415 PPM: We Are All Part of Exxon’s Unchartered Climate Experiment Now
By Andy Rowell
Earlier this month, we collectively walked into the unknown.
We are all now a living experiment. Never before in human history have carbon dioxide levels reached 415 parts per million.
These levels were last seen maybe some 2.5 to 5 million years ago, during the Pliocene, but then the earth was much warmer than it is today and it was way before us.
Back then, there was no Greenland and trees grew near the South Pole. Sea levels were much, much higher. Maybe 25 meters (approximately 82 feet) higher.
415 ppm is a grim number. It signals we are in deep, deep trouble. And in the words of Rolling Stone magazine: "Further evidence (as if further evidence were needed) of just how hell-bent we are on cooking the planet we live on."
To show you how much we are changing the climate: Every year another 2 to 3 ppm of carbon dioxide enters the atmosphere. Before the industrial revolution it was 280 ppm. And now it is 415 ppm.
We could have stopped the relentless rise of carbon dioxide, but we did not. In part the reason we collectively have failed to do so is the power of the oil companies and one of the most sophisticated public relations exercises ever undertaken to deny and obfuscate the truth.
The oil companies could have acted and kickstarted the renewable revolution, but they did not. But they knew. #ExxonKnew.
As Think Progress noted this week, one of the documents obtained by InsideClimate News into its investigation into what Exxon knew about climate science decades ago was an internal 1982 document from the Exxon Research and Engineering Company.
In this document the oil company mapped the "growth of atmospheric CO2 and average global temperature increase" over time.
Amazingly, as Think Progress highlights, "the company predicted that that, by 2020, carbon dioxide in the atmosphere would reach roughly 400 to 420 ppm. This month's measurement of 415 ppm is right within the expected curve Exxon projected under its "21st Century Study-High Growth scenario."
Exxon not only predicted the future, it also knew how bad it could be.
Not only did Exxon predict the rise in emissions, it also understood how severe the consequences would be, including warning of "considerable adverse impact" of rising carbon dioxide levels, including flooding and the melting of the Antarctic ice sheet.
Exxon knew all this, but instead of acting, went on to pour tens of millions of dollars into a massive disinformation campaign that we still see today being spouted by President Trump and Fox News.
No wonder climate scientists are alarmed at us reaching 415 ppm.
Professor Michael Mann told Think Progress, "If you do the math, we'll cross 450 ppm — which likely locks in dangerous planetary warming of more than 2°C/3.5°F — in just over a decade".
Peter Gleick, the president emeritus at the Pacific Institute for Studies in Development, Environment, and Security added: "Not that we need it, but the latest numbers are further evidence of the massive impact humans are having on our atmosphere and climate … We are entering an era never before experienced by humans."
Meteorologist and journalist Eric Holthaus noted on Twitter:
This is the first time in human history our planet's atmosphere has had more than 415ppm CO2.— Eric Holthaus (@EricHolthaus) May 12, 2019
Not just in recorded history, not just since the invention of agriculture 10,000 years ago. Since before modern humans existed millions of years ago.
We don't know a planet like this. https://t.co/azVukskDWr
We don't know a planet like this. We don't know what will happen, except that climate chaos will get worse. We do know the answers, though.
As Oil Change International pointed out yesterday, in yet another groundbreaking report, we have to stop drilling. It really is that simple. Not tomorrow. Not today. But yesterday. We need a just transition now.
Predictably, the denial in the Trump Administration continues: This week, Donald Trump's interior secretary said he had not "lost sleep over" over the 415 ppm figure.
David Bernhardt, who is a former oil and gas lobbyist, said, "I believe the United States is number 1 in terms of decreasing CO2." He added: "I haven't lost any sleep over it."
Meanwhile, just as Exxon warned that Antarctica would be in trouble, there is new research published showing just how bad things are.
According to new academic research published in Geophysical Research Letters, warming of the Southern Ocean now means that ice is being lost from Antarctic glaciers five times faster than in the 1990s.
It is yet another sign we are in deep, deep trouble.

Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
