Kevin at www.solarcycle24.com/ is reporting the onset of solar cycle 24, there is a discussion board there too.
Centuries of sunspot data show that periods of low sunspot numbers correlate with periods of cool climate. Solar minimum between cycles 23 and 24 is expected to be in a few months time.
Starting in December 2006 I have several blog posts drawing attention to contrasting predictions re the strength of cycle 24, these are all linked later in this post.
But first let’s just quickly list links to predictions by various climate research groups.
First in May 2006 Dr Hathaway of NASA predicts a weak cycle 25.
Then in December 2006 Dr Hathaway is predicting a big cycle 24 with a smoothed sunspot number of over 160.
In April 2007 a forecast issued by the NOAA Space Environment Center in coordination with an international panel of solar experts. NOAA says, “The late decline of Cycle 23 has helped shift the panel away from its earlier leaning toward a strong Cycle 24. Now the group is evenly split between strong and weak.”
Solar minimum between cycles 23 and 24 is expected to be in a few months time. The next few years will be fascinating to watch unfold as the predictions for cycle 24 can be refined. Currently the range of preidctions by NOAA are seen here.
I have several Blog posts drawing attention to David’s important prediction that Solar Cycle 24 would be delayed, shorter than other groups were saying and could in his opinion lead to a cooling climate.
On December 16 2006 I drew attention to;
Contrasting forecasts for Solar Cycle 24
then a couple of months later I posted
Has anybody seen any recent sunspots ?
February 23rd, 2007
Then on March 27 I posted David Archibald’s new paper predicting global cooling ahead;

Solar Cycle 23 not ending yet
July 6th, 2007 Download a PowerPoint presentation of David Archibald’s latest edit of his paper, “The Past and Future of Climate” presented at the Lavoisier Conference in Melbourne June 2007.
David Archibald can be seen and heard on YouTube talking about his 4 Part paper “Past & Future Climate change”.
