How Our Planet Came to Life

I recently read a very interesting book on the history of our Planet Earth, Becoming Earth: How Our Planet Came to Life by Ferris Jabr. Life of various forms, microbes, fungi, plants, animals, etc., has had a large impact on climate, earth’s crust, the composition of the atmosphere, the oceans, and still do. This fact filled book is about this four and half billion history. Below is my review of the but first something about the book formats.

Amazon’s Description of Becoming Earth

NEW YORK TIMES BESTSELLER • A vivid account of a major shift in how we understand Earth, from an exceptionally talented new voice. Earth is not simply an inanimate planet on which life evolved, but rather a planet that came to life.

“Glorious . . . full of achingly beautiful passages, mind-bending conceptual twists, and wonderful characters. Jabr reveals how Earth has been profoundly, miraculously shaped by life.”—Ed Yong, Pulitzer Prize winner and bestselling author of An Immense World

FINALIST FOR THE LOS ANGELES TIMES BOOK PRIZE • FINALIST FOR THE OREGON BOOK AWARD • AN AMERICAN LIBRARY ASSOCIATION NOTABLE BOOK OF THE YEAR

A BEST BOOK OF THE YEAR: Smithsonian, Chicago Public Library, Booklist, Scientific American, Nature

A BEST BOOK OF THE SUMMER: The Atlantic and NPR’s Science Friday

One of humanity’s oldest beliefs is that our world is alive. Though once ridiculed by some scientists, the idea of Earth as a vast interconnected living system has gained acceptance in recent decades. We, and all living things, are more than inhabitants of Earth—we are Earth, an outgrowth of its structure and an engine of its evolution. Life and its environment have coevolved for billions of years, transforming a lump of orbiting rock into a cosmic oasis—a planet that breathes, metabolizes, and regulates its climate.

Acclaimed science writer Ferris Jabr reveals a radical new vision of Earth where lush forests spew water, pollen, and bacteria to summon rain; giant animals engineer the very landscapes they roam; microbes chew rock to shape continents; and microscopic plankton, some as glittering as carved jewels, remake the air and sea.

Humans are one of the most extreme examples of life transforming Earth. Through fossil fuel consumption, agriculture, and pollution, we have altered more layers of the planet in less time than any other species, pushing Earth into a crisis. But we are also uniquely able to understand and protect the planet’s wondrous ecology and self-stabilizing processes. Jabr introduces us to a diverse cast of fascinating people who have devoted themselves to this vital work.

Becoming Earth is an exhilarating journey through the hidden workings of our planetary symphony—its players, its instruments, and the music of life that emerges—and an invitation to reexamine our place in it. How well we play our part will determine what kind of Earth our descendants inherit for millennia to come.

My five-star review for Becoming Earth

A Page Turner for People with a Curious Mind

This book gives us a brief overview of the natural history of Earth, emphasizing that not only is life impacted by geological forces, but life is influencing and even creating the composition of the atmosphere, impacting climate and even affecting geological forces. The author explains how microbes, plants, and animals transformed the planet. He is explaining how humans are transforming planet Earth and its climate through fossil fuel consumption, agriculture, and pollution. He is noting that we have altered more layers of the planet in less time than any other species, pushing Earth into a crisis. The author promotes the idea that Earth itself is a living organism (Gaia hypothesis). I am not sure if I entirely buy that idea, but he makes a good case for it.

The book covers a lot of history. Earth is four and half billion years old and a lot has happened. As a result, there are no deep dives into topics. However, the book is filled with hundreds of interesting facts and information, which makes the book a page turner to anyone with a curious mind. One major example of this is that about three billion years ago Cyanobacteria evolved a new type of photosynthesis that used sunlight, water, and carbon dioxide to create energy, while releasing oxygen as a waste product. This transformed the atmosphere and enabled complex life by allowing aerobic respiration to evolve. This invention turned the sky blue, gave us the protective ozone layer, but also caused climate change (snowball Earth) resulting in massive extinctions.

