And your response now to my calling you out for posting spam... is to spam a different topic with unrelated garbage? Are you even sentient? Or are you just so scared of being called out that you hope if you try to harass me, I'll go away? [Rujiel, 2015-01-02]

You didn't call me out for posting spam. You repeatedly told me to kill myself. There's a difference. Once again:

Look, all this isn't remotely believable. You clearly compounded that account's massive spamming attempts by needlessly quoting obscenely huge chunks of his nonsense. [Rujiel, 2014-12-28]

Needlessly? How else should I debunk his baseless claim that I was "rude and insulting" when Jane/Lonny Eachus was actually just projecting his own obscene insults onto me? And if you have a better approach in mind, why not just suggest that better approach rather than repeatedly suggest that I kill myself?

Are they hiring you losers while still in high school these days? The bar for paid oil trolls sure is a low one--any stupid thing to prevent the discussion of the oil cartel's impunity. Do the world a favor and kill yourself. [Rujiel, 2014-11-20]

He's a paid shill and so are you--no amount of verbose whining on your part could hide the role of spamming you were playing in that thread. [Rujiel, 2014-12-28]

Once again, Rujiel accuses me of being a paid oil shill. But once again, why would the oil industry pay me to debunk the same baseless accusations they're helping to spread? I've been debunking misinformation about climate from Jane/Lonny Eachus and many others for 5 years now. Again, why would the oil industry pay me to do that?

Really? Among other things, I've contributed open source software to estimate mass changes on the surface of the Earth using GRACE satellite data. Here's my dissertation which explains the methods. Does that count for anything, or should I kill myself?

Your response is akin to someone who has just spent the last hour rolling in his own shit and flinging it at passers-by, standing up all at once and asking the surrounding crowd what's wrong. You're seriously so bad at this. Even your employer would be better off if you killed yourself. [Rujiel, 2014-11-30]

I cited Llovel et al. because of their conclusion regarding the deep ocean. I have already stated what research I would have to do before I could responsibly make a claim that the globe was warming. [Jane Q. Public, 2014-11-25]

No, you stated this:

... One thing I would have to check, just for example, is what those confidence intervals are given the multidecadal variability, which is not -- at least not uncontroversially -- known to any precise degree yet. What has been claimed to be a newly discovered variability in the Atlantic has turned up, for example. Not to mention that we know during La Niña periods of ENSO there tends to be storage, while during El Niño, more of a release. All these factors would need to be considered. Until I do, I neither agree or disagree. [Jane Q. Public, 2014-11-24]

Jane, that's not research you'd have to do before claiming that the globe is warming. You'd only have to do that research before attributing the warming to a particular cause. The only research you have to do before claiming that the globe is warming is to read the last sentence in the Llovel et al. 2014 abstract, and ask yourself if the bottom edge of their confidence interval is positive. Is it?

I cited Llovel et al. because of their conclusion regarding the deep ocean. I have already stated what research I would have to do before I could responsibly make a claim that the globe was warming. [Jane Q. Public, 2014-11-25]

Once again, the Llovel et al. 2014 conclusion regarding abyssal ocean temperatures depends on the globe warming. I've already explained why. If you didn't understand the equations I wrote down, just ask for help. Once you understand those equations, you'll finally see why you can't cite Llovel et al. 2014 regarding abyssal ocean temperatures while also claiming that the globe isn't warming.

I have frequently been astounded by your ability to find past information that suits your purposes, but when it comes to information that may serve to contradict your position, you suddenly appear to have never heard of Google. It is SO ridiculously easy to find references to issues with GRACE that I'm not going to bother to do it for you, and only an idiot would call that confirmation of a contrary position. [Jane Q. Public, 2014-11-25]

Sadly, that's exactly the response I expected.

I've written about many issues with GRACE, and released my source code. Here’s a quick link to browse the “control panel” of my code, followed by the top level of the program itself. All the functions used in that file are declared here and defined in full here.

So Jane will have to be more specific. I've written about many issues with GRACE, but none that qualify as "rather huge problems".

Past experienc

You should ask about the magnetic poles and if increasing/decreasing magnetic fields effect gravity at all? Do they take into account the magnetic fields? And if solar storms impact the larger magnetic field outside the planet... Or are they just detecting mass levels?

GRACE just detects mass; solar storms are a source of noise because they exert non-gravitational forces on the satellites which need to be subtracted to analyze the gravitational forces.

My question is if the melting arctic ice cap will impact the mass up there and will cause a change in the gravity?

Since GRACE only detects mass, it can't tell the difference between floating sea ice and the equivalent amount of water displaced by the floating ice. So GRACE can't see the melting Arctic ice cap, but it can see thinning glaciers and ice sheets when the meltwater flows into the ocean because in that case the mass moves.

Does warmer water in the summer weigh more or take up more volume?

Yes, this is called the thermosteric effect; I mentioned annual variations in paragraph 13 of my 2011 paper. Satellite altimeters like JASON and TOPEX/Poseidon can measure sea level rise due to thermosteric effects, but they also measure the sea level rise due to added water from thinning ice sheets and glaciers. Because GRACE can only measure the mass of the added water, it can't measure sea level rise due to steric effects (temperature and salinity). Ironically, this means we can solve for steric sea level rise by subtracting the GRACE estimate of sea level rise from the altimeter estimates.

If snow is less dense than ice (mostly), can you tell where the glaciers are melting and not recovering after the winter?

Not with GRACE alone, but (as with steric sea level rise) satellite altimetry can provide volume measurements. Of course, if the meltwater drains far away from the glacier, GRACE alone could see this change in mass. And, in fact, GRACE is observing this all over the globe.

I've tried to solve for the Earth's nearly-diurnal free wobble, but it yielded a map that looked suspiciously like the mass trend. I think this happens because the NDFW's frequency is similar to that of the K1 tide, which experiences aliasing in the GRACE data as discussed in section 4.4 of my 2011 paper. So... no.
