On Thin Ice: The Changing World of the Polar Bear (Vintage) ReviewEllis, a writer, artist, and conservationist mainly known for his work on matters maritime, here turns his attention to Ursus maritimus. The polar bear is the largest modern land predator, albeit one that spends significant time in the water and depends on the marine food web.
The book is, not surprisingly, a very good one. It has Ellis' trademarks of thorough research (there is a typical Ellis bibliography, running 26 pages) and good writing. My favorite turn of phrase comes when, after reviewing how all sorts of polar bear parts are used for decoration and so on following legal hunts in Greenland, the author remarks, "In other words, nothing is wasted except the bear."
This book is a superb introduction to the polar bear, its world, and its interaction with humans. I had a pretty good idea from other reading how remarkable this animal and its adaptations are, but a lot of the bear-human history surprised me. For example, I had no idea anyone had, or could, or would want to, train a polar bear team to pull a sled.
The most surprising thing for me, though, was how numerous the animals must have been centuries ago. Early European explorers didn't just see the occasional bear: they saw dozens, or, over a season, sometimes hundreds. I asked Richard if anyone knew the species' population before Europeans entered its realm. It may have approached twice today's estimate of around 22,000, but he cautioned there was no reliable number. All that's certain is that hunting and indiscriminate killing removed many thousands.
Ellis seems to have read every account by explorers, whalers, and everyone else who ever saw a polar bear. The bear's behavior is explored in depth, and some myths rejected. An excellent chapter explores why humans are so darn fascinated with the polar bear, along with the contradiction between our love for the adorable cubs vs. our historic willingness to kill adults even when there is no need to.
Then we get to the threatened status of the bear today. The species still numbers many thousands, and is not actually going to disappear anytime soon. However, there is no question that, as Ellis documents, climate change will affect polar bears more quickly and more severely than it will most species.
A side note is that, in an unaired portion of a 2008 interview I did for the series MonsterQuest, I hypothesized that declining ice to the north and more human development to the south would push brown bear and polar populations together, resulting in more "pizzly" hybrids. I tossed that off the top of my head at the time: I didn't realize that, as Ellis shows, more qualified people have advanced the same idea. A hybrid shot in 2006 is the first proven example of a cross occurring in the wild, but it likely won't be the last.
When Ellis discusses climate change, the reader gets the impression that it's a simple case of sometimes-hyperbolic but pure-hearted environmentalists vs. totally evil corporations and Republicans. I'm not about to defend the Bush environmental record, but there are debates about everything from the conflicting estimates of warming to the tradeoffs (never mentioned here) in outlawing oil and gas development in northern regions, and Ellis could have acknowledged that these subjects are complex even as he makes a persuasive case for action.
Summary: If the polar bear has an official biographer, it is Ellis. It's the same role Ellis played in his outstanding books about the great white shark and the giant squid. The result is a tome everyone with an interest in nature, bears, or the environment should read.

Field Notes from a Catastrophe: Man, Nature, and Climate Change Review
One never ceases to marvel at the consistent way in which we humans seem to be lunging headlong into the ecological abyss. In this wonderful new book by former New York Times reporter Elizabeth Kolbert, the reader is whisked away into a series of field trips into the myriad of places across the globe where the increasing evidence of approaching disaster is being observed, discussed, and reacted to in ways that has to give the reader pause. Eskimos are abandoning a small island in the Artic Ocean even as the surrounding ice cap that once protected from wind and storm damage melts into oblivion as a direct result of the Greenhouse Effect.
Kolbert offer us poignant glimpses at humans forced to confront ugly truths about the nature of the Anthropocene era, that is, that so-far limited expanse of time that humans have inhabited the earth. Presented with the bulk of the evidence, it is hard for an objective intellect to escape the distinct possibility that as a species we seem to be hell-bent on self-destruction. Indeed, the breadth and scope of the manifest effects of climate change on human habitation is breath-taking, affecting societies as far-flung as Netherlands to Siberia, from South Africa to the Great Barrier Reef. She writes wryly about stepping through the looking glass in a conversation with a Washington wonk who attempted to justify the Bush administration's active opposition to both the Kyoto Treaty and any attempt to rework it into a manageable tool to effectively combat the effects of global warming.
It is in such encounters that she discovers her voice and her poignant sense of urgency; if the best educated among us choose to stand in active opposition, what chance is thereto turn this catastrophic change in climate around? Furthermore, in interviewing climate specialists, we discover that the environment is moving rapidly toward disaster, and while there are reasons to hope, there is also reason to view our inaction and our opposition to meaningful global action with alarm. As the former Third World countries like India and China become both more industrial and more consumptive societies, the environment's ability to overcome the cumulative injuries to the earth's biosphere becomes even more difficult to imagine. This book is an easy read, is quite informative, delivered in a reporter's style of succinct and yet comprehensive prose. It does yeoman's service in informing citizens of just how dangerous and calamitous this developing ecological, social, and economic catastrophe truly is. This is a great book, and one I can heartily recommend. Enjoy!
