Sea level has been going up ever since tide gauges started measuring it early in the 19th century
Doesn't have anything to do with a warm-up. Of course the water has to be coming from somewhere,
probably the ice caps in Greenland and Antarctica. And you know what? it's so cold in those places
that it never gets above freezing hardly anywhere hardly ever. Ice loss is a function of snow fall and
calving of bergs. The cause and effect of those two events are separated in time by years, decades,
centuries maybe even millennia.
Hardly ever doesn't mean never. Here's link to
Nansen Falls in Antarctica The link says it's an
impressive 130 meters wide. But the IPCC tells us that the surface ice mass balance in Antarctica
contributes negatively to sea level rise. Here's Table 10.7
from the IPCC's
AR4 report page 820 that shows that negative contribution for all scenarios. That doesn't mean
Antarctica isn't losing ice, it's just not from surface melting. Climate scientists are telling us that it's melting because
warm ocean water flows beneath the cooler surface water, flows beneath the sea ice, flows beneath shelf ice and then
melts the ice at the grounding line and then flows upwards and back to the ocean. Here's a graphic of that:

And of course that "circumpolar deep water" is warm due to CO2 blah blah blah...
My B.S. meter started beeping on that explanation about the time they talk about deep water warm enough
to melt fresh water ice.
I'm not saying that ice bergs calving into the sea don't exceed the amount of snow that falls; I'm saying that
temperature doesn't have anything to do with it. And banning fossil fuels isn't going to stop the trend.
