New Little Ice Age?
Dalton Minimum Returns
July 6, 2009 Russ Steele EXCERPT: Louis Hissink's Crazy World, blog by Louis a Geologist from Perth Australia has some thoughts on the current sun spot cycle. Sunspots reach a nadir lower than the Dalton Minimum Timo Niroma has posted his latest analysis of solar sunspots on his website.(Requires Microsoft Log in?) The yearly spot value of 2007 was already only 7.6 which is below the previous minimum in 1996 (with 8.6). The value dropped to 2.6 in 2008 and the smoothed value at the moment is 1.7 (December 2008). (In December 2007 it was 5.0 .) We must go to the year 1913 to find a lower smoothed value (1.5). The November 2008 value means that the cycle 23 has at least a length of 12.6 years. There has been only 2 cycles since 1749 longer than the cycle 23, the cycle 4 (1784-1798) just before the Dalton minimum and the cycle 6 (1810-1823 or the second of the Dalton cycles). The cycle 9 (1843-1856) had about the same length as we have now achieved (12.5 years). It began the series of 5 Jovian cycles and a cool climate in 1856-1913 (the Damon minimum). http://ncwatch.typepad.com/dalton_minimu...e-age.html ====================================== I would not be speculating an ice age on this little data,but the in the link is an interesting list that seems to point to even lower solar activity in the next few years. It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies. –William O. Douglas, U.S. Supreme Court Justice, 1952 |

Re: New Little Ice Age?
I've never had to log in to any of Timo's web pages. Perhaps you are looking at something different?
“We do not believe any group of men adequate enough or wise enough to operate without scrutiny or without criticism. We know that the only way to avoid error is to detect it, that the only way to detect it is to be free to inquire. We know that in secrecy error undetected will flourish and subvert”. – J Robert Oppenheimer. |

[/quote] I tried the link,and saw the block.I never had any problem with it before either.It could his restricted area of his main page? Timo's link that worked for me is in my other computer.I will have to dig it up soon and see I can still get in.
