Submission + - SPAM: Watching-Grass-Grow.com upgrades to new webcam 1

xmas2003 writes: The Watching-Grass-Grow.com website has been providing an "exciting" view of a front lawn for over a decade. The webcam is being upgraded after 7 years so you can now view the grass in crystal clear HD — use the alternate views to see the dramatic improvement. Mr. Grass reviewed various cameras and says "Maybe in a couple of years, I'll upgrade to 4K ... or even 8K ... so you can see individual blades of grass! ;-)"

Right, replacing infrastructure which can output a predictable amount of energy 24/7 with power sources which fluctuate massively depending on environmental conditions ... that doesn't change anything at all.

We're replacing it with a power source that doesn't make environmental conditions fluctuate, moron.

Any polyatomic gas is a greenhouse gas. If it's airborne and has three or more atoms, it qualifies.

Low energy infrared photons (like those emitted by a body at 300K) can cause bonds to bend side to side in a flapping motion.

Oxygen and nitrogen are diatomic molecules. They can stretch, but there's no way they can bend because there are only two atoms. So they're transparent to IR emitted from the ground and are not greenhouse gases. Molecules that can bend need three atoms or more, like carbon dioxide, which gets hit by an infrared photon and moves like a bird flapping its wings before reemitting it. H2O is also a greenhouse gas but its long term atmospheric concentration is stable over the long term and doesn't rise year over year. Methane is a potent gas because it's tetrahedral and its single bonds are easier to flex than e.g. the double bonds in CO2.

HFCs and CFCs also have tetrahedral shapes with single bonds, but they're more potent greenhouse gases than methane, because the fluorine and chlorine atoms distort the charge concentration and give the molecule a dipole moment that makes it better at scattering photons. They also provide it with more possible bending motions.

I'm not sure why this article is talking about illegal fluorotrichloromethane being a greenhouse gas. It's illegal because it destroys stratospheric ozone. Gram for gram, sarin is an extremely potent greenhouse gas, but that's not why it's illegal.

The article is poorly written. Yes CFCl3 is a potent greenhouse gas (and so is ozone actually), but the issue here is the ozone destruction, not the greenhouse effect. One shady factory in China manufacturing CFCs will warm the earth about as much as the factory next door legally manufacturing HFC. Sarin is a greenhouse gas too, but that's not what makes its release newsworthy.

No, it's not natural. CFC-11 is fluorotrichloride, or CFCl3. C-Cl and C-F bonds are artificial- in nature you don't see them much. To form them you need to invest energy, because you're starting with ionic chlorides and fluorides, which are not terribly interested in forming covalent bonds with a non-metal like carbon. That's why these chemicals fall apart so easily when they reach the upper stratosphere. The fluorine doesn't stick around for long, but the chlorine with the unpaired electron attacks ozone and survives the encounter. A single chlorine radical will destroy billions of ozone molecules for the two years it spends in the air. It attacks its first ozone to form ordinary oxygen and chlorine monoxide, which still has an unpaired electron. The chlorine monoxide attacks a second ozone, yielding more oxygen and releasing the chlorine radical to kill again. Although the chlorine radical itself only lasts a few decades, its fluorotrichloromethane precursor hangs around for decades to replenish the supply.

The fact that the molecule has four of these weird bonds makes it really suspicious. Someone is definitely making this shit.
