sunrises and sunsets.....

.....should become more spectacular here in the very near future thanks to the Icelandic volcano that is snarling European air traffic. I'm looking forward to seeing some beautiful skies.

Well, Iceland's carbon footprint sure has been shot to hell.

How so?

"As the volcanic clouds are carried a large distance by high winds, the sulphur dioxide will react with the atmosphere to form 'sulfate aerosols', say scientists. The ash and these 'aerosols' have the effect of scattering the sun's rays so only longer light waves make it through the atmosphere, which makes the sunsets appear ruby red.

Volcanic ash can also create the appearance of a blue moon, if the particles are the right size (experts say that means one millionth of a metre or a micron).

However, ash thrown up into the atmosphere usually contains a mixture of particles with a wide range of sizes, which tends to scatter blue light so a reddish moon is more likely."

it's just going to take a few more days for it to spread over the US.
