E. increased dust particles in Earth's atmosphere  

Explanation:

Ice age is the name given to the period where thick layers of ice cover large areas of the earth. These periods can last thousands of years and dramatically change the characteristics of the planet. There have been some very significant ice ages in the history of the planet. In the late nineteenth century, much research showed that there were several ice ages that alternated with interglacial periods.

Many scientists believe that we will live a new ice age in 2050. This ice age, though expected shortly, will bring catastrophic results to the life we know. One certainty we have is that if this ice age occurs, it will be caused by human interference with nature and all the degradation that man has caused to the environment. In addition, this ice age is likely to be triggered by the factors likely to cause an ice age: volcanic eruptions, clustering of continents near the poles and increased dust particles in Earth's atmosphere

true is the final answer!
