I was very disappointed with this series as it had many problems relying on situations that were unrealistic.  First it assumes that ALL the moisture from the comet descends to earth as rain when in reality much of it would fall as snow and in arctic and antarctic regions as well as higher mountainous regions the snow would lay on the earth forming glaciers that would last thousands of years if not millions.  Additionally all the additional cloud cover that would result from the moisture in the atmosphere would create a global cooling effect expanding the arctic regions as well as ice packs.  Sea levels would rise, but at a much slower rate than this series proposes and an ice age would ensue. Secondly the idea that the ice in space surrounding the earth would stop rockets makes the assumption that the rockets would be along the equatorial regions where the ice ring exists.  Areas farther north or south would be relatively clear of these particles and rocket launches could make it from there go on out beyond the range of the ice and the reflectors would work from there.  I was most disappointed with this episode, it was not well thought out and assumptions made were more for dramatic impact than for accuracy.
