A captivating, essential book to add to the necessarily burgeoning literature on global warming.




The past, present, and future of the ice clock on the world’s largest island.

Journalist Gertner (The Idea Factory: Bell Labs and the Great Age of American Innovation, 2013) made six trips to Greenland to research this penetrating and engrossing book. The Greenland ice sheet, two miles deep in some places, is “composed of nearly three quadrillion…tons of ice.” The author recounts the key 19th-century expeditions to explore the daunting, often harrowing, inner ice shelf. He is especially strong in his descriptions of the brutal cold, winds, ice floes, crevices, frostbite, lost toes, starvation, and loneliness that explorers have experienced over the decades. In 1888, Fridtjof Nansen and a small team dragged heavy sledges over ice peaks as high as houses to become the first to “cross Greenland’s ice sheet.” He was quickly followed by Robert Peary, the first to explore Greenland’s mysterious northern border, a 1,200-mile trek. Knud Rasmussen and Peter Freuchen’s explorations, which gathered valuable “ethnographic research on the Inuit,” marked the transition from merely exploration to scientific investigation. Alfred Wegener’s 1912 expedition “pushed the cause of Arctic science forward” and featured research on seasonal temperatures. One scientist presciently pondered that if all the ice melted, the oceans across the globe “would rise more than 25 feet.” Gertner next traces the many expeditions and scientific bases that were established and the use of deep drilling techniques to take sample ice cores all the way to bedrock. Scientists began to record temperatures gradually rising all over the island. Then, in 2012, using NASA’s satellites, a polar scientist made a frightening discovery: “We realized the entire surface of the Greenland ice sheet had melted.” Water was running to the sea, increasing the calving of glaciers in Greenland and the Arctic. Something “immense and catastrophic” had been set in motion and “could not be easily stopped.”

A captivating, essential book to add to the necessarily burgeoning literature on global warming.

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science...


Bryson (I'm a Stranger Here Myself, 1999, etc.), a man who knows how to track down an explanation and make it confess, asks the hard questions of science—e.g., how did things get to be the way they are?—and, when possible, provides answers.

As he once went about making English intelligible, Bryson now attempts the same with the great moments of science, both the ideas themselves and their genesis, to resounding success. Piqued by his own ignorance on these matters, he’s egged on even more so by the people who’ve figured out—or think they’ve figured out—such things as what is in the center of the Earth. So he goes exploring, in the library and in company with scientists at work today, to get a grip on a range of topics from subatomic particles to cosmology. The aim is to deliver reports on these subjects in terms anyone can understand, and for the most part, it works. The most difficult is the nonintuitive material—time as part of space, say, or proteins inventing themselves spontaneously, without direction—and the quantum leaps unusual minds have made: as J.B.S. Haldane once put it, “The universe is not only queerer than we suppose; it is queerer than we can suppose.” Mostly, though, Bryson renders clear the evolution of continental drift, atomic structure, singularity, the extinction of the dinosaur, and a mighty host of other subjects in self-contained chapters that can be taken at a bite, rather than read wholesale. He delivers the human-interest angle on the scientists, and he keeps the reader laughing and willing to forge ahead, even over their heads: the human body, for instance, harboring enough energy “to explode with the force of thirty very large hydrogen bombs, assuming you knew how to liberate it and really wished to make a point.”

Loads of good explaining, with reminders, time and again, of how much remains unknown, neatly putting the death of science into perspective.

Ackerman writes with a light but assured touch, her prose rich in fact but economical in delivering it. Fans of birds in all...


Science writer Ackerman (Ah-Choo!: The Uncommon Life of Your Common Cold, 2010, etc.) looks at the new science surrounding avian intelligence.

The takeaway: calling someone a birdbrain is a compliment. And in any event, as Ackerman observes early on, “intelligence is a slippery concept, even in our own species, tricky to define and tricky to measure.” Is a bird that uses a rock to break open a clamshell the mental equivalent of a tool-using primate? Perhaps that’s the wrong question, for birds are so unlike humans that “it’s difficult for us to fully appreciate their mental capabilities,” given that they’re really just small, feathered dinosaurs who inhabit a wholly different world from our once-arboreal and now terrestrial one. Crows and other corvids have gotten all the good publicity related to bird intelligence in recent years, but Ackerman, who does allow that some birds are brighter than others, points favorably to the much-despised pigeon as an animal that “can remember hundreds of different objects for long periods of time, discriminate between different painting styles, and figure out where it’s going, even when displaced from familiar territory by hundreds of miles.” Not bad for a critter best known for bespattering statues in public parks. Ackerman travels far afield to places such as Barbados and New Caledonia to study such matters as memory, communication, and decision-making, the last largely based on visual cues—though, as she notes, birds also draw ably on other senses, including smell, which in turn opens up insight onto “a weird evolutionary paradox that scientists have puzzled over for more than a decade”—a matter of the geometry of, yes, the bird brain.

Ackerman writes with a light but assured touch, her prose rich in fact but economical in delivering it. Fans of birds in all their diversity will want to read this one.
