What Causes an Ice Age to End?

The information below is taken from an article in the March 13th, 2020 Science and Environments University of Melbourne Newsroom. My father, who is a retired chemical engineer and has long been interested in and researched the concepts of “global warming” and “climate change,” shared this with me. Any edits I made are purely personal wording preferences.

Ice Age Team Drysdale

This team combined data from Italian stalagmites with information from ocean sediments drilled off the coast of Portugal. According to Linda Tegg, the new University of Melbourne research had revealed that ice ages over the last million years ended when the tilt angle of the Earth’s axis was approaching higher values. During these times, more prolonged and warmer summers melted the sizeable Northern Hemisphere ice sheets, propelling the Earth’s climate into a more heated “interglacial” state, like the one we’ve experienced over the last 11,000 years.

The study by Ph.D. candidate Petra Bajo and colleagues also showed that summer energy levels at the time these “ice-age terminations” were triggered controlled how long it took for the ice sheets to collapse, with higher energy levels producing fast collapse. Researchers are still trying to understand how often these periods happen and how soon we can expect another one. Since the mid-1800s, scientists have long suspected that changes in the geometry of earth’s orbit are responsible for the coming and going of ice ages. In essence, the uncertainty has been over which orbital property is most important. Petra Bajo’s paper, (Persistent influence of obliquity on ice age terminations since the Middle Pleistocene transition), published today in Science, moves closer to resolving some of the mystery of why ice ages end by establishing when they end.

The team combined data from Italian stalagmites with information from ocean sediments drilled off the coast of Portugal. “Colleagues from the University of Cambridge and Portugal’s Instituto Portugues do Mar e do Atmosfera complied detailed records of the North Atlantic’s response to ice-sheet collapse,” said Associate Professor Russell Drysdale, from the research team. “We could identify in the stalagmite growth layers the same changes that were being recorded in the ocean sediments. This allowed us to apply the age information from the stalagmite to the ocean sediment record, which cannot be dated for this period in time.” Using the latest techniques in radiometric dating, the international team determined the age of two terminations that occurred about 960,000 and 875000 years ago. The ages suggest that the initiation of both terminations is more consistent with increases in Earth’s tilt angle. These increases produce warmer summers over the regions where the Northern Hemisphere ice sheets are situated, causing melting. “Both terminations then progressed to completion at a time when Northern Hemisphere summer energy over the ice sheets approached peak values,” said Dr. Drysdale. “A comparison of these findings with previously published data from younger termination shows this patter has been a recurring feature of the last million years.”

The team plans to have a closer look nest at the Middle Pleistocene Transition when the average length of ice-age cycles suddenly doubled in duration.

Al Gore’s Inconvenient Truth

Al Gore is an extremely rich man!  He has been peddling a “Climate Change/Global Warming” scam that gullible left-wing Americans have bought into hook, line and sinker. Gore somehow even managed to win both a Nobel Peace Prize and an Academy Award for his nonsense from easily-led pseudo-intellectuals.  But, the real fact is that none of Gore’s dire predictions have actually come true!

Ten years ago Monday, Al Gore stated emphatically that we had only a decade left to save the planet from global warming.  According to his predictions, we should now be living in some kind of a giant frying pan! But surprise surprise, the Earth has been trucking along just fine.  Why do so many still listen to this man?  Generally they are the same people who still believe Barack Obama’s lies!  In short, they blindly drink the progressive Cool Aid!

I do remember how, at the  Sundance Film Festival in January 2006, during the premiere of his grand documentary, “An Inconvenient Truth”, Gore made his grand prediction. The former vice president stated, according to the AP reporter taking down his story, that “unless drastic measures to reduce greenhouse gases are taken within the next 10 years, the world will reach a point of no return.” In Gore’s own words, he claimed we were in “a true planetary emergency.”

Ten years later, he’s probably hoping that everyone has forgotten about his categorical statement.

The terrible truth for Al Gore is that there is no planetary emergency. Not one of the dire predictions he and the rest of the alarmist community made has come to pass. In fact, there is plenty of evidence that they have been getting rich from this hoax.

