The future for the environment on planet Earth. Professor Sir Brian Hoskins (Imperial College London and University of Reading, UK). Abstract: The activity of humans has led, over time, to local and regional changes in their environment. However, in the latter part of the twentieth century, their impact on the global environment became apparent with the appearance of the stratospheric ozone hole and the increasing evidence for global warming. In this talk, the current status of global environmental problems will be assessed and the outlook for the rest of the twenty-first century and beyond will be discussed.
