I don't usually reply to ACs but this level of stupid needs a rap on the knuckles. You do realise that covering a single digit portion of the uninhabited sections of the Sahara desert with inefficient old PV cells could supply enough power to satisfy the needs of the European Union right? We haven't even BEGUN to tap into the potential of renewables.

And before you start paddling your keyboard about how the sun goes down at night, rap yourself on the knuckles and think.

Or instead of descending to outright misanthropy we could look at the political climate and situation in Rome at the time, where lots of citizens lived largely on state handouts and whose main entertainment was the Colosseum, bread and circuses. Bored and indolent, they needed continually escalating spectacles - they actually flooded the Colosseum and lifted ships in to do battle, naumachiae - so is this period in Roman history a warning about meaningless lives lived without industry, Roman culture, or human nature?

I don't care what you say. Read even further down would be my advice, or just read the bit I quoted again: "Broad regions of the Earth experienced almost synchronous changes over periods of 0 to 30 years (Severinghaus et al., 1998), and changes were very abrupt in at least some regions (Bard et al., 1987), e.g. requiring as little as 10 years off Venezuela (Hughen et al., 1996)." It's well known that sudden temperature increases and decreases have happened with some regularity in recent history, geologically speaking. Well known by those who care to actually learn the science, of course.

That moment when you realise you're as ideologically hidebound as any denier.

the largest single temperature spike in the past 45 million years.

You mean larger than this: http://www.ipcc.ch/ipccreports...

The central Greenland ice core record (GRIP and GISP2) has a near annual resolution across the entire glacial to Holocene transition, and reveals episodes of very rapid change. The return to the cold conditions of the Younger Dryas from the incipient inter-glacial warming 13,000 years ago took place within a few decades or less (Alley et al., 1993). The warming phase, that took place about 11,500 years ago, at the end of the Younger Dryas was also very abrupt and central Greenland temperatures increased by 7C or more in a few decades (Johnsen et al., 1992; Grootes et al., 1993; Severinghaus et al., 1998). Most of the changes in wind-blown materials and some other climate indicators were accomplished in a few years (Alley et al., 1993; Taylor et al., 1993; Hammer et al., 1997). Broad regions of the Earth experienced almost synchronous changes over periods of 0 to 30 years (Severinghaus et al., 1998), and changes were very abrupt in at least some regions (Bard et al., 1987), e.g. requiring as little as 10 years off Venezuela (Hughen et al., 1996). Fluctuations in ice conductivity indicate that atmospheric circulation was reorganised extremely rapidly (Taylor et al., 1993). A similar, correlated sequence of abrupt deglacial events also occurred in the tropical and temperate North Atlantic (Bard et al., 1987; Hughen et al., 1996) and in Western Europe (von Grafenstein et al., 1999).

Hold up there. Climate has been changing since we first had some. The big question is "how fast?", and the current changes are very rapid. A few kilometers of ice go away over tens of thousands of years, that's natural. A variation of 2C over a few million years, that's natural. A variation of 2C in a century or two is remarkable, on a geological basis.

Not really, no. http://www.ipcc.ch/ipccreports...

Moreover, if we could reverse AGW, and prevent human impacts on climate, we wouldn't be keeping the climate static. We'd be keeping it pretty stable over millennia.

You realise you just said, "we wouldn't be keeping the climate static, we'd be keeping it pretty static over millennia".

The current rise in sea level is a little under 3mm per year, which puts us up close to a foot by the rest of the century. That's going to be significant in some respects. Storm surges will be almost a foot higher, and stuff that's on the beach close to the highest high tide mark is going to start getting wet. However, the increase seems to be accelerating, and there's no reason to think it won't be two feet or more by the end of the century. I wouldn't count on centuries before significant rise.

Wiki says 21cm to 34cm by 2100. It's really not an incipient threat, which is why we'd best start making longer term plans for adjusting to it, for ourselves and the other inhabitants of this blue marble. And once again we don't really know how everything fits together so the acceleration might not be constant. It might get worse of course but it's all speculation at this point.

No. it isn't. As a scientist I can firmly conclude Global warming is happening, its caused by human activities, and we need to stop it as it contributes to an array of very devastating consequences.

Hold up there a minute mister scientist, where I'm sitting at the moment was buried under a few kilometers of glacier a hundred thousand years ago, and humans didn't contribute a thing to the sequence of events that caused it to melt. We are in a perfectly natural interglacial, something that's happened before. That's not to say human civilisation isn't contributing to climate change but what's up for debate is just how much of a contribution we're making.

Secondly I find the notion that we can just stop the earth's climate from changing quite suspect - it's not stable or in equilibrium and never has been, with a few possible exceptions. A nudge in the wrong direction and we might find ourselvs back in an ice age, and if you think global warming is bad believe me it doesn't hold a candle to global cooling. Maybe we want to warm things up.

Either way the situation is going to change, so it seems as though the best policy would be to preserve as much biodiversity as possible and ready ourselves for flooding and so on. Not anytime soon mind you, even the worst realistic predictions of sea level rise give us centuries before we start to see significant changes. As things stand I can see all fossil fuel energy sources being phased out by the end of this century, and I fully expect to see widespread adoption of electric vehicles within my lifetime, so it's not so bad. Devastation is going to happen and has happened many, many times in the earth's history, long before humanity made an appearance, but we can minimise it this time round.

And even if we stopped all emissions right now, as far as I'm aware the earth will continue to warm anyway, so perhaps the minor effects of a century of declining emissions versus causing economic chaos right now are a pretty good tradeoff.

That's like saying someone can go out and write books, get them published and sell enough copies to make a decent living doing it.

Who said anything about making a living doing it? How about making what you can doing it, a pursuit aided not in any way by piracy.

I have a family member who is preparing to release a book at this very moment. Her literary agent's first action was to put together a marketing team to promote the book in order to grease the wheels in selling the book to a publisher.

Great, my maiden aunt is a kung fu ninja. Even if some very unusual literary agents organise marketing teams you can bet your ass they aren't doing it out of their own pocket.

Are you really one of those mindless idiots who jumps on the cock of the media conglomerates and believes that every connection to a torrent swarm is a lost sale?

Who really cares, stealing from authors in one way or another is as low as it gets.

One of the first books I got for free was a the first piece of Twilight fan fiction from an unknown author on Smashwords who was certainly not a well known, filthy rich author at the time. The book wasn't my cup of tea, but it seems to have worked out fairly well for the author.

Right, so now book piracy is actually helpful. Are there any further moral pretzels you'd like to wheel out, inquiring minds want to know.

The problem is that everyone works from the assumption that capitalism is mandatory.

Just so I've got this straight, you're using a story about how a middling hard leftist legal system and business environment wiped out an open source company to take a poke at capitalism? Good job, and modded up to 5 no less.
