william5331 at 05:23 AM on 27 March 20193 clean energy myths that can lead to a productive climate conversation
There is another aspect to the wind farm argument. Let's assume, for the sake of the argument, that a wind turbine only returns an amount of energy equal to what is used in it's construction before it has to be replaced. (not true but bear with me). The country where you are building these turbines creates all it's energy from fossil fuel. You build wind turbines sufficient to generage 10% of the nations electricity, replacing that amount of coal. Now the next tranch of wind turbines are build with 90% fossil fuel energy and 10% renewable energy. you see where this is going. We eventually get to a point where the wind turbines are being made entirly with renewable energy. Since, in fact, wind turbines return far more energy that is needed in their manufacture, the argument is far stronger.

SIr Charles,
In your comparison of wind and nuclear you did not consider the opportunity cost of nuclear versus wind. Jacobson 2009 (cited over 1200 times) calculates opportunity cost of various plants. Because of the very long lead times to build a nuclear plant much more fossil power is generated during the building of the plant compared to a renewable plant.
For example, let us imagine you want to build a 1 megawatt (delivered power) wind energy plant. It takes about 2 years to get approval and 2 years to build. Then you get your energy.
If I want to builld a nuclear plant it takes 5 years to get approval and about 10 years to build. Your wind plant has been generating power 11 years before my plant is comissioned. That 11 years of missed power has to be supplied by fossil fuel plants until the nuclear plant is finished.
This makes nuclear a very high emitter of CO2 compared to renewable plants which are much faster to build (and produce partial power when partly completed). Many analysis of nuclear leave out the opportunity cost CO2.

Sir Charles:
We agree. Nuclear requires at least a gigawatt of spinning reserve at all times in case of an incident as you describe. These incidents happen about once every two years in the USA. For renewables the biggest incident is losing a transmission line which can be countered with an adequate grid.

This result also intuitively makes sense if you look at the average annual maximum extent of Arctic Sea Ice. The Acrtic Sea Ice advances far down into the Labrador Sea, while a large area of open water remains North of Norway.

One Planet Only Forever at 01:55 AM on 27 March 2019Major study uncovers ‘sea change’ in world’s understanding of Atlantic conveyor belt
The following quote in the OP appears to double describe what is being meaured (the part I show in italics).
“It consists of a whole load of moorings, which are ways in which we string instruments between the seafloor and the sea surface in the deep ocean. So there’s an anchor at the bottom and along that wire we string instruments that can measure various things like the speed of the water, the velocity of the water, temperature and the salinity.”
Is the direction of flow being measured? Is that what one of the two 'speed/velocity' points should have been?

william,
I agree that elected representatives 'dedicated to appealing to rich supporters/promoters' can be problem. And limiting the influence of rich people is part of the solution.
But wealth influencing an election is only a problem if those rich supporters/promoters are the type of people who have developed a willingness to pursue perceptions of status in ways that are harmful to Others.
A related problem is the pressure on elected representatives who would rather not appeal to those type of supporters/promoters. The power of misleading marketing can make elected representatives vote against their better judgment on some issues. They will do that because they believe, likely correctly, that they the need to vote that harmful way on that issue to continue to win the power to vote the helpful way they want to on other issues.
The real problem is not money influencing politics. The real problem is the ability of misleading political marketing to be done without penalty.
Setting up rules to limit who spends how much money does not address the real problem. Setting up laws that can be enforced to remove a candidate who benefited form misleading marketing is also not an easy answer. Offensive opponents can simply create misleading marketing that would then be the basis for removal of the non-offending candidate.
The real problem is the socioeconomic-political system that has developed. Systems that encourage people to 'develop a willingness to pursue perceptions of status in ways that are harmful to Others' will also develop resistance to correction. The fundamentals of the system causing the harmful developments is what needs to be corrected. Without the Errors in the System being corrected (more fundamental than money in politics), any attempted 'fixes' will struggle to be popular and profitable enough to be successful.

