An excellent well written visual book, 26 Apr 2002
This book makes you feel like hopping on the next plane to Alaska. The photographs are excellent and very colourful, which is a treat in itself. The essay is very informative and just right too, not too short and not too long. It is a book that you feel you want to pick up and read time and time again. Can we have another one written please!

geophysics!!!, 18 Jan 2004
This is the book all those who have nightmare of the mathematical aspects of geophysics need to see. This book simplifies all the calculus and makes it look like everyday arithmetic.Integrations are made to look like buying and selling, reading through the text gives you the feeling of reading a best selling novel. Earth scientists who care more about applications and not exotic principles and equation with theories will find this book an invaluable guide in everyday field and classroom work.The principles of the various geophysical methods are presented in basic understandable terms.Applications are stressed and practical examples given. Beginners, non geophysicist will get endeared to the course by merely reading through its first few flowing chapters. This all makes the subject look like a piece of cake, but that is what it is in reality following the way the whole subject is presented and outlined. i am a living testimony of how the book has fueled my interest and taken away my fear of all the numerous integrals and differential involved in geophysical theories. This is a must for all aspiring geophysicist as well those who want to know how the stuff works in geophysics. go get the book

Seems somewhat dated in 2001. Hard to read., 22 Nov 2001
This is one book given in a long preparatory reading list provided by the Open University for a course on "The Earth's Interior".
This is the 5th of the list which I have read. It has been the least readable. It muddles cause and effect. It jumps between sections of a subject without good signposting. It states categorically that full information can be found about a subject in a twenty-year-old paper. It often makes annoying statements that the research results affect geological processes, when it should say that the research affects the interpretation of geological processes.
There are a few topics in this book in which the explanations are better than in other books of similar topics.
It has been a most disappointing read, when I had expected that it would have been much more enlightening and clearer.
It is described as a "second edition", but is not as up-to-date as would be expected for a subject area in which there has been so much recent progress.

The end of the world? Not if, but when., 09 May 2008
This book is very nice: well written and concise - ideal for the beginner who wants a broad coverage of a fascinating topic. This is certainly one of the better 'short introductions' on the market.

The introductory chapter serves as a good overview for the rest of the book, while the proceeding chapters about global warming and the possibility of an ice age are both good. The text is fact-heavy but still flows nicely, telling a clear story. While the authors own views are certainly evident, he also mentions the ideas of other scientists (some contraversial and some downright mad).

The book goes on to discuss the threat and possible consequences of geological events such as super-volcanic eruptions, mega-tsunami's and city-destroying earthquakes. He not only considers the Earth sceince behind these phenomena, but the economic impact is also covered, albeit superficially. I found the chapter about the 'Threat from Space' particularly interesting (and disturbing).

I give the book 4 stars and not 5 because, i my opinion, it lacked scientific depth. I believe, even in a book so small and introductory, that the author could have given a little more explanation of the science. Perhpas he neglected to do this in the fear of scaring off potential readers who don't want too much of an intellectual challenge, or perhaps he was concerned with making the book too long for the format of the series (though he does repeat himself several times, so cutting down the words would not have been too difficult). A bit more technical science would have been welcome.

Overall, a very nice read with a pessimistic (but probably realistic) outlook.

Concise, hard-hitting and compelling - a brilliant introduction, 03 Apr 2008
The Very Short Introduction series by Oxford University Press has a good reputation for presenting challenging subjects in an easily accessible manner. "Global Catastrophes" by Bill McGuire is one of its very best examples. Originally published in 2002 as "A Guide to the End of the World", it has since been updated to include events as recent as 2005, with a new preface as well as a fully revised text and bibliography.

The book deals exclusively with environmental phenomena rather than man-made, technological disasters. In each chapter McGuire explores the evidence for - as well as the likely effects of - different catastrophes that could, in the near future, put an end to human civilisation, namely global warming, a new ice age, supervolanoes and other tectonic hazards, and lastly asteroidal impact. His mastery of the material is clear, and at every stage he is careful to back up his arguments with facts and figures drawn from scientific studies and computer models. At the same time his style is conversational and makes on the whole for easy reading, although occasionally the analogies he chooses tend to confuse rather than illuminate.

