How many cubic miles of silt do the world’s rivers dump into the ocean every year?
Just curious.
Not just the world’s rivers depositing sediment into the oceans, but erosion of shorelines, underwater volcanoes, oil seepage, etc. that all contribute to an increase in ocean levels that never gets reversed or accounted for in these climate predictions.
Good question. Natural erosion is always moving sand/mud downstream into the oceans. This might be offset by the amount of rock and volcanic material from the movement of tectonic plates and volcanoes but I'm guessing that erosion wins out overall.