@9.michael sweet
French nuclear has an overall capacity factor of 75%. Not much more than offshore wind. Whereby, when a nuke has in incident you're loosing a gigawatt or more in just a few seconds. Meanwhile, wind is predictable for many hours in advance and the grid can easily be adjusted accordingly.

One Planet Only Forever at 15:17 PM on 26 March 20193 clean energy myths that can lead to a productive climate conversation
An Implicit but never stated "Incorrect Myth" regarding renewable energy is: "Future generations of humanity can continue to benefit from non-renewable energy, particularly the burning of fossil fuels."
The reality is that future generations cannot continue to benefit from non-renewable energy sources'. And there is no way to claim they can. The benefit is obtained by their predecessors. The future generations get no sustainable benefit from the activity being done by their predecessors. All that the future generations get are harmful impacts, many of which cannot be undone no matter how brilliant people in the future are, and reduced amounts of non-renewable resources.

nigelj at 12:27 PM on 26 March 20193 clean energy myths that can lead to a productive climate conversation
Some interesting ideas on electricity efficiency scattered through this list from the Project Drawdown people.
There is a lot of potential, but the average family still faces obvious constraints. I think it's unlikely people would drastically reduce electricity use so that they go cold, or go without air conditioning. I would suggest most people apart from the rich already try to keep electricity bills as low as possible.
Big gains can be made with adding double or triple glazing, extra wall insulation, heat pumps etc: but they cost money. Tax incentives might help.
I think the bottom line is it's hard to avoid the need for a big build out of renewable electricity generation as fast as possible. And it is possible technically and economcially, its a case of whether there is the will do do it.
-
scaddenp at 11:41 AM on 26 March 20193 clean energy myths that can lead to a productive climate conversation
Well 2 biggies for energy efficiency are electrification of transport (60% of energy going to wheels cf 20% for petroleum-based) (ref), and solar PV for electricity generation instead of coal and gas. While replacement will take a while, that means all the more urgency for serious effort now.

Hi Electric @669,
Yes a agree it's a pointless point but that denier keep trying to use it to prove CO2 is good for the planet which of course it's true, but only when the balance is not offset.
Most of this deniers tactics are what both you and David pointed out...they are sprinkled with some facts but the conclusion he draws from these facts is misleading which is what I try to point out to the bystanders reading his chest beating comments.

@668 : let it slide, TVC15 .
In the end, it's rather futile to debate the origin of metabolic carbon ~ since the terrestrial carbon cycle moves C around continuously [not counting fossil carbon]. As David Kirtley says, its ultimate origin is from some distant stellar source, pre-dating our own sun.
If anything, one might say that lifeform C in evolutionary terms originated from lipids and/or carbonates/bicarbonates in the primordial ocean. And there can be other arguments too . . . all getting a bit Angels on a pinhead. But your denier friend wasn't entirely wrong in his point about carbon ~ though it certainly was a pointless point he made.
I hope you've had time to enjoy a few of the Potholer54 videos on climate science. He has five [FIVE] on the asinine antics of the eloquent Lord Monckton ~ quite amusing to see the "error-prone Viscount" [unquote] shoot himself in the foot repeatedly.

Renewables are not going to replace fossil fuels any time soon. See below. The two changes we need to make to reach a sustainable future are to reduce the amount of energy we use and to use what we do generate much more efficiently (2/3rds of energy generation is lost as heat without doing any useful work!)

David@667,
I don't follow how what I posted does not clarify?
In fact when I challenged the denier with what I posted here he stopped posting over and over the same manta that CO2 is a basic building block of life. No CO2 is not a basic building block of life.
Then he came back with the Carbon in carbon based life originated from CO2.
He stopped spreading his misinformation after I debunked both of his inaccurate statements.
-
David Kirtley at 10:02 AM on 26 March 2019Climate's changed before
Sorry, TVC15, that doesn't clarify it. Yes, ultimately all carbon on earth comes from stars. We both agree about this. But the origins of life are not relevant here. I don't know what chemical pathways led to the origin of life, or if this involved CO2 or not. But today, right now, my everyday existance depends on atmospheric CO2.
The question is: where did the carbon in my body come from? If you follow the trail it is clear that the carbon in my body came from the food I ate: plants and animals. Those animals get that carbon from the plants they eat. And all plants get that carbon from the CO2 floating in the air.
None of this is inaccurate or controversial. It's Biology 101. Yes, you can follow the trail back to the ultimate origin of the element carbon inside the nuclear furnaces of stars. But why? The question is about life on Earth now.
Your denier has stated some true facts about the carbon cycle and then tried to use this to draw an invalid conclusion about whether CO2 can be classified as a pollutant. Now you, by focusing on the ultimate origin of carbon in stars and now bringing in info about the origins of life, have totally missed the real misinformation that he is trying to push.

