I've been hunkered down writing a good bit of the day. There's also been some bill paying and air conditioner purchasing and installation mixed in there... we're pushing 100 degrees here in NC. I bought a 12,000 BTU model that's supposed to cool 550 square feet--roughly the area of my living room, office, and a bit of the kitchen. So far, the day is really testing the unit. Tomorrow, I'll install the much smaller 65000 BTU model in my bedroom and see if that helps things out. Days like today make me wonder if I'm wrong about global warming. But, of course, the data from any given city on any given day is pretty meaningless. And global warming is one of those issues where it really doesn't matter much if my opinion is right or wrong. So what? The reality is, we as a species are going to be pumping a lot more CO2 in the air next year, and we'll be pumping out more the year after that, and more the year after that. The AC unit in my window is making my carbon footprint bigger, but I'm one of the select few people on the planet that get to have AC. That's not going to last for long, though. The chinese are putting in AC. People in India are installing AC. Coal is going to be powering most of this.
And, of course, that's not even the big driver of greenhouse gasses. The big drivers are the agricultural systems that keep American's fat and happy... and, coming soon to a planet near you, steak-eating Chinese will make American's look like vegan sissies. Food follows money.
So, we're all doomed, unless we're wrong, and there are feedback systems in the planet that keep the thermostat stable, or unless the extra heat turns out not to matter all that much. The ice caps will melt, and we'll lose some tropical shoreline, but we'll start building beach houses in Russia and Canada, and life will roll on.
This wasn't at ALL what I sat down to talk about by the way. I'm actually sitting down to report that at some point tomorrow, I'll roll over the 120k mark on Dragonseed, the third Bitterwood book. Actually, there's a decent shot I'll roll past the 125k mark. I worked on Chapter 29 today. Tomorrow I'll do 30, and maybe go back and fill in a scene or two, and that will be the end of the first draft.
Right now, I'm in a good news/bad news sort of area, plot wise. I had really set myself a goal of finishing all the major plot threads raised in the trilogy at the end of this book. Any further books set in the Dragon Age were going to follow a different cast. But, while I'm confident I'll end the story of Bitterwood, it looks like I'm going to have to leave a few of the rest of the cast with some dangling plot threads. Not major ones, but my goal had been to have all the characters by the end of this book either living happily ever after, or dead. Now, it looks like I'll be getting many of my characters out of the fire at the end of the book, but still in a frying pan, so to speak. Ah well. These things happen. Rome wasn't built in a day, and the human/dragon struggle for dominance can't be completely resolved in a few books. It's like waving a magic wand and saying that the Palestinian/Isreali conflict is all better now.
Sunday, I plan to nap. Maybe go fishing, even with the heat. Maybe stretch out in front of the AC and read a book. Then... the rewrites begin. But, that's the thing about endings. They always seem to morph into beginnings.

Atom-huggers
Okay, in my last post I came out as a global warming skeptic. However, here's some good news for those of you who worry about our carbon emissions: we have a safe alternative that produces no greenhouse gasses.
I've been googling this evening trying to find the total percentage of American carbon dioxide output that comes from coal. Unfortunately, I'm finding wildly varied numbers--anything from 35% to 85%. I can't believe the internet is giving me fuzzy information!
Whatever the actual figures are, I can tell you this: your house has a bigger carbon footprint than your car. We think of electricity as "clean" energy. If you have an electric furnace and an electric water heater, stove, etc., you might feel pretty smug about the fact that your house has no chimney. In fact, though, most electricity in America is generated by burning coal, and the emissions from that coal equal far more carbon than is being put out by all the automobiles in the US. Again, I keep finding different numbers--as low as 9%, as high as 25%.
We can't all stop driving in the next decade. If we switch to electric cars that are recharged at home, we'll be pushing the pollution from a tailpipe to a smokestack, but if we're still burning coal, it does little in the long run to reduce CO2. And, even if we perfect the electric car, we aren't going to perfect an electric airplane anytime soon, and all those big trucks on the highway are still going to be rolling on diesel. Electric cars might make acceptable short range commuter vehicles, but we are a long ways away from having a battery that would propel an 18 wheeler five hundred miles on a charge.
Fortunately, oil has jumped to $120 a barrel and could go higher. (Fortunately if you believe in global warming, that is.) This means that price alone is going to change people's driving habits. And, I predict that as $4 gasoline sets in, you're going to see more and more cars in production that are real fuel sippers. The Honda Insight hybrid gets almost 70mpg. I predict we'll see a 100mpg commuter car hit the market within the next 5 years. Maybe that's overly optimistic, but right now you can count all your 50mpg choices on the fingers of one hand. Give it five years, and you'll need both hands and some of your toes, too.
So, higher fuel costs will eventually cut down carbon emissions from vehicles. But, as noted, this is, maybe, 25% of the problem. The big target has to be those coal powered plants that are currently the backbone of american electricity, and, thus, the backbone of our economy and our way of life.
The technology exists to shut down the last coal fueled powerplant within the next twenty years. We just need to get over our irrational fear of nuclear power plants.
A few posts back, I talked about American's inability to judge relative dangers. Nuclear power is one of the victims of irrational fears. Let me be blunt: Nuclear power isn't safe. People can die working in nuclear power plants. The nearby cities can be endangered by nuclear power plants. Nuclear power plants produce dangerous wastes. However: Every one of these statements is equally true for our present coal-based energy generation. Far, far, far more people have died mining coal than have ever died from nuclear power. US department of labor statistics show about 50 people die a year in mining accidents. Many more people die each year from a disease known as "black lung." Burning coal produces polution that some people estimates contributes to 10,000 cancer deaths per year, though I'm skeptical of such a round number. Still, it's inarguable that coal based power plants push a lot of bad things into our atmosphere... and, if you think that carbon dioxide is one of those bad things, then the environmental cost of coal is almost immeasurable compared with the environmental cost of nuclear. Coal also has pollution effects beyond just burning it... mining it currently strips away whole mountains and is a major source of ground water pollution.
