Overview

One of the most dynamic writers and one of the most respected scientists in the field of climate change offer the first concise guide to both the problems and the solutions of global warming. Guiding us past a blizzard of information and misinformation, Gabrielle Walker and Sir David King explain the science of warming, the most cutting-edge technological solutions from small to large, and the national and international politics that will affect our efforts.
While there have been many other books about the problem of global warming, none has addressed what we can and should do about it so clearly and persuasively, with no spin, no agenda, and no exaggeration. Neither Walker nor King is an activist or politician, and theirs is not a generic green call to arms. Instead they propose specific ideas to fix a very specific problem. Most important, they offer hope: This is a serious issue, perhaps the most serious that humanity has ever faced. But we can still do something about it. And they’ll show us how.

Editorial Reviews

Publishers Weekly

In this excellent primer on arguably the most serious problem facing the world today, Walker (An Ocean of Air) and King, the U.K.'s chief science adviser, present in concise layman's language "everything you wanted to know about global warming but were too depressed to ask." They explain how fossil fuels produce carbon dioxide, show how global warming is affecting individual species and changing entire ecosystems, predict how much more climate change we can afford before things become truly catastrophic, and consider economic and political solutions to the problem. They contend that we must rein in greenhouse gases in the next two decades if we want to leave a habitable planet for our grandchildren, and in order to do this, individuals must cut down on carbon emissions and at the same time pressure their governments to do the same by adopting low-carbon technologies such as geothermal, wind, solar and nuclear power. Entertaining as well as deadly serious, this lucid book, which includes an appendix that dispels many myths and misconceptions, explains in the clearest possible way why we should care about global warming and what we can do about it.

This is the best overview of global warming that this reviewer has read. New Scientist contributor and science writer Walker (An Ocean of Air) and King, the UK's chief science adviser, have written a readable and understandable guide to the science that proves the reality of global warming, analyzes how humans have contributed to this warming trend, and predicts how fast it will accelerate. Once the scope of the problem is accepted and understood, the next step is to decide how much warming we can live with; the authors present our options for setting limits and slowing down our contributions to this trend. They clearly explain the technological, governmental, and economic resources available to us globally. What is most valuable about this book is that the text clearly explains to lay readers a very complex and highly controversial topic. An appendix outlines climate myths, half-truths, and misconceptions about global warming. A glossary is included. An excellent and highly recommended addition to high school, public, and university library science collections.

Kirkus Reviews
An incisive look at global warming. Walker (An Ocean of Air: Why the Wind Blows and Other Mysteries of the Atmosphere, 2007, etc.), and King, director of research at the University of Cambridge, begin with the science that demonstrates the reality of global warming and its origin in human activity. The climate since the last decade of the 20th century is the hottest since record keeping began. Archaeological and paleontological evidence indicates that the Earth is currently warmer than it has been for at least 1,000 years. The reason is clear: The atmospheric concentration of carbon dioxide is the highest in 650,000 years. Because of this, we can expect more intense tropical storms; drought in middle latitudes (the United States, much of Europe and Asia); killing heat waves; rising sea levels; spread of infectious diseases; crop failures; migrations and warfare caused by climate change. Although warming can be expected to continue of its own momentum for some time, note the authors, we may be able to keep it to about 3.5 F° above pre-industrial levels. Suggesting means to rein it in, they stick to currently feasible tactics: finding alternatives to fossil fuels, conserving energy with better insulation and more efficient appliances, adopting more efficient forms of transportation, halting deforestation. While some steps, such as wider use of nuclear power, face much resistance, even hardcore environmentalists may decide the tradeoffs are worth the risks. The book's third section tackles what may be the most difficult task: conjuring the political will to do what is necessary. Resistance is high in developing nations such as China, and some developed nations-notably the United States andRussia-have been reluctant to face reality. Still, after the authors look closely at a dozen nations, they find reasons for optimism. Ordinary people can make a difference, they declare, if enough of us try. Practical, detailed and authoritative-essential reading. Agent: Michael Carlisle/InkWell Management

WARMING WORLD

Climate change isn’t new. Our planet is restless and its environment rarely stays still for long. There have been times in the distant past when carbon dioxide levels were much higher than they are today and Antarctica was a tropical paradise. There have been others when carbon dioxide levels were much lower and even the equator was encrusted with ice.

