How do sunspots fit into global warming?

On the last day of August, scientists spotted a teeny-weeny sunspot, breaking a 51-day streak of blemish-free days for the sun. If it had gone just a bit longer, it would have broken a 96-year record of 53 days without any of the magnetic disruptions that cause solar flares. That record was nearly broken last year as well.

Wait, it gets even more exciting.

During what scientists call the Maunder Minimum — a period of solar inactivity from 1645 to 1715 — the world experienced the worst of the cold streak dubbed the Little Ice Age. At Christmastime, Londoners ice-skated on the Thames, and New Yorkers (then New Amsterdamers) sometimes walked over the Hudson from Manhattan to Staten Island.

Of course, it could have been a coincidence. The Little Ice Age began before the onset of the Maunder Minimum. Many scientists think volcanic activity was a more likely, or at least a more significant, culprit. Or perhaps the big chill was, in the words of scientist Alan Cutler, writing in the Washington Post in 1997, a "one-two punch from a dimmer sun and a dustier atmosphere."

Well, we just might find out. A new study in the American Geophysical Union's journal Eos suggests that we may be heading into another quiet phase similar to the Maunder Minimum.

Meanwhile, the journal Science reports that a study led by the National Center for Atmospheric Research, or NCAR, has finally figured out why increased sunspots have a dramatic effect on the weather, increasing temperatures more than the increase in solar energy should explain. Apparently, sunspots heat the stratosphere, which in turn amplifies the warming of the climate.

Scientists have known for centuries that sunspots affected the climate; they just never understood how. Now, allegedly, the mystery has been solved.

Last month, in another study, also released in Science, Oregon State University researchers claimed to settle the debate over what caused and ended the last Ice Age. Increased solar radiation coming from slight changes in the Earth's rotation, not greenhouse gas levels, were to blame.

What is the significance of all this? To say I have no idea is quite an understatement, but it will have to do.

Nonetheless, what I find interesting is the eagerness of the authors and the media to make it clear that this doesn't have any particular significance for the debate over climate change. "For those wondering how the (NCAR) study bears on global warming, Gerald Meehl, lead author on the study, says that it doesn't — at least not directly," writes Moises Velasquez-Manoff of the Christian Science Monitor. "Global warming is a long-term trend, Dr. Meehl says. ... This study attempts to explain the processes behind a periodic occurrence."

This overlooks the fact that solar cycles are permanent "periodic occurrences," a.k.a. a very long-term trend. Yet Meehl insists the only significance for the debate is that his study proves climate modeling is steadily improving.

I applaud Meehl's reluctance to go beyond where the science takes him. For all I know he's right. But such humility and skepticism seem to manifest themselves only when the data point to something other than the mainstream narrative about global warming. For instance, when we have terribly hot weather, or bad hurricanes, the media see portentous proof of climate change. When we don't, it's a moment to teach the masses how weather and climate are very different things.

No, I'm not denying that man-made pollution and other activity have played a role in planetary warming since the Industrial Revolution.

But we live in a moment when we are told, nay lectured and harangued, that if we use the wrong toilet paper or eat the wrong cereal, we are frying the planet. But the sun? Well, that's a distraction. Don't you dare forget your reusable shopping bags, but pay no attention to that burning ball of gas in the sky — it's just the only thing that prevents the planet from being a lifeless ball of ice engulfed in darkness. Never mind that sunspot activity doubled during the 20th century, when the bulk of global warming has taken place.

What does it say that the modeling that guaranteed disastrous increases in global temperatures never predicted the halt in planetary warming since the late 1990s? (MIT's Richard Lindzen says that "there has been no warming since 1997 and no statistically significant warming since 1995.") What does it say that the modelers have only just now discovered how sunspots make the Earth warmer?

I don't know what it tells you, but it tells me that maybe we should study a bit more before we spend billions to "solve" a problem we don't understand so well.

The important point of this

The important point of this editorial is that for the moment at least, we seem to be entering a cooling phase. This summer's weather in Maine is not proof of that. Rapid ice melting in the Arctic is not evidence to the contrary. WORLD WIDE temperatures are declining. Antarctic Ice (where 90% of the worlds ice is found) is increasing at a rapid rate. For all we know we could be entering another period of glaciation. The warming periods between glaciations typically last for about 12,000 years. The glaciers that covered Maine began receding about 12,000 years ago. We are still living within the greater "ice age" called the Holocene Age, and no one knows when it will end. Civilization has benefited from the warming trend over the past 12,000 years. When the ice comes back, it will be here for a hundred thousand years if history repeats itself.

Global warming fears have driven public policy decisions that reward industries like wind power that claim to have an impact on climate change by reducing fossil fuel burning to generate electricity. Those claims are false and the public policy that supports them with obscene amounts of subsidies is misguided at best and corrupt at worst.

The scars left by Angus King's wind turbine construction will be there until the next glaciers scrape the tops off the mountains and redefine Maine's landscape. That may happen sooner than later.

I read the first sentence of

I read the first sentence of Joe's; "The sumn spots mostly due to nuclear weapons testing during world war two which caused a great damage to the environment." I then knew, immediately, that Joe Ziemer simply doesn't know what the hell he's talking about. It's nearly impossible to follow his line of reasoning - if reasoning it truly is. How could nuclear weapons testing cause sun spots? The one has absolutely nothing to do with the other.

Look at the destruction and

Look at the destruction and damage done to Hiroshima and Nagasaki which you have left out of your posting completely and also the evidence of what the nuclear wastes had caused in several towns higher rates of cancer. Most of the sun spots occur in cities and townships were nuclear pollution and evidence measures are quite high. Which could be a pulling back as of a band-aid with the ozone layer and that would make sense as though people continually deny that. Are you saying that you do not follow the higher rates of cancer and equations of nuclear wastes peeling back the orbital layer of the ozone? I do know what I'm talking about maybe you should study it before making a one sided diagnoses.

The sun spots mostly due to

The sun spots mostly due to nuclear weapons testing during world war two which caused a great damage to the environment. Using live sheep to conduct testing to see the radiation damage done to the animals. Which is more likely the cause of peeling back the ozone layer and causing a great damage also in the way in which we refine gasoline and several other byproducts. Depleted uranium rounds also have led to several of those effects which leads that pollution yet again is our strongest enemy for our own greed and gain. I don't believe you really have any understanding of that you do not relate that information in your article Mr. Goldberg is the periodic occurrence that you do not have that information at hand? In scientific data collections that would have to be included with any research. The Christian Science monitor neglects that information in the article and does not truly relate the byproducts which are produced in the air.

Within that live firing on the sheep's in decommissioned boats was used as to what amount should be added on the bombs dropped on Hiroshima and Nagasaki to incline itself to how quickly and how much damage atmospherically and to people that it would do. Refining petrol and other materials causes much of the damage to the environment you suggest that investing billions into something we know little about is useless. I hinder you with a question then; in New York there is a city which was used as a nuclear refuse dump, unwillingly several townspeople had no knowledge, cancers spread rather quickly, and the environment was damaged catastrophically. How then can you say that we have no knowledge and that investing the billions into something which we do not know as you phrase, then we know the natural damages, and how can that be that we do not know; unless you, yourself have no knowledge? That knowledge comes from my grandfather a Corpsman during WWII relating the stories of nuclear weapons testing.
