In a nutshell, the article seems to imply that the planet is absorbing more solar energy (almost a megawatt per square kilometer!) than it radiates back, and this is causing a thermal imbalance which in turn accelerates or triggers tectonic activity. But it seems unclear how they measure the deadliness of a quake. Are more people dying because the earthquakes are more intense, or because larger numbers of people tend to live in the areas affected by them?"
