"The sun has gone very quiet as it transitions to Solar Cycle 24.
"Since the current transition now exceeds 568 spotless days, it is becoming clear that sun has undergone a state change. It is now evident that the Grand Maxima state that has persisted during most of the 20th century has come to an abrupt end.
"(The sun) might (1) revert to the old solar cycles or (2) the sun might go even quieter into a "Dalton Minimum" or a Grand Minima such as the "Maunder Minimum". It is still a little early to predict which way it will swing. Each of these two possibilities holds a great threat to our nation.
"We are now at a crossroad. Two paths lie before us. Both are marked with a signpost that reads "Danger"!
Down one path lies monstrous solar storms. Down the other path lies several decades of crushing cold temperatures and global famine."
"Climate change is primarily driven by nature. It has been true in the days of my father and his father and all those that came before us. Because of science, not junk science, we have slowly uncovered some of the fundamental mysteries of nature. Our Milky Way galaxy is awash with cosmic rays. These are high speed charged particles that originate from exploding stars.
"Because they are charged, their travel is strongly influenced by magnetic fields. Our sun produces a magnetic field wrapped in the solar winds that extends to the edges of our solar system. This field deflects many of the cosmic rays away from Earth. But when the sun goes quiet (minimal sunspots), this field collapses inward allowing high energy cosmic rays to penetrate deeper into our solar system.