However, there is much more. Another example is that microbes helped transform Earth’s crust. During the first half billion years of Earth’s history, Earth was a water world save for volcanic islands. Trees communicate and assist each other via fungi (Mycorrhizas). Phytoplankton produces 50% of all oxygen, the invention of the Haber-Bosch process more than doubled the world’s crop harvest, there once was 30-60 million Bison roaming the plains, humans now emit 60 to 120 times more carbon dioxide each year than all the world’s volcanoes.

As I mentioned there are hundreds more interesting facts. He also presents a lot of facts and information regarding the destruction of the environment, which may not sit well with everyone. However, I think it is important information. The book includes a large number of references for further reading.

The book is well written and well organized and included fun personal anecdotes. It was easy and entertaining reading and like I said, it is a page turner to people with a curious mind. I loved this book and I highly recommend it.

The Extinction Rate is Much Higher Than the Natural Baseline Rate

Super fact 71 : Based on the fossil record today’s extinction rate is hundreds, or even thousands, of times higher than the natural baseline rate.

Animals included in the watercolor painting include Teratorm, Mammoth, Macrauchenia, Glyptodon, Smilodon, and Andrewsarchus. | The Extinction Rate is Much Higher Than the Natural Baseline Rate — Collection of watercolor prehistoric and now extinct animals isolated on a white background. Hand painted illustration of Ice Age. Asset id: 2169205593 by Ekaterina Glazkova

Estimating the extinction rate is a complicated task that requires some assumptions and estimations. This article from the National Library of Medicine use what it claims to be conservative estimates, which would tend to minimize evidence of an emerging mass extinction. Despite that fact the average rate of vertebrate species loss over the last century is up to 100 times higher than the extinction rate without/before humans (background rate). Other sources claim an extinction rate that is 1,000 or even 10,000 the background rate.

To put some specific numbers on what a high extinction rate means, scientists count 881 animal species are known to have gone extinct since around 1500. If we include animal species that scientists suspect might be extinct, that number shoots up to 1,473. You can read more on the issue here or here or here.

Benjamin, the last Tasmanian Tiger, died in 1936 in the Beaumaris Zoo in Tasmania. Baker; E.J. Keller., Public domain, via Wikimedia Commons

What is clear is that the current extinction rate is much higher than what is typical and we humans are the cause. This came as a shock to me the first time I found out about it, and it is certainly an important topic, and therefore a super fact. It is true, surprising to many, and important.

Those who want to minimize the problem with the ongoing extinctions often point out that extinctions are a natural part of evolution and that throughout Earth’s history up to around 98% of all species that have ever existed are now extinct. In my opinion, that argument fails to consider the enormity of Earth’s four billion year natural history. A lot of evolution happened during that time.

Modern humans have only been around 300,000 years, or 0.0075% of that time, a tiny blip in time. Human civilization has only been around for 12,000 years, or 0.0003% of that time, an even tinier blip in time. Like comparing an ant head to a mile. Us having a large negative impact on the natural world in such an extremely short time is quite notable.

By considering the extinction rate you get a better idea of the scope of the problem. The fact that the extinction rate today is significantly higher than the expected natural rate and that the primary cause of modern extinctions is human impact as opposed to natural phenomena, makes it a case for concern.

The Five Past Mass Extinction Events

Over the last 440 million years life on Earth has experienced five so called mass extinctions. A mass extinction event is when at least 75% of the world’s species are lost during a short period of time – geologically speaking. This period is not clearly defined but often defined to be two million years. Two million years may seem like a long time, but geologically speaking, it is a short time.

The five mass extinction events were:

Late Ordovician mass extinction (444 million years ago; mya)
Late Devonian mass extinction (360 mya)
Permian–Triassic extinction event (250 mya)
End Triassic extinction event (200 mya)
End Cretaceous (65 mya) – the event that killed off the dinosaurs.

Below is an overview of the five big mass extinctions in Earth’s history. The graph is from Our World in Data.

