La réunion dans ce volume des deux ouvrages de Théophraste, Les Signes du temps et Les Vents se justifie à la fois par la proximité de leur sujet et par leur situation chronologique : le second (vers 310 av. J.C.) renvoie explicitement aux Signes (333-330) en précisant (§ 5) « la question des pluies a été traitée ailleurs plus longuement ». Au préambule modeste qui sied à la jeunesse de l’auteur, succède un développement en quatre parties liées par des formules de transition : les signes de pluie, de vent, de tempête et de beau temps. On y remarque la finesse de l’observation directe non seulement du ciel, mais aussi du comportement des animaux, sauvages ou domestiques. Les Vents s’en distinguent par un élargissement du secteur géographique considéré et surtout par l’analyse, généralement pertinente, des phénomènes météorologiques au sens moderne du terme

Global warming skeptics often fall back on the argument that the scientific case for global warming is all model predictions, nothing but simulation; they warn us that we need to wait for real data, "sound science." In A Vast Machine Paul Edwards has news for these doubters: without models, there are no data. Today, no collection of signals or observations--even from satellites, which can "see" the whole planet with a single instrument--becomes global in time and space without passing through a series of data models. Everything we know about the world's climate we know through models. Edwards offers an engaging and innovative history of how scientists learned to understand the atmosphere--to measure it, trace its past, and model its future. Edwards argues that all our knowledge about climate change comes from three kinds of computer models: simulation models of weather and climate; reanalysis models, which recreate climate history from historical weather data; and data models, used to combine and adjust measurements from many different sources. Meteorology creates knowledge through an infrastructure (weather stations and other data platforms) that covers the whole world, making global data. This infrastructure generates information so vast in quantity and so diverse in quality and form that it can be understood only by computer analysis--making data global. Edwards describes the science behind the scientific consensus on climate change, arguing that over the years data and models have converged to create a stable, reliable, and trustworthy basis for the reality of global warming.
