is this a good hypothesis for a solar box cooker? | …
If you're serious about being able to provide for your family, be it during the the next power outage or a natural disaster – or even if you like the idea of cooking for free, make sure you add a solar cooker to your set-up today…
There is also evidence that life itself can contribute to mass extinctions. When the eventually , organisms that could not survive or thrive around oxygen (called ) . When anoxic conditions appeared, particularly when existed, the anaerobes could abound once again, and when thrived, usually arising from ocean sediments, they . Since the ocean floor had already become anoxic, the seafloor was already a dead zone, so little harm was done there. The hydrogen sulfide became lethal when it rose in the and killed off surface life and then wafted into the air and near shore. But the greatest harm to life may have been inflicted when hydrogen sulfide eventually , which could have been the final blow to an already stressed ecosphere. That may seem a fanciful scenario, but there is evidence for it. There is fossil evidence of during the Permian extinction, as well as photosynthesizing anaerobic bacteria ( and ), which could have only thrived in sulfide-rich anoxic surface waters. Peter Ward made this key evidence for his , and he has implicated hydrogen sulfide events in most major mass extinctions. An important aspect of Ward’s Medea hypothesis work is that about 1,000 PPM of carbon dioxide in the atmosphere, which might be reached in this century if we keep burning fossil fuels, may artificially induce Canfield Oceans and result in . Those are not wild-eyed doomsday speculations, but logical outcomes of current trends and , proposed by leading scientists. Hundreds of already exist on Earth, which are primarily manmade. Even if those events are “only” 10% likely to happen in the next century, that we are flirting with them at all should make us shudder, for a few reasons, one of which is the awesome damage that it would inflict on the biosphere, including humanity, and another is that it is entirely preventable with the use of technologies .

Solar Oven S-More
The Solar Oven is what is more widely known as a solar cooker and works on the principle of converting sunlight to heat energy and retaining the heat for cooking.

It’s clear that the current cycle is significantly weaker than the mean and far weaker than the cycles we saw throughout most of the warming 20th century. So far there have been a number of signs indicating that upcoming SC 25 will also be a weak one. Historically periods of weak solar activity are associated with cooler periods and altered weather patterns.
It has been CRAZY hot lately, so we took advantage of the scorching sun this past weekend and made a solar oven. The best part is we already had all the supplies on hand at home. The base of the project was a couple of personal size I saved in my craft stash for just this project. The boys loved making and decorating their own personal solar ovens but a big pizza box would work too.

After the mid-Permian extinction, marine life recovered and there were many radiations to fill empty niches, but coral reefs did not recover. Between the two big extinction events, extinction levels were highly elevated, which suggests that some of those aforementioned dynamics were still wreaking havoc, with possible . Critics of extinction hypotheses often say: “Correlation is not necessarily causation.” While there can be great merit to that position, it seems to be overused by various critics. When the guns are as smoking as volcanic events were, and they often “correlate” with mass extinctions, they are increasingly hard to deny as being at least immediately causative.

A has challenged The Expensive-Tissue Hypothesis, at least as far as robbing energy from the digestive system to fuel the brain. The study compared brain and intestinal size in mammals and found no strong correlation, but there was an inverse correlation between brain size and body fat. But since human fat does not impede our locomotion much, humans have combined both strategies for reducing the risk of starvation. Whales have bucked the trend, also because being fatter does not impede their locomotion and provides energy-conserving insulation. A human infant’s brain uses about 75% of its energy, and baby fat seems to be brain protection, so that it does not easily run out of fuel. However, the rapid evolutionary growth of an energy-demanding organ like the human brain seems unique or nearly so in the history of life on Earth, and comparative anatomy studies may have limited explanatory utility. There are great debates today on how fast the human brain grew, what coevolutionary constraints may have limited the brain’s development (, , ), and scientific investigations are in their early days.
But to do that, I need to come up with a hypothesis to test
Just as the aftermath of the appearance of complex life was uninteresting from a , as the amazingly diverse energy-generation strategies of archaea and bacteria were almost totally abandoned in favor of aerobic respiration, biological solutions to the problems that complex life presented were greatest during the Cambrian Explosion, and everything transpiring since then has been relatively insignificant. Animals would never see that level of innovation again. While investigating those eonic changes, many scientists have realized that the dynamics of those times might have been quite different from today’s, as once again may be of limited use for explaining what happened. Also, scientists generally use a rule-of-thumb called , or parsimony, which states that with all else being equal, simpler theories are preferred. , a seminal theorist regarding the scientific method, as they were easier to falsify. However, this issue presents many problems, and in recent times, theories of or speciation have invoked numerous interacting dynamics. Einstein noted that the more elegant and impressive the math used to support a theory, the less likely the theory depicted reality. Occam’s Razor has also become an unfortunate dogma in various circles, particularly , in which the of materialism and establishment science are defended, and often quite irrationally. Simplicity and complexity have been seesawing over the course of scientific history as fundamental principles. The recent trend toward multidisciplinary syntheses has been generally making hypotheses more complex and difficult to test, although and ever-increasing and more precise data makes the task more feasible than ever, at least situations in which are not interfering.

Recent environmental studies show that disturbed ecosystems can have cascading failures, as the removal of one part of a food chain can in , and entire ecosystems can go extinct. Cascades in today's world usually begin when the apex predator is removed (by humans, and called a ), but not always. Those cascading events can happen in aquatic and environments. Food chains are essentially energy chains , and the more complex they are, the more energy is required to sustain them. The leading hypothesis for why is also an energy-scarcity dynamic. Also, the most compelling findings that I have encountered regarding degenerative disease in humans shows that if individual cells no longer have their nutritional needs met by the organism, they stop acting out their role as specialized cells and “.” It may be difficult-to-impossible for scientists to reconstruct and test cascading failure hypotheses in ancient mass extinction events, but they may have played a major role in them, if not the dominant role.
