Global warming is certainly a “hot” topic at the moment ( 🙂 silly pun….sorry…)
We have the scientists on one side, laying out the facts as we understand them, presenting the research, and calling for action before the harm we’ve already done to our environment becomes irreversible. We are all familiar with those arguments – we see them in the news, in the scientific publications and on Discovery Channel every day.
On the other side, we have the deniers, flatly refusing to accept that the climate is changing, or that human activity is causing these (probably permanent) changes. Some even claim that their god would never allow the climate to change, because their holy book tells them so:
Genesis 8:22, ‘while the earth remaineth seed time and harvest, and cold and heat, and summer and winter, and day and night shall not cease,’
(Nobody is saying that climate change will result in the cessation of cold, heat, summer, winter, seed time or harvests anyway, so I don’t see the relevance).
Climate CHANGE is not climate ABOLITION – perhaps these people need to get their heads out their backsides and read something OTHER than the bible?
They were wrong about THIS too!
I was very amused to read this article which claims that global warming will cause the entire earth to EXPLODE!
“Bioresonant” claims that there is a nuclear reactor at the core of the earth, and it requires cooling (as all such devices do). Unfortunately, the anthropogenic warming of the atmosphere is preventing the cooling of the reactor – and pretty soon we will have a runaway nuclear explosion, which will destroy the entire planet!
Doctor Tom Chalko, MSc PhD, published his theory in the NU Journal of Discovery in April 2001. (Chalko appears to be the only contributor to this “Journal.”) He maintains that life on Earth is only possible because the core is efficiently cooled; there is a balance between the interior heat, the heat received from the Sun, and the heat radiated away into space. If the atmosphere becomes too polluted, too much heat from the Sun will be trapped at the surface, the interior cannot cool down – and the result?
The most serious consequence of such a ”meltdown” could be centrifugal segregation of unstable isotopes in the molten part of the spinning planetary core. Such segregation can ”enrich” the nuclear fuel in the core to the point of creating conditions for a chain reaction and a gigantic atomic explosion.
He claims that the polar icecaps are melting from underneath (increased volcanic activity due to the rising temperature of the core) not because the air around them, and the water they’re floating in, is getting warmer. (That’s why an ice block melts, floating in a glass of white wine, on a warm day – it’s the nuclear fission reaction at the CORE!)
Do you doubt that an entire planet can explode? No, really it can! Greek mythology confirms it! The planet Phaeton disappeared “in a flash” – that must have been a runaway nuclear fission explosion at its core, caused by alien-induced atmospheric warming, right? What else could it have been?
(According to Wikipedia, in Greek mythology, the name Phaeton was the personification of the planet Jupiter. I know from my own personal experience that Jupiter can be incredibly bright sometimes – perhaps it was hit by a large comet and became temporarily even brighter? Jupiter tends to attract large objects entering the Solar System because of its mass…. the comet Schumacher Levy strike is a perfect example.)
Dr Chalko goes on to claim that earthquakes are becoming more frequent and more violent as a result of the increasing heat of the nuclear reactor within our planet. He also claims that the core is spinning 4% faster than the earth spins on its own axis. And, the centrifugal force of this spinning is causing the radioactive isotopes to accumulate in the centre and they will soon reach a critical mass and we will have a NUCLEAR MELTDOWN! There will be nowhere for that heat to go —- volcanoes will explode, the atmosphere will be darkened, we are all going to DIE!!!
Anyone with half a brain can see right through this argument, but apparently not everyone HAS half a brain…. When the theory first popped up, some people actually took it seriously!
So, let’s look at the facts:
- The earth has a solid ( mostly iron) core, surrounded by a molten mantle and a thin, solid crust.
- The solid core is hot – hotter than the surface of the Sun – but that is only about 6 000 degrees C. (The Sun’s real heat is not at the surface, but in the centre (15 million C) and the corona surrounding it which reaches 1 to 3 million C)
- The Earth’s inner core is rotating slightly faster than the outer core, but it would take more than 1000 years to “lap” the planet (not 20 – 25 days, as it would if it were rotating 4% faster than the rest of the planet!)
- Most of the earth’s heat is stored in the mantle, which is still cooling from when the planet first formed 4.5 billion years ago or so.
- The inner core is cooling down, and this is causing it to expand by about 1cm every 1000 years. This expansion releases heat which is also warming the mantle.
- Most (about 90%) of the heat of the earth’s interior is the result of the radioactive decay of isotopes such as Potassium 40, Plutonium 235 and 238, and Thorium 232, contained within the mantle and the crust.
- In several billion years the earth will have cooled completely and will be cold like the Moon – but the Sun will probably have expanded into a red giant star by then anyway, so we don’t need to worry – we’ll all be toast. (So much for Genesis 8:22)
I’m sure you are relieved to hear that there is NO nuclear reactor accumulating fissionable amounts of unstable isotopes at the centre of our fair planet 🙂
As for the atmosphere – global warming has so far caused a relatively small overall increase in global atmospheric temperature. Yes, it is sufficient to cause accelerated melting of the ice caps and glaciers, but it is not enough to prevent the cooling of the mantle.
Has volcanic activity increased recently? In the last four decades, between 50 and 70 volcanic eruptions were recorded per year. Since 1790, the average number of large eruptions per year is between 1 and 4. There is no evidence that inefficient cooling of the mantle might be causing a greater number of volcanic eruptions. (There is some research available that suggests that melting glaciers remove pressure on the mantle, and this may cause increased up-welling of mantle material, and increased volcanic activity).
Global warming is a threat to the way humans and animals currently live on earth. Rising sea levels will flood coastal towns and drown small islands. Many species will no doubt become extinct unless they can adapt to a warmer environment, and those that DO adapt will become more plentiful.
The threat is to the inhabitants of the Earth, NOT to the Earth itself. “Mother Earth” will continue to exist – she has survived meteor strikes, strikes by minor planets, blasts from supernovae, magnetic field reversals, solar mass-ejections, super-volcanoes and more. She can survive the loss of our greedy, violent species, along with many others, and continue on in her orbit about her bright yellow star, for many millennia to come.
Global warming is a HUMAN problem. WE are the ones who will suffer, and it’s up to US to do something about it. The alternative is to adapt, along with the other animals….

P.S. Tom Chalko’s ideas are the wierdest Global Warming-related ideas I’ve ever come across.
If you have heard of any other strange ideas about the changing climate, please leave a comment – I’d love to hear from you 🙂
