7 Signs We Are Heading For A Mass Extinction

One day before our government shuts down, courtesy of the Conservative crime family, it would seem that the shutdown and debt ceiling crisis is the most dangerous event facing us, but this is only a short-term disaster compared with the likely mass extinction caused - and denied - by those same murderous gangsters.

In a story, ostensibly a science article, however having everything to do with the politics of the Conservative crime cartel, "7 Signs We Are Heading For A Mass Extinction," by Annalee Newitz at, we learn how Climate Change Denial may have hastened our doom.

As we've nervously watched the scene unfold for some time now, we see for once that Wikipedia misses the boat on the topic, as we see in their article on "Extinction risk from global warming," and we may be past the tipping point as the Conservatives, acting as paid lackeys to their corporate masters, have not only hidden the truth from the world, they've lied - just to line their own pockets even more.

But on to the article, especially noting the fourth and fifth signs, "Ocean Acidification" and "Climate Change":

"Today, many scientists believe we are on the cusp of a sixth mass extinction which could wipe out most life on Earth as we know it. Here are seven signs that they could be right.

"A mass extinction happens when over 75 percent of all species on the planet die in a period of less than two million years. That may sound long to you, but it's the blink of an eye in geologic time. There have been five mass extinctions on Earth over the past 540 million years, sometimes caused by catastrophic disasters, and sometimes by quiet, insidious events like invasive species taking over the planet.

"7. Earth Is Bubbling with Super Volcanoes

"Yellowstone Park in the United States is actually a volcano caldera, a thin cork of earth that sits on top of a massive cache of broiling magma. And this super-volcano could blow any time. The last time Earth witnessed an explosion of this size was in 1812, when Mount Tambora in Indonesia erupted so profusely that the Earth's climate cooled for several years afterwards. Even more frightening is the prospect that another kind of super volcano, called a large igneous province (LIP), could become active sometime in the future. A now-inactive LIP, called the Siberian Traps, erupted 250 million years ago. It spewed so much sulfur, carbon other greenhouse gases into the air that the Earth experienced a climate change catastrophe, vacillating wildly between extreme heat and cold until 95 percent of all life had died. This mass extinction was so bad it's been nicknamed "the Great Dying" by geologists. Yellowstone is not a LIP, but if it explodes into a super eruption, the damage will be incredible. Super volcanoes are an ever-present threat, that have haunted the Earth for millions of years.

"6. Invasive Species Are Everywhere

"On Earth, humans have aggressively invaded every continent except Antarctica, swelling our population to over 7 billion individuals and eating everything in sight. Like rats and cockroaches, we are the ultimate invasive species, pushing many creatures out of their native habitats — which could, ultimately, kill those creatures on a huge scale. Our population could grow a lot bigger before humans are endangered, but that doesn't mean we wouldn't harm other species. About 359 million years ago, 75 percent of all species on Earth died during the Devonian mass extinction. Geologist Alicia Stigall has evidence that this horrific slaughter was the result of invasive species like sharks (yes, there were sharks hundreds of millions of years ago) aggressively eating all the food in every environment — slowly starving all the creatures who depended on local food sources and couldn't move to new feeding regions.

"5. Climate Change

"The Arctic ice cap is shrinking. Temperatures are rising. Scientists across many disciplines and countries are united in their belief that the climate on Earth is getting hotter. The good news is that humans might not be the only cause of this climate change — the planet has suffered through dramatic shifts in temperature many times over its history. The bad news is that pretty much every time that happens there's a mass extinction. The Great Dying was caused by climate change. The very first mass extinction 540 million years ago, called the Ordovician Extinction, was set off by a rapid ice age followed by a rapid greenhouse period. Another mass extinction, at the end of the Triassic, was set in motion by an undersea super volcano and massive wildfires (like the ones in Australia, pictured from space in the image at the top of this post) that smothered the planet in smoke and ash. The meteorite that smashed into the planet before the dinosaurs were wiped out in a mass extinction? Nope, didn't kill those big guys with fire. It killed them by throwing so much debris into the atmosphere that the climate changed. Most geologists agree that when the climate changes, mass extinctions follow.

"4. Ocean Acidification

"Acid levels in the Earth's oceans are going up, which is what's killing all those reefs and making life hard for shellfish. Ocean acidification is also one major reason that the Great Dying was so, well, great. It was also a major part of the Triassic mass extinction 200 million years ago, which wiped out 80 percent of the planet's species — especially in the oceans. When the waters are too acidic, calcium levels go down. That means shelled creatures simply can't build their shells, and they die even before they have a fighting chance. When shelled creatures die, the predators who feed on them also die. And the more dead bodies you've got in the ocean, the more acidic everything gets. If Earth's oceans continue to become more acidic, mass extinction could be next.

