What Does a Big Tsunami Really Look like?

The Doomsday Book has a chapter on tsunamis (as well as super-tsunamis caused by nuclear bombs). But what does a tsunami really look like to the people experiencing it? This documentary, made mostly from the videos that tourists and residents captured in the 2004 “Boxing Day Tsunami”, shows the horror as it unfolds for the people on the ground:

Tsunami – Caught On Camera [full program] 12/26/2004

200,000+ people perished in this single tsunami.

Simulation of a Nuclear Blast in a Major City

An asteroid strike is one kind of doomsday scenario. Depending on the size of the asteroid, it could mean anything from “shooting star” to a mass extinction event. But, fortunately, large asteroid strikes are rare.

A nuclear bomb strike, on the other hand, is far easier to imagine. Humankind has thousands of nuclear bombs in its national nuclear bomb warehouses. There is also the threat that terrorists get hold of a nuke somehow and target a city. Either way, this video shows what a nuclear bomb doomsday scenario would look like for a major city:

Not good. One way of another, humanity must understand and gain control of the nuclear bomb problem.

There’s 14 million metric tons of microplastics sitting on the seafloor, study finds

We know that there are big pieces of plastic floating in the ocean: plastic bags, plastic cups, plastic straws, plastic bottles, “ghost gear” (abandoned fishing nets and other equipment), etc. We know that these big pieces break down into smaller pieces floating in the ocean. But it gets even worse:

There’s 14 million metric tons of microplastics sitting on the seafloor, study finds

Justine Barrett from CSIRO’s Oceans and Atmosphere who led the study, said in a statement that, “Even the deep ocean is susceptible to the plastic pollution problem.”

“Plastic pollution that ends up in the ocean deteriorates and breaks down, ending up as microplastics,” she said. “The results show microplastics are indeed sinking to the ocean floor.”

Scientists have called plastic litter “one of this generation’s key environmental challenges” and the problem is an internationally recognized environmental issue. Plastic is a persistent pollution that hurts wildlife, the ocean itself and there’s growing concern about the potential health risks it poses to humans.

It is difficult (but possible) to imagine somehow filtering floating plastic bits out of the water. Maybe we can invent enormous robot whale sharks that do it. The problem is so immense though that we would need a million of these robots.

But filtering plastic out of ocean sediments? How do we do that? Maybe we invent another robot, but still… The disruption to the ocean environment will be immense, and the robot will need to sort the plastic bits out of the sand and mud bits.

The article points out that the problem will only gets worse. And then you watch videos like this and see immensity of the problem in underdeveloped countries:

Fixing this doomsday problem will take a massive worldwide effort, and this is just one of the doomsday problems humanity faces.

Amazon near tipping point of switching from rainforest to savannah – study

The Doomsday Book has a chapter on Rainforest Collapse and all of the tragedy that the collapse will bring to our planet. This article reinforces the dire situation we face:

Amazon near tipping point of switching from rainforest to savannah – study

Much of the Amazon could be on the verge of losing its distinct nature and switching from a closed canopy rainforest to an open savannah with far fewer trees as a result of the climate crisis, researchers have warned.

One big problem is that the conversion of the forest to savannah means a massive tree die off. Every tree that dies releases its stored carbon dioxide into the atmosphere, meaning ever rising CO2 levels in the atmosphere and warmer temperature across the globe. It is a horrible positive feedback loop that will eventually make earth’s equitorial regions uninhabitable.

Three Scenarios for the Future of Climate Change

Three Scenarios for the Future of Climate Change

Had the words of either man been heeded in the intervening three decades, the world today would be a very different place—incalculably better off in innumerable ways. Instead, during that interval, some two hundred billion metric tons of carbon have been spewed into the atmosphere. (This is roughly as much CO2 as had been emitted from the start of the Industrial Revolution to that point.) Meanwhile, trillions of dollars have been sunk into coal-burning power plants, oil pipelines, gas pipelines, liquid-natural-gas export terminals, and a host of other fossil-fuel projects that, in a saner world, would never have been constructed. And global temperatures, as everyone can by now attest—though some still refuse to acknowledge—have continued to rise, to the point where the sweltering summer of 1988 no longer stands out as particularly hot. The nineteen-nineties were, on average, warmer than the eighties, the aughts hotter than the nineties, and the past decade hotter still. Each of the past five years has ranked among the warmest on record.

And the future does not look good:

What’s technically referred to as “dangerous anthropogenic interference with the climate system” and colloquially known as “catastrophe” is warming so dramatic that it’s apt to obliterate whole nations (such as the Marshall Islands and the Maldives) and destroy entire ecosystems (such as coral reefs). A host of scientific studies suggest that a temperature increase of two degrees Celsius (3.6 degrees Fahrenheit) or more would qualify. A great many studies suggest that warming of 1.5 degrees Celsius (2.7 degrees Fahrenheit) would be enough to do the trick. At current emissions rates, the 1.5-degree threshold will be crossed in about a decade. As Drew Shindell, an atmospheric scientist at Duke University, told Science, “No longer can we say the window for action will close soon—we’re here now.”

It is crazy that humanity is allowing this to happen. The effects will be so cataclysmic, will destroy so much infrastructure and property, ruin the lives of so many people… how can we as a species stand by and allow it to happen without stopping ourselves?

The Doomsday Book is one attempt to help us come to our senses. There are 6 chapters in the book on the climate change catastrophe that is coming.

Attenborough no longer minces words nor leaves his viewers wondering where he stands on the issue of climate change. In the new film, he laments Earth’s decline and states emphatically, “Our planet is headed for disaster.”

Russia’s Super-Tsunami Nuclear Weapon

This video goes into detail on Russia’s super-tsunami nuclear weapon, known as Poseidon:

Can Russia’s Doomsday Weapon Be Stopped? Status-6/Poseidon

If deployed, this weapon would be devastating to coastal cities. It is an unmanned robotic sub that carries a large nuclear warhead. It is nearly undetectable and can spend months to get to its target if need be. If detonated near a coastal city like New York, both the tsunami and the blast itself would be incredibly destructive. It might also be used to destroy an entire carrier battle group at sea.

Justin Trudeau: ‘The World Is In Crisis, And Things Are About To Get Much Worse’

“The international approach we relied on since the second half of the 20th century was built on an understanding that countries would work together,” Trudeau said. “But now the same countries are looking inward and are divided. We need to recognize where we are. The system is broken, and the world is in crisis. And things are about to get much worse unless we change.”
