The summit greets us with a vista arranged from snow and ice, water and clouds.

In China, they use artillery shells, rockets and airplanes to spray existing cloud systems with silver iodide, a compound that triggers moisture in the clouds to form ice crystals, which then fall to earth as snow or rain.

Dr Solomon discovered that chemical reactions destroy ozone on surfaces such as the ice crystals within high-altitude 'polar stratospheric clouds' as well as on other atmospheric particles high in the atmosphere.

Therefore, it is intriguing that the bacteria and fungi best known for their ice-nucleating ability are also famous for their tendency to frequent clouds.

Ice can form on airplanes when temperatures are near freezing and there is visible moisture, such as clouds or rain.

The question then becomes, well, what happens then: when the ice melts and albedo lowers, when warmer weather and higher CO2 increase plant growth, what happens to clouds and so on through a list of hundreds of possible feedbacks.

Depending on the capricious whims of the extreme Arctic climate and calendar, thick clouds reveal remote fragments of the landscape as if concealing some great mystery, blinding sunshine illuminates the ice, or perpetual moonlight bathes it all in the strange, blue half-light of the polar night.
