The global warming crisis emerged from a belief that small rises in CO 2 concentrations result in large knock-on effects, or strong positive feedbacks. These remain conjectural, as the forcings and feedbacks are poorly understood. Just how much of an effect does a rise in CO 2 have a little, or a lot? Hence the importance of new and better studies in the area of climate science dealing with attribution.
