The Chilling Stars: A New Theory of Climate Change
The authors explain their theory that sub-atomic particles from exploded stars have more effect on the climate than manmade CO2. Their conclusion stems from Svensmark's research which has shown the previously unsuspected role that cosmic rays play in creating clouds. During the last 100 years cosmic rays became scarcer because unusually vigorous action by the Sun batted away many of them. Fewer cosmic rays meant fewer clouds―and a warmer world. The theory, simply put here but explained in fascinating detail, emerges at a time of intense public and political concern about climate change. Motivated only by their concern that science must be trustworthy, Svensmark and Calder invite their readers to put aside their preconceptions about manmade global warming and look afresh at the role of Nature in this hottest of world issues.

A fascinating explanation of scientific research into an alternative hypothesis of contemporary climate change. Briefly, the theory is that (1) cloud nucleation is promoted by cosmic rays (charged atoms ejected from exploding stars at relativistic speeds) that hit the Earth's atmosphere; and (2) the volume of those particles that hit the Earth varies with the long-term path of the Sun through the Milky Way and with the strength of short-term variations in the Sun's magnetic field, which helps shield Earth from the particles. Apart from explaining this intriguing theory and the (not-totally convincing) evidence for it, the book also provides interesting insight into astronomy, climate history, and the role that clouds play in driving climate.
That said, the book is weak in explaining why the cosmic-ray warming theory is more correct than the greenhouse warming theory, or why they can't both be true. Seems to me the effects should be additive. And yes, it is concerning that climate-change deniers will latch onto this science as somehow justifying a do-nothing stance. There is no one more dangerous than a man who has read only one book. (I'm looking at you, Sen. Inhofe.)

Svenmark's book for laymen on his research into the role of solar flares and cosmic rays on cloud formation----and ultimately on climate change. Important information for those interested in understanding the full scope of the scientific controversy over global warming.

A fascinating and worthwhile read for anyone who isn't entirely satisfied with the current understanding of climate change. However, it may have been useful to include more information/references about existing data...
In essence, the premise is that the amount of cosmic rays has a direct effect on cloud formation...more clouds, more cooling. The clouds closest to the earth's surface reflect sunlight. It presents a CERN project: CLOUD: Cosmics Leaving Outdoor Droplets which is designed to evaluate the effects of cosmic rays on cloud formation. This has received far less focus than the projects correlated with the Large Hadron Collider (LHC). I was intrigued to learn of this model.
Although very inconclusive, it also examines the snowball earth periods and provides an alternative possibility for what caused these dramatic climate changes which still remain a point of contention.

Another piece of the puzzle snaps into place! Actually, I was inclined to be very skeptical of this hypothesis, but the authors have made a good case (lower solar activity => more primary cosmic rays => more low clouds (due to nucleation) => more reflected sunlight => lower global temps).
Prior to this book, my money was on oceanic circulation as the primary forcing function of climate change (After all, the oceans contain 1000x the heat energy and 500x the CO2 compared to the atmosphere.)
We'll all be laughing at inadequacy of the CO2 climate change hypothesis in 20 years (that is, if the economic collapse due to cap-and-trade and its ilk doesn't turn humanity into a hunter-gatherer society).

Of the climate change books that I have come across, I feel most comfortable with this one. I had no idea that Stradivarius violins were made during a significant climate period called the Maunder minimum. I wonder whether this may bring some clarity to environmental sustainability issues and associated topics?

The book describes the theories and research of Henrik Svensmark and puts some context around the history of climate, climate research and the socio-political issues.
His research provides an alternative forcing factor to explain climatic variations (over multiple timeframes). Cloud creation is influenced by the Number of galactic cosmic rays hitting the lower atmosphere causing a coalescing event around ionized molecules. The stream of GCR's is regulated by the sun's (and to a certain degree by the earth's) Magnetic field, and the creation of high energy cosmic rays is the result of supernovae, among other things.
The best parts of the book were those describing Svensmark's background and story, and the methods used in climate research.
As you read about Svensmark you can't help but wonder if he will go down as one of the greats, assuming the research continues it's success. He is the humble leader that builds a following through pure respect for his creativity, grit and intellect. It's impressive how much he and his colleagues have achieved given the opposition they face.
The ending chapters were less interesting because it became a defense and call to action for Cosmoclimatology. The tone of the author in general felt very defensive and at times frantic. It's understandable given the current zeitgeist but not pleasant to read at times. In a way, it's a shame because Svensmark is always cool and collected in any interview I've seen.
For anyone not familiar with Svensmark I recommend reading this and/or watch the cloud mystery documentary.

