It's Not Rocket Science

From the DUH department....

Scientists at NASA have found a correlation between solar activity cycles and the recent warming trends that the global-warbling greenieweenie alarmists have been telling us about - when they aren't talking about shutting down the skeptics by murder or enacting taxes of dubious repute. (Story from Science Daily here.)

Over the past century, Earth's average temperature has increased by approximately 0.6 degrees Celsius (1.1 degrees Fahrenheit). Solar heating accounts for about 0.15 C, or 25 percent, of this change, according to computer modeling results published by NASA Goddard Institute for Space Studies researcher David Rind in 2004.

The sun is relatively calm compared to other stars. "We don't know what the sun is going to do a hundred years from now," said Doug Rabin, a solar physicist at Goddard. "It could be considerably more active and therefore have more influence on Earth's climate."

Or, it could be calmer, creating a cooler climate on Earth similar to what happened in the late 17th century. Almost no sunspots were observed on the sun's surface during the period from 1650 to 1715. This extended absence of solar activity may have been partly responsible for the Little Ice Age in Europe and may reflect cyclic or irregular changes in the sun's output over hundreds of years. During this period, winters in Europe were longer and colder by about 1 C than they are today.

I know that the man-as-the-measure-of-all-things ideology is comfortingly arrogant, but there are forces of nature that are beyond our control. And they have a much bigger impact on our planetary climate systems than does your choice between a Prius and an Land Rover. Heck...plankton probably have a bigger impact.

Since then, there seems to have been on average a slow increase in solar activity. Unless we find a way to reduce the amount of greenhouse gases we put into the atmosphere, such as carbon dioxide from fossil fuel burning, the solar influence is not expected to dominate climate change. But the solar variations are expected to continue to modulate both warming and cooling trends at the level of 0.1 to 0.2 degrees Celsius (0.18 to 0.26 Fahrenheit) over many years.

Like many studies, this conclusion was based less on hard data and more on questionable correlations and inaccurate modeling techniques. (Not to mention that the political machine - both in national policy and academic policy - is shamelessly in the greenieweenie court.)

The inconvertible fact, here is that even NASA's own study acknowledges that solar variation has caused climate change in the past and is likely the main culprit for current trends. And even the study's members, mostly ardent supports of AGW theory, acknowledge that the sun may play a significant role in future climate changes.

All I have to say is this: As Al Gore and other people who stand to make a lot of money from global warming scare tactics will tell you, “the science is settled.” Unless you drive a hybrid, stumble around in the dark at night, and only eat things you find in your yard, you’re killing the planet.

So I don’t see what a big fat ball of hot gas way up in the sky has to do with anything.

But enough about Al Gore in his private jet.