The opening chapter on global warming is the book's tour de force - as well as probably the most relevant for the reader today - providing a succinct summary of the main issues and sources of contention. McGuire pulls no punches, making it clear just how unprecedented is the effect that human industrial activity is having on the global climate, and how our planet is hotter now than it has been for 90% of its history. For any sceptics of climate change, or of its future implications for our civilisation, this will be a potent wake-up call. In complete contrast, the next chapter explores the counter-intuitive (yet nevertheless scientifically plausible) theory that rising global temperatures could in fact trigger a rapid freeze and a return to Ice Age conditions. But regardless of whether we are set for global warming or global cooling, McGuire demonstrates why this is an especially bad period in geological time for us to be experimenting with our atmosphere and climate.

The third chapter - on supervolcanoes and other tectonic events - is similarly well-argued, as one might expect from a Professor of Vulcanology at University College London. One disappointment, however, is the short treatment afforded to the topic of flood basalt eruptions, in particular the Deccan Trap event, which is now thought to have been a contributing factor in the decline and extinction of the dinosaurs. A significant amount of research is now being conducted into these events, which could have been explored further. Finally, McGuire's discussion of potential extinction-level asteroidal impact is both balanced and considered, stressing the catastrophic effect this would have while also underlining the unlikelihood of such an event occurring in the near future.

The book includes 20 images and diagrams, serving to illustrate and reinforce McGuire's points, as well as 2 appendices, summarising the relative frequency of the various threats and plotting the most significant on a geological timescale. The bibliography is thorough, divided according to the relevant chapters, and runs to no less than 65 titles, making this book an excellent platform for exploring the subject further.

All in all, "Global Catastrophes: A Very Short Introduction" is an excellent overview of what is a difficult, unsettling and sometimes contentious subject, and a book that I can highly recommend.

Don't Have Nightmares..., 04 Jul 2006
I've always been a bit of a fan of these Very Short Introductions - as someone who likes to be a know-it-all but has an increasingly short attention span they're perfect. Well this is one of the best I've read - highly informative, readable, packed with facts. A different version of the end of the world is contemplated on almost every page - and by placing the human race in its true timescale, as a negligible speck on the history of the planet, this is guaranteed to make you feel very small indeed. McGuire makes it clear that with most of the catastrophes he discusses, from the obvious global warming to the alarming super-volcanoes, it's a question of when, not if. And he dispenses with the hubristic notion that there's much we can do about it except prepare for the aftermath.

Frankly, makes me want to become an astronaut.

Forget Earth in upheaval; this is geology itself in upheaval, 04 Sep 2001
Those who have recalled Dr. Gold's work for NASA and his controversial pursuit of 'deep black goo' in oil drill samples from Sweden will be delighted to read of the full story here. An audacious synthesis of facts into a revised world-view of the science of geology as stunning in its' implications as continental drift theory was in the last century. Anecdotes from classical historians such as Seneca are interwoven with compelling data on the influx of carbonaceous materials from space during the formation of the Earth. Briefly, the Earth we live on is neither so stable nor so homogenous as those raised on the color geology books have been led to believe. The interior heat of the Earth has distilled the organics into the coal, oil and gas deposits we use today--if true, implying a stunning abundance of fuels beneath our feet, literally 4% of the volume of the oceans themselves, according to one estimate. The economic implications of this work alone make it worth reading.

This is the book all those who have nightmare of the mathematical aspects of geophysics need to see. This book simplifies all the calculus and makes it look like everyday arithmetic.Integrations are made to look like buying and selling, reading through the text gives you the feeling of reading a best selling novel. Earth scientists who care more about applications and not exotic principles and equation with theories will find this book an invaluable guide in everyday field and classroom work.The principles of the various geophysical methods are presented in basic understandable terms.Applications are stressed and practical examples given. Beginners, non geophysicist will get endeared to the course by merely reading through its first few flowing chapters. This all makes the subject look like a piece of cake, but that is what it is in reality following the way the whole subject is presented and outlined. i am a living testimony of how the book has fueled my interest and taken away my fear of all the numerous integrals and differential involved in geophysical theories. This is a must for all aspiring geophysicist as well those who want to know how the stuff works in geophysics. go get the book

I found the chapter about the 'Threat from Space' particularly interesting (and disturbing).

I give the book 4 stars and not 5 because, i my opinion, it lacked scientific depth. I believe, even in a book so small and introductory, that the author could have given a little more explanation of the science. Perhpas he neglected to do this in the fear of scaring off potential readers who don't want too much of an intellectual challenge, or perhaps he was concerned with making the book too long for the format of the series (though he does repeat himself several times, so cutting down the words would not have been too difficult). A bit more technical science would have been welcome.

Overall, a very nice read with a pessimistic (but probably realistic) outlook.

