Product Review
`Within these pages is one of the greatest stories ever told It is as fascinating as it is important.' New Scientist
`Here at last is David Beerling as the Green Knight, revealing the extraordinary story of the construction of our emerald planet. Rigorous science joins hands with an enthusiastic delivery to re-awaken our fascination in plants, while engaging anecdotes provide a thrilling background to an extraordinary story of climate change and our current environmental crisis. ' Simon Conway Morris (author of Life's Solution)
`Beerling gives us the big picture of how plants have changed our planet - and poses the key question of how we will manage the emerald planet to ensure the kind of future we desire. ' Sir Peter Crane (Director of the Royal Botanic Gardens, Kew, 1999-2006)
Product Description
Global warming is contentious and difficult to measure, even among the majority of scientists who agree that it is taking place. Will temperatures rise by 2oC or 8oC over the next hundred years? Will sea levels rise by 2 or thirty feet? The only way that we can accurately answer questions like
these is by looking into the distant past, for a comparison with the world long before the rise of mankind.
We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the
conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the
history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils.
David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of
climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.
Reader Reviews
For many years, as fossil plants emerged from the rocks, it was believed that these records reflected changes in climate. Plants, it was assumed, had to adapt to variations in weather and other conditions. According to Beerling, plant life was instead the major prompter of climate change. The balance of atmospheric gases was determined by the micro-organisms floating in the seas. The ability to absorb carbon dioxide, coupled with the use of sunlight to convert that into nutrients gives plants the power to shift gas quantities. During the early days, plants exhaled oxygen. It was poison to most organisms, but those capable of using it began the drive leading to today's life. In this useful survey of all the forces forming today's world, Beerling traces how plants "changed Earth's history". Following his thesis requires the reader's close attention, since the organisation of the material is necessarily loose - not fixed chronology nor subject. The many topics to cover cannot be neatly niched. To the author, the biggest mystery lies in the long delay between plants colonising the land and the formation of the first leaves. Leaf structure reflects how the plant is using energy. That, in turn, becomes a signal of how the atmosphere is composed at any given time. This knowledge was assembled over many years through the work of many researchers. Beerling traces the building of data resources and how the information was interpreted. Images of leaves and stems, analysis of the rock chemistry, field observations and laboratory experiments all contributed to the picture of plant evolution. Numerous surprises emerged, sometimes leading scholars to doubt the data and even their methodology. Looking at the life of plants down the ages is, as he puts it, looking "Through a glass darkly". Pervading his presentation is what the implications are for what is occurring in today's atmosphere - on which our life and those of our children, depends. Beerling deems investigations into ancient atmospheres a form of "breathalyser", such as the police apply to suspected impaired drivers. In this case, however, it's not alcohol fumes that are measured, but carbon dioxide. Other gases are also sought, but they don't often leave sufficient clues. The information must be derived indirectly. Again, it's the plant's leaves that are used as the pointers to how ancient atmospheres fluctuated. Underlying the variations is the mighty force of plate tectonics. The shifting of land masses and changes in surface configuration leads plants to shift their survival strategies. Acting far more rapidly than creeping continents, the ability of plants to accelerate or impair rock weathering shifts the presence of gas quantities. Carbon dioxide quantities have varied markedly, leading to most of the world's history being warm times. Only recently - in geologic terms - has the planet experienced a cool era, which led to the "ice age" that scoured the Northern Hemisphere with massive glaciers. As with so much in science, the revelation that plants drive climate instead of passively responding to it has produced at least as many questions as answers. There are anomalous circumstances that must be unravelled. The knowledge gained has led to the formation of "Earth system analysis" techniques using various forms of computer modelling. Many details, however, remain to be worked out. Atmostpheric studies are particularly impaired by lack of knowledge of cloud formation and distribution. Carbon itself, both as a greenhouse gas and as a component of plant growth, remains enigmatic. Beerling traces the selectivity of plants in choosing which carbon isotope will be utilised. That choice has impact on which plants will become dominant in a given area, which also has implications for the animal life living from them. There are no simple nor ready answers to what plants have meant in tracing life's development. Yet, as he emphasises frequently, these are questions that must be addressed further, and that, soon. Understanding our atmosphere is essential to our future. [stephen a. haines - Ottawa, Canada]
