Which nations would most likely survive a full-out nuclear world war?
There are some points to clarify. (1) To break an atom it is needed a particle accelerator like the CERN. It has 151 Km in perimeter, full of giant electromagnetic coils, sensors and so on. (2) When the atom is braked by a proton at the speed of light, small particles spread in the particle’s detectors, nothing like an explosion or a chain reaction ever took place.(3) “Atomic” bombs are just dirt bombs. What kills is the long lasting contamination of water.(4) The contamination spreads and cannot be reversed back in time. It is an irreversible phenomena.(5)Given enough time all living tissue will be contaminated.(6)If the radioactive pollution passes a small level, organisms die because neutrons break macro molecules.(7)Dead contaminated tissue affects all the food layers, bacteria can’t clean it.(8)A 1000 years is an optimistic horizon for life to last, some fish in the abyss may last. However only to be contaminated later. The half life of the uranium 235 is about 700 million years, and you will need to pass several half-lives for the earth to be clean.(9) When a radioactive isotope decays it also decays in a less heavy radioactive isotope, creating more radioactive lighter garbage. That chain should have been kept underground, but who may ‘clean’ the water if there is no people alive beyond the year 2500 ?
Has Jamaica ever received snow or flurries on its highest mountain?
No Jamaica's Blue mountains are only 7402ft/2256 m,so no flurries or snow would be possible,it would have to be a colder than usual year,like 1975 with Florida i think. Yes ice has been dug from the summit of the mountains peak, and temperatures are known to have dip below 40 F / 4 degree Celsius with light frosting being observe in some years of the winter season when Cold fronts/ the tale ends of these systems influence weather activities in the northwest Caribbean region,this is why if you go up there you should bring a water proof jacket to keep you warm,and also from torrential rains which can last for a few minutes as well as days,also note it is Jamaica wettest area some 300 to 400 inches fall there as much as a foot at nights can happen,over on the north eastern face of the mountains Another place that temps can drop as low is Christiana located in the north of Manchester,were it has also recorded temps of 40 F/ 4 d-C. And yes it has hailed in some sections of the island like Portmore in 2005 mid March were there was reports of damaging wind and hail in the sunshine Municipal.
