Query: Weather instabilities as a warning sign for a nearby climatic tipping
  point?   Using in a simple way the theory of non linear dynamical systems, we show
that increasing climatic instabilities may be a qualitative warning sign for
the occurrence of a nearby bifurcation, yielding a discontinuous and sudden
climate tipping towards an unknown and unpredictable state. The possibility of
an accurate prediction of the occurrence time of such a transition is also
discussed in terms of the approach of a critical point.
