The 2007 hundred year drought in parts of New Zealand looks like becoming the norm - for our life time, because of Chinese pollution.
November 2008 in the Waikato was even drier than 2009, then autumn 2010 has been even drier for longer. Typically, our summer rains come from the north, but last year and this year so far, rain forecasts from the north seldom eventuate in much. The last lot came from the north and then south so we got a 32 mm, while some got only 10 mm. If we'd had the rain forecast in last three summers, we would not have had droughts. Long term forecaster Ken Ring is accurate in winter when rain comes from the south west, but as with the Weather Office, rain he forecasts from the north doesn't get here. The reason is known by a few, but not by either of the above. Our summer droughts look like being caused by China's pollution from their dirty coal burning power stations which they are building at one a week, and from their factories, both of which belch large dust particles from soot. A friend who works at Huntly power station in the Waikato, told me that there are so many filters in their funnels that nothing could get through. Occasionally one sees steam rising, but never soot. We were taught at school that in the dusty dry areas, the large dust particles make large drops of rain while fine particles make small drops. So the result was floods in the north of New Zealand and Australia, and droughts in the south. Coastal Oregon has also had heavy rain and satellites show pollution blowing across the Pacific to USA. Norfolk Island didn’t have a 2008 summer, just rain. The world’s problem is not warming or cooling, it is simply pollution caused by soot from Asian power generation and coal burning factories with little filtering in their chimneys. It has been well documented by CSIRO in Australia that pollution from Asia has been a cause of the Sahara Desert spreading south at about 6 km a year for a long time. Northern Nigeria is now getting sand blown over their crops. Vaughan Jones |
