You guys think global warming is a myth? Where the fuck do you get your data from? Alex Jones?

The sun is expanding. Whether or not that means less energy output, it doesn't take a whole lot of heat to melt the polar ice caps and completely fuck up our ozone layer, allowing ultraviolet radiation to completely burn out all life on the planet. While it would take eons for this to be visible. It still will cause massive weather pattern differences, which is why it FEELS colder. But infact, we're losing water, ice, and life.

Now, as a man of science, I'm not going to call you retarded for holding a different hypothesis. But this is worse then the whole "smoking causes cancer" thing. Yeah, maybe after twenty years of smoking, it may contribute to it's development... but it doesn't "CAUSE" cancer. You won't smoke and wake up the next day with cancer.

Tobacco is regulated because people with cancer cost insurance companies money, the same thing applies to global warming. We ignore it because then you lazy fucks would have to whip up some engines that can run on canola oil and cough syrup. Which is possible, you're just being procrastinators.

Well that too. But I'm speaking about fissionable materials as opposed to fissile materials. Also the energy range in which they operate is sort of hard to control. Fast neutron ranges tend to be tricky. Most neutrons born from fission are fast, and you need to maximize absorption while minimizing scattering materials to make a safe, efficient fast reactors.

Also, fast reactors take a large amount of energy to start up anyway. And like I said, once you get fast fission going, it'll work and it'll be efficient but you walk a thin line in that energy range.

Also, had a lot of caffeine recently so if I seem a little whacked out, it's because I am.

Sure, I may eat my words when India gets there Thorium reactors running, and then you'll eat yours when it goes prompt critical unexpectedly and exposes plant works to neutrons that are literally orders of magnitude higher than you can comprehend with nothing to moderate them or absorb them.

I'm not saying it should be abandoned, and it's not. It's just being rushed. You'd actually be better off doing something like the Canadians and running natural enrichment with heavy water moderates or abolishing laws on mandated burning times of fuel within the US.

Which is another matter. There are tons of reuse and recycle methods that are in use today (by the French and others) and some that are in development that literally double the available burn time of our fuel stock pile and by the end would have a negligible mutagenic effect and near negligible carcinogenic effect in the waste.

My point is that there are better, more established ways in branching nuclear power without the use of Thorium. Seriously man, don't tell me that I'm wrong when I've worked on a degree in the matter.

Not at all actually. The way things are in the US, the only thing preventing burning a fuel rod past 18 months IS the law. No if, ands, or buts about it. You could literally just keep the rods in the reactor for 36 months until they accumulate too much xenon to be efficient if Congress didn't mandate scheduled refueling.

Additionally, most of our Uranium is imported. It'd be much more efficient just to burn what we have rather than import it.

I have no beef with burning it a little longer but reprocessing it is still more expensive than getting new stuff. Also ageing it dose most of the work for you as the nasty stuff dies out fast. Stick it in the utah desert for a few decades and reuse it, it's the most elegant solution.

I don't know if it can be stopped or reversed (well, at least not in the next several generations, it will naturally reverse itself given time). However, we can certainly avoid making it worse. There is definitely a warming trend, and we may or may not be the primary cause of it, but even if we aren't we still stand to benefit from curbing our own emissions.

Because these boards seem vaguely less troll infested than the rest of 4-chan I will, in fact, feed them.

Yes, global temps have fluctuated before, the most recent Ice age of course being the most recent example of this. That said, IT WENT WAY THE FUCK SLOWER BACK THEN!!!!! Yes, some animals went extinct but others evolved. Lots of others. But things are moving so quickly that evolution cannot keep up this time. And that, my loves, is a serious problem.

Further more, I expect people on this board to be smart enough and educated enough to not think that the existence of cold weather means global warming (aka global climate change) isn't happening. Seriously, at least understand what you are arguing about or you will just sound like a moron.

of course there's Global Warming, you can't put this much Co2 into the atmosphere and not have it warm a little. But the climate is dynamic, it's changed before and it will change again. Historically a warmer climate is a good thing. In fact they say humans themselves evolved into what we are today because we were able to deal with a warming climate. And the inhabitable areas of this planet are limited by how cold they are, not how hot.
This isn't the Apocalypse people. It's going to get a little warmer, the weather is going to change a bit, but we will survive as a species and be better for it.
