The article discusses the implication of dust in the air in health, snow cover and rainfall in the U.S. It mentions that several factors including reduction in grazing, continued disturbance by grazing animals, and off-road vehicles and plows exacerbated by drought can result to dust in the air which is brought by gust. It states that the attack of dust in Southwestern U.S. skies affects human health and safety. It stresses that dust blankets can cause faster snowmelt, particularly in the San Juan Mountains of Colorado. It adds that dust can also affect the rainfall pattern, according to Imtiaz Rangwala who studies climate change in the American West.

    The Australian decade-long 'Millennium Drought' broke in the summer of 2010/11 and was considered the most severe drought since instrumental records began in the 1900s. A crucial question is whether climate change played a role in inducing the rainfall deficit. The climate modes in question...

    It is well known that most of the severe droughts in Amazonia, such as that of 1997, are El Niño-related. However, in 2005, the Amazon was affected by a severe drought that was not El Niño-related, as most of the rainfall anomalies that have happened in southwestern Amazonia are driven by...
