Originally posted by seer View PostThat is an interesting thing. Since the industrial age do we really know how much the oceans have risen?
For instance, cities built only a couple thousand years ago along coasts can be found either submerged or miles from the present day shore. Ostia Antica, which was a port city connected to ancient Rome by a wall is now 2 miles from the sea. Troy was also described as being next to the sea but its ruins are now 4 miles away from it.
And of course some cities are now nothing but undersea ruins. One very recent example is the village of Hampton-on-Sea in southeastern England which finally went under in the early part of the last century. For a larger example there is the Egyptian city of Heracleion which was ancient Egypt's main port for international trade and collection of taxes but now is 1½ miles off that country's coast under roughly 33' of water.

Yeah, there are lighthouses that are now further inland and several that had to be moved away from the encroaching water - much of that measurable in the last 50 years.
It proves the shorelines change - but not why."He is no fool who gives what he cannot keep to gain that which he cannot lose." - Jim Elliot

Originally posted by oxmixmudd View PostYou'd have to look at how much CO2 is sequestered by that additional vegitation, vs how much is being input per year.
Bottom line, the measured CO2 content of the atmosphere is going up. monotonically. That value represents the sum of all the inputs to the atmosphere and all the processes that can pull CO2 out. We don't have to know what they all are to know that there isn't enough CO2 sinks to compensate for what is being put into the atmosphere.
So it is not enough.

Oh, so you just mean it isn't enough to balance the net rate right now. Not that it can't/won't be enough ever. At the very least, once there are no more fossil fuels (or alternatives become more economical than fossil fuels), then the input goes away, and the sinks would make the atmospheric CO2 decline, right?

If anyone thinks himself to be religious, and yet does not bridle his tongue but deceives his own heart, this man’s religion is worthless James 1:26
This you know, my beloved brethren. But everyone must be quick to hear, slow to speak and slow to anger; James 1:19
