...Chinese involves dosing the atmosphere with silver iodide, a chemical solution either dropped from planes or shot up from the ground. (Other methods use salt or dry ice.) The silver iodide particles supercharge cloud formation, as they act as excellent condensation nuclei. Once clouds form, they also start a positive feedback effect. As droplets freeze and are added to the cloud, they release their heat, creating an updraft which draws additional moisture from the ground into the atmosphere...
...publication of a study on Tuesday in the Proceedings of the National Academy of Sciences. Lead author Lonnie Thompson, a glaciologist at Ohio State University who has been to the summit of Africa's tallest mountain repeatedly over more than a decade, says that while the glaciers did start melting a century ago, their retreat has sped up dramatically in recent years.

After the moon colony is established...

Some classes start by asking for Class dues of $15.00 per year and increase them later as the ability to pay increases...
