What will the left's next bogeyman be?

The American Thinker reminds us yet again that it is the sun which controls temperatures on the Earth:

During today's Summer Solstice, the Sun will attain its highest point north of the celestial equator. In the Northern Hemisphere, Sol will work its light and warmth wonders on its orbiting child longer than on any other day of the year, while those living south of the equator experience a conversely cooling phenomenon. What better day to be reminded of the definitive source of all climate flux on the planet?

Indeed, scientists have observed the direct connection between solar activity and Earth's climate for centuries. In the 19th, Edward W Maunder discovered a 70 year period centuries prior in which sunspot activity all but ceased to be. That period (The Maunder Minimum) coincided with the globe's coldest of the last millennium (The Little Ice Age). Then, as sunspot activity increased again around 1750, so did average global temperatures.

Coincidence, you say? How's this -- less than 100 orbits of the Sun later, solar activity once again dropped off (The Dalton Minimum) and global temperatures again responded sympathetically. And, as before, the return of sunspot activity translated to an increase in degrees Celsius.

Since 1950, we've been in a period termed the "Modern Maximum," for sunspot levels have remained relatively elevated. Remarkably, during this current heightened solar activity era, the planet seems to once again be growing warmer.

And just which human activities might be causing this totally unexplainable shift -- alarmists want to know?

Well, hundreds of modern historical studies have successfully correlated solar variations with terrestrial climate observations. These "proxies" run the gamut from glacial core samples and tree-ring chronologies to sea sediment samples and other repositories of plant and animal materials. Contemporary dating techniques then provide remarkable association between the climactic climate stories they tell and documented solar observations of the time.

I wrote about a wonderful example of this technique in March, when a group of NASA scientists employed historical Egyptian records of the annual water level of the Nile River as a climate proxy. These intrepid explorers discovered that during times of high solar flare activity (observed on Earth as auroras and well documented) river conditions were drier while fewer outbursts from Sol left them wetter.

So then -- the common sense, if not the science, would seem to be settled, wouldn't it?

After all, faced with a demonstrable pattern of a brighter Sun (which increased sunspots signify) forcing higher global temperatures while a dimmer Sun produces a cooler climate, anyone boasting triple-digit IQ should be led to one inexorable conclusion.

Needless to say, that conclusion won't contain the words carbon, footprint, greenhouse, SUV, Kyoto, reforestation, emissions, gases, climate models, acidification, anthropogenic, targets, timetables, sinks, caps, offsets or, especially, United Nations.

Most scientists possess at least some integrity (unlike most politicians) so they will not continue to lie or look the other way while others lie for very much longer. Even for lucrative grant money.

But the government-loving statist socialist politicians and activists will not surrender one hobgoblin with which to frighten the great unwashed until they have another all primed and ready to go.

Think about it. When is the last time you heard anything about ozone depletion? Ozone depletion lost most of its ability to frighten the masses when the knowledge that ozone is created by the ultraviolet light from the sun reacting with the upper atmosphere. As long as the sun shines there will be an ozone layer. This is what led to the manufacturing of global warming alarmism.

You see people who are not scared out of their wits about something will not hand over their wealth or their freedom to the state. Since the global warming house of cards is collapsing the Anointed Class of Enlightened Leaders who just know all the way down to the tips of their tippy toes that it is their holy destiny to shepherd the great heard of sheep grazing the pastures of flyover country will need a new issue to dress up in a red suit, glue a pointed tail on and hand a pitchfork.

What do you think it will be?
