Review of the hardback: 'As the 46th title in the Cambridge astrophysics series, this book on sunspots and starspots lives up to the high standards of many of the titles in this series. Both Thomas and Weiss are well-known experts in the field of spots on both the Sun and other stars … The authors … discuss more recent changes in Earth's temperature and, following a series of well-reasoned arguments, conclude that global warming by anthropogenic greenhouse gases is indeed a serious problem for mankind.'
