This chapter investigates how attitudes to weather and climate reflected experiences of the Enlightenment in Britain and its colonies. It also introduces some new information to show how assessing the weather conceived of the goals of British investigators' work and the extent to which they believed they had achieved them. Meteorology became a means for the scientific mastery of geographical space. Instruments were used in innovative ways in the eighteenth century to produce knowledge of geographical space. The studies have indicated how some of the cultural responses to Hurricane Katrina have deep roots. The weather apparently still has the power not just to disrupt the material lives, but also reflect on the shallowness of civilization in the incompletely enlightened age.
