Dr.Leif, in a very new paper www.nature.com/articles/srep15689 the authors claim to know the behavior of the sun ( it's activity) up to year 3200. They reconstructed the activity (SSN) of the last 1000 years with "remarkable agreement" to the observations.
(Source: fig. 3 of the mentioned paper) What's your opinion about the method in the paper and the conclusions? best Frank PS: They confirm that SC 25 won't be an "extra weak":
Dr. Svalgaard, if I remember correctly your view is that the stratosphere is heated from above and the troposphere is heated from below. As I understand this article link there is a claim that much of the stratospheric heating is from below. Is there any merit to this claim in your opinion?
The entire paper is based upon the premise that there will be a significant increase in galactic cosmic rays within the solar system do to reductions in the solar wind. It is my understanding that while the current solar minimum has been unusually deep, most predictions for cycle 25 have reasonably normal expectations for solar activity. Is this opinion still current, or have there been developments?
