message: To introduce speculation and controversy in the form of "Some scientists believe that solar variation drives climate change more than carbon dioxide does (see global warming)" clouds the article (making this part of the controversy), when it is enough to say the point is debatable. —The preceding unsigned comment was added by 3xstmx3 (talk • contribs) 22:06, 22 January 2007 (UTC)
thread_title:  Solar Variation vs. CO2 

message: "Whether there is a causal connection between low sunspot activity and cold winters is the subject of ongoing debate"
: As a Heliology major it absolutly sickens me that this is still the "politically correct" way of dodging the issue. Every major temperature drop for the last 1000 years have all been traced back to Solar output. Weather it's Carbon 14 tracers or actual documented sunspot counts. I hope the current inactive sunspot cycle (2 years late) cools this planet enough to shut these "Global Warming" people up.
No, that comment is simply incorrect and contradicts the available data. Most of the temperature drops of the last 1000 years can be best correlated with volcanic activity. While solar activity can influence climate, it is a minor effect and there is no simple correlation between the two factors. e.g., Solar activity has been declining since the mid 1980s, whereas temperature has risen more rapidly than any point in the last 10,000 years (the period over which we can reconstruct solar variability).  — Preceding unsigned comment added by Heliophysics (talk • contribs) 16:19, 18 October 2019 (UTC)

message: Although it is widely attributed to him, the name appears to have been in common use prior to his 1976 paper. See the links here. For the avoidance of doubt, it is not my blog that I am claiming is a reliable source, rather it is the book (conference proceedings) dated 1975 that I quote from and link to. I propose to edit the page to reflect this, but suspect that this will bring out the kooks and crazies so I want to give you a chance to defend the status quo first.

thread_title:  Jack Eddy didn't really name the Maunder Minimum 

message: An anon has questioned the statement ... more typical 40,000–50,000 spots in modern times. As the number doesn't correlate with the graph for a 30 year period (high by a factor of ten+) and the line has been in the article since the beginning of time ... Jan 2002. So, I've added a cite needed tag for now. Vsmith (talk) 23:39, 27 November 2010 (UTC)

message: "The winter of 1708-09 was extremely cold" Right, that is, in some Europe. Southern hemisphere did not have winter 1708-1709. It has, of course, winters 1708 and 1709. What about the rest of the northern hemisphere? --91.152.90.62 (talk) 22:35, 29 December 2010 (UTC)

message: Thanks to Vsmith for removing my goof — my wife interrupted me. I agree with removal of trivia, as previously discussed above. In light of Little Ice Age and Other observations, my intent was to add a new Significant concurrent events, starting with Lan_Xang#Latter_years where I have already put a link to the Maunder Minimum. In light of what's going on today, I think it important to link significant climatic events to articles on concurrent collapse of kingdoms and empires, and vice versa. In many articles, this has already been done. This is my first feeble attempt. What do others here have to say? --Pawyilee (talk) 15:43, 3 March 2012 (UTC)

message: How Could Spörer have observed fewer than 50 sunspots during one 30-year period within the Maunder Minimum, if the Maunder Minimum ended at 1715 and Spörer was only born in 1822?
:I see that you corrected the text to point out that Spörer was reporting observations by others. I checked the citation, and see that in fact this is a report of observations from 1672-1699, so I corrected that to read "Spörer noted that, during one 28-year period within the Maunder Minimum (1672-1699).

message: As regards the claim made in the current version of the article that, "no convincing mechanism for the solar activity to produce cold temperatures has been proposed," see: http://onlinelibrary.wiley.com/doi/10.1002/2014JD022022/full and the papers it cites.

thread_title:  Convincing mechanism 

message: Sun Spot Minima occur during the combined alignments of the four largest planets in 
our Solar System.  These Minima can be taken as two groups of three planets.
The alignment of Jupiter, Saturn, and Uranus occur every 208.653 0097 Years.
The alignment of Jupiter, Saturn, and Neptune occur every 409.257 4551 Years.
The alignment of all four occurs every 2898.886848 Years.
Since 2 times 208.653 0097 = 417.306 0194 Year is close to 409.257 4551 Years,
there are times when the forces applied by Saturn, Uranus, and Neptune all from
one side of the Sun, severely reduce the Force applied by Jupiter from the other
side of the Sun.
This alignment was centered in the year 1680, but was effective between 1680 plus and 
minus 35 years, ( between 1645, and 1715 ).  If this range holds true for the next Minima,
then it will be centered on 1680 + 409 = 2089.  If the plus and minus 35 holds true, then
the range of low Sun Spots and Cold temperatures will occur between 2054 and 2124.
The last Year the Rio Grande River Froze in Albuquerque N. M. was in 1715. The Sun Spots 
resumed in 1716. Those born after 2000 can comment here to see if this is correct, but 
wait until after 2054. 63.225.17.34 (talk) 18:43, 1 August 2016 (UTC)

message: The information above is partial to a global warming view. However science does NOT reliably trace Maunder solar states back to 0 A.D.
The Swedish polar ice cap studies of gas bubbles in ice show temperature curves back millions (and millions) of years.
If ever verified for a given accuracy, they show temperature swings have been wild in the past both too hot and cold for humans. In the millions of years we are on a small upswing of a much larger downswing which could either swing up or down historically (if it goes down as the major trend has, we enter an ice age is likely).
The scientists televised the study (ice core drilling) and results on The History Channel, as well as in publications.
ALSO:  the only big question one has reading the article IS UN-ANSWERED.  THE ARTICLE SHOULD BE REMOVED FOR TOTAL LACK OF UNDERSTANDING OF THE TOPIC.  The article states there is a predicted period of solar spots but not their period or predicted next event.
DELETE THE ARTICLE.  it has no substance whatsoever.
(p.s. my comment about being in the middle of a maximum could be wrong; it's by memory of my chatting with a SOHO researcher friend of mine, my memory may not be perfect.  the statement about 1/2 way through an ice age was glean from a variety of sources: at least 1/2 of which were wikipedia)

message: This article says auroral activity was normal during the Maunder Minimum: "During the Maunder Minimum aurorae had been observed seemingly normally, with a regular decadal-scale cycle..."

message: Somebody claimed the MM included the 5th (actually 7th now) warmest ever winter was during the MM. Given that the MM occupies 1/6 of the HADCET record, it seems disingenuous to suggest that this is some sort of evidence that the MM wasn't cold in winter.
