To my knowledge, that's been disproven:
The number of interstellar dust grains increased from four per day, per meter in 1997 to 12 per day in 2000, Landgraf said. The results were announced earlier this month. He expects the rate to stay constant until 2005, and then increase by another factor of 3 prior to 2013.
What makes you think it's overlooked? Quite the contrary as a matter of fact, the effects of heat islands on localized heating as well as large scale warming are actually considered quite carefully. In fact, they don't ignore them. They look at them closely and have found that there is virtually no difference in temperature anomalies determined from rural locations and urban locations. Interesting though, that the greatest amount of warming is seen in the Arctic and other sparsely populated high latitude regions. Not a lot of socioeconomic activity in the Arctic. Interesting, the eastern seaboard (a hub of socioeconomic activity) has seen a cooling trend. Interesting that vast areas of the ocean show a warming trend.
Phage, something that I believe it often overlooked, but does have a very large impact is Urban heat island.
When hot dry air rises it becomes cool dry air and it does so at a rate dependent upon how hot it is in comparison to the surrounding air. The hotter it is, the faster it rises and it usually doesn't take long to reach a state of equilibrium where its temperature matches that of the surrounding air. Yes, you get thermals. No, they don't drift across the ocean.
Looking at the Prevailing Westerlies, this hot, dry air rises up from of China, mixed with fine particulates from manufacturing/power generation then could mix with cool, moist air over the Pacific and could explain weather anomalies on the West coast.
It's not really clear if hurricanes have gotten stronger but since they are powered by heat from the ocean, I don't think heat islands would have much influence.
Cyclic mixing action that takes place in the Gulf of Mexico from the Westerlies and Trade Winds could help explain why hurricanes have gotten stronger, as the Southeast has become very built up.
C02 is not the main culprit, water vapor is, but they cant regulate that seeing how the oceans are full of it.
Interesting though, that the greatest amount of warming is seen in the Arctic and other sparsely populated high latitude regions. Not a lot of socioeconomic activity in the Arctic.
Isn't the Artic warming trend more to due with O-zone depletion in that area rather than any connections to population?

Science has seldom been understood or held in the regard it deserves except by those who have an understanding of what it is (an is not). Science has never been without internal an external controversy.
