner or later he will break a window, even if he has not yet done so.
The legitimate debate in the scientific community is in the details of exactly how the effects of increased atmospheric heating will be manifested. (Which window will break and where will the pieces fall?)
We can think of the atmosphere as a heat engine (or an ensemble of engines), using temperature differences to perform work (wind, the water cycle, and other weather). Adding more heat the the "boiler" will make the engine work harder. This is likely to show up as intensified weather phenomena as well as a general temperature rise. If we wait until the catastrophe has already manifested itself to the satisfaction of the most die-hard deniers, it will be much to late to take any effective action.
So you are willing to follow with blind faith what your fav TV show says instead of finding out what the basis for these claims are just because there are only 16 of them? Doesn't really make you any different or more right than they are.
Mt. Pinatubo has been putting out greenhouse gasses over the last 20 years which total more than the total of all human emmission in recorded history. The recent eruptions in Iceland have emmitted enough CO2 to negate all "human" CO2 reductions over the last 4 years. The climate on this planet is changing and humans are extremely arrogant to think that their puny input into the system is driving the entire system. The planet climate changed before we were here, and it will keep changing after we are gone. The "climate change" program is nothing more than a way for left leaning politicals to get control of money and power.
I am not advocating a return to no pollution controls, but we need to use common sense.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
