Bill Gates’s book on climate change issues and solutions is exceptionally clear and simply written. Gates has an easy conversational style that makes the book a fun read, and he is clear-eyed about the problem and the solutions. He also stays away from politics, which makes the book a refreshingly apolitical read, especially in these times. Often Gates’s interest as a hardcore nerd shows, for instance when he tours a geothermal energy plant on a family vacation. Gates is also modest; he recognizes well that the world might be skeptical to hear about climate change solutions from yet another billionaire who thinks technology can solve all our problems. The difference though is that that technology *can* contribute substantially to addressing climate change, and unlike almost any other rich person, Gates has shows that he has both the breadth of knowledge and – as shown by his vast philanthropy – the public commitment to tackle this huge challenge.
Gates starts by making the sheer scale of the problem clear: Firstly, there are 51 billion tons of carbon dioxide added to the atmosphere every year, and we need to reduce that number to zero. The useful metaphor he provides is of a bathtub which is full. Even if we reduce the flow of water, the bathtub will overflow at some point. The only two solutions are to turn off the tap and to drain the water.
Secondly, the sheer number of sources that contribute to this number make it very challenging to foresee how we can solve the problem – almost every activity we undertake in our daily life, from brushing our teeth (the plastic in the brush released GHGs when manufactured) to eating (the food we eat releases GHGs when grown with fertilizer and transported). One corollary of this realization is that whenever we analyze a new technology for energy or climate change, we have to undertake a cradle-to-grave lifecycle analysis to gauge whether the tradeoff it provides is truly positive; in my view, a lot of people have this blind spot when they make exaggerated claims about solar or wind power for instance.
Thirdly, we are not working on a static target; the world’s population is not just growing but getting more and more energy-hungry, which means we have to work uphill against this increase in GHG production. These three problems might make us feel pessimistic or even hopeless, but as Gates says, there are many solutions in principle, and a few in practice that we can implement to address the problem.
Religion has always had an uneasy relationship with money-making. A lot of religions, at least in principle, are about charity and self-improvement. Money does not directly figure in seeking either of these goals. Yet one has to contend with the stark fact that over the last 500 years or so, Europe and the United States in particular acquired wealth and enabled a rise in people’s standard of living to an extent that was unprecedented in human history. And during the same period, while religiosity in these countries varied there is no doubt, especially in Europe, that religion played a role in people’s everyday lives whose centrality would be hard to imagine today. Could the rise of religion in first Europe and then the United States somehow be connected with the rise of money and especially the free-market system that has brought not just prosperity but freedom to so many of these nations’ citizens? Benjamin Friedman who is a professor of political economy at Harvard explores this fascinating connection in his book “Religion and the Rise of Capitalism”. The book is a masterclass on understanding the improbable links between the most secular country in the world and the most economically developed one.
Friedman’s account starts with Adam Smith, the father of capitalism, whose “The Wealth of Nations” is one of the most important books in history. But the theme of the book really starts, as many such themes must, with The Fall. When Adam and Eve sinned, they were cast out from the Garden of Eden and they and their offspring were consigned to a life of hardship. As punishment for their deeds, all women were to deal with the pain of childbearing while all men were to deal with the pain of backbreaking manual labor – “In the sweat of thy face shalt thou eat bread, till thou return unto the ground”, God told Adam. Ever since Christianity took root in the Roman Empire and then in the rest of Europe, the Fall has been a defining lens through which Christians thought about their purpose in life and their fate in death.

Throughout history there have been prophets of doom and prophets of hope. The prophets of doom are often more visible; the prophets of hope are often more important. The Danish economist Bjorn Lomborg is a prophet of hope. For more than ten years he has been questioning the consensus associated with global warming. Lomborg is not a global warming denier but is a skeptic and realist. He does not question the basic facts of global warming or the contribution of human activity to it. He does not deny that global warming will have some bad effects. But he does question the exaggerated claims, he does question whether it’s the only problem worth addressing, he certainly questions the intense politicization of the issue that makes rational discussion hard and he is critical of the measures being proposed by world governments at the expense of better and cheaper ones. Lomborg is a skeptic who respects the other side’s arguments and tries to refute them with data.
Lomborg has written two books on global warming, but his latest volume is probably the most wide-ranging. The title of the book is “False Alarm”, and the subtitle is “How Climate Change Panic Costs is Trillions, Hurts the Poor and Fails to Fix the Planet.” The book is about 225 pages, clearly and engagingly written, contains many charts and figures and the last 75 pages are devoted to references and a bibliography. The title sounds sensationalist, and while titles are often decided by the publisher, it succinctly captures the three main messages in the book. The first message is that panic about global warming leads people to think irrationally about it. The third message is that all the vocal fixes proposed for fixing global warming won’t make more than a dent in the actual problem. But the second message is perhaps the most important – that not only would global warming fail to alleviate the problems of the poor but it will make them worse. This puts the problem not just in a political but in a moral perspective. Lomborg’s book should be read by all concerned citizens interested in the subject, whether they agree with him or not.
