Another reason for climate change on Earth has been discovered, with this threat coming not from humans but from the outer reaches of space.
According to this latest research, the effects of exploding stars can, in conjunction with the behavior of the Sun, influence the weather on Earth. In turn, this could result in either an increase or a decrease in temperatures.
The Effects on Earth of Exploding Stars
The study was conducted over a period of two years by the Technical University of Denmark. Its results seem to prove how cosmic rays that emanate from exploding stars, known as supernovae, alter the air molecules within the Earth’s atmosphere.
This leads to the creation of particles known as ions. In turn, these attract moisture and other elements that exist within the atmosphere. Provided they are of sufficient size, clusters of particles will create cloud formations.
Rain and shade produced by higher amounts of moisture in the air can have long-term effects on the weather. However, solar activity can also influence such conditions.
Magnetic emissions from an active Sun can reduce the effects of the cosmic rays. They could reduce the moisture content in the atmosphere. In turn, this would result in warmer temperatures.
The sun has been less active in recent years, which should lead to a more significant cloud coverage and cooler temperatures. As it is, the relationship between this natural climate change and the warming generally attributed to human activity was not explored by this recent study.
This made use of a sealed laboratory to simulate the upper atmosphere of our planet.
Scientists have expressed the belief that a combination of cosmic rays and solar activity were responsible for two different climate events in our planet’s history.
One is the warm period experienced on Earth about 1,000 years ago. The second is a cooler period that affected much of the second millennium and ended around the beginning of the 20th century.
It was during this “Little Ice Age” that celebrations known as “frost fairs” started taking place atop England’s famed River Thames, which often froze over in the wintertime.
