I believe the term is cherry picking data. What's amazing about all this is that it has not been proven that CO2 is actually causing much, if any significant warming. In fact, last year's data is showing that solar radiation is seeding clouds which may just be the culprit to all this. It would also explain the cyclical changes when you look at it from a proper point of view, say over thousands of years, not just 60.

To anyone who is familiar with the facts that the "paper" purports to address, I think it even goes past cherry-picking, and pretty far into the realm of propaganda and manipulation. As one of numerous examples, the author cites declining employment in mining as if that suggests mining is economically unimportant. He neglects to mention the major shift in coal production to the West, where production is almost entirely from highly efficient surface mines that have minimal overburden (i.e., no mountaintop removal issues) and conform with specific reclamation requirements. I somehow doubt that the author intends to promote western coal production - which addresses many of his gripes - but that's what can happen when too many sound bites get strung together without enough reality checks.

The paper also find a way to overlook several decades of effort to address environmental and mine safety issues associated with coal use. For example, it's kind of odd to hear gripes about acid rain when stringent SO2 requirements have already pushed the market to employ low-sulfur coal, scrubbers, etc. And I'm not sure why billions have been spent on baghouses, electrostatic precipitators, etc. if they don't materially reduce particulates.

It would be nice if the paper at least attempted to address the consequences of the reduced reliance on coal it seems to seek. Is it ok to have electricity prices go way up, even though this would be regressive, and have the most adverse effects on the low-income people the paper repeatedly cites? Is it ok to switch to other fossil fuels (oops, still big CO2 emitters) or shall we just shut down the part of the economy (close to half) that relies on coal-fired generation? Or maybe this guy is the last person on earth who believes that windmills and solar are ready to replace baseload coal plants. As the saying goes, "Any mule can kick down a barn; it takes a carpenter to build one."

David welcome to forum. Opposing opinions are welcome here but be prepared to defend then. If this is a "drive by" post just to a get a link to your site it will be removed.

I don't know what your motives are and I'm not specifically accusing you of anything but I get the feeling this will be the new tactic of environmentalist in the future, they will kill coal by promoting "clean coal". Increasingly activists no matter what the cause are using tactics similar to this where they achieve their goals through the backdoor, instead of outright banning something instead they are opting to try and make it very expensive. For example you don't ban guns, you ban the lead in bullets under the guise of environmentalism.

Kind of hard to get something wrong when you're making vague statements. For example let's take the bogeyman mercury that you mention here:

Mercury causes neurological damage, including lost IQ points, in unborn babies and young children exposed during the first few years of life. Mercury is taken up by fish and wildlife, and accumulates in the food chain. Coal-burning power plants are the largest point source category of mercury


Without context or a perspective this is useless information to the reader BUT I'll be glad to provide it for you so you can in turn provide it to your own readers. First and foremost the most important thing to understand about mercury emissions is it's a global issue, it's not a confined local issue. According to the EPA very little of the mercury emitted form US coal plants is deposited within the US and in the global context US coal fired power plants are responsible for only 1% of the global pool. Even If we were to completely eliminate all emissions it's going to have little effect on the deposition rates here in the US or globally. I'd argue that the stricter emissions standards here could in fact produce more emissions. Energy costs are not the only consideration a company makes but it's certainly one of the bigger considerations, as energy costs rise here it's just that much more incentive to move manufacturing overseas.


Mercury Emissions: A Global Problem

* Mercury emitted from coal-fired power plants comes from mercury in coal, which is released when the coal is burned. While coal-fired power plants are the largest remaining source of human-generated mercury emissions in the United States, they contribute very little to the global mercury pool. Recent estimates of annual total global mercury emissions from all sources -- both natural and human-generated -- range from roughly 4,400 to 7,500 tons per year. Human-caused U.S. mercury emissions are estimated to account for roughly 3 percent of the global total, and U.S. coal-fired power plants are estimated to account for only about 1 percent.

* EPA has conducted extensive analyses on mercury emissions from coal-fired power plants and subsequent regional patterns of deposition to U.S. waters. Those analyses conclude that regional transport of mercury emission from coal-fired power plants in the U.S. is responsible for very little of the mercury in U.S. waters. That small contribution will be significantly reduced after EPA’s Clean Air Interstate Rule and Clean Air Mercury Rule are implemented.

o U.S. coal-fired power plants emit mercury in three different forms: oxidized mercury (likely to deposit within the U.S.); elemental mercury, which travels hundreds and thousands of miles before depositing to land and water; and mercury that is in particulate form.

o Because mercury can be transported thousands of miles in the atmosphere, and because many types of fish are caught and sold globally, effective exposure reduction will require reductions in global emissions.



Despite this analysis the EPA has recently instituted new regualtions to reduce mercury emissions. The primary issue with mercury is neurological which you have mentioned, so what do we as a nation get in return for these new regulations? Not a whole lot, according to EPA estimates the increase in IQ is immeasurable using any testing standard. This is from the EPA's own cost/benefit analysis for these new regulations.

