We are bombarded, almost on a daily basis, with horror stories about global warming, shrinking icecaps and diminishing rain forests.
I have no doubt that there is truth, possibly very important truth, in many of these stories, but I also wonder what has happened to the scientific scare stories of yesteryear.
Is the ozone layer still endangered ? Is it still even there at all, or is it back to 'normal' whatever that may mean ?
