Rainy weekends are all our fault.

New Scientist adds insult to injury by telling us that not only does it really rain more often on our days off, but that our work week is to blame:

Evidence has been mounting over the years that the weather in certain parts of the world, including the US, Japan and China, can be driven by the weekly cycle of human activity. This is because we tend to produce more air pollution during the week and less at the weekend. Evidence that such an effect occurs in Europe is controversial and has been harder to come by.

All the smog comes down some time.