Regulatory Impact Analysis for the Final Mercury and Air Toxics Standards


The average effect on individual avoided IQ loss in 2016 is 0.00209 IQ points, with total nationwide benefits estimated between $0.5 and $6.1 million.


Astounding isn't it? What do you think the error bars on those estimates look like? We're going to spend 10's if not hundreds of billions to increase the average IQ in the US an entire 2/1000 of one point if the EPA's estimate was to be taken at face value. The reason for such low numbers goes back to the fact this is a global issue and US coal fire plants account for so little of global emissions. Total reductions in the deposition of mercury inside the US is estimated from 1% to 10%.
Economic Valuation of Human Health Benefits of Controlling Mercury Emissions from U.S. Coal-Fired Power Plants

Changes in mercury deposition rates associated with reductions in power plant
mercury emissions are based on regional deposition modeling results from the EPA's
analysis of the Clear Skies Initiative. In its analysis, the EPA simulated current mercury
deposition rates and the changes in these rates that would result if power plants
reduced their mercury emissions from the current rate of 49 tons per year to either 26 or
15 tons per year. We used these predictions to estimate changes in deposition rates for
the freshwater regions, the Atlantic Coastal Region, and the Gulf of Mexico. Estimated
decreases range from approximately 1% to 10%.
The change in deposition rates to the
All Other Waters region is assumed to be proportional to the change in total global
emissions that would result from U.S. power plant emissions reductions, which is less
than 1%.


Let's take another one:

Acid gases cause lung damage and contribute to asthma, bronchitis and other chronic respiratory disease, especially in children and the elderly. In humans, acid gases irritate the skin, eyes, nose, throat, and breathing passages. In the environment, acid rain from NOX and SO2 damages crops and forests. Coal-burning power plants are the largest point source category of hydrochloric acid in the US


The old lets blame coal for asthma. Despite the fact the 6 most common air pollutants have decreased as an aggregate by 67% since 1980 and asthma diagnosis have increased substantially in that time the EPA still tries to lay the blame on coal? The specific reductions for NOX is 52% and SO2 is 69%.


EPA Air Quality Trends

I'm no doctor or scientist but I think perhaps the blame lays elsewhere? I would suggest it's a combination of a few factors. Firstly in this time span houses have become much more efficient but they trap indoor air pollution, the use of forced air for both heat and AC has increased dramatically and kids simply spend more time inside. Sound like a reasonable explanation?

Somewhat unrelated but since this is forum for burning coal it's pertinent, there is medical study that found people in homes using coal or wood for heating had less asthma cases.

Particles cause premature death and a wide range of lung and heart diseases. Particle pollution from power plants is estimated to kill approximately 13,000 people a year.


As far as this goes do you know how they arrive at these figure? Obviously there is no one that has "died from coal particulates" on their death certificate. They use what is called a linear dose assessment which makes the assumption that every particle is equally as dangerous, the amount of exposure is not a factor. They take a known value, for example suppose we have a 20 foot cliff that ten people have fallen off and five of them die. From this it is determined that for every 200 feet a population is to fall 5 will die. If twenty people fall off a 10 foot cliff 5 of them die, if forty people fall off a 5 foot cliff 5 people still die. If 1 million people fall off a crack in the sidewalk 5 still die which is absurd, this last example with a million people would be most comparable to saying 13,000 people die from particulate emissions.

While there *may* be a small potential for health effects nobody dies from particulate emissions. Trying to accurately gauge such health risks is all but impossible and when you try and quantify the risks for individuals you get infinitesimally small numbers like 2/1000 of IQ point. There is only one purpose for such estimates which is to give the media, environmentalist and others ammunition in their crusade to kill coal regardless of the fact they are bogus.

I love it when they try to use mining safety as a reason against coal. Green energy jobs haven't been around long enough to make the lists but it's easy to figure out that they would rank pretty high on the dangerous spectrum. Most solar panels go on roofs; roofers are usually one of the top 3 dangerous jobs. Huge windmills can't be the safest job out there, especially the ones in the middle of the North Atlantic. I don't think anyone has done this type of study but I'm positive the btu's per coal miner is exponentially higher than the btu's per solar panel/wind mill erector.

Everything was proven when they put in the Reg.s for strip mines decades ago, before that the owners just took & ran. Now it seems OK to go right back to the same old ways & somehow it will be different this time around. Just like before the little guy will end up with the bill but this time around it will be a lot larger if at all obtainable & many here will be gladly paying up without a gripe.

It's dangerous job but you're more likely to die working as sales clerk, trucking. logging.... The reason it makes news is becsue usually many die at once. The hundreds of truckers killed in accidents every year don't make the national news.

tsb, Take a little tour down to W.V. & a few other states where mountaintop removal is going on & then tell me we aren't going backwards. Having worked for a major polluter for most of my life I know first hand what they will do if allowed. Toward the end of last year I got the chance to fly over some of those active & inactive mining areas so I have a pretty good idea of what they look like & from some pictures what they did look like IMHO we went back & then some.
