  Important issues about climate change are summarized and discussed:
  A large body of evidence shows that the world climate is getting warmer.
Climate models give a consistent explanation of this observation once
human-made emissions of greenhouse gases are taken into account. Furthermore,
the main source of greenhouse gases comes from the burning of oil, gas and
coal, mainly in the industrialized countries. Without any change of behaviour,
the possible predicted consequences of this climate change for the coming
decades are very disturbing. Today's (in)action's will have long-term
consequences for the entire biosphere and the living conditions of many future
generations.
  The combination of the various points related to the climate change leads to
a final question: "For how long will Humanity continue to bury its head in the
sand?"
