A typhoon in the Philippines, flooding in India and Bangladesh -
disasters such as these have always faced mankind and there is no much
that we can do about them. But now it seems likely that some of these
climatic problems are being made worse by the effect the man has had on
the planet's atmosphere. Global warming is already affecting the climate
and, if not checked, could mean that in forty year's time large areas
of the world surface will change dramatically. Our children's world
could look very different to the one we know now.
