If the tech is feasible, then do it on a small, individual scale: the area around one's own home, for example.

Done. When outside I will sit in the shade on hot days and in the sun on cold thereby controlling the incident solar radiation upon myself. I assure you it works.

it should be proved to be risk-free

There's no such thing in this life. But I agree that the reliability of the technology should be determined as best we can before applying it full scale.

applying the same Precautionary Principle

I reject this principle.

Since none of this is about climate change

It isn't none, at least not on my part. The historical evidence for significant global temperature swings is quite reliable. Significant global temperature swings will be very costly no matter the direction. If the cost of eliminating or moderating these swings is less, we should consider doing it.

I fully expect the Progressives and the GW crowd to go ballistic over any attempt to intervene in natural solar processes.

Agreed. I mean isn't it immoral to drive gas guzzling SUVs? Obviously we must do penance for it. Some technological quick fix doesn't satisfy the suffering requirement.

I agree that there is discernible climatic change. I doubt that more than 10%-15% is anthropogenic in origin. However, by *this*, I meant the hysterical attempts to either impose economic sanctions on development or the equally hysterical suggestions to somehow construct some sort of super global sunshade when we have no idea how this will effect global climate including wind/rain/ocean currents, et al.

We all utilize shade and sunlight to regulate our own micro habitat. I simply do not trust any agency or group to do this on a global scale.

While I also agree that P3 is ridiculous, it is quite irritating to be told we should undertake some huge technological attempt to deflect insolation on a global scale because the risk of extreme accelerating warming is "predicted". We have a dynamic, cyclic climate. I personally doubt we are going to experience warming on such a scale that we need to spend huge sums of resources, time and talent to redirect insolation. It is actually, from all I have read, more possible that the opposite might occur and we might experience another little ice age before we experience super warming. Since I live at 44 degrees North, in an area that was free of glaciation the last number of times, I don't really see the need for methods to increase global insolation at this point, either. I believe we will cope with whatever happens on smaller scales.

Isn't it interesting that only the American SUVs are implicated? Are there no SUVs anywhere else in the world? Only evil Americans are supposed to do penance. I am surprised the hysterics haven't come up with some way to exempt non-Caucasian Americans from all such sacrifice.