Hi David @ 663,
This denier loves to say that the Carbon in our bodies *orginated* from CO2. This is not accurate.
The building blocks of life come from elements and elements orginated from stars.
Origin of Life’s Building Blocks in Carbon- and Nitrogen-Rich Surface Hydrothermal Vents
As I pointed out to this denier show me where CO2 is mentioned in this paper as being how carbon based life originated.
Origin of organic compounds on the primitive earth and in meteorites.I hope this helps to clarify.
-
David Kirtley at 07:17 AM on 26 March 2019Climate's changed before
TVC15 @663. I'm not following you. The elements originate in stars. The Earth was made of "star stuff." But I usually eat plants and animals, not rocks.
Plants take in CO2 from the atmosphere, photosyntesize, and build the stuff of plant tissue from that. Animals, including me, eat plants. Other animals, including me, eat animals which ate plants. We transform the plant/animal material into the stuff of our animal bodies. All that carbon origianlly came from the atmosphere.

Actaully I agree that changes in Arctic are interesting - we have had a sequence of warm winters and cloudy summers which are certainly of scientific interest in understanding weather. Likewise the effects of flip in NAO on weather patterns are very important for future weather prediction. However, thinking that these represent a climatic change is wishful thinking.

I told the denier this:
I find it amusing as well that you don't understand that the Carbon found in carbon based life is not from CO2. You should know that Carbon is very abundant on Earth and of the 92 naturally occurring elements (except for elements 43 and 61), only six of these elements make up some 99% of all living tissue. Ever heard of CHNOPS?
You might want to look up where elements originate.

Joe Z @2
"Large scale solar "farms" are often built over fields and forests- resulting in a loss of carbon sequestration and oxygen production and widlife habitat as shown in a video I did of one built close to my home-"
In America forests cover 33% of the land, which is 300 millon hectares of land. Its been calculated that if solar power provided all of Americas electricity it would cover approximately 2.5 million hectares of land so less than 1% of the land covered by forests. In reality America will use a mix of energy sources, so it will be something less than 0.25%.
I don't see that this small number is a significant or unacceptable loss of forests (or fields). We waste enormous quantities of food and timber each year. Reduce that by just a faction and it would compensate for land used for solar panels.

Nuclear and coal, and other "baseload" power sources have the opposite problem associated with renewables. They generate too much power at night so much of their capacity is wasted. Many people are not aware that most of the existing pumped hydro was built in the 60's and 70's as a method to store excess nuclear power at night for use during peak power during the day.
In France they shut down many of their nuclear plants on the weekend. Since the cost of nuclear facilities is so high, it is very expensive to shut down facilities for any reason.
When people ask about storage of renewable energy, it is interesting to ask about storage of excess baseload for use during peak power.

Just because you cherry-pick different dates to suit your purpose does not invalidate the statement:
"Data from NASA's GRACE satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower) have been losing mass since 2002. Both ice sheets have seen an acceleration of ice mass loss since 2009."
-
Molsen at 02:19 AM on 26 March 2019Greenland is gaining ice
According to the NASA (GRACE) data, the average loss from 2009 to 2013 was 399 gigatonnes per year. From 2013 to 2017, the average loss per year was 190 gigatonnes per year.
The statement that there has been an acceleration of ice mass loss since 2009 is factually wrong. At the very least, there has been an interesting pause in that "acceleration" since 2013. It's kind of like minimum summer sea ice extent in the Arctic: it has kind of been going sideways (i.e., not declining) for the last 12 years or so. Again, interesting....

