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 2 C or 8 C over the next hundred years? Will sea levels rise by 2 or 30 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...

Plants have colonized and modified the world's surface for the past 400 million years. In this book the authors demonstrate that an understanding of the role of vegetation in the terrestrial carbon cycle during this time can be gained by linking the key mechanistic elements of present day vegetation processes to models of the global climate during different geological eras. The resulting interactive simulations of climate and vegetation processes tie in with observable geological data supporting the validity of the authors' approach.

Plants have profoundly moulded the Earth's climate and the evolutionary trajectory of life. Far from being 'silent witnesses to the passage of time', plants are dynamic components of our world, shaping the environment throughout history as much as that environment has shaped them.

In The Emerald Planet, David Beerling puts plants centre stage, revealing the crucial role they have played in driving global changes in the environment, in recording hidden facets of Earth's history, and in helping us to predict its future. His account draws together evidence from fossil plants, from...