The number of deaths attributed to nuclear power plant failures in the US is pretty low. The worst nuclear accident ever in America, Three Mile Island, killed exactly zero people. Yes, there is risk with this. If we converted to a completely nuclear electric economy, and had 1000 nuclear plants online instead of 100, we'd be increasing the risk of eventual catastrophic failure. But, again, you have to weigh this against the known risks and dangers of coal. Currently, if you compare the pollution and risk footprints of the 100 nuclear plants in the US against the pollution and risk footprints of 100 coal plants generating a similar amount of power, I believe you'd find that nuclear is the most responsible choice we can make for the environment.
As for waste, yes, nuclear waste has special challenges. There is a NIMBY response to its disposal. But, if you are a believer in man-made global warming, then you have to be more afraid of coal than nuclear. Nuclear power isn't going to make the oceans rise 30 feet. Carbon... maybe. I doubt it. But everything is a trade off of risks.
By the way, for proponents of wind and solar: Yes. Go for it. If you live in Arizona, solar may well be a better option than nuclear. If you live near an ocean or someplace that generates a lot of wind, put up the windmills. A windmill in my immediate vicinity would be mostly decoration... there's just not that much wind here. Solar panels are fine. We can cover the roofs of our nuclear power plants with them, but the technology isn't there today to have it completely replace coal. Nuclear power is ready. It's been ready for decades. It can save the world from coal, if we just have the good sense to use it.
Environmentalists are frequently called tree-huggers. Count me in the ranks of the atom huggers. I believe in power of the atom, by the atom, for the atom (at least when those atoms are arranged into the shape of me).

What would it take to make me change my mind?
I was at Ravencon in Richmond, Va on Friday and Saturday. It's a great con. Very well organized, good attendance, and I thought the panels had interesting topics. There were plenty of actual science panels to go with the writing panels and gaming panels, etc. As a science fiction writer, and a science geek in general, I like being in the company of people who know what they are talking about.
On Friday, I moderated a panel on Global Warming. I went into the panel well prepared to make my argument that the case for man-made global warming isn't the slam-dunk, no further arguement needed conclusion presented by folks like Al Gore. I anticipated being a lone voice of dissent on the panel, so I tried to gather as much data as possible before going into the room. Instead, out of about 30 folks in the room, it turned out that fewer than five thought that man-made global warming was a reality.
I was actually somewhat bothered by this. Anytime I find myself on the side of a majority opinion, an instinct kicks in that makes me start questioning my own beliefs. And, beliefs is the operative word here.
One of the panelists who doubted global warming kept referring to scientists she knew who thought that man-made global warming was BS, so, ergo, it was BS. But, while I like talking to experts, I dislike relying on faith in experts as a foundation for my beliefs. To me, this is more faith than reason. Plus, it leads to the standard media "news" treatment of dueling experts. "My authorities are better than your authorities" begins to pass as reasoned debate. People no longer listen to evidence--they listen to "leaders," and this strikes me as a risky way to run a world.
I'm human. I have limited time and limited resources with which to judge the world. On a lot of important issues, it really isn't reason that guides me, but gut. I suspect the same is true of most people, and I don't find this a particularly bad human trait, as long as people retain the ability to listen to reason when they hear it, and follow reason instead of thier guts if needed. Over the years, I've found that I keep asking myself one simple question about my beliefs. As long as I know the answer to it, I feel that my beliefs are reasonably ones for me to hold; I'm not just being dogmatic to believe in evolution, or libertarianism, or whatever.
That question is: What evidence would convince me that I'm wrong?
As long as you are open to evidence that your beliefs are wrong, then you know you've still got a sliver of reason guiding your guts.
So, if you believe in God, what evidence would it take for you to believe that you are wrong?
If you don't believe in God, what evidence would you need to see to doubt that you were right?
If you believe in global warming, what evidence would make you think that the theory didn't have merit?
If you don't believe in global warming, what would it take to convince you that it's real?
Here are a few of my core beliefs. Here's what evidence I could encounter that would make me pretty sure I'd been wrong:
1. Atheism. This is simple: If I were to witness the rapture, I'd just sigh and say, "Well, I called that one wrong."
2. Evolution. This is also pretty easy: If we were to discover, clearly, repeatedly and predictably, human fossils through all geologic strata, then I think there's be a good case that humans were seperate creations from the rest of the world's biology.
3. Global Warming. This is a tough one, alas. I don't think you could gather enough data over a human lifespan to genuinely document a cause and effect relationship between the current warming trends and human emissions. You would need centuries of hard data; right now, the numbers before the last few decades are somewhat muddy. We're documenting changes of tenths of a degree. Today, we have thousands, if not millions, off hard data points from all over the globe, measured with digital instruments that are accurate and calibrated against all the other instruments. Unfortunately, we are comparing our increasingly precise numbers against data that was gathered for much of the last century by somebody looking out a window at a red-line on a thermometer and writing down the number it showed.
Still, I can think of one thing that could persuade me: As we get better data from Mars, if we were to document a multi-decade cooling trend there, or even temperature stability, while at the same time documenting a warming trend here on earth, then you could make the case that the warming isn't due to natural flucuations in the sun. Right now, though, Mars is showing a warming trend as earth is showing a warming trend. Of course, again, the data for Mars for more than a few decades isn't great data. Still, if I must form an opinion on this in my life time, then that seems like a good starting point. If Mars cools or remains stable between now and 2020, and earth warms over the same time span, then I think I'd swing over to believing in global warming.
