It is now more than two months since I had any useful rain. It was one of
the warmest (if not the warmest) winters on record. We have had hot days
(30C) already and it is not two weeks into spring. Out west on the plains
they are wondering if there will be any winter-planted crops. There were
bushfires in Sydney this week. The local fire burglars have been out, with
the dust kicked up by wind and the rising pollen count I have been almost
house bound. Not a good start. The BOM says ENSO indicators are neutral.
We can hope.
But (due to irrigation) the fruit trees are blooming and the asparagus is
up! Yay!

Seems like 10% of the planet is looking at desertification, which drives
farmers to more marginal agricultural areas that are more prone to
erosion (and take longer to regenerate topsoil), and creating more
opportunities for desertification.
Add to this that for every degree "C" higher, during the growing season,
rice loses 10% of it's crop. Present predictions are for a 1C to 3C rise
world wide by the end of this century.
