Have you ever tried to imagine the size of the universe? How about the number of flies in the world? Now try this. Imagine how many messages and emails are floating around in our atmosphere looking for a phone or computer to appear on. Some of them are there for days waiting for a phone to come into service and they must be everywhere at once because it doesnt matter where the phone appears the message finds it. Some of them are spam generated by computers to random numbers by the millions.  So my theory is that all those millions and millions of words and images floating around up there are acting as a blanket and not letting the planet cool down as much at night therefore starting off warmer in the morning resulting in higher temeratures during the day, hence global warming.