Concise, hard-hitting and compelling - a brilliant introduction, 03 Apr 2008
The Very Short Introduction series by Oxford University Press has a good reputation for presenting challenging subjects in an easily accessible manner. "Global Catastrophes" by Bill McGuire is one of its very best examples. Originally published in 2002 as "A Guide to the End of the World", it has since been updated to include events as recent as 2005, with a new preface as well as a fully revised text and bibliography.

The book deals exclusively with environmental phenomena rather than man-made, technological disasters. In each chapter McGuire explores the evidence for - as well as the likely effects of - different catastrophes that could, in the near future, put an end to human civilisation, namely global warming, a new ice age, supervolanoes and other tectonic hazards, and lastly asteroidal impact. His mastery of the material is clear, and at every stage he is careful to back up his arguments with facts and figures drawn from scientific studies and computer models. At the same time his style is conversational and makes on the whole for easy reading, although occasionally the analogies he chooses tend to confuse rather than illuminate.

The opening chapter on global warming is the book's tour de force - as well as probably the most relevant for the reader today - providing a succinct summary of the main issues and sources of contention. McGuire pulls no punches, making it clear just how unprecedented is the effect that human industrial activity is having on the global climate, and how our planet is hotter now than it has been for 90% of its history. For any sceptics of climate change, or of its future implications for our civilisation, this will be a potent wake-up call. In complete contrast, the next chapter explores the counter-intuitive (yet nevertheless scientifically plausible) theory that rising global temperatures could in fact trigger a rapid freeze and a return to Ice Age conditions. But regardless of whether we are set for global warming or global cooling, McGuire demonstrates why this is an especially bad period in geological time for us to be experimenting with our atmosphere and climate.

The third chapter - on supervolcanoes and other tectonic events - is similarly well-argued, as one might expect from a Professor of Vulcanology at University College London. One disappointment, however, is the short treatment afforded to the topic of flood basalt eruptions, in particular the Deccan Trap event, which is now thought to have been a contributing factor in the decline and extinction of the dinosaurs. A significant amount of research is now being conducted into these events, which could have been explored further. Finally, McGuire's discussion of potential extinction-level asteroidal impact is both balanced and considered, stressing the catastrophic effect this would have while also underlining the unlikelihood of such an event occurring in the near future.

The book includes 20 images and diagrams, serving to illustrate and reinforce McGuire's points, as well as 2 appendices, summarising the relative frequency of the various threats and plotting the most significant on a geological timescale. The bibliography is thorough, divided according to the relevant chapters, and runs to no less than 65 titles, making this book an excellent platform for exploring the subject further.

All in all, "Global Catastrophes: A Very Short Introduction" is an excellent overview of what is a difficult, unsettling and sometimes contentious subject, and a book that I can highly recommend.

Don't Have Nightmares..., 04 Jul 2006
I've always been a bit of a fan of these Very Short Introductions - as someone who likes to be a know-it-all but has an increasingly short attention span they're perfect. Well this is one of the best I've read - highly informative, readable, packed with facts. A different version of the end of the world is contemplated on almost every page - and by placing the human race in its true timescale, as a negligible speck on the history of the planet, this is guaranteed to make you feel very small indeed. McGuire makes it clear that with most of the catastrophes he discusses, from the obvious global warming to the alarming super-volcanoes, it's a question of when, not if. And he dispenses with the hubristic notion that there's much we can do about it except prepare for the aftermath.

Frankly, makes me want to become an astronaut.

Forget Earth in upheaval; this is geology itself in upheaval, 04 Sep 2001
Those who have recalled Dr. Gold's work for NASA and his controversial pursuit of 'deep black goo' in oil drill samples from Sweden will be delighted to read of the full story here. An audacious synthesis of facts into a revised world-view of the science of geology as stunning in its' implications as continental drift theory was in the last century. Anecdotes from classical historians such as Seneca are interwoven with compelling data on the influx of carbonaceous materials from space during the formation of the Earth. Briefly, the Earth we live on is neither so stable nor so homogenous as those raised on the color geology books have been led to believe. The interior heat of the Earth has distilled the organics into the coal, oil and gas deposits we use today--if true, implying a stunning abundance of fuels beneath our feet, literally 4% of the volume of the oceans themselves, according to one estimate. The economic implications of this work alone make it worth reading.

EXCELLENT - comprihensive and clear intro. to physical geog., 27 Feb 2001
Lovely images that clarify explanations and key points. Up-to-date and thorough case studies. The BEST book of its kind on the market....I use it for my degree and wouldn't be without it!!