Investor Business Daily has a few more “inconvenient truths ” that Al Gore would rather not have the public hear (You will not find these truths on any of the left-wing, lap-dog media outlets; you know, the ones who felt a shiver run up their leg when Obama spoke and who now drool over Hillary Clinton):

  1. Earth hasn’t warmed in nearly 20 years. Yes, 2015 supposedly “smashed” the previous temperature record. But actually it was the third-warmest year on record and maybe “not even close to the hottest year on record,” says James Taylor of the Heartland Institute.
  2. Predictions that climate change (the re-branding of “global warming” when it turned out that predicted warming wasn’t happening) would cause catastrophic weather damage have simply not panned out. German insurance giant Munich Re says losses from natural disasters were lower in 2015 than in 2014 and lowest since 2009. The facts are sharply at odds with Gore’s 2012 claim that “dirty weather” caused by “dirty fossil fuel” has created “extreme weather” that “is happening all over the world with increasing frequency.”
  3. Despite all the self-congratulatory international conferences and pseudo-agreements, the world has done nothing to “fight global warming.” He cannot claim that his deadline has been extended because some governments have forced their citizens to cut carbon dioxide emissions. CO2 levels keep climbing and now exceed 401 parts per million in the atmosphere. It is simply not the dangerous greenhouse gas we’ve repeatedly been told it is.
  4. In the mid-to-late-2000’s, Gore repeatedly predicted that an ice-free Arctic Ocean was coming soon. But as usual, his fortune-telling was wrong. By 2014, Arctic ice had grown thicker and covered a greater area than it did when he made his prediction
  5. Gore’s movie, which somehow won an Oscar, was found by a British judge to contain nine errors. The judge said it could not be shown to students unless it included a notice pointing out the errors.

I suppose Al Gore is laughing all the way to the bank.

 

 

Obama: Job Creation Genius!

GLOBAL WARMING / CLIMATE CHANGE IS A HOAX

I must admit … Al Gore doesn’t give up (or know when to quit).  So, it now seems that if you do not allow yourself to succumb to the hysterical hype about global warming (aka climate change), you are now “racist;”  at least according to Al Gore!   It simply does not matter that the “global warming” scientists were caught red-handed falsifying facts to support their assertions, and that the real average global temperature has not risen!  It does not matter that Al Gore jets around in his PRIVATE JET spreading his “inconvenient” untruths while lecturing us all on decreasing our own carbon footprints; or that Al Gore admitted that his support for ethanol subsidies was a “mistake” and he was simply concerned with getting vote from corn growers in Tennessee and Iowa.  Let me get this straight … all that matters is that, if I don’t fall for his “scam” … then I am a racist.  I wonder what he would call his own dad … who voted against every civil rights bill that came across the table?

So, moving on …

Who in the heck uses T-Mobile?  AT&T has promised to bring 5,000 jobs back to the U.S. and create 96, 000 jobs modernizing their network infrastructure if they can buy T-Mobile.  It seems they would dearly like to have T-Mobile’s 4G network structure to help service AT&T customers.  But, good old Eric Holder (of “fast and furious” fame), is afraid of a AT&T monoply and that Verizon, Sprint, U.S. Cellular, etc., are not enough choices for the American public.  It is nice to see he has our best interests at heart! 

Who needs 101, 000 new private sector jobs anyway!  Obama is going save us all … he’s going to have the government employ us after next Wednesday.  So what if tax rates go sky-high to pay us all … at least we will all have government jobs!

The nerve of those republicans … scheduling their debate, way in advance, on the day Obama decreed he needed to have his jobs speech.  I am surprised, and a bit proud, that Boehner had the guts to call him on it. 

Speaking of jobs, I may be wrong, but I just bet Obama’s new jobs plan will want to borrow money from the treasury to create more government funded jobs that will naturally lead to increased taxes.  What the Obama administration doesn’t understand (or simply hates to admit) is the fact that small businesses make up about half of our nation’s annual Gross Domestic Product (GDP) and employ 60 percent of the American workforce. In addition to this, about 66% of all real new jobs in this country are created by American small businesses! 

That being said, I think that the “Anointed One” should create real private sector careers for citizens by doing things to help American small businesses create new jobs (what a thought). This would directly increase tax revenues because more Americans (who are not simply on the tax payer’s payroll) will be working.  This is much more effective than increasing taxes on those who already pay more than their fair share to form some new government job banks! 

Obama should then lower our energy costs by creating real energy jobs (and not chasing pipe dreams about wind powered cars, etc.). 

Lastly, he should drastically reduce the imports from foreign sources … particularly those sources who threaten the security of the U.S. and its allies.

How would this be done, you might ask?   Obama could start by:

  • Rolling back the quagmire of existing regulations that cripple small businesses.  Excessive regulation interferes with small business growth, and negatively impacts new job creation in the private sector.
  • Lift the oil drilling moratorium, and remove the miles of red tape that prevent more offshore oil drilling! Free up Section 1002 of the ANWR region of Alaska (less space than a square with 50-mile sides) for new exploration and drilling. 

By removing the red tape, and taking away the atmosphere of uncertainty and government created roadblocks; Obama could create  a lot of new jobs as American companies take advantage of new and sustainable opportunities to increase energy production, lower our dependence on foreign oil, and go along ways toward putting America back to work.

Anyway, just a few thoughts!