 

        But over the past ten thousand years, the time during which human civilization has existed, Earth’s climate has been unusually steady. We humans have become used to a world where the way things are is more or less the way they will be, at least when it comes to temperature. In other words, we have been lucky.

 

        Now our steady reliable climate is changing, and this time nature isn’t to blame. But how do we know for certain that the world is warming, and how can we identify the culprit?

 

The Heat Is On

When you’re trying to determine whether the world’s temperature is rising, the biggest problem is picking out a signal from the background “noise.” Even in our relatively stable times, temperatures lurch up and down from one day to another, from season to season, from year to year and from place to place. To be sure that the underlying trend is changing, you need to take precise measurements from many different places around the world, and do so for an extremely long time.

 

        We do have a few long temperature records, thanks to certain individuals who decided to make the measurements just in case they ever proved useful. The world’s longest is the Central England Temperature Record, which is a tribute to the obsessive data-collecting habits of seventeenth-century British natural scientists. It covers a triangular region of England from London to Bristol to Lancashire and stretches back to 1659. This impressive record shows clear signs of warming, especially toward the end of the twentieth century.

 

        However, the record covers only a tiny part of the globe. Changes in England don’t necessarily reflect changes in the United States, say, or Brazil. It also doesn’t go back far enough to reveal just how unusual our recent warm temperatures really are. How do they compare, for instance, to the apparent warm period in medieval times when the Vikings settled a verdant, pleasant “Greenland” and there were vineyards in northern England? Or to the so-called Little Ice Age in the midcenturies of the last millennium, when the River Thames in London froze over completely so that frost fairs were held on its solid surface?

 

        To answer these questions, scientists have come up with ingenious ways to expand the records geographically and extend them backward in time. Some people have tried to interpret written archives that didn’t quote actual temperatures,1 but the best way is to look at records written not by humans, but by nature.

 

        Every year, the average tree grows a ring of new wood around its trunk. In a good year the ring will be thicker, in a bad year, thinner.2 Researchers drill a small core into the side of the tree, about the diameter of a wine cork, extract the wood, and then count and measure. By examining trees that are different ages, and even some trees that are long dead but have been preserved in peaty bogs, they have come up with a temperature record spanning more than a thousand years and from regions across northern Europe, Russia, and North America.

 

        For more tropical regions, corals can play a similar role since they, like trees, grow a new ring every year. And in the frozen north and south (and the snowcapped peaks of tropical mountains), ice also contains a record book of past climate. Each year’s snowfall buries the previous one. If temperatures are cold enough, the snow stays around long enough to be squeezed into ice, clearly marking out the annual layers because summer’s snow crystals are larger than winter’s, or because more dust blows in each year with the winter winds. The amount of snow that fell in a given year, and especially the changing nature of the oxygen atoms bound up in the ice,3 gives clues as to how warm it was then.

 

        Another clue comes from changing plant life, as written into the record of mud at the bottom of lakes. As temperature rises and falls, different plants flourish and each one sheds its pollen into passing currents of air. Some of this lands on the surface of a nearby lake, before slowly sinking into the mud beneath. Drill a hole in this mud, collect and analyze the pollen grains each layer contains, and you have yet another record of temperature changes over time.

 

        Researchers have now used a host of different ways like these to analyze and splice together these different measures, and all come to strikingly similar conclusions for temperatures over the last thousand years.4 The eleventh century was indeed relatively warm, corresponding to the Medieval Warm Period. (“Verdant” Greenland turned out to be more of a marketing exercise than the truth. Ice cores drilled into the heart of Greenland’s ice cap show that a substantial quantity of ice has been present on the island for hundreds of thousands of years. Any Vikings who fell for the hype must have had an unpleasant shock when they arrived.)

