You sir are correct. Why NASA doesn't know this is impossible for me to understand. Since the Sun is not a solid ball but more like a liquid cauldron, the orbiting planets pull and tug at it like the moon and sun do on earths oceans causing tides. When the large planets, Jupiter, Saturn, Neptune and Uranus line up together they really do a number on stirring up the sun and then we get plenty of magnetic fields getting twisted all over the place. When they hit the upper levels of the sun we see sunspots from these magnetic whirlpools.
When the major planets are more evenly dispersed in their orbits they don't create quite so much havoc and the sun is calmer. There is a regular cycle of between 172 and 178 years that these extreems happen.
We are now in the doldrums, so to speak. With the less energetic sun magnetic fields the earth is left to bask uninterrupted in the cosmic rays from all over the universe. Cosmic rays that would be swept up by the energetic field of the sun can now make it into the atmosphere and collide with molecules in the lower atmosphere and help to create clouds. Clouds shield the earth from sunshine and reflect it back out into space. Volia, global cooling.
There is a lot I haven't covered but basically this is the story and it has been known now by science for over a decade. Why NASA would make such a silly announcement is beyond me.