The graph shows extinction rates going up and down with five tall peaks representing mass extinction events. — The Big Five Mass Extinctions in Earth’s History. A mass extinction is defined by the loss of at least 75% of species within a short period of time (geologically, this is around 2 million years). Extinctions are a natural part of evolution, but background rates are typically less than 5 families extinct per million years. Sources Barnosky et al (2011). Howard Hughes Medical Institute: McCallum (2015). Vertebrate biodiversity losses point to a sixth mass extinction. From Our World in Data.

Biodiversity experts have estimated that about 30% (uncertainty range: 16–50%) of species have been globally threatened or driven to extinction since the year 1500. 30% globally threatened or extinct is not 75% that are actually extinct, but in just 500 years that looks like a quick start on a mass extinction. It should be noted that 500 years is just 0.025% of two million years. Issues such as deforestation, chiefly the result of replacing forests with agriculture, overexploitation, and global warming / climate change are driving extinctions and represent big biodiversity threats in the near future.

Angalifu died of natural causes at the age of 44 on 14 December 2014. Sheep81, Public domain, via Wikimedia Commons.

This is why there is talk about the so called Holocene or Anthropocene extinction and it possibly being a sixth mass extinction, this one being human caused. It should be noted that there are credible sources that question whether we are at the cusp of a sixth mass extinction event.

Posting this on Thanksgiving Day may seem awkward. However, whether there will be a human caused sixth mass extinction or not depends on us, and it looks like more people want to protect our natural world. Many animals, such as the giant panda, bald eagle, the sea otter, black footed ferret, the Peregrine falcon, the blue whale, Rodrigues fruit bat, the Island night lizard, and the California condor, have been saved from extinction through conservation efforts like habitat restoration, anti-poaching laws, captive breeding programs, and reintroduction to the wild. Perhaps we are turning things around. We should give thanks to all who care.

Former President George W Bush

Daily writing prompt

Who is the most famous or infamous person you have ever met?

View all responses

Today’s daily writing prompt is “Who is the most famous or infamous person you have ever met”. That is former President George W Bush. In 2010 I met him at a Barnes and Noble book signing event here in northern Dallas where I live. It is also where he lives. He was selling and signing his book Decision Points. I bought four books, but he only signed a maximum of two books. Hundreds of people, perhaps thousands, wanted to have signed books and the security was rigorous, so signing a lot of books for each person was not practical.

I should say that at the time I was an admirer of George W. Bush, but I have a more nuanced understanding of him at this point. I have to admit I have not read his book yet. It has been sitting in my bookshelf for 15 years. I have a substantial TBR list and I have to admit that I might have bought the book for other reasons than reading it. But I will eventually get to it.

Senator Ted Cruz

Another famous person that I’ve met is Senator Ted Cruz and in this case the contact was a bit more substantial. I am a member of a non-partisan organization that seeks to create political will for solving the climate crisis. They are called Citizens Climate Lobby, or CCL. We find bi-partisan legislation and try to get both Democrats and Republicans onboard with it and we have been fairly successful. I am the CCL liaison for Senator Cruz office and have had the pleasure to meet him in person a couple of times. We shook hands, talked, and took photographs with him.

United States is Tornado Country

Super fact 65 : The United States covers approximately 6.14% of Earth’s total land area. Despite that approximately 75% of the world’s tornadoes occur in the United States, making the risk of a tornado in the US 46 times higher than in the rest of the world. Tornadoes are particularly common in Tornado alley. Canada is the country with the second-highest number of tornadoes globally.

Our neighborhood was ravaged by an EF3 tornado in the evening of October 20, 2019. Today is the six year anniversary of that event. One year ago, I was interviewed by the NBC about this event. Yes, I was on TV. NBC had found me via my Leonberger dog blog. I’ve included the clip below.

