Denialism invites devastation on a scale last seen during the Permian-Triassic (P-Tr) extinction event, and business or politics as usual will impose surrogate suicide on our children and grandchildren. Degree by degree "Six Degrees" explains the mechanisms behind global warming and the direct consequences of our actions (or inactions). From sophisticated and increasingly refined computer models, to the latest geological and paleontological evidence, Lynas compellingly argues that anthropomorphic climate change is a new and unprecedented challenge verging on calamity, not a routine and recurrent phenomenon due to cyclical natural causes.
From bleached and dying tropical coral reefs to polar bears that will melt into history along with the glaciers and ice flows they called home, the future is dire unless immediate, but achievable steps are taken. Some species may survive by migrating, but most will have nowhere to migrate to. Small changes result in sizeable impacts - a mere 3° C increase will turn the American Midwest, the world's breadbasket, and the Amazon Basin which supplies 20% of earth's fresh water, into arid wasteland.Read more ›
I was torn between assigning this book four stars or five. While there's nothing about this book I don't like, I didn't want to be influenced by my own conviction of the overriding importance of this topic for all of us, and have tried to grade the book purely on the basis of my reaction to it as a book.
But the topic is urgent and important, and Mark Lynas has treated it effectively and with authority. His approach was to review all the published scientific literature he could find on climate modeling and paleoclimatology. His sources therefore consist exclusively of peer-reviewed scientific papers: no pop-science books, interviews, or mass-market magazine articles. He created a database of articles and organized them into categories according to the amount of warming they discussed: 1 degree Celsius, 2 degrees Celsius, and so on up to 6 degrees.
The book builds up a picture of the heating Earth, each chapter notching the average temperature one degree higher. At 1 degree, for example, Lynas discusses the likely desertification of the American West. The great plains ranging east of the Rockies north to Saskatchewan are actually an ancient dune-field covered with a thin layer of soil held in place by plants. Climate models show its likely reversion to a more drought-stricken regime that has also existed in the ancient past. The result will be the death of the plants, and blowing away of the topsoil--just as happened with the Dust Bowl in Oklahoma in the 1930s. This new Dust Bowl will be much larger and more enduring--and where will all the people go?Read more ›
The disappearance of arctic summer ice, the eventual flooding of coastal communities from sea level rise, the prospects of widespread droughts including the western USA, are all exptremely disturbing ideas held by a majority of climatologists.
This is a good summary of where we are with climate science right now, as Lynas bases his book on up to date searching of the science literature. The only outdated thing I could find was his failure to mention the political defeat of the Howard government in Australia partly due to public concern there about drought caused by climate change. Climate science has advanced greatly in the past few years, so do not base your views on something five years old!
My only criticism of this book is that the structure Lynas imposes is barely able to handle the massive amount of material. But I still rate it a firm four stars because of the timeliness and breadth of coverage. Too many of us are ill informed on this topic in an election year that may determine our approach to the problem for the next eight years. Too many of us fail to accept the basic concept explored by Lynas- that climate change is cumulative. Too many of us murmur smugly that we are not going to devote any energy or money to a problem that will kick in mostly after we die of old age.
Do you plan to have grandkids? I do. Read this.