"3. Extinctions Are Happening At A Higher Than Average Rate

"Extinctions are normal. In fact, statisticians who study extinction have figured out a typical "background extinction rate," which is the normal number of creatures who are going extinct at any given time. So a mass extinction is like a big statistical spike of death sticking up far over that background rate. And, unfortunately, there is a lot of evidence that the extinction rate we've experienced over the past 500 years is above the typical rate. No, this rate is nowhere near mass extinction levels. But it is going up. Which is exactly what you'd expect to see at the beginning of a mass extinction.

"2. All the Megafauna Are Dead

One way scientists figure out rates of extinction is by looking at the diversity of fossils. Based on this evidence, they can figure out how many creatures and plants were alive at a given time, plus how quickly (or slowly) they disappeared from the fossil record. In recent fossil records, from the past 50,000 years, we can easily see a steep decline in species diversity. The Earth was recently home to many species of so-called megafauna, from mastodons and giant wallabies, to giant sloths, and today they are entirely gone. When you see an entire category of creatures wink out that quickly (in geological time), it suggests more than just typical extinction patterns.

"1. Amphibians Are Dying Out

"Today, we are witnessing another giant group of species going extinct so rapidly we can actually measure it in human time, rather than geologic time. Amphibians, especially frogs, are dying out at such a fast pace that some have called the twenty-first century a time of "biodiversity crisis." Most have been felled by a fast-spreading, deadly fungus that kills whole communities of frogs in weeks. It's likely the fungus has reached pandemic proportions because frogs are being forced out of their habitats, and coming into contact with new species they might never have seen otherwise. Just as human pandemics spread more quickly due to travel, amphibian pandemics are spread when frogs move into a new area and infect previously unexposed communities. The more we lose our animal diversity, the closer we get to a world dominated by invasive species. And that scenario really didn't end well in the Devonian mass extinction. It probably won't end well for us, either.

"Still, as I explain in my book, Scatter, Adapt, and Remember: How Humans Will Survive a Mass Extinction, there is hope. These are early signs of a possible mass extinction, and we still have plenty of time to do something about it. We can curb fossil fuel emissions to prevent climate change from getting worse, and we can preserve biodiversity by maintaining natural areas where animals won't be edged out by human settlements. As for megavolcanos and meteorite impacts? Well, that's going to be a little harder. But it's not impossible. We can't bring the mastodons back, but we can still prevent most of the species around us (including humans) from dying out."


If you're not afraid enough, in another article by Rebecca Burn-Callander, Johannesburg, at The Telegraph (and you might take a look at the multitude of article now appearing in a simple search, "mass extinction climate change," -, "We’re facing a mass extinction event," claims Bob Geldof," we see the horrific scenario in its starkest terms:

Bob Geldof addressing the One Young World summit in Johannesburg

"Live Aid founder and activist Bob Geldof has warned that the human race may be extinct within 15 years because of climate change.

"'The world can decide in a fit of madness to kill itself,' announced Bob Geldof at the launch of the One Young World summit in Johannesburg. 'Sometimes progress may not be possible.'

"'We're in a very fraught time,' he added. 'There will be a mass extinction event. That could happen on your watch.'

"'The signs are that it will happen and soon.'

"Sir Bob, wearing his trademark sunglasses, addressed 8,000 One Young World delegates from 190 nations across the world in Soccer City, Johannesburg last night. He is a counsellor for the organisation, which hopes to inspire and create the next generation of global leaders.

"The Live Aid founder and one-time Boomtown rat announced that his generation has let down the young people of today. 'My generation has failed more than others. You cannot let your generation fail. The next war will not be a World War 1 or a World War 2, it will be the end.'

"Attendees shouted and blew on thousands of vuvuzelas as Sir Bob added: 'We may not get to 2030. We need to address the problem of climate change urgently. What are you going to do about it? Get serious. Some of the nations that arrived here so proudly will not be there to meet us.'

"However, the singer tried to inject a note of positivism into his gloomy predictions. 'Just because you may not believe that progress is possible, that should not prevent you from trying for it,' he said. 'The alternative is finality.'

"'We need to be more human. Less Irish. Less Cameroonian. Less Chinese. Less Russian. More human.'

"However, Sir Bob then disappeared down a philosophical route that baffled most of the audience, many of whom do not count English as a first language. 'The ordinary trouble of ordinary days doesn't seem to matter much,' he sighed. 'We are in the great existential age of our humanity. We somehow feel we've missed something's that’s greater than ourselves and we don't know what it is or how to find it.'

"He finished his address apologising for being 'bloody miserable'. 'Just get on with it,' he told delegates, before leaving the stage.


Are we overly alarmed or should we all wave goodbye to each other (after dealing appropriately with those who refused to admit Climate Change was a.] real, and b.] man-made)?

If you're not afraid for your sake, or for your children or grandchildren, you should be.  The Conservative criminal cartel may have found a way to win, taking themselves down with them.
