Scorched Earth

A few days ago I headed north, driving from our home on the French Côte d’Azur to our home in the Brie, mid-centre between Paris and Reims, fifteen minutes from the Champagne district. I love these long trajectories penetrating and discovering France. In the years I have lived here I have driven in every season, at every hour of the day or night and some of the trips have been memorable for the landscapes, colours, temperatures beyond the car windows.

Down in the south, most days this late June and first half of July, the temperature has hovered at around 30C, occasionally rising to 32 or even 33C. Because we live within view of the Mediterranean, the sea breezes, the humidity, keep the climate reasonably constant. No rain down our way for months on end is to be expected and we have the vegetation to handle it, and plenty of it, including the olive tree.

It has a magnificent and complex perspiration system and a message service between root, branches and the underside of its leaves that monitors the level of water dispensed during perspiration. If a serious drought sets in, a warning signal goes up through the tree, telling it to hold back its sweat, to conserve the liquid and use it for survival. It really is extremely sophisticated and remarkable.