It appears that the most common statistics stated by reliable sources is that approximately 75% of the world’s tornadoes occur in the United States (click here, here, or here). As stated, 75% is an approximate number and another common number is 90%. 90% might be overstated because smaller tornadoes are underreported in the rest of the world. Whether the correct number is 75% or 90% it is clear that the United States has the most tornadoes. It is the Tornado Country of the world.

It is quite astonishing that one country, the United States, has such a high concentration of this extreme weather phenomenon. Most Americans know that their country is special in this regard. I’ve met a lot of Europeans (I am from Europe / Sweden myself) who thinks tornadoes is just Hollywood thing. However, it is a real and very common phenomenon in the United States, and that is surprising to much of the rest of the world. It is also an important extreme weather phenomenon that kills a lot of people and causes billions of dollars in damage every year. This is why I consider “United States is Tornado Country” a super fact.

Tornado Alley

Tornadoes can happen anywhere, but as mentioned they are more common in North America and especially in tornado-alley. Despite tornado alley’s small size, a quarter of all significant tornadoes in the world occurred there according to a study (1921 – 1995). The extent of tornado alley includes north Texas, Oklahoma, Kansas, Nebraska, South Dakota, Iowa, and the corners of Minnesota, Wyoming, Colorado and New Mexico. Dallas, where we live, is in Tornado Alley.

Dixie Alley

Another region with a lot of tornadoes is Dixie Alley. Dixie Alley stretches from eastern Texas and Arkansas across Louisiana, Mississippi, Tennessee, Alabama, Georgia, and mid to western Kentucky to upstate South Carolina and western North Carolina; the area reaches as far north as southeast Missouri.

Dixie Alley has fewer tornadoes than Tornado Alley, but they tend to be deadlier and more violent than in Tornado Alley. The tornadoes in Dixie Alley occur year-round, at night, and the Tornadic storms in Dixie Alley are often high precipitation supercells due to an increase of moisture from proximity to the nearby Gulf of Mexico. The heavy rain makes it difficult to detect the tornadoes. Dixie Alley also has more mobile homes, homes tend to not have basements, and it is more densely populated than Tornado Alley. NOAA records indicate that the majority of deaths from tornadoes in the US have occurred in Dixie Alley.

Tornadoes and Hurricanes Are Different

Another related issue that has been brought to me is that many Europeans do not know the difference between a hurricane and a tornado. This is not strange since both of these extreme weather phenomena are less common in Europe.

A hurricane is a big rotating storm system originating in the ocean that sometimes makes landfall and devastates our coasts. Hurricanes are big, thousands of square miles and even a million square miles. A hurricane has wind speeds of 74 miles per hour (mph) or higher. That’s 119 kilometers per hour or 33 meters per second. They are called hurricanes in the Atlantic and the northeast Pacific, and Typhoons in the northwest Pacific, and otherwise just cyclones.

Satellite photo of Mexico, southeastern United States and the Caribbean. A hurricane is approaching from the east. | United States is Tornado Country — Satellite photo of hurricane approaching Cuba and Florida. Stock Photo ID: 2202605185 by Emre Akkoyun.

A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cloud. They originate with thunderstorms, especially supercells, and are more of an inland phenomenon even though hurricanes can sometimes generate tornadoes. Tornadoes are much smaller than hurricanes in area, almost always much smaller than a square mile, or just 10 or 30 meters across. The reason they can be as deadly as hurricanes is that they tend to have stronger winds and they appear and disappear quicker thus taking people by surprise.

So, in summary, Hurricanes cover a large area and lasts a long time. They come from the sea and devastate coastal areas and are less common than tornadoes. Tornadoes are formed on land from thunderstorms, typically supercells. They are particularly common in tornado-alley. They cover a small area and go high up into the air forming a funnel and are commonly more intense. They are also more common, and they can surprise people. Therefore, on average, tornadoes cause more deaths in the US than hurricanes. You can read more about it here.

