In his review or climate-change science and policy interactions, Shardul Agrawala points to a gradual move from policy as a driver for the advancement of science to a situation where scientific results are themselves influencing policy development (Agrawala 1999).

This is a continuing dialogue that can trace its roots back the best part of two centuries. By the beginning of the nineteenth century Jean Baptiste-Joseph Fourier had already developed his suggestions that the Earths atmosphere traps heat; citations as early as 1807 can be found, but the first separate publication is that or Fourier ( 1824). The work of John Tyndall, measuring the radiative .adsorption of atmospheric constituents was published in the second half of the century (Tyndall. 1863) and by the end of the nineteenth century. Svante Arrhenius had published work on the likely effects of coal burning on atmospheric CO2 (carbon dioxide) concentration and subsequent warming (Arrhenius 1896).

At the start of the twenty-first centuary we are now in a position where the political agenda is adapting to scientific advances. This dependence on science in the political arena considerably raises the expectations on science to be an accurate and reliable information provider. This chapter discusses how well the expectations for quality products can be met using remote-sensing methods. ds.
