Large parts of Europe lie frozen under tons of snow. Snow has been falling on and off for over one week now and forecasts are predicting more in the next couple of days. In some places they are running out of salt and grit to keep the major roads free of snow and ice. In the UK people are scared that gas supplies will run low and since most heating is done by gas homes will become unbearable. While this is going on in the northern hemisphere it is raining in the south where it is summer. Landslides have killed people in Columbia and floods have inundated parts of Peru. It is entirely possible that the reverse will happen in June/July when there will be summer in the north and winter in the south. Hysterical reporters are using words like unprecedented and unforeseen in news reports. Unprecedented may be but why unforeseen? School children know that 75% of the earth's surface is covered by water so it stands to reason that even a slight rise in temperature will cause evaporation of millions of tons of water from the surface of the oceans. This will eventually come down as rain or snow given weather conditions. As the earth gets warmer we can expect this to become a regular event. This brings the disaster in Copenhagen into sharp focus.
