|MEGASHARK GETS MORE MEGA, according to Science Alert and SciTechDaily 9 June 2021, and Palaeontologia Electronica DOI: 10.26879/1140. The size of the extinct giant fossil shark now named Otodus megalodon (used to be Carcharodon) has been re-estimated using the size of its teeth compared with teeth from the living Great White shark, then using the Great White’s body proportions as a guideline. Over the years a formula has been developed using the height of a fossil tooth to calculate the size of the shark it came from. Estimates based on this formula have ranged from 15 to 18 metres, but when Victor Perez of the Florida Museum of Natural History got school students to measure Megalodon teeth and use the formula they came up with wildly differing estimates. Part of the problem is that shark teeth vary in height according to where in the jaw they are located. So, it is necessary to know where in the jaw the tooth comes from. After studying a near complete set of megalodon teeth in the Florida Museum of Natural History, along with teeth and jaws of living sharks, palaeontologists have come up with a new formula based on the width of the teeth. The researchers now consider this a more accurate indicator as the width of the teeth is related to the width of the jaw, which is related to the overall size of the shark. Using the new formula the scientists have increased megalodon’s size to an estimated body length of 20 metres (65ft). There are still some limits to how accurate this new formula can be as there is no way to know whether Megalodon’s teeth had gaps between them or overlapped, as seen in some living sharks. Victor Perez of Florida Museum of Natural History, one of the researchers, commented: “Even though this potentially advances our understanding, we haven’t really settled the question of how big megalodon was. There’s still more that could be done, but that would probably require finding a complete skeleton at this point”. He still uses the shark teeth and the formula as a school lesson. He explained: “Since then, we’ve used the lesson to talk about the nature of science – the fact that we don’t know everything. There are still unanswered questions”.|

ED. COM. It is important for students to understand the nature of science, including its strengths and limitations. In this example the size of teeth can be accurately measured, but as the scientists admit they are not able to observe the precise arrangement of teeth in the megalodon jaw, so they must make assumptions based on living sharks. There is nothing wrong with this, but it is important to acknowledge what is actually observed vs what is assumed. Whatever the real size of Megalodon sharks, they were certainly a lot bigger than any shark observed in the present-day oceans. This should lead scientists to ask why the change? However, they will not find the answer just by studying present day sharks or fossil shark teeth. They need to know the real history of the world, i.e. that it started out very good, and therefore could support giant animals, but has since been degraded due to human sin and God’s judgement. Science will not reveal this. Only the written record of the Creator and Judge can reveal this, and scientists should be humble enough to admit it, and then use it to better understand the results of their study of the present-day world.
These climate scammers are serious in changing life as we know it.

Seems like every big policy gun wants to take a shot at fantasizing the decarbonization and electrification of the energy system. No doubt that is where the government policy analysis money is going. Sadly I am on the wrong side of the issue, money-wise, but it sure is fun flogging the fallacies in these so-called studies.
A few weeks ago we looked at the hilarious effort by the International Energy Agency. They were growing the global economy, and electrifying everything in sight, but had the need for juice going down in the process. Clearly impossible.
Two other recent reports are also worth laughing at. Which one is worse is hard to say, they are that bad. The titles begin to give the flavor of fantasy.
One is “The Future of Electric Power in the United States” by the collective National Academies of Science…

Critical Race Theory has been all the rage this year, literally. The media have adopted its language and assumptions, while companies, governments and even the U.S. government have inflicted the ideological poison on their personnel. And yes, it has crept into some schools. the mainstream media can’t stop talking about it. Conservatives have had enough of the left-wing indoctrination and many states have stepped up by creating legislation that prohibits schools from teaching curriculum that paints one race as superior to another. But now the backlash is sparking a backlash of its own, as progressives swear up and down they don’t see what the big deal is.
Valerie Strauss of The Washington Post published an article on June 11 titled “Teachers across the country protest laws restricting lessons on racism.” That’s The Post for you, professionals at creating deceptive headlines. Strauss covered the National Day…

Getting rid of Joe would be better than getting rid of fossil fuels but if Joe does get his foolish way Amish living will be a reality.

“We are going to get rid of fossil fuels” said President Biden.
For the first time since Harry Truman was president 70 years ago, America recently had more energy exports than imports. Now, under the Biden climate plan, America will be discouraging U.S. energy independence, starting with suspending Federal Oil and Gas Permits, encouraging the shuttering, and halting of further fracking efforts in America, and the cancellation of the Keystone XL pipeline.
Under Biden’s plan to rid American lifestyles and economies of fossil fuels, such a plan would ground the military, space program, and Air Force 1. It would also mothball the huge energy demands of airlines, cruise ships and merchant ships, as well as eliminate the medical industry, electronics industry, and the communications industry that are totally reliant on the products made from petroleum derivatives.
Getting-off-fossil fuels would reverse much of the progress made over…

eBay is offensive by being supposedly offended for others,
By Autumn Johnson ~
Retail giant eBay is censoring the resale of six Dr. Seuss books deemed “offensive” after the publisher announced the books will no longer be published.
Random House Books for Young Readers pulled “And to Think That I Saw It on Mulberry Street,” “If I Ran the Zoo,” “McElligot’s Pool,” “On Beyond Zebra!” “Scrambled Eggs Super!” and “The Cat’s Quizzer” because the “books portray people in ways that are hurtful and wrong.”
“eBay is currently sweeping our marketplace to remove these items,” a spokeswoman for the company toldThe Wall Street Journal.
“Dr. Seuss Enterprises has stopped publication of this book due to its negative portrayal of some ethnicities,” she added. “As a courtesy, we have ended your item and refunded your selling fees, and as long as you do not relist the item, there will be no negative impact to your account.”

When someone representing the government headed by the Fake President be sure to take it with a grain of salt and do some research on trustworthy conservative web sites such as the one where this article came from.

Dr. Anthony Fauci has had a bad month.
Hours past his fifteen minutes of fame, the avuncular Dr. Fauci has shown to be dishonest and self-serving regarding the coronavirus pandemic after 18 months of being the nation’s media darling. His cumulative contradictions and truth-shading, particularly the cause of the global Covid outbreak, are too obvious and disturbing to ignore.

Dr. Fauci’s craven cover-up of the origins of the Covid-19 pandemic are a continuation of a long tradition of government lying—both by politicians and life-tenured bureaucrats. Furthermore, his prevarication is a microcosm of the ongoing government-sanctioned misinformation and distortion about climate change as a way of justifying and implementing costly, ideological Green New Deal policies detrimental to Americans.
The recent release of Dr. Fauci’s email communication from early in 2020 at the outset of the pandemic revealed that he learned…

Can anything good come out of the NY Times?
By Clay Waters ~
New York Times reporter Ephrat Livni, who reports for the paper’s Dealbook business newsletter, dipped into hyper-partisan anti-Republican politicking in Monday’s print edition, “Taking Both Sides on Issues Like Voting Rights Can Cost Corporations – Scrutiny Over Donations That Conflict With Pledges.”
The online subhead: “Investors are on alert for companies that take one position and make donations that support another.” In other words, they pledge allegiance to “social justice” but stubbornly make some donations to Republicans.
The first portion of the 1,500-word behemoth cheered on shareholder activism for the environment and social movements, which is on the upswing on the left. The second half, rather amazingly, was devoted to more or less chiding corporations for donating any money to Republicans. Livni painted companies as hypocrites for signing on to “social justice” issues like “voting rights,” while – gasp! – continuing to donate some portion…
