In Storms of My Grandchildren, Dr. James Hansen, the world's leading scientist on climate issues, speaks out for the first time with the full truth about global warming- the planet is hurtling even more rapidly than previously acknowledged to a climatic point of no return. Although Hansen was Al Gore's science advisor for An Inconvenient Truth, his recent data shows that our situation is even more dire today. But politicians haven't made the connection between the policy and the science. He shows why Gore's solution won't work, why we must phase out all coal, and why 350 ppm of carbon is a goal we must achieve in the next two decades if our grandchildren are to avoid global meltdown. This urgent manifesto bucks conventional wisdom (including the Kyoto Protocol) and is sure to stir controversy, but Hansen - whose climate predictions have come to pass again and again, beginning in the 1980s when he first warned Congress about global warming - is the single most credible voice on the subject worldwide, and this book is sure to receive enormous attention. Hansen paints a devastating but all-too-realistic picture of what will happen in the next year, and ten years from now if we follow the course we're on. But he is also an optimist, showing that there is still time to do what we need to do. Urgent, strong action is needed, and this book, released just before the Copenhagen Conference in December 2009, will be key in setting the agenda going forward to create a groundswell, a tipping point, to save humanity - and our grandchildren - from a dire fate more imminent than we had supposed.… (més)

The two stars are a bit generous. This book was part description of the factors affecting climate change, part political mémoir, part publication and presentation history with some personal commentary. I found the actual science interesting (and worrisome), but the political digressions distracted from it. ( )

En overraskende personlig bog skrevet af NASA's klimaekspert James Hansen. Han er overrasket over hvor sårbar planetens klima er og over hvor hurtigt en opvarmning kan ske. Hvis vi brænder alt fossilt kul af, så ender vi som Venus nr 2 i solsystemet.
Han ser sig selv som et Vidne, ikke som en Prædikant. Han beskriver sine egne erfaringer fra 2001-2009 og starter med sin 60 års fødselsdag. Eller rettere helt fra start og med sin første videnskabelige artikel, nemlig en observation af en måneformørkelse i marts 1963, som kom ni måneder efter et stort vulkanudbrud på Mount Agung.
I 2001 kommer han med i en Climate Task Force nedsat af præsident Bush. Han forklarer fænomener som Den Sydlige Oscillation og Climate Forcings. Og tidligere klimaændringer, fx Den Lille Istid og forklarer blandt andet med et lille 1-watts juletræ. I sig selv ikke ret meget, men hvis der brænder sådan et ekstra juletræ på hver kvadratmeter af Jorden altid, så kan der ske ting og sager. Han har nedjusteret sin egen fornemmelse for hvor meget co2 der er for meget. 350 ppm højst, tak!
En enkelt grad nedkøling stoppede engelsk vindyrkning. Præsidentens Climate Task Force er en form for cherry picking, hvor man har udvalgt folk, der siger noget, man gerne vil høre og så nogle naive videnskabsfolk, der tror at det er en ærlig debat.
James Hansen vender tilbage fra det andet møde i Climate Task Force og sætter sine studerende på sagen.
I mellemtiden sørger Dick Cheney og Bush for at stoppe det her forsøg på at tage fakta-baserede beslutninger.
Og fysikerne begynder at regne på forsimplede klimamodeller, hvor man fx tager en uændret jord og fordobler co2 koncentrationen. Det giver 4 watt pr m2 i forcing og en simpel Planck-model giver at Jorden så bliver 1.2 grader celsius varmere. Klimamodeller er ikke ret meget bedre, for de skal modellere helt uhyggeligt meget.
Metan og sod skal i hvert fald også tælles med.

Resten af historien er lige sådan. Politikerne lytter ikke (med undtagelse af Al Gore). Eller er købt og betalt af kul og olie industrien. Et godt bud på hvor det ender er en isfri jord med en havstigning på 75 meter. ( )

James Hansen was a scientist at NASA with a particular interest in climate change. This book explains what is happening with climate change and what needs to be done to stop the potentially devastating effects.

I was listening to the audio, and I think that made it a bit tougher for the science. I am interested, but listening to it was probably more dry than reading it, I'd guess. I've read a lot about it, anyway, but there were plenty of things I didn't know, either. I really didn't know much (anything?) about nuclear power, so that was an interesting chapter to me. What I really liked about the book, though, was the politics. Hansen was an insider, so it was especially interesting to read about that aspect. And he did talk about it quite a bit in the book. There are charts included in the book: with the audio came a pdf that you could open if you wanted to refer to those charts (and he would mention it in the audio when he was talking about one of those charts included in the pdf), which I thought was a good idea. Overall, I'll rate it good. ( )

This is the most important book of our time. Please read and take action to stop climate change. ( )

We could leave the coal in the ground, but will we? If we don't we could trigger a run-away green-house effect. Hansen is an atmospheric scientist and makes a compelling argument that we must phase out coal and leave the oil shale and tar sands alone. ( )