You can look at the math that others have done it them:
"building and running new renewable energy is now cheaper than just running existing coal and nuclear plants"
And
"the full-lifecycle costs of building and operating renewables-based projects have dropped below the operating costs alone of conventional generation technologies such as coal or nuclear"

JoeZ at 00:29 AM on 26 March 20193 clean energy myths that can lead to a productive climate conversation
Tom, here in Massachusetts, such lifecycle for solar and wind are apparently NOT considered. They probably are among some scientists- but not among the politicians who determine policy and write laws. Currently, solar is popular in this state but the total production of solar is still very small. State law will requre far more and much of this will be on solar "farms"- which as I note, have drawbacks that are NOT looked at here. I'm not aware that anyone has actually counted the loss of carbon sequestration and oxygen production of a solar farm. The one near my 'hood was once a gravel pit but half of it had grown back to forest. So, that forest had to be destroyed. Nobody counted the loss of carbon sequestration and they also didn't count the fact that all of that wood went a biomass plant. The irony is that forestry critics in Mass. hate biomass- yet their beloved solar farm sent a great deal of wood to a biomass plant.
Now, the fact is that forestry is renewable. But here in Mass. we've had and still have a war over biomass. Many critics really do want to lock up all the forests and they really don't respond to questions as to the consequences of that.
Let's face it- all these issues are extremely complicated. Nobody has all the answers. There is no magic bullet- though long term I think it will be fusion. Since this web site is about skepticism- it might be nice if those who really do think it's all about fossil fuels to just try to be a bit skeptical- the way lawyers are taught to argue either side of the case. It might be worth the mental exercise.

9. Did you know that ALL of the carbon atoms in your body (as you are an organic organism) was once CO2? That is the carbon cycle; CO2 is as important to life on earth as water and oxygen
This is true, but so what. He's using just enough sciencey stuff to show that he can be "trusted" and then he draws illogical conclusions. Here he concludes that since CO2 is such an important building block of all life on earth it can't possibly be a "pollutant". Water, as he points out, is also a fundamental necessity, but you can still drown in the stuff. Too much of it all at once can destroy your house. The dose makes the poison.Anyway, be careful of just labeling his statements as "False!" Instead, be mindful of where his misdirection lies and point out, for the sake of the lurkers in the conversation, his flawed logic.

"A particularly elegant solution is pumped hydro, which uses surplus wind energy to pump water uphill." Sounds good, but here in Massachusetts- there is a big battle going on over the only such pumped hydro facility. Those critics are against all fossil fuels, against pumped storage, want to stop all tree cutting, against nuclear- and though many are in favor of solar and wind- they will never respond to my critiques of large scale wind and solar "farms" (note my previous post here), they will not respond to my questions as to how will we get by without wood as a low carbon footprint raw material if they lock up all the forests- and amazingly, many who are even all of the above are even against wind and solar! In the local paper this morning I see an editorial by a guy who says we should all get off the grid, use outhouses, and pump water by hand. It doesn't seem to me that we can solve problems by being against every option. I recall that President Obama suggested we need to use all forms of energy, wisely of course.

Large scale solar "farms" are often built over fields and forests- resulting in a loss of carbon sequestration and oxygen production and widlife habitat as shown in a video I did of one built close to my home- which doesn't mean I'm a NIMBY because I don't like them anywhere: https://vimeo.com/260469370. Also not counted is the cost to dispose of the at least somewhat toxic panels when the "farm" is terminated. Also not counted is the carbon emissions to ship the panels across the planet from China (how about toxins emitted to make the panels in China), then to truck them to the site from some port- and huge carbon emissions needed to build them- at least this one as you'll notice all the huge machines that were needed. So, maybe there still a good thing- but not counting such externalities is NOT smart.

