Any of these will do far more to contain rising sea levels than all the cockamamie schemes of trading carbon credits, storing carbon dioxide underground or all the other goofy suggestion of the global warming crowd which stands to be enriched and empowered by such schemes.
CO2 is not harmful, nor does it determine the temperature. If anything, rising CO2 levels are beneficial.
Sea levels are not rising, either.
All of their models and projections are wrong because they are based on a flawed theory.
The source of all heat on earth is responsible for the temperatures. When the Sun gets less active, the Earth literally freezes. The current interglacial period has lasted longer than usual. If we want to worry about climate change, start planning to survive miles of ice covering the upper midwest.
The entire Gore-bull warming scam is about money.
