To be honest, I don't know if I should laugh, or cry at this book. I really don't. While I think about it, let me say that you should always give credit where credit is due, and the thing is, Gregory Wrightstone is a clever writer, because you have to be clever to do what he does to the facts and data in this book. He does it so well that I wouldn't blame anyone for falling for the claims presented in it.
He begins by claiming that water vapor is a greenhouse gas. Do you know what? He's is right. The fact is that water vapor really is a greenhouse gas, but there is nothing inconvenient about that fact. It's just a fact. You know, I have read and listened to quite a few climate scientists, and I have so far never heard any reputable member of that group ever refute this. The problem is that the science is a little bit more complicated than Wrightstone states. Both water vapor and CO2 are greenhouse gasses that raise temperature, but they play different roles in all of this, and they behave differently in the atmosphere. You see, the hotter is gets, the more water evaporates, which causes more water vapor. It is a cycle that means that if CO2 raises the temperature by one degree, the added water vapor will raise the temperature additional two degrees. So yes, water vapor raises the temperature more than CO2, but it wouldn't be raising the temperature without the temperature rises that CO2 caused.
Now Wrightstone is a clever writer like I already said. He knows someone will point out this very fact, so he counters it by saying that the water vapor feedback loop has been overestimated. The thing is, he never actually presents any evidence for his statement. Statement without evidence is an opinion, not a fact. And this is actually what Wrightstone does over and over throughout this book. He takes facts, jumps to conclusions with them, cherry picks the data he presents, and so on and on.
Let's look at another example, his claim that CO2 is plant food. Do you know what? He is right. He is absolutely right. CO2 is plant food. The thing is, just as it was with water vapor, that is not an inconvenient fact. It is not a contested fact. It is just a fact. But when he starts making it sound as if the more CO2 there is in the atmosphere, the more plant growth there will be, that is where he strays from the facts, because it is not quite that simple. I live in Iceland, and for awhile there was extra plant growth due to rising CO2 levels, but at some point this extra growth levelled out. If there was a simple correlation between the two, it would have kept on rising, but it hasn't. Nature just isn't that simple.
Think of it this way. A man with a backpack full of meat is walking in the desert. He has enough food for weeks, but then he runs out of water. How long does he last? A long time? After all, he has enough food. No, if he doesn't get the water within a short time, he dies. This is a very simple example, and I know it doesn't completely apply to this situation with CO2 and plants. What I am trying to point out with this is that CO2 isn't the only thing plants need for growth. In fact, there are a lot of things that can hinder plant growth. Pests, heat, cold, how much water is available, how much sunlight there is, how much wind, and so on, come into play here. Other plant foods such as nitrogen and phosphorus come into it also. A lack of either of those two can hinder plant growth, even when there is enough CO2 in the air. Wrightstone is trying with this to make a simple equation out of something that isn't quite so simple.
What Wrightstone is trying to prove is that CO2 is irrelevant when it comes to climate change. The thing is the proof for why CO2 matters when it comes to climate change is grounded in basic physics and chemistry. Experiments on this started some 200 years ago. It's not a new idea. It‘s not something that Al Gore thought of to make your life more difficult. In my view Al Gore really is even quite irrelevant in all of this. He is only one of many people that are talking about climate change. What does matter is that the science of climate change is a sound one. It is the result of a great deal of research, by thousands of scientists, over a long, long, long time.
The whole book is Wrightstone's attempt to disprove basic climate science, but once one starts to actually look for the basis of his claims, all these proofs start to sound hollow because even though they are often based on facts, such as is in these two cases that I have gone into very, very lightly, he never really tells the whole story. He uses cherry picked data to make sure the facts are in line with his argument, leaps to conclusions when that is necessary to make the argument sound plausible, and so on and on. One can find examples of that all over this book. Look at the forest fire chapter for example, then look up the data for yourself. It's worth it. In short, chase up the data he uses and you‘ll see how he does it. A review like this is too short to actually take on all the problems I've found with this book, so I'm not getting any further into this now.
In the end, I think I'll neither laugh or cry at this book, because reading it, and thinking about it has been an educational experience. It is an interesting book, and Gregory Wrightstone is a clever, clever writer. This really is not badly done. The way this book is built up is very well done, and it sounds quite convincing. That is until one starts to look closely at the basis of the claims. That's when it falls apart. I'm not going to read it again, but it showed me quite well how this is done.