Cedders at 19:36 PM on 25 March 2019Models are unreliable
It's been suggested that 'models are unreliable' is a particularly pernicious myth. The models have been useful, and are getting even better, but some make the false claim that models have deviated demonstrably from reality.
Those who are misinformed or content to be misinformed often make up unsourced past 'predictions', perhaps because they are reacting against journalists' sometimes sensationalist ways of describing individual studies. Eg in the last few days in response to a climate article: "By 2016, New York will be under a foot of flood-water because of all the melting ice caps, melting glaciers and so on", which is clearly not a direct quotation despite being in quotation marks and impossible to trace as a statement.
If they're schooled in climate confusion, they might refer to Peter Wadhams's projections of sea ice, or the chat with James Hansen; on social media you often find images of local press cuttings, taken out of context and with pink highlighter taken from Tony Heller's blogs. (There's also the argument, which that because models can't reliably predict short-term weather patterns, how can predictions be made for decades in advance, how the range of weather is affected by changes in the Earth's energy balance.)
This article includes links to CarbonBrief's series on modelling, but I don't see a link to Zeke Haufather's comparison of historical models against later trends:
LINK(The late Wally Broecker's simple 1975 model was nearly spot on. Then there's the 1979 Charney Report.)
Also, I found this a useful resource:
LINKIt's not just that 'Models successfully reproduce temperatures', but also patterns of warming.

Trevor_S,
There is often a pattern to major social changes. When the change will be a correction based on improving awareness and understanding that contradicts already developed popular and profitable attitudes and activities a significant resistance to correction can develop. The result is the regional perception of continued success, continued increased perceptions of status. But the required correction just becomes more significant and urgent as the improving awareness and understanding inevitably gains power.
Regions with leadership that is significantly resisting the corrections of their understandably harmful and ultimately unsustainable pursuits are setting themselves up for more significant disappointment. It may appear as though they will never lose. But the harder they fight to resist being corrected, the bigger and more rapid the correction occurs.
I live in Alberta, Canada. The resistance to correction is massive here. And the anger of disappointment regarding correction of the over-development in the wrong direction that has occurred through the past 30 years is very apparent. To an outside observer, someone not immersed in the desire to benefit from the global burning of fossil fuels, so is the inevitable reality that the correction will happen and be more dramatic the more that people in Alberta temporarily regionally win their fight against it happening.
The trend of improving awareness and understanding regarding climate science and the required corrections of developed popular and profitable activities is very obvious. The speed and magnitude of the correction in any region is a function of how aggressively the winners in the region try to resist the correction. The longer it is delayed the more disappointing the correction becomes for those resisting the correction.

Secondly, given what I know of how science is funded in USA (at least the NSF), then I find it pretty difficult to see how these selfish reasons work in that framework. As for selfish reasons of government, that is getting into conspiracy theory territory, especially given the antipathy to AGW of current and former governments.
Real skepticism about climate science has to provide evidence. That is what skepticism is about and that is what this site is about. Real skepticism backed by real data is very welcome.

Why does the media give these people oxygen? Caleb Rossiter knows nothing about climate change. His qualifications are:
M.A., mathematics, American University (2004). [1]
Ph.D., policy analysis, Cornell University (1983). [1]
M.S., Education, Cortland State (N.Y.) University (1976). [1]
B.S., Human Development and Family Studies, Cornell University (1973).[1]One or two quotes:
"He also proclaimed that carbon-based fuels improve life expectancy in developing countries by increasing the amount of CO2 in the atmosphere, acting as a “fertilizer,” and ensuring electricity generation, concluding:“I come not to bury your carbon but to praise it.” [8]
Woeful, just woeful. (In response to Rossiter's op-ed, the Institute for Policy Studies terminated his Associate Fellowship, telling him in an email..)
An article for The College Fix recounted the story of how Rossiter once flunked a student who had submitted a paper affirming the role of human activity in climate change:
“I had to raise her grade because she certainly had cited the evidence they had given, but I just couldn’t give her much of a grade because she should have been able to see – as most people should be able to see – that the computer models were just guessing and sort of notional, and just kind of playing around to get a good fit, but didn’t have much scientific basis.” [10]"
I don't usually use the term, but this is pure ignorance.
