Geomedia: Books: Exploring space is risky business

Space is deadly, and the explorers who risk their lives to venture farther into these depths rank among the bravest heroes of all time. In “Mankind Beyond Earth: The History, Science, and Future of Human Space Exploration,” Claude A. Piantadosi portrays the history and future of space exploration through the lens of space medicine, which reminds us of the many threats to the human body that await as we venture away from our planet.

Geomedia: Books: Earth faces challenges, but are they tipping points?

The 2016 book, “Tipping Point for Planet Earth,” by paleoecologists Anthony D. Barnosky and Elizabeth A. Hadly, is a serious book on a serious topic, and a well-written, one-stop resource for anyone who wants to understand a host of looming problems. The book focuses on the alarming number of worrisome planetary trends now underway, mainly as a result of the convergence of population growth and human-induced global warming. Chapters cover people (population growth), “stuff” (increased purchases of material goods), storms, hunger, thirst (failing water supplies, clean or not), toxins, disease and war. These trends have merited serious attention from environmental scientists and deserve the same from politicians. Whether they are tipping points, however, is a point of contention.

Geomedia: Mixed media: Geo-art collaboration shifts perspectives on earth materials

“Arts and Sciences.” The phrase is familiar to students and faculty on most campuses, often serving as the moniker of colleges or other curricular subdivisions within universities. While the pairing suggests a joint enterprise of some sort between the two fields, it might more aptly be termed, “Arts or Sciences,” as curricula rarely encompass both.

Geomedia: Books: Looking at the World Anew in "The Planet Remade"

Geoengineering, the deliberate large-scale modification of environmental processes on Earth, is often proffered as a solution to climate change. The transfer of carbon long sequestered in geologic repositories to the atmosphere has raised greenhouse gases to levels unprecedented in the history of our species. As a result, the average surface temperature and the heat content of the oceans have both increased.

Geomedia: Film: 'Written on Water': A Modern Tale of a Dry West

An endless patchwork of circular fields surrounds the small West Texas town of Olton. The unnatural shapes and sharp boundaries of the brown and green fields result from center-pivot irrigation systems that pull water from the Ogallala Aquifer and allow more crops to grow than the semi-arid landscape would otherwise allow. On these dusty farms and within town offices a drama is unfolding over what to do as irrigation wells run dry.

Geomedia: Radio: "The Infinite Monkey Cage" takes listeners to the edge of the universe and beyond

“Science is not about finding the right answer, it’s finding the least wrong answers,” quips physician and science writer Ben Goldacre, a guest on “The Infinite Monkey Cage,” a BBC radio show and podcast that casts an irreverent eye on big scientific questions. Goldacre was commenting on the definition of science, but this philosophy — that science is a constantly evolving pursuit, in which all ideas are valid until data and time prove them wrong — is also the refreshing and approachable premise of this witty show.

Geomedia: Film: Exploring Florida's aquifers with filmmaker Tom Fitz

Filmmaker Tom Fitz describes the first time he found himself sitting, alone, more than 20 meters below Earth’s surface and about 300 meters into an underwater cave: He was waiting in position to film a sequence of divers swimming through a narrow passageway as their lights illuminated the chamber for his new, yet to be named, documentary. “I was suddenly in absolute, complete black,” Fitz says. “The kind of darkness that we rarely experience.”

Geomedia: Books: Exploring "The Worst of Times"

Every reader of this magazine knows something about mass extinctions. But few of us know as much as Paul B. Wignall, a professor of paleoenvironments at the University of Leeds in England who studies mass extinctions. In 1997, he co-authored with Anthony Hallam a scholarly volume titled “Mass Extinctions and their Aftermath.” Now, his first book aimed at a popular audience, “The Worst of Times: How Life on Earth Survived Eighty Million Years of Extinctions,” has been issued in paperback.

Geomedia: Music: The sounds of the sea

At the ocean’s edge, the crash of waves against the shore is a familiar sound. It might be rhythmic, but it’s not particularly melodious. There are, however, a few spots around the world where the tides, waves and wind make actual music, thanks to acoustic man-made structures that use the movements of seawater to produce sound. Currently, three of these so-called tidal organs have been built, one each in Croatia, England and the United States.
