Grounding planes across Europe 'could lead to

[Still Waters]

Temperatures in Europe could rise as a result of planes being grounded across the continent, according to research.

A study conducted after commercial flights were grounded for three days following the September 11 terror attacks found the average daily temperature range in the U.S. rose markedly - exceeding the three-day periods before and after by 1.8c.

Scientists claimed this showed that clouds formed by the water vapour in the exhaust from jet planes have a small but significant effect on daily temperatures.

I'll let Mattshark handle this one. He and I had a short conversation on the possibility of artificially inducing clouds as an anti-GCC measure. I'm not quite sure we came to any conclusions, but he'd know a bit more of the science than I would. I will say, if this study they mentioned is accurate, it does look up for the notion of generating clouds as global coolants.
