I'll concede (because I am such an honest and gracious person) that ice located on land that melts and runs into the ocean will raise ocean levels. So? So what's the big deal about? You think this is the only time in all of history the ocean level has changed? Are you really this vain? I once again call your attention to maps of the world from 100 million years ago, showing the oceans covering much of what we today call continents.
Speaking of ice, oceans and water, has it ever occurred to anyone (other than me) that the totality of all the water from eternity past to eternity future has never changed? In other words, the total volume of water, whether the water is in the oceans, rivers, lakes, underground, frozen, or in the air, has remained absolutely constant and the same, world without end. The only thing that has changed is the location and nature of the water. I find that very interesting. This is a fact of nature evolution cannot come close to explaining. The total and unchangeable sum of all water could not have begun with a single drop, because if it did, the process that caused that first drop to form would still be in effect and continuing, resulting in an ever expanding volume of water being created, and eventually displacing and covering all the earth. Yet, the fact is the total volume of water on earth is incapable of ever changing (unless for the small amounts astronauts leave in outer space).

As you consider global warming, do yourself a favor and watch the Weather Channel (there is a point to this, just keep reading). Try to catch a ten-day forecast. Write down exactly what the prediction is. Ten days from now, see what the weather is. As I'm sure you are already aware, weather and climate prediction are far from an exact science.
Our problem is that we deal with a mixture of repeating conditions and non-repeating conditions. Repeating conditions are things like the eleven-year solar cycle, the Earth's magnetic cycle (the magnetic poles shift back and forth, north to south and vice versa, over time), etc. Non-repeating conditions include meteorite impacts, the aging of the sun (aging does not necessarily mean cooling, mind you; nuclear fusion is a terribly complex process), and mankind's impact. My opinion is this: the Earth, like most things in nature, is remarkably good at maintaining its present state. The Earth's climate is in a state of equilibrium - this is a "resting" state, or the point of where energy is distributed in the most entropically favorable situation (sorry for the thermodynamics terms). In other words, think of a bowl with a marble in it. The marble will always gravitate towards the bottom of the bowl because that is the most energetically favorable state for it to be in. How do we know this? We know that when the Earth is thrown temporarily out of this resting state, it returns to it. Examples: Ice Age, major meteorite impacts, even major volcanic events. What we need to be careful of is not to shake the Earth so hard that it falls into a different resting state - in the bowl example, knocking the marble out of the bowl. We don't know if there is another even more stable climate state. Odds are, there isn't. But considering that all of our lives are on the line, I don't think that's a chance we should take. This has gotten far longer than I intended, so I'll wrap it up. Humans have most definitely impacted the environment, but we are certainly not the most serious impact in Earth's history (the meteorite strike 65 million years ago released an amount of energy roughly equal to one million times the largest hydrogen bomb ever detonated (an estimate, of course)). We need to do something, but I highly doubt that we are on a doomsday course that will end humanity. |

I didn't get to hear all of the Algore show yesterday. Did he explain how variations in solar radiation doesn't affect our temperature? Did he explain why we're not supposed to pay attention to Mars' melting ice caps? Did he explain why the Earth's history of climate cycles prior to human existence needed to be factored out of his sci-fi movie? Being a good, honest Liberal his dupes think he is, I'm sure he meant to. Did they give him enough time? With only 4 hours available, I can see where those details mind just slip his mind |

Meteor impacts can cause extinction. A rock 10 miles in diameter (a tiny fraction of the Earth's volume) can cause such an event. The balance of life on Earth is a very delicate one. While global warming does not have the immediate impact of a large meteor, there's always the danger of a tipping point as a worst-case scenario. It's probably not too likely, but why push the envelope?

Alberto, Helene, Beryl, Isaac, Chris, Debby, Ernesto, Florence, Gordon and one that got away before it got named.
But then there are also Typhoons: http://en.wikipedia.org/wiki/2006_Pa...Typhoon_Season and of course pacific hurricanes The cumulative ACE for the Eastern Pacific this season fell within the official "Near Normal" grading, even though the number of tropical storms, hurricanes, and major hurricanes was above the long term average. http://en.wikipedia.org/wiki/2006_Pa...rricane_season For background information on averages http://www.cpc.ncep.noaa.gov/product...formation.html |
