Global warming and possible positive feedback mechanisms?

B & D are the most likely from rising temperature's. Warm water releases co2, cold water absorbs co2, you obviously did not take chemistry or basic science in grade school. Also there is a greater variation between high and low tide than there will be in sea level over the next couple of hundred years. the panic spreaders ume the people reading their alarmist rhetoric know less about science than they do. this is not always true and this is why there are skeptics that have learned the science to joust with the warmers.
