Unless you use multiple systems (with synergy) side by side. That makes any panel on the screen side a nonstarter.

So the carbon that you "sequestered" is returned to the atmosphere.

What happens with your body after you die?

What will happen with the sugar (which is where the carbon ends up)?

What happens with the food that you ingest?

That would mean returning it to the atmosphere.

What will you do with the carbon that the plants sequestered? Especially so that it won't rot and be returned to the atmosphere?

Yup. "How much does it cost compared to other methods of generating energy?" is the question. And the answer is "More than solar and wind, making coal uncompetitive."

Not if you make lots of money from selling the polluting stuff.

Why do we need to free BSD and why did (s)he get incarcerated?

as anyone who watched World War Z can confirm.

After it was uncovered it should have slowly risen by itself, like Frankenstein's monster or a Zombie. This was boooring!

Unless the product has been certified for use with classified information, that's not much of an assurance. The government has its own internally-developed tools -- which presumably it has confidence in (SIPRNet, etc.) -- for protecting information that it deems sensitive. The NSA might well decide that subverting a commercial tool is worth the risk of compromising something that's used by the government, but only in relatively trivial ways.

I don't know enough to impugn Zimmerman et al, but I don't think "it's used by the government!" is necessarily a great seal of approval, unless it's a formal certification (e.g. NSA Type 1 listing) saying that it can be used to protect classified information. And I'm not aware of any COTS software products that are on the Type 1 list; the NSA only approves particular hardware implementations (at least that I've seen, though I'm happy to be corrected although I'd be surprised).

First of all, we're tracking at or above the A1FI scenario (the worst case considered) and there's no sign of changing that.

Secondly, the IPCC has always been very conservative. Many scientists say that 2m/6ft is what we'll see by 2100 and a few (like Hansen) even predict much higher numbers. Also, sea level rise won't magically stop in 2100.
