ScienceDaily (July 6, 2011) — Decreasing autumn and winter rainfall over southern Australia has been attributed to a 50-year decrease in the average intensity of storms in the region — a trend which is forecast to continue for another 50 years.
In an address July 7 to the International Union of Geodesy and Geophysics conference in Melbourne, CSIRO climate scientist, Dr Jorgen Frederiksen, said these changes are due to reductions in the strength of the mid-latitude jet stream and changes in atmospheric temperatures. The jet stream comprises fast moving westerly winds in the upper atmosphere.
It has already dried up to 200% of normal.
CO2 changed its mind in the last couple of years.. it even decided to stall temperature rises.. CO2 is more intelligent than some scientists.