 

        Temperatures were also cooler in the seventeenth century, corresponding to the Little Ice Age, and again in the early nineteenth century. These warm and cool periods apparently were also fairly widespread, though they may have been less prevalent in the southern hemisphere.5

 

        However, it was only in the twentieth century that temperatures really began to take off. The warming didn’t happen regularly, but in two bursts—which turns out to be important. The first one occurred during the early years of the century and was marked enough that it made itself clearly felt. In 1939 Time magazine wrote: “Gaffers who claim that winters were harder when they were boys are quite right?.?.?.?Weather men have no doubt that the world at least for the time being is growing warmer.”6 But the following few decades brought slightly cooler temperatures, at least in the northern hemisphere, and public interest waned.

 

        The second burst of warming began in the 1970s and has been gathering pace ever since. And, crucially, the temperatures we are experiencing now are hotter than they have been for the entire last millennium. Even the Medieval Warm Period was cooler than it is today.7

 

        Let’s look at some numbers. Globally averaged, from the 1910s to the 1940s temperatures rose by about 0.6°F. After that there was a cooling of about 0.2°F, and since 1970 the world has warmed by a further 1°F.8 These numbers might not sound like much, but they are very significant. Although the temperature where you live can change by much more than this within the space of a few hours or days, it is much more worrying when global annual averages show an inexorable upward trend. Averaging in this way smooths out short-term flurries and shows what’s really happening. That’s why a small change in global average temperature can reflect a very big shift in climate. Speaking in global averages, only a few degrees separate us from the frigid world of the last ice age.9

 

        Though the proxy records of tree rings, ice cores, and the like give a good indication of average temperatures over a time­scale of decades, they’re not as accurate on temperatures for individual years. Thus, although we can say that the temperature is now greater than it has been in the past thousand years, it’s harder to say how 2005 compared with, say, 1105. For that sort of pinpoint accuracy only a human record will do.

 

        Good widespread records started to become available by about 1850, so we can put the past few individual years into the perspective of the past 160 or so. Once again, the message is stark. The hottest years in the entire instrumental record were in 1998 and 2005. They were very close in temperature, and opinion is divided as to which one takes the warming crown. The years 2002, 2003, and 2004 were, respectively, the third, fourth, and fifth warmest on record. In fact, eleven of the past twelve years have been in the top twelve on record.10

 

        (Much fuss was made of the recent news that an adjustment to NASA’s records meant that one of the years of the Oklahoma Dust Bowl, 1934, was marginally warmer in the United States than 1998. While skeptics claimed that this threw the global warming research into disarray, in fact it did no such thing. These two years were long known to be within a few hundredths of a degree of each other in the record of local American temperatures. But averaged over the whole world, 1998 and 2005 remain the joint record holders. Regional records can be interesting, but they don’t tell the global story.)

 

        The Intergovernmental Panel on Climate Change (IPCC) is an international body made up of leading climate scientists and government advisers from around the world. In 2007 it was awarded the Nobel Peace Prize for its work on identifying the causes of global warming. Because its reports must reflect the consensus view of all its many contributors, the IPCC has a reputation for being conservative. It is also widely considered to be the definitive authority on the science of climate change.

 

        The latest report from the IPCC, published in 2007, describes the warming of the past few decades as “unequivocal.”11 There is no longer any room for doubt. The world is certainly heating up. What we need to know next is why.

    A reviewer

    This books is accurate with simple, down-to-earth explanations that anybody can understand, it is a 'fun' read and not overly technical, this book together with book by Lester Brown 'Plan B3 - Mobilizing to Save Civilization by Lester R Brown' should be read by government and business leaders around the world, we still have time to stop a catastrophe. Sadly, we human beings do not realize the extent of the problem, and continue living our lives with an attitude of 'business as usual', there are many people and animals that are being affected by climate change but they are the silent majority, we will only start addressing climate change once it affects countries in the west i.e weathlier nations that 'control the strings' Highly Recommended, a must read!!!