Our Tornado Experience

As mentioned, on October 20, 2025, our neighborhood was ravaged by an EF3 tornado. I was sitting outside in the backyard drinking a beer (Yellow Rose from Lone Pint brewery) when the sirens went off and my cell phone started screaming tornado warning “seek shelter immediately”. I did not see any problem, so I thought it was just one of unnecessary warnings again and I wanted to finish my beer. However, I decided to walk back into the house. About one minute later there was a lot of noise and a piece of the neighbor’s roof flew into our chimney, smashed it and it started raining bricks.

The house shook and thought to myself, “that was some thunderstorm”. I opened the door to the backyard, and I was astounded when I saw the devastation. My backyard was covered in debris, bricks, trees, garbage, my grill had flown off, several of our neighbors’ houses were just rubble. I guessed it must have been a tornado. My wife Claudia told me to go and check on her parents who lived about a mile away. I started driving my Toyota Prius, but I did not get very far because a neighbor’s roof was lying across the road. We live on a circle, so I decided to go the other way instead but about 30 trees lying across the road stopped me. So, I started walking but four firemen stopped me and told me that it was too dangerous to walk around. I had to go home. We would later learn that my wife’s father was injured. I am describing this in the NBC interview below.

We lost power for four days, we needed a new roof and a new chimney, the wiring and piping (for air conditioning) in the attic was destroyed, the fence and garage door were broken. It cost $50,000.00 to repair, nut our house stood, the frame was fine, and luckily our insurance paid for all of it, except for the parasol the flew away. We had no proof it ever existed. Not everyone was that lucky, especially those whose houses were destroyed. Unfortunately, our Leonberger dog Bronco had a heart failure one week after this. However, he recovered. But we are guessing that the fact that we did not have air conditioning for a while could have affected his heart. It was a tough day for Bronco, our Leonberger Dog. <<Link-13>>

My Interview with NBC

As I mentioned, last year NBC interviewed me about this event. They said that they had been reading my Leonberger blog and were interested in a post that I had made about the tornado in Dallas on October 20, 2019. They wanted to interview me and asked for permission to use a few of my photos.

I would like to stress that there are thousands of people whom they could have interviewed. Thousands of people who probably would have been better candidates. What made all the difference was the post I made on my blog. Therefore, fellow bloggers, perhaps this is an example of the fact that blogs bring attention.

Threats To Coral Reefs What Can Be Done

I am not a super fact hunter today. This post is about an interesting book that I recently finished reading, “Life on the Rocks: Building a Future for Coral Reefs by Juli Berwald”, a prominent marine biologist based in Austin, Texas. Coral Reefs are underappreciated. They are extremely important to the ocean’s ecosystems. A fourth of all marine species depend on the reef at some point in their life. Coral reefs are also very important to us humans for a variety of reasons.

Unfortunately, today’s coral reefs are assaulted by a host of environmental stresses. The largest is climate change, or if you call it global warming, which is warming marine ecosystems even faster than those on land. 75% of the reef building corals in the world have already been damaged by high seawater temperatures. This book is about corals, what they are, how they live and evolve, their DNA, and what is being done to save the coral reefs. The book is heavy on the science at the same time as it is not tough reading. She is a great author as well as scientist.

Amazon’s Description of Life on the Rocks

FINALIST FOR THE L.A. TIMES BOOK PRIZE

NAMED A BEST BOOK OF THE YEAR BY THE NEW YORKER AND BOOKLIST

The story of the urgent fight to save coral reefs, and why it matters to us all

Coral reefs are a microcosm of our planet: extraordinarily diverse, deeply interconnected, and full of wonders. When they’re thriving, these fairy gardens hidden beneath the ocean’s surface burst with color and life. They sustain bountiful ecosystems and protect vulnerable coasts. Corals themselves are evolutionary marvels that build elaborate limestone formations from their collective skeletons, broker symbiotic relationships with algae, and manufacture their own fluorescent sunblock. But corals across the planet are in the middle of an unprecedented die-off, beset by warming oceans, pollution, damage by humans, and a devastating pandemic.