"When the Sun is active, its magnetic field is better at shielding us against the cosmic rays coming from outer space, before they reach our planet. By regulating the Earth’s cloud cover, the Sun can turn the temperature up and down. ... As the Sun’s magnetism doubled in strength during the 20th century, this natural mechanism may be responsible for a large part of global warming seen then." (Henrik Svensmark)
So the argument here is that cosmic rays seed clouds, which cools the earth down. Unusually vigorous solar activity the past century has kept cosmic ray from cooling the earth. Svensmark stated in 2007 that scientist should 'enjoy warming while it lasts' and predicted a slight cooling every year until 2030, then a larger cooling of the planet after that. Well, galactic cosmic rays have increased every year since 2007 as measured by many observatories across the world, and temperatures have gone up every year since then. Also, it is scientifically irresponsible to put such faith in preliminary findings, the verification by other scientists does not back up these findings.

This is a science book. It is much more a science story than attempting to teach the science to the reader. IMO its a compelling story and it (on the surface) appears much more credible than the CO2 greenhouse BS propagated by the IPCC for decades now. They have the ice cores with isotopic analysis correlating cosmic ray flux with colder temperatures. Cosmic rays interact with N to form C14 and isotopes of Boron. And, cosmic rays are proven conclusively to create cloud cover in the lower atmosphere which we know leads to lower temperatures. The book then moves to sources of cosmic rays (supernova and galactic midplane crossing) and also modulation of cosmic rays blocked by our Sun and the local bubble. I'd love to read more about our local star group BTW.

brilliant authors, mostly about clouds and cosmic rays, ideal for climatologist
very misleading title, in 2007 authors firmly had no conclusion on climate change either way. What's interesting it much of this underlying research here has been developed to help the broader scientific community understand why global warming is happening beyond reasons of fossil fuels and green house gasses.
Well written, but dangerous because of both the title and confirmation bias. This is foundation material for new discoveries TODAY in 2020. Book was from 2007, with research accumulated since the 90's. Important, but science is always evolving.

'Before you make up your mind about climate change you are advised to read this controversial, compelling book' Nexus
Scientists agree that the earth has become hotter over the last century. But on the causes, despite what looks to the public mind like a consensus, there are dissenting voices.
Based on Henrik Svensmarks research at the Danish National Space Center, this book outlines a brilliant and daring new theory that has already provoked fresh thinking on global warming. As prize-winning science writer Nigel Calder and Svensmark himself explain, an interplay of the sun and cosmic rays sub-atomic particles from exploded stars seem to have more effect on the climate than man-made carbon dioxide.
For anyone interested in the real science behind our climate, this book is a must-read.

Incredible book. It shows how an active sun blocks cosmic rays, how cosmic rays help create more low level clouds, and how low level clouds cool the Earth. Active sun = less clouds = warming. Quiet sun = more clouds = cooling. He details how cosmic rays are measured across time by findings on Earth and how Earths changing climate coorelates to the amount of cosmic rays. He details how exploding stars, the Earths position in the galaxy, the Earth's position relative to the disk of the galaxy, and solar cycles all relate to historical climactic changes on Earth.
I Highly recommend this book.

Second Author Nigel Calder. An interesting look at the climate change debate which looks at the effect of the suns cosmic radiation and its effect on cloud cover. The authors argue that the effect of cloud cover could be very significant on the climate. This book questions some of the assumptions about climate change and could be seen as harmful to the current accepted wisdom. Well worth the read.

I get that it can be tough to be part of a dissenting minority in academia, but I think these guys crossed the line into pseudoscience by sensationalizing and exaggerating the meaning and value of what were only preliminary experimental results. This lacked the scientific rigour to be called a "theory". At best it was an untested hypothesis that demanded further investigation because of its potential implications for climate science and environmental policy-making.

Builds a very compelling case for how the sun's magnetosphere and its cycles has profound impact on the Earth's climate. It takes a look at the larger issue of how galactic events have had a huge impact on Earth's climate in the distant past.
Five stars for the facts contained within but 4 stars overall for less-than-topnotch science writing.

Oh Al Gore, does though lament thy fate? Read this book and tell me why Global Warming is 'definitely' caused by man?!?!
Though this of course does not make the case definitive and by no means am I saying I agree . . . just doubt and skepticism work wonders.

This hypothesis about global warming is intriguing, however they need much more data to substantiate it.

It is a science book so it isn't light reading, but it was interesting and very informative. I'd recommend it if you are interested in global warming theories, or in astronomy phenomena.
