The oceans maintain a constant balance of CO2. As CO2 increases, more of it dissolves into the oceans( only making the oceans more acidic and killing off all the fish eventually.). So, the ice caps are melting because the sun is pumping more heat( more light ) into the earth. The sun ,since 1974, is dragging the solar system into a "bubble" next to our milky way. The bubble is filling the sun's corona with extra plasma(many millions of degrees hotter than before 1974). Anybody who grew up in the '50s can see how much more brighter the sun is today. There are much more traffic accidents today, due to the blinding sun. There's been a worldwide increase of blindness disabilities. So "carbon credits" are a fraud ,since the little CO2 that humans generate has little effect on global warming.
