Deep ocean NOT Warming ,ocean holds No missing heat

Way back to page 1, it is great news that mojo now accepts GRACE satellite data as valid. Was not always the case. Important because:

Regional acceleration in icemass loss from Greenland and Antarctica using GRACE time-variable gravity data. I. Velicogna, T. C. Sutterley, and M. R. van den Broeke. Geophysical Research Letters 10.1002/2014GL061052

Abstract We use Gravity Recovery and Climate Experiment (GRACE) monthly gravity fields to determine the regional acceleration in ice mass loss in Greenland and Antarctica for 2003–2013. We find that the total mass loss is controlled by only a few regions. In Greenland, the southeast and northwest generate 70% of the loss (280±58 Gt/yr) mostly from ice dynamics, the southwest accounts for 54% of the total acceleration in loss (25.4±1.2 Gt/yr2) from a decrease in surface mass balance (SMB), followed by the northwest (34%), and we find no significant acceleration in the northeast. In Antarctica, the Amundsen Sea (AS) sector and the Antarctic Peninsula account for 64% and 17%, respectively, of the total loss (180±10 Gt/yr) mainly from ice dynamics. The AS sector contributes most of the acceleration in loss (11±4 Gt/yr2), and Queen Maud Land, East Antarctica, is the only sector with a significant mass gain due to a local increase in SMB (63±5 Gt/yr).

How much, where, and hints of acceleration (based on only a decade, so handle with care). Wonders of science. Evidence. All that stuff.

 

So, you did not ever here do the Ad Hominem on Velicogna? Good to know.

The GRACE ice dynamics I posted are only the most recent. Earlier show similar with less detail. Science improving our understanding of the world.

For the Antarctic ice melting on margins, one would need to read publications recently cited hereabouts. Probably others that I have not seen. But melt accelerations have nothing to do with climate and indicate perfectly targeted geothermal increases? Yeah well maybe, but doesn't that look like a stretch? Even to you?

I leave it to our readers to choose the better between my science-based idiocy, and mojo's fuller understanding from affinity websites. Personally I find his the more interesting, more brightly colored.

But interesting is one thing, and the concordance of evidence is quite another. The latter is boring, asking for mental effort. Yuck. I hope that mojo never stops posting interesting things here. Without that, my links to literature would be even more ignored than they are now.

So, as MentalFloss says, hit me again!

 

And what reference do you have for this? (Other than the very short satellite record we discussed a while back.)

 

Ice floats because the melted water is denser than the glacier made of ice.


The melt water should be under the ice:

Notice how the soot/dust appears on the surface. It is concentrated because the snow/ice it was on before has lost water that flows down the moulin.

There are additional details in the manuscript. So if y'all ever choose to get past the abstract, this might be a good time. Accelerating ice loss over the (not much more thana ) decade.

Ever more precise knowledge of polar ice dynamics (here one example) is the thing that merits your attention. If someone "responds" by saying "look, a squirrel"?

Ignore the squirrel.

 

Way back on page 1, we started from the idea that sea level rise is now about 3 millimeters per year. So, a foot or three this century, well how bad could that be?

If you live on a river delta, on not very much money, it could be bad. Can read about it here

BBC News - Major deltas 'could be drowned'

or even better in the linked article now in Nature (journal). The sediment supply rate is key. Deltas exist because they had this, but river impoundment upstream often interferes. If your river is among the muddiest, it can keep up with SLR. Otherwise, not so much.

"Over half the world's population live in flood plains or in deltas - that is why it is so important."
This is quote I'd like to explore. Flood plains can be very far above sea level, so that is a separate issue. Population on deltas themselves? Maybe half billion or a billion. Giosan presumably knows.
