I've heard of the sunspot cycles that Philip Chapman mentioned, and, frankly, it has crossed my mind a few times over the last decade or so on questions of global warming. What sets off my alarm(ist) siren right away, though, is his blanket assumption that we're heading into an ice age, based on a single sunspot reading. How does he know which sunspot cycle we're even in? Are we in the standard 11 year cycle (meaning we're due for a standard sunspot minimum right about now)? Are we heading for a minimum in a larger 360 year cycle? Or an even larger 8000-10000 year cycle? The current evidence doesn't indicate that we're in anything, but a typical 11 year cycle currently, even by NASA's research: ![]() In other words, we're approaching a standard 11 year minimum, and, by 2012, it's predicted that we'll be heading for a potentially even busier maximum than even in the previous 11 year maximum. The low sunspot count that Chapman is fearful of was also noted, according to the graph, in the last cycle minimum in 1996-1997. In fact, it appears that, in late 1996, it was recorded that there was a brief period with no sunspots at all. Our ice age certainly didn't arrive after that, so, while Chapman mentions an interesting, scientifically notable theory regarding global climate and sunspots, it is still not scientifically responsible to start abandoning global warming solutions. The evidence, frankly, is just not there. |

Phil Chapman isn't a climate scientist. This guy, however, is, and he wrote an article debunking Chapman.
Warming trend has not been reversed | The Australian I'm not seeing anything on the SoHO website trumpeting a connection between the Sun and the climate, Phil Chapman's claims notwithstanding: Solar and Heliospheric Observatory Homepage |

I asked a member of the SoHO science team to respond to the Chapman article. Response as follows:
The Chapman article is full of misstatements, omissions, and errors. He says that SoHO not seeing sunspots is the harbinger of an ice age. This is nonsense. SoHO is not used to determine the sunspot number because it doesn't have sufficient resolution; ground-based observatories do that. The sunspot cycle has been shorter than normal for the last three cycles (10.4 years for each cycle) so it seems to be returning to a normal pattern of just over 11 years. The Dalton Minimum was several years longer, not several months. He claims that the "Earth has cooled by 0.7C in 2007" - odd then, isn't it, that 2007 was reported to be the 5th warmest year on record. In fact we have had 9 of the 10 warmest years in the last decade. It only dropped that amount in January; it recovered for the rest of the year. What he is actually referring to is that January was an AVERAGELY warm month, being ranked 64th of the last 128 Januaries; this has been way below the average for the last few years where most months have been in the top 20. What he fails to mention is that February, March, and April all were back up in the top 20. You can find similar errors and misstatements in every single paragraph of the article. Sorry to ruin Chapman's fun. But it's interesting that contrarians have to use these tactics to make their points - probably their only alternative since the actual data don't support their case. |

Easy now, people are trying to affirm biases and don't need pesky facts getting in the way.

This article supports my earlier post that even the Bush Admin. is on board with man-made climate change.
