You don't have to mark your ballot, and even if you did, that would require them to check your ballots before you dropped it in the box, which they don't do.

You can drop in a blank ballot, draw a penis on it, or whatever you like; if it doesn't follow the rules it's called "informal" and not counted.

What you're describing is still quite common - it's called the donkey vote (numbering the ballot from the top), is a valid vote, and actually gives the top candidates a slight edge.

500 kw/h per day is even more nonsensical. Energy over time cubed?

Maybe they meant kWh per day. That would almost make sense, but come on... it's not hard to get it right the first time instead of leaving people to guess which errors were made to infer the right value.

There's only about a kW of solar power available per square metre, and solar panels aren't anywhere near 100% efficient, so it can't be the output of the panels.

This is why it's bad to have the scientifically illiterate writing articles - they mangle the units beyond recognition so you have absolutely no idea what they're talking about.

As I recall, the heat forcing of CO2 is something like 5x that of a standard diatomic gas, ie N2 or O2, which make up a huge fraction of the atmosphere. When I ran this calculation before, CO2 was only barely a net heat forcer in the absence of water vapor. Including water vapor it slightly reduces the heat forcing of the atmosphere.

You recall incorrectly. The radiative forcing of the top three gases in the atmosphere - N2, O2 and Ar - is precisely zero as can be demonstrated from symmetry.

Argon is monatomic and therefore has no vibrational or rotational modes. N2 and O2 are symmetric about the centre of their bond, so their vibrational and rotational modes do not involve an oscillating dipole and therefore are not infrared active.

Radiative forcing comes down to infrared absorption of outgoing heat from the earth - if there is no infrared absorption, there's no radiative forcing.

I agree that 84% ( is not unanimous, but it's getting closer every year.
Unless, ofcourse, you count the opinion of people who don't understand the science involved and blame other people for their own lack of understanding.

Like the EPA?. Tell me if you can spot the huge logic hole in this statement:

Methane (CH4) is a greenhouse gas that remains in the atmosphere for approximately 9-15 years. Methane is over 20 times more effective in trapping heat in the atmosphere than carbon dioxide (CO2) over a 100-year period

Remember, these are the people writing policy and regulations concerning our rights with respect to climate change.

I think you made the point better than the parent to your post ever could.

You don't understand the science, so you call it a logic hole. In fact, if you think that's a logic hole your grasp of logic isn't too crash hot either.

From the latin vacca, or cow.

Because the first steps towards a smallpox vaccine were based on the realisation that dairy workers who had contracted cowpox were immune to smallpox. Vaccinia is very closely related to cowpox, but has diverged from it slightly since the its widespread use as a vaccine.

Because it was so successful as a vaccine, the name vaccination stuck.

Miss that part of the story, and it's nowhere near as interesting.

There's a good reason for that. I didn't attempt to present an argument to ban sales of iPhones. You well and truly missed the point.

"Merchantable quality" is a phrase that comes up in warranty law here, in that it if it fails before it's reasonably expected to, it's defective and the consumer deserves a refund. How you got "ban sales of iPhones" from that is a mystery to me. Grandparent is right - if "shit happens", it should be Apple's problem, not mine.

If you think Apple products only ever fail due to user error, the Reality Distortion Field is alive and kicking.

Warranties are also supposed to cover defects that materialise after some time and are not apparent at purchase.

Here in Australia, the law covers how long the item is reasonably expected to last, given its cost and quality. Given that the phones are often sold with two year contracts, the one year warranty is certainly deficient from that perspective. Having had two iPhones fail between the one year warranty and the two that should apply, I'm not too pleased about Apple dodging their responsibilities under our warranty law.

A $1000 phone that only lasts 13 months can't really be considered of merchantable quality, regardless of how quickly the industry progresses.
