Una superficie como un campo de fútbol se erosiona cada cinco segundos

Está ahí, justo bajo los pies, pero subyacente en el sentido amplio de la palabra. Bajo los cimientos de las casas, los cines y las fábricas, sustentando las carreteras que llevan a las playas, nutriendo a los alimentos exquisitos, acunando los lagos y ríos.., pero la función de este recurso, no renovable, va más allá. “Los niños que han tenido la dicha de jugar con el suelo saben un poco lo que es, pero los de la ciudad no tanto. Y es nuestro aliado silencioso, la mayoría de la comida se produce ahí, y también es un almacén natural de carbono, asume más que la vegetación terrestre y la atmósfera juntas, y eso es importante contra el calentamiento global. Además de aguardar microorganismos que proporcionan biodiversidad”, resume con brevedad Ronald Vargas, secretario de la Alianza Mundial por el Suelo, consciente de que este recurso natural no capta tanta atención como el agua en el mundo.

The Fate of Planet Earth Lies in the Hands of Just Two Generations, Warns Climate Columnist David Wallace-Wells

The global impacts of global pollution are so terrifyingly vast and all-encompassing that fully comprehending the potential consequences can prove difficult for the human mind. 

If it continues unchecked, scientists warn1 of an increase in extreme weather including rising sea levels, intensified and more frequent wildfires, devastating flooding, stronger hurricanes and prolonged droughts — all of which are projected to have colossal and costly impacts on public health, agriculture, politics, economic growth and human migration. 

But there’s good news: Humans have the power to stop, and potentially reverse pollution, but only if appropriate action is taken immediately, and on a global scale. 

While most people think of the burning of fossil fuels as the primary driver of pollution, data point to industrial agriculture as the greatest contributor of greenhouse gas emissions. An estimated 44% to 57% of all greenhouse gases come from the global food system. This includes deforestation, agriculture, food waste and food processing, packaging, refrigeration and transportation.2

So, while some argue that, in addition to curbing greenhouse gas emissions and transitioning to 100% renewable energy, implementing new and costly carbon-capturing technology3 is the solution, mounting evidence points to a less costly and more natural solution: Harnessing the power of Mother Nature. 

This includes organic regenerative agriculture,4 which promotes soil health, biodiversity, soil carbon sequestration and large-scale ecosystem restoration such as reforestation and the restoration of peatlands, mangroves, salt marshes and other important ecosystem habitats capable of drawing down and storing excess atmospheric carbon.5

Climate Columnist: ‘The Main Driver of Future Warming Is What We Do Now’

What happens on Earth within the next century in regard to climate change depends on the action humans do or don’t take, said David Wallace-Wells, deputy editor and climate columnist for New York magazine, in a recent interview on the Joe Rogan Experience podcast. 

Wallace-Wells, who wrote “The Uninhabitable Earth: Life After Warming,”6 says we tend to think about climate change as something that began centuries ago during the Industrial Revolution, but the truth is that in the history of mankind, 50% of all the carbon we’ve released into the atmosphere from the burning of fossil fuels has occurred within the last 30 years.7

That means the fate of the entire planet may lie in the hands of just two generations, because what happens in the next 50 to 100 years from now will depend on how humans address climate change today, Wallace-Wells says.

Deadlier Wildfires in California

In the featured video, Rogan and Wallace-Wells discuss how climate change is worsening wildfires in California, causing the fires to burn hotter and more frequently. Science shows California wildfires could get up to 60 times worse as climate change intensifies, says Wallace-Wells. 

That’s an alarming prediction considering California, in the past two years, had some of the most destructive fires on record. In fact, the Mendocino wildfire in July 2018 was the state’s largest ever, causing 60% more damage than any fire before it.8

There are a number of ways in which climate change may be intensifying California wildfires. For starters, hotter temperatures can create a drying effect, turning once-green vegetation into flammable wildfire fuel. Secondly, scientists say climate change is shortening California’s rainy reason, and shifting the Santa Ana winds in a way that fan deadly wildfires in Southern California. 

In the podcast, Rogan says a firefighter once told him that with the right wind, it’s only a matter of time before a fire hits the top of Los Angeles, California, and burns all the way to the ocean, and there will be nothing anyone can do to stop it.

Development and urban sprawl are another reason wildfires could get a lot worse in California. When Native Americans stewarded the land, they often performed controlled burns to prevent the buildup of timber, but because some of America’s wealthiest elite insist on living in the California hills, controlled burns are out of the question, says Wallace-Wells. 

His observation leads to an interesting statement about how the situation in California is unique in that climate change tends to impact the world’s poorest first. But in places like Bel-Air, a ritzy upper-class neighborhood in Los Angeles, the effects of climate change are working in reverse as it has largely been the ultrarich who are most affected by wildfires. 

The damage has been both destructive and costly. Just three California wildfires, the Camp Fire, Woolsey Fire and the Hill Fire, are estimated to have killed 88 people, damaged or destroyed close to 20,000 structures and caused more than $9 billion in damage.9 Those costs may be just the tip of the iceberg.

The Uninhabitable Earth

I. ‘Doomsday’

Peering beyond scientific reticence.

It is, I promise, worse than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible, even within the lifetime of a teenager today. And yet the swelling seas — and the cities they will drown — have so dominated the picture of global warming, and so overwhelmed our capacity for climate panic, that they have occluded our perception of other threats, many much closer at hand. Rising oceans are bad, in fact very bad; but fleeing the coastline will not be enough.

Indeed, absent a significant adjustment to how billions of humans conduct their lives, parts of the Earth will likely become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century.

Even when we train our eyes on climate change, we are unable to comprehend its scope. This past winter, a string of days 60 and 70 degrees warmer than normal baked the North Pole, melting the permafrost that encased Norway’s Svalbard seed vault — a global food bank nicknamed “Doomsday,” designed to ensure that our agriculture survives any catastrophe, and which appeared to have been flooded by climate change less than ten years after being built.

The Doomsday vault is fine, for now: The structure has been secured and the seeds are safe. But treating the episode as a parable of impending flooding missed the more important news. Until recently, permafrost was not a major concern of climate scientists, because, as the name suggests, it was soil that stayed permanently frozen. But Arctic permafrost contains 1.8 trillion tons of carbon, more than twice as much as is currently suspended in the Earth’s atmosphere. When it thaws and is released, that carbon may evaporate as methane, which is 34 times as powerful a greenhouse-gas warming blanket as carbon dioxide when judged on the timescale of a century; when judged on the timescale of two decades, it is 86 times as powerful. In other words, we have, trapped in Arctic permafrost, twice as much carbon as is currently wrecking the atmosphere of the planet, all of it scheduled to be released at a date that keeps getting moved up, partially in the form of a gas that multiplies its warming power 86 times over.
