Extract from a book I am reading, "Childre... of the dar"
In 1787.
Boreholes were sunk near the outcrop and ten yards below the surface a 4ft high seam was discovered. A second black band of coal of around the same height was found twentyfive yards deeper and at 86 yards a third seam revealed itself. On hundred and forty eight yards below the surface a further 30" seam was discovered. Each on top of the other and running a NW to SW direction at the outskirts of Wakefield. (Yorks)
I make that four lots of global warming without mans intervention
So I assume it will happen again even if we didnt light another match.
