Dust storm increase

What is causing the worldwide increase in these immense dust storms. Sometimes, as in China and London, they have a red color and are blamed on the Sahara.  [and from another]http://www.dailymail.co.uk/news/article-3043849/Mystery-surrounds-spate-huge-dust-storms-world-year-grounded-flights-blotted-sun.html  April 17, 2015.  Experts cannot pinpoint the reason behind the spate. The footage of the dust storm in Belarus, filmed from a high rise apartment, shows traffic moving along a busy street. The storm was caused by a cold front moving in from the Ukrainian-Belorusian border. A raging sand storm sweeps in on the city of Golmud in north west China, where 200,000 people live. China’s Meteorlogical Centre issued a blue alert as the sandstorms swept across the north of the country. Golmud was left covered in a remarkable red haze when the sand cloud blew across the city.  The Shard, one of London’s most iconic buildings, is pictured shrouded in ‘blood rain’ earlier this month. In December a small town in Queensland, Australia, experienced a dust storm (pictured) that residents said was unprecedented in magnitude.  

Other than the wobble worsening, what is causing the massive dust storms which are undeniably on the increase around the globe? Some of this is caused by the red dust being increasingly delivered by the wafting tail of Planet X. This dust is a stealth dust storm in the main, as it can be seen at dawn or dusk or when the Sun’s glare is diminished in some way, but otherwise is perceived as merely a haze in the air. In regions where humidity or rain pull the red dust from the air and attach it to the soil or vegetation, the dust in the air is temporary. But in dry or desert regions, such as central China or Australia, the dust can be lifted during wind storms. The red dust from the tail of Planet X thus compounds the dust normally found in these regions.
