Sun Spot increase recent history
From a New Scientist article from November 2003: “There have been more sunspots since the 1940s than for the past 1150 years (combined).” That is a 1825% increase. Sunspot numbers were derived from levels of a radioactive isotope found in ice cores taken from Greenland and Antarctica. Sunspots are the precursors of solar flares and coronal mass ejections and reflect the internal state of the sun.

List of Changes to Our Solar System
These increases seem to be due to increased activity from the sun. If that is true, such events will continue to increase over the next few years.
- A 400% increase in the speed that solar particle emissions are capable of traveling through the energy of interplanetary space (NASA 1997-2001)
- A 400% increase in the overall number of natural catastrophes on Earth between 1963 and 1993 (Dmitriev 1997)
- A 230% increase in the strength of the Sun’s magnetic field since 1901 (Lockwood, 1998)
- 9 out of the 21 most severe earthquakes from 856-1999 AD occurred in the 20th century (Russian National Earthquake Information Center, 1999)
- A 500% increase in Earth’s volcanic activity between 1875 and 1993.
