The real danger that you and most people overlook are the consequences of hundreds of Thermonuclear bombs exploded in the Ocean form the fifties to 1996. This series of events changed the Climate and destroyed many ecocsystems in the Ocean destroying the diversity. It is the phytoplankton in the Ocean that determine life on Earth more so than anything on land. Only recently has the phytoplankton begun to recover and if unmolested by oil spills and further nuclear waste, we may survive. CO2 will only let phytoplankton grow faster. You have been duped. The guilty ones have got one over on you. Even now they say nuclear war can Cool the planet. At first it may Cool the planet but with the phytoplankton gone the bacteria will take over and it will go back to the PreCambrian age. These NUKE people are very clever.
