Six Degrees: Our Future on a Hotter Planet
Did I say terminal illness? That's a bad metaphor, since disease seems sort of just to passively happen; also, we tend to think of illness as some ...more
This is, roughly, one part robust scientific journalism and one part ecological-apocalypse-torture-porn. Working from several decades worth of scientific inquiry into both our current climate situation and periods of vast geologic/climactic upheaval, Lynas gives us a best guess global picture of what happens as the temperature rises, degree by degree, from one (sucky) to six (extinction of most pl ...more
What Lynas has provided here is a comprehensive summary of international research on climate change and carbon emissions from a variety of perspectives and methodologies. The result is a harrowing projection of the kinds of shifts in ecosystems around the world - water tables, weather patterns, food production, biodiversity, ocean acidity - that are likely t ...more
Lynas poured over journal articles and research papers, and then decided to organize the information according to degrees of warming. So there's a chapter dedicated to causes and effects of the warming of one degree Celsius, and then a chapter a ...more
This is an superb book for anyone interested in global warming, which should include all who inhabit this planet. It paints a picture of what happens to the Earth at each step as it warms up by one additional degree Celsius, all the way up to six degrees above today's temperature. Needless to say, things get very ugly by the time we get to three degrees, let alone six. The latter translates to another mass extinction. Which, come to think of it, we're already going through.
This is not the cheeri ...more
Six Degrees summarises the likely consequences of global warming into a form that an interested layman like me can digest without being overwhelmed. The evidence that global warming is being driven by carbon dioxide from fossil fuels is straightforward and incontrovertible. I haven't doubted that since I first saw the famous 'hockey stick' graph, showing how global temperatures have been shooting up since t ...more

It lays out in detail what each degree of global warming will entail (the current expected range of warming is somewhere between 1.5 and now possibly up to 8 degrees Celsius), and how that will affect life on Earth. We are already locked into experiencing the first chapter, which is the likely return of the American Great Plains to desert. Each successive chapter just gets worse, and describes positive feedback systems which will make thin ...more
One point the author makes is that we simply don't know what to expect from all of this melting and heating up, things could rock and roll right away, a lo ...more
of the US will be starved of rain,
Bankrupted farmers will pack up and flee
as desert restakes its claim.
There'll be no ice cap on the Arctic,
we'll lose the rivers of Kilimanjaro,
and frost that keeps the Alps secure
won't do it any more.
The Barrier Reef will bleach and die,
mountain animals will reach the sky
chasing the cool, and those that can't fly
will join the dinosaurs.
Tropical storms expand their domain
to bludgeon new regions - Brazil, Spain -
and hope is lost f ...more
Lynas is not himself a climatologist, although he clearly knows the high places of the world and has had to struggle down off the Andes on the point of expiry after seeing for himself what is going on up there. As such, he has ...more
Lynas dedicates a chapter of his book to each of these degrees, describing the consequenc ...more
This is one of those books that stays with you long after you read it. Lynas bluntly tells us what happens with Earth after each degree of temperature that rises. I read the book a few years ago and still can remember how devastating the rising temperatures will affect life. Either in 2013 or 2014, Scientists have stated that the Earth’s temperature has risen by 1.something degrees already, and we’re seei ...more
Get out your wet weather gear, your fire-fighting pumps and your sunscreen. Times are changing. Also, methane plumes have just been found in the Arctic, each of them kilometers wide. Tipping points are kicking in. Damn all those stupid politicians and mining magnates like Gina Bloody Reinhart for being recalcitrant tossers, who really don't give a damn, unless they can get votes or make a quick buck.
This is an alarming book. Eight years later, with the global temperature increase at 0.7 degree Centigrade, the first chapter's predictions seem to be happening, especially the melting of glaciers and the Arctic ice. Apparently the damage to coral reefs by bleaching and human activities continues. Atlantic hurricane activity is not yet clearly stronger and fewer. But neither is it any weaker or more frequent.
I got what I asked for. The book accomplishes what it sets ...more

The book came "alive" towards the end. The chapter on the six degree scenario was necessarily different as very few models seem to ha ...more
The book describes what would happen to the Earth as the average surface temperature increases, degree by degree (Celsisus.) Each degree presents a new list of h ...more
Everyone should read this book. Why is this information not being yelled from the housetops and part of every politician's speech?
The scientists so far have done a poor job of explaining to the rest of us what climate change means. Al Gore's film The Inconvenient Truth also fell short. This aut ...more
Organised degree by degree, this book uses research from climate modelling and, more telling, what's happened in the past ...more
This book is an attempt to synthesise in a popular science format a load of academic studies and literatures about what will happen to the world if the temperature rises, degree by degree. The range, 1-6 degrees is in line with the IPCC's range of prediction.
The format is a bit problematic, to my mind, though I'm not sure how it could be done better. It's organised as a series of short essays on particular case studies - for example, wildlife in Australian rainforests, the Colorado river basin,...more
