From the article, regarding sea level rise: When ice shelves lose large chunks, it does not raise sea level because these bodies are already afloat. However, the loss of an ice shelf can speed up the seaward flow of the nonfloating glacial ice behind it, and this ice can in turn contribute to sea-level rise. Researchers have estimated that the loss of all the ice that the Larsen C ice shelf currently holds back would…

The faster that levels rise the sooner we are to get off our collective asses and make a difference.

You realize poor nations will get fucked over disproportionately, right?

If we took a fleet of tug-boats and towed this ice to the Middle East, I wonder how long the fresh water would last?

... Make a difference for the generation after the next. Maybe.

True, but the longer we have to sit on our asses, the more likely we are to succeed in our effort to make a difference when we finally get around to it (due to technological progression).

I wouldn't count on this - markets don't seem to care about sea level rise at the moment

Reinsurance is definitely concerned about sea level rise. Here is an example presentation from SwissRe showing their estimates of the increasing damages due to climate change (e.g., slide 7).

Let's see how terraforming this one works out before we go off terraforming another.

Might be better to terraform an already messed up planet before our own. (which is arguably somewhat messed up, but not Mars-level. Yet)

I think the parent's point is that we are already currently terraforming our planet, whether or not we would like to admit it.

Does anyone know where I can find estimations of sea level rise over the next 10 to 200 years? I always hear horror stories of 20 meter rises but don't know what the ranges of "consensus" are...

The Wikipedia page is not a bad place to start. It links to a quite a few external resources in the Projections section.

> "I have spent so much time now looking at the satellite images, and I really love this ice shelf, it would be such a tragic thing to see this thing go." Reminds me of Kim Stanley Robinson's Mars trilogy. We humans can fall in love with large chunks of ice just by looking at them long enough. How will we ever bring ourselves to terraform another planet?

Why is it so important that we terraform other planets? Is it really a desirable thing to spread across the solar system and beyond like mold on stale bread?

You don't experiment on your production planet. Mars could be a decent staging planet!

In software, the testing environment usually isn't more expensive by several orders of magnitude.

Well, it’s important to the mold.
