The Arid Lands themes: Climate effects of a dried up sea.

As I have mentioned in a previous post, 6 million years ago (Ma) the Mediterranean Sea entered a phase of desiccation when it became cut off from the Atlantic, and almost completely dried up. This is the same scenario I have envisioned for the alternate future world of The Arid Lands, where Inez and her people struggle to survive, not knowing that everything is about to change.

The desiccation of the Mediterranean Sea would have a number of knock-on effects for the climate of the surrounding lands as well as creating a unique environment in the basin itself.

The climate of the basin can only be speculated for no equivalent environment exists on Earth today. But it is likely that as the depth of the basins increased so did the temperatures, possibly reaching summer midday highs of as much as 80C at its deepest points. This would not allow the existence of permanent life and it is likely that temperatures were nowhere near this extreme. But they would have been elevated enough to make life there extremely uncomfortable and difficult.

The surrounding areas would also experience climatic changes. Currently evaporation from the Mediterranean Sea provides moisture to the atmosphere which drives rainfall across much of the surrounding areas. With the Sea drying up there would be no input of moisture to the atmosphere and these rains would fail, resulting in a significantly drier climate over most of the central and eastern mediterranean belt.

In fact, the Mediterranean climate that we associate with Greece, Italy and the Levant would exist only in the Iberian Peninsula and NW Africa.

The desiccation would result in the extinction of much of the marine flora and fauna native to the basins, but the fusing of the two land masses would allow dispersal of terrestrial animals across the region.

Inez’s people survive by fishing for shrimp in the brine pools. In truth such a hypersaline environment would be hostile to life, but life is adaptable and my poor basin dwelling people have to eat something. Hence the shrimp. But apart from that I’ve tried to keep the environment in which they live as plausible as possible.

So how did this scenario arise in the world I have created? That will be the subject of a future post on this blog.

The Arid Lands is available from Amazon in both kindle and print format.

Review: Hot Ash and the Oasis Defect by Philip Wyeth

The Book

Welcome to 2045. Automation has freed humanity from the drudgery and limitations of blue-collar labor. For twenty years, a remarkable group of female bureaucrats has overseen an ambitious construction program that is spreading equity, prosperity, and peace worldwide.

But Detective Ashley Westgard of the Jacksonville Police Corps senses that beneath all the glimmer and shine, a new malaise has taken root in society. From brazen acts of criminality and rampant party pill abuse, to her own insatiable desires... All is not well on the road to paradise.

Ash is beautiful, vain, headstrong, and erratic. A symbol of her time as she careens from impulsive shopping sprees to drunken fights to escapades of sin. But now that a methodical killer is on the loose, she must rise above apathy and doubt in order to forge her raging inner fire into a fearsome weapon of justice.

My Thoughts

This is a futuristic detective story with a pulpy feel and a noir vibe. The story charges along at pace and the twists and turns keep you guessing. I read it in one sitting. The world the author has created is immersive and there is a strong sense of place.

The only criticism I have is Ash herself. This book is clearly written by a man from a female POV. At times I felt that Ash was more of a man’s ideal of what a feisty woman should be like, rather than someone who, as a female myself, I could relate to.

But unless that really bothers you it won’t distract from what is at heart a fun romp. I thoroughly enjoyed reading this. It’s short, but it’s entertaining.

The Arid Lands themes: The Messinian Salinity Crisis

My newly released SF novel, The Arid Lands is set some 600 years from now, in an alternate future when the Mediterranean has almost completely dried out. It is in this inhospitable landscape of salt flats and occasional pools of hypersaline brine that Inez and her people struggle to survive. Inez knows no other existence. But all that is about to change.

You may think that the idea of a vast sea such as the Mediterranean almost completely evaporating is pure fiction, but let me tell you, it is not. For the Mediterranean Sea did indeed dry out, albeit a long time ago.

About 6 Million years ago (Ma) the Mediterranean Sea became disconnected from the Atlantic Ocean. During the period that followed, known as the Messinian Salinity Crisis the sea almost completely evaporated.

The closing of the connections between the Mediterranean and the Atlantic Ocean, which is now the Straits of Gibraltar, was caused by the shifting tectonics in this region. This isolation of the Mediterranean from the main inflow happened several times, between 6 and 5.3 Ma.

The initial phase was one of repeated cycles of evaporation and replenishment which led to the formation of thick sequences of evaporite deposits, minerals such as halite and gypsum, deposited from the evaporating seawater.

The connection was then cut off for a prolonged period of time. During this later episode of desiccation, the Mediterranean became a dry basin, as much as 5 km deep, with only a few hypersaline pockets of water remaining. This process of drying out the Mediterranean Sea is estimated to have taken about 1000 years.

The Mediterranean remained dry until 5.3 Ma when the Straits of Gibraltar were finally breached, and water flooded back into the Mediterranean basin in the form of a cataclysmic flood, and so the Mediterranean Sea as we know it today was formed.

But the thick evaporite deposits and the presence of deep canyons in the seabed which cut down into the abyssal plains as water returned to the sea are testament to this arid phase in the Mediterranean Sea’s history.

This is the setting for The Arid Lands. A hostile environment that once really existed. I will talk more about this geological event and how it inspired the world I describe in The Arid Lands in future posts on this blog.

The Arid Lands is available from Amazon in both kindle and print format.