Juli Berwald fell in love with coral reefs as a marine biology student, entranced by their beauty and complexity. Alarmed by their peril, she traveled the world to discover how to prevent their loss. She met scientists and activists operating in emergency mode, doing everything they can think of to prevent coral reefs from disappearing forever. She was so amazed by the ingenuity of these last-ditch efforts that she joined in rescue missions, unexpected partnerships, and risky experiments, and helped rebuild reefs with rebar and zip ties.

Life on the Rocks is an inspiring, lucid, meditative ode to the reefs and the undaunted scientists working to save them against almost impossible odds. As she also attempts to help her daughter in her struggle with mental illness, Berwald explores what it means to keep fighting a battle whose outcome is uncertain. She contemplates the inevitable grief of climate change and the beauty of small victories.

My five-star review for Life on the Rocks

Interesting Science an Important Message and the Beauty of Corals

Coral reefs are incredibly important to the ocean and its ecosystems. A fourth of all marine species depend on the reef at some point in their life. Coral reefs are also very important to us humans for a variety of reasons. However, today’s coral reefs are assaulted by a host of environmental stresses. The largest is climate change, or if you call it global warming, which is warming marine ecosystems even faster than those on land. 75% of the reef building corals in the world have already been damaged by high seawater temperatures.

Our burning of fossil fuels also causes ocean acidification. The effects of ocean acidification have not yet damaged corals but will in the future. Add to that, hurricanes (getting worse due to climate change), diseases (SCTLD), pollution, fertilizer and sewage runoff, wild harvesting of corals for export, loss of urchins, illegal fishing, such as using explosives to catch fish (blast fishing), and cyanide. In 2009 70% of all fish in fish markets had telltale scars from explosions and in 2016 more than half the fish in aquarium shops tested positive for cyanide poisoning. The explosives and the cyanide destroy coral reefs. We know what’s causing the loss of coral reefs, but we also know how to solve these things: stop burning fossil fuels, manage fishing, prioritize sanitation, and control pollution.

This book will teach you about corals, that they are marine animal related to jellyfish and sea anemones, consisting of hundreds to thousands of tiny individual polyps that form colonies. That they are in a symbiotic relationship with photosynthetic algae called zooxanthellae. That the algae power the coral by making sugar and the coral provides the supplies the alga needs to make that power. They are 160 million years old.

You will learn about the history of the oceans pH level (acidity). different species, coral bleaching, hybridization and reticulated evolution. You will learn about the threats to corals and the efforts to save the coral reefs. The author is a distinguished scientist who does a lot of research and scuba diving. She takes you on an underwater (and above water) journey around the world, Florida, Sulawesi, Bali, Dominican Republic, and Australia, like Jacques Costeau used to do.

The efforts to save the corals include coral restoration, which is very difficult and expensive, coral farming, marine protected areas, aquarium hobbyists growing corals, cryobiology/ cryogenics, which is a futuristic technology involving freezing and later restoring corals in a better future. It should be noted that as warming events and coral bleaching events kill corals the ones that survive are better equipped to survive future warming. This is not so much adaptation as evolution by natural selection. Even though this can give you hope, one should remember that the current warming is very fast and even if evolution might save some corals, it changes the composition of coral species.

However, scientists have sequenced coral DNA and are trying to identify the genes that help some corals to survive warming events better than other corals. This could lead to assisted evolution. The author also addresses geoengineering techniques to slow down climate change such as marine cloud brightening, and she discusses the tragedy of the commons.

This book is full of facts and interesting science. However, it is not a difficult read. In addition, she makes it more colorful and personal by discussing her personal opinions on issues, her daughter’s mental illness caused by a lingering strep throat infection, her experiences with covid-19, and as mentioned, this book is organized as a journey around the world. I should mention that I felt that some of her personal opinions and personal stories may have been distractions, especially when I could not agree with what she said. But I thought that was a minor issue. She is a great author who knows how to keep an audience captivated despite all the science. She lists 292 references. It is a very well-written and interesting science book about corals. I learned a lot from reading this book. I highly recommend this book.
