Here is the most concise definiton of enthalpy I managed to find: # S: (n) heat content, total heat, enthalpy, H ((thermodynamics) a thermodynamic quantity equal to the internal energy of a system plus the product of its volume and pressure) "enthalpy is the amount of energy in a system capable of doing mechanical work"
Don't know if that helps or not. |

Well that's cool. But this past week NPR's All Things Considered has been doing a series on climate change and the term "global warming" is still being used by the interviewers and some of the interviewees as well. Ah well. |

Back around 1965 or so the big concern about the possibility of the climate changing centered around the idea we were possibly due for another ice age. About three years ago there was an article in the local paper about a climatology professor who teaches here at ODU. This guy studies the sediments in ice cores at the boundaries at the beginning of past ice ages. He was saying that the sediments now being deposited at new ice formations in the winters at the poles resemble what he sees at the the beginnings of previous ice ages.
A few years ago, "global warming" was all I heard about. "Climate change" seems more recent. I think it may have something to do with some of predictions made centered around the "global warming" models have fallen through. I watched Gore's film An Inconvenient Truth about a year ago at my mother's urging. I would have been far more impressed by it if it didn't seem as though it were more about Al Gore than the environment. One of the things Gore mentioned was that people who expressed concern about global warming were in danger of losing their jobs in government and large corporations. But, the only incident like this that had come to my attention was when the head of NOAA said that we were not having more frequent hurricanes and the hurricanes we were having weren't any worse than they had been historically. I'm not sure what became of him, but there was talk of the Bush administration asking for his resignation. This was after Katrina. I know that year was bad one for hurricanes and climatologists were predicting the next hurricane season would be far worse. In fact, it was far milder than anyone had any reason to expect. A couple of weeks ago, there was a story on NPR concerning a threefold increase in detected short-lived tropical storms in remote areas of the ocean. This puzzled climatologists, because they all acknowledged that there was no sound reason based on everything they knew that these short-lived storms should increase so much without a corresponding increase in the more dangerous longer lived ones. The consensus seemed to be that in recent years we have launched several more satellites designed to monitor the climate and we had far more coverage of far greater areas of the globe than we ever had before, so we were detecting these storms before they died out much more frequently than we ever were before.
All of which leaves me up in the air about either "global warming" or "climate change". Though I still think it is a good idea to monitor the situation and make some effort reduce the carbon dioxide in the atmosphere. |

Well, I'm not too sure about global warming at all. Last week, Sharon was telling me it snowed in Pennsylvania, the earliest snowfall there in recorded history. On the other hand, right now it is 70 degrees Fahrenheit at 0807 in VA, near the end of October and that doesn't seem quite right to me either. So, I'm not really too sure what is going on.
This much is fairly certain though: at various times throughout geological history, it has been considerably colder and considerably hotter on Earth than it is right now, but as the song goes, "Life goes on bra, oh how the life goes on..."
A couple things I don't understand about the global warming models though. One is why methane is 23 times more efficient as a greenhouse gas than carbon dioxide. Methane is lighter than air, which means it is less dense and therefore contains less mass to hold heat. So I am not too clear on the physics involved in what makes methane a worse greenhouse gas than carbon dioxide. But, if it is true, there does seem an obvious solution, which is to use the methane as a fuel, thereby converting it into more carbon dioxide, which is less effective as a greenhouse gas, right?
I'm not too sure how effective giving up meat would be either. I like this comment a good deal though, from one of the readers of the article:
" Travis Pedley wrote:
So then cows are a large part of the methane problem. As someone who was raised in an alternative household (veganism is for wimps lol) but who retained his meat eating credentials throughout, I can say with some authority that a vegetarian diet causes flatulence at levels, that seem at least, comparable to those found in cows. What we should be doing is to focus on good animal husbandry, cook from fresh more and move away from energy heavy processed foods. This should stop the fatties from getting bigger too. Stop the Vegetabalists now!" |

A: It seems to be. I don't often get sick.
Q: When was the last time you were sick? |

Happy Birthday, mama! So you're 19 now? Is it any different than being 18? It's been so long, I can't remember.... |
