Diatomaceous Earth (DE) — is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into a fine white to off-white powder. This is in fact made from diatoms and can be used to destroy mites and other parasites. It literally cuts them to shreds, it can be used externally or internally. But if you use it internally you must be food grade, the stuff they use in pools is not safet to take internally.

ABSTRACT:
"Carbon dioxide in the atmosphere [historically] is the product of oceanic respiration due to the well-known but under-appreciated solubility pump. Carbon dioxide rises out of warm ocean waters where it is added to the atmosphere. There it is mixed with residual and accidental CO2, and circulated, to be absorbed into the sink of the cold ocean waters. Next the thermohaline circulation carries the CO2-rich sea water deep into the ocean. A millennium later it appears at the surface in warm waters, saturated by lower pressure and higher temperature, to be exhausted back into the atmosphere. Throughout the past 420 millennia, comprising four interglacial periods, the Vostok record of atmospheric carbon dioxide concentration is imprinted with, and fully characterized by, the physics of the solubility of CO2 in water, along with the lag in the deep ocean circulation.
Notwithstanding that carbon dioxide is a greenhouse gas, atmospheric carbon dioxide has neither caused nor amplified global temperature increases. Increased carbon dioxide has been an effect of global warming, not a cause. Technically, carbon dioxide is a lagging proxy for ocean temperatures. When global temperature, and along with it, ocean temperature rises, the physics of solubility causes atmospheric CO2 to increase.
If increases in carbon dioxide, or any other greenhouse gas, could have in turn raised global temperatures, the positive feedback would have been catastrophic. While the conditions for such a catastrophe were present in the Vostok record from natural causes, the runaway event did not occur. Carbon dioxide does not accumulate in the atmosphere."

The graph above represents temperature and CO2 levels over the past 400,000 years. It is the same exact data Al Gore and the rest of the man-made global warmers refer to. The blue line is temps, the red, CO2 levels. The deep valleys represent 4 separate glaciation/ice-age periods. Look carefully at this historical relationship between temps and CO2 levels (the present is on the right hand side of the graph) and keep in mind that Gore claims this data is the 'proof' that CO2 has warmed the earth in the past. But does the data indeed show this? Nope. In fact, rising CO2 levels all throughout this 400,000-year period actually *followed* temperature increases -lagging behind by an average of 800 years! So it couldn't have been CO2 that got Earth out of these past glaciations. Yet Gore continually and dishonestly claims otherwise. Furthermore, the subsequent CO2 level increases due to dissolved CO2 being released from warming oceans, never did lead to additional warming, the so-called "run-away greenhouse effect" that Al Gore and his friends keep warning us about. In short, there is little if any evidence that CO2 had ever led to increased warming, at least not when the levels were within 10-15 times of what they are today. -ETL

"The above chart shows the range of global temperature through the last 500 million years. There is no statistical correlation between the level of carbon dioxide in the atmosphere through the last 500 million years and the temperature record in this interval. In fact, one of the highest levels of carbon dioxide concentration occurred during a major ice age that occurred about 450 million years ago [Myr]. Carbon dioxide concentrations at that time were about 15 times higher than at present." [also see 180 million years ago, same thing happened]:

So, greenhouse [effect] is all about carbon dioxide, right?
Wrong. The most important players on the greenhouse stage are water vapor and clouds [clouds of course aren't gas, but high level ones do act to trap heat from escaping, while low-lying cumulus clouds tend to reflect sunlight and thereby help cool the planet -etl]. Carbon dioxide has been increased to about 0.038% of the atmosphere (possibly from about 0.028% pre-Industrial Revolution) while water in its various forms ranges from 0% to 4% of the atmosphere and its properties vary by what form it is in and even at what altitude it is found in the atmosphere.
In simple terms the bulk of Earth's greenhouse effect is due to water vapor by virtue of its abundance. Water accounts for about 90% of the Earth's greenhouse effect -- perhaps 70% is due to water vapor and about 20% due to clouds (mostly water droplets), some estimates put water as high as 95% of Earth's total tropospheric greenhouse effect (e.g., Freidenreich and Ramaswamy, 'Solar Radiation Absorption by Carbon Dioxide, Overlap with Water, and a Parameterization for General Circulation Models,' Journal of Geophysical Research 98 (1993):7255-7264).
The remaining portion comes from carbon dioxide, nitrous oxide, methane, ozone and miscellaneous other 'minor greenhouse gases.' As an example of the relative importance of water it should be noted that changes in the relative humidity on the order of 1.3-4% are equivalent to the effect of doubling CO2.

Water Vapor Rules the Greenhouse System
Water vapor constitutes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many 'facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activities contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

It’s about time for the crazies to change back to us entering a new ice age. It’s a cycle you know!
What I don’t understand is weren’t we told that carbon dioxide released into the air causes global warming? Or was it some other organic thing?
Research by the University of Birmingham has provided evidence that a warm atmosphere rich in carbon dioxide was present in an ancient ice age. This could only have happened if the planet was nearly all covered in ice and snow.
Scientists from the University's School of Geography, Earth and Environmental Sciences, say that, whereas today, we associate more greenhouse gases with a warm world, in a very severe ice age, even plenty of greenhouse gas cannot stop the world being covered in reflective ice and snow.
This type of glaciation could occur again in the future if the Earth's atmosphere reflected too much solar radiation - this process could be triggered by a nuclear war creating a dusty mantle around the Earth. The same applies if we were not careful with a suggested technological fix for global warming and launched tiny particles (aerosols) of sulphate into the atmosphere. Such aerosols arise both from industrial pollution and from volcanic activity, and even in trace quantities are known to cause cooling. Dr Ian Fairchild, lead investigator, says, `We came up with an independent test of a theory that the Earth, like a baked Alaska pudding, was once hot on the outside, surrounding a cold, icy surface. It happened naturally in the past, but the wrong use of technology could make it happen again'
The breakthrough discovery was made by studying limestones that were deposited around 630 million years ago in salt lakes next to an ice sheet. The scientists measured the relative amounts of heavier and lighter forms of oxygen and sulphur and found anomalies that could only be accounted for by a very unusual composition of the atmosphere at the time. Appropriately, the place where the samples were collected is in Svalbard in the Arctic Ocean and is today covered in ice and snow, but 630 million years ago, nearly the entire planet would have been ice-bound.

Note from Admin: Looking at the actual paper, unless I read it wrong, it seems that the atmospheric CO2 concentration was around 12,500 to 80,000 ppmv compared to about 380 ppmv today.

The researchers assume that diatom populations are a cause, rather than an effect, of global temperatures and CO2 levels.
And in two days, this will be turned on it’s head too. I’d prefer more of these studies never saw the light of day in public. It just feeds the mentally ill global warming green goobers.
Bwahahahah ... looks like the Warmers have finally cottoned onto the cooling trend so are now making “discoveries” that will support a new theory that anthropomorphic CO2 causes Global Cooling. You’re gonna get that carbon tax one way or the other!
