The fact that Earth's climate is in a state of rapid change is now well established. Climate change is a notoriously difficult area in which to make accurate predictions. One of the major problems is that science has become very specialized, which makes assessing all the different factors that act on a system as large as a planet challenging. While the unusually high concentration of carbon dioxide in the atmosphere is certainly having some effect on climate, the influence of solar activity and cosmic rays on global temperature may be equally, if not more, important. If the sun's behavior changes, Earth's climate is likely to respond. Assessing these trends and the balance of probabilities is a matter of fierce debate.
Other important changes are also happening. There appears to be an increase in the number and severity of extreme weather events such as tropical storms, flash flooding, droughts, and tornadoes. There is also evidence that major geophysical events like earthquakes and volcanic activity appear to be increasing substantially. For instance:
In the last fifty years, the number of tornadoes has doubled and there has been a dramatic increase in the geographical area in which tornadoes are found.
The number of recorded earthquakes in the last century has increased by 500 percent and measurements of volcanic activity are up by at least 200 percent. This may be at least partly due to the increase in the number of seismic and volcanic detectors around the world. The spread of humans into what were once remote parts of the world may also be a factor. (Reference: Micheal Mandeville
Increase in Plasma
The increase in plasma entering our solar system affects our planet in a variety of ways. The incoming plasma is magnetized to the poles of the earth and concentrates in these regions, creating the effect of the polar auroras. The radiation belts around the planet and Earth's magnetic field are also affected. Scientists from the Russian Academy of Sciences are predicting wide-ranging and various changes for our planet. The direct effects of increasing cosmic rays include:
• Increased plasma generation in the ionosphere
• Increased magnetic storms in the magnetosphere
• Increased number of cyclones in the atmosphere
K. M. Hiremath, from the Indian Institute of Astrophysics in Bangalore, has studied variations in the Asian monsoons and concluded that there is a causal connection between solar activity, incoming cosmic rays, and rainfall. He has also found a significant connection with the cycles of El Niño.
