Global Warming Experiment, updated

Continuing to work on my counter to the greenhouse effect/global warming.
I’m not as happy with my test prototype as I was. I did what every researcher should do, gather lots of data. The difference between shaded and sunny earth temperatures is clear, in the range 15ºC to 20ºC in late afternoon, but I’m getting readings from the plastic surface that are much higher than I think they should be. Meantime, the plastic is cool to the touch, indicting that it’s not absorbing heat. I want to make sure that the plastic isn’t converting incoming short-wave solar radiation to long-wave infrared, which would defeat the purpose of the panel, increasing albedo (reflected energy) while limiting insolation (absorbed energy). I’m using an infra-red based thermometer, so I’m getting information that an ordinary contact thermometer wouldn’t give. I plan on trying one of those today.
I was thinking as I drove down the interstate that it would be simple to line both sides of the interstate with panels. And then it occurred to me that we’ve been changing the insolation/albedo equation already. Black, rough-textured asphalt absorbs insolation more and decreases albedo. And we’ve got thousands of miles of that crossing our southwestern deserts. I don’t know that anyone has documented this; heat island effects of cities is known, but I suspect the square meter count of absorbent surfaces outside of cities is at least as great as the square meter area within urban urban areas. Part of the resistance to acceptance of the greenhouse effect is that it depends on what is essentially a trace gas, Carbon dioxide. All the trace gases amount to only 1% of the atmosphere, and so it’s difficult to see how that can change planetary climates so drastically. But if you add in the increase in insolation/decrease in albedo caused by urban heat islands, deforestation, and highways, then it begins to make the phenomenon more understandable.
Meantime, it’s late in the season now; winter is going to be similar to what I measure in the mornings, temperature differences of only 5ºC or even less. I will plan on putting up a series of perhaps 5 panels in the spring using mirrored plastic rather than the off-white translucent plastic I’ve been using. I began with this because it was cheap and I already had it on hand. It has done one thing, given me preliminary measurements to serve as a baseline while I attempt to improve the efficiency of the panels.
