The climate has traditionally been viewed as a composite of processes acting each over relatively narrow ranges of time scales. The most obvious are those associated with the daily and annual cycles, but there are many others: for example El Nino and the orbital (Milankovitch) cycles associated with the ice ages. The “in between” scales are are uninteresting “background noises”. However, most of the variability is in these wide scale range (“scaling”) processes: they are foreground, not background processes. This proposal is centred on re-establishing the primacy of these scaling processes and examining the consequences for understanding the climate of the past, present and future.

传统上，气候被视为在相对较窄的时间范围内各自作用的过程的复合体。最明显的是与每日和年度周期有关的周期，但还有许多其他周期：例如，厄尔尼诺和与冰期有关的轨道(米兰科维奇)周期。“介于两者之间”的音阶是乏味的“背景噪音”。然而，大多数可变性是在这些大范围的(“缩放”)过程中：它们是前台过程，而不是后台过程。这项建议的核心是重新确立这些衡量过程的首要地位，并审查对理解过去、现在和未来气候的影响。
