  1. Check out the price of property insurance along the coastline of of Florida. That's the early warning sign. Right now, it's not an issue because those properties are mainly owned by rich people. But at some point in the future, those property owners will be forced to self insure. Then you might see some good deals.
  2. The point of this topic, however, is that neither of those things actually happened. One guy had a problem with some office politics, and wrote on his personal blog his dissatisfaction. The climate change deniers took that post and created a completely inaccurate story that was not based on the guy's original problem. He even later clarified that those stories were inaccurate.
  3. I guess you got your answer!
  4. Here is Dr. Muller's reasoning behind his change of mind from being skeptical to joining the scientific consensus: The Conversion of a Climate-Change Skeptic by RICHARD A. MULLER "CALL me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause."
  5. For comparison, we can see here that Lamar Smith makes $174,000 per year.
  6. Here's an interesting article that talks about the money climate scientists make and how they get that money. If climate scientists are in it for the money, they’re doing it wrong "So, are there big bucks to be had in climate science? Since it doesn't have a lot of commercial appeal, most of the people working in the area, and the vast majority of those publishing the scientific literature, work in academic departments or at government agencies. Penn State, home of noted climatologists Richard Alley and Michael Mann, has a strong geosciences department and, conveniently, makes the department's salary information available. It's easy to check, and find that the average tenured professor earned about $120,000 last year, and a new hire a bit less than $70,000. " "If they really wanted to make money at Penn State, they'd be coaching football or basketball. If they wanted to make money doing the sort of data analysis or modeling of complex systems that climatologists perform all the time, of course, they should go to Wall Street. "
  7. With all due respect, I have explained my understanding of the physics. You have disagreed, which is fine. But you failed to explain why my interpretation is in error and why your's is correct. More than one poster has written detailed explanations to you and the most response we can get from you is the equivalent of a "no it isn't". You rely on others to interpret what you are saying, and then disagree with their interpretation without providing one of your own. Your arguments are unsupported by references, links or documentation. You are not participating in this discussion in good faith.
  8. Please explain those real-world physics, please.
  9. Let's try this. How about you write up a description on how you think this experiment will work, and what the physics are behind it? Try to be as detailed as possible and assume we don't know anything. This will eliminate the problem of us trying to interpret what you mean from your posts. I think this is leading to confusion both your and our parts. Thanks.
  10. The bucket is not constant pressure. When you restrict the size of the hole in the bottom, the incoming water raises the level of the water in the bucket, therefore increasing pressure. I refer you back to this picture I posted earlier: With a different level of water in the bucket, you have a different pressure acting on the hole in the bottom. Different pressure = different flow characteristics. If there was no incoming water to the bucket, the water pressure at the hole would drop as the water drains out. Eventually, you would not have enough pressure to overcome the resistance from the restriction in the hole, and the flow would stop. If the hole is small enough, the flow would stop while there is still water in the bucket. Putting your finger over the hole, does increase the velocity, but only for a short while. As the level of the water decreases, the pressure differential between the water in the bucket and the water leaving the bucket decreases, and then the flow rate decreases. Then the water being pouring into the bucket increases the depth of the water, which increases the water pressure at the hole, which increases the flow rate. This happens until the flow rate into the bucket reaches equilibrium with the depth of the water in the bucket and flow rate out of the bucket.
  11. First, let me apologize if my response was insulting to you. That was not the intent. I was not trying to point out that water will flow out of a hole in a bucket, but WHY that is the case. More specifically, I was trying to illustrate the physics behind it. Clearly I did not communicate that effectively. However, after reading some of your responses, I think I have figured out where the disconnect is. The difference between your hose example and the bucket example is that the hose is a constant pressure system, and the bucket is a variable pressure system. Due to Bernoulli's Law, in a closed system, pressure is equal against all surfaces. That means that when you have your thumb completely covering the end of the hose, the pressure is the same against your thumb, against the walls of the hose, and against all the plumbing in your house. When you remove your thumb from the end of the hose, the pressure inside the hose is still the same. As the water leaves the hose, it is no longer constrained by the walls of the hose, and the pressure drops to zero (Bernoulli's Law again). The pressure differential between the water in the hose and the water leaving the hose causes the water to flow out of the hose (moving from a high pressure area to a low pressure area). When you partially block the end of the hose, you are creating a restriction in the system. The pressure inside the hose is still 45 psi (or whatever the city water pressure is in your house) and the water outside of the hose is still 0 psi. Since the pressure differential is still the same, the water still flows at the same rate (probably around 2.5 gallons per minute (gpm) or so). Since the pressure differential is still the same, and the flow rate is still the same, then the only thing that can change to account for the restriction on the hose (your thumb) is the velocity of the water. It speeds up to get around your thumb. Since the water is now going at a faster velocity, it shoots further out into the lawn. That is what you are seeing when you partially cover the end of the hose with your thumb. The more you cover up the hose, the faster the velocity of the water, the farther it goes. The less you cover the end of the hose, the slower the velocity, the closer the stream of water comes to your shoes. The pressure inside the hose never changed. If that was not the case, then, as pointed out earlier, if pressure increased as you added more restriction, there would be ever increasing pressure inside the hose and the hose would burst when you completely stopped the flow. Also, this is why the pressure in the faucet does not add to the pressure of the water in the bucket. Once the water leaves the confines of the faucet, the pressure drops to zero. This completely separates the pressure inside the faucet from the pressure at the bottom of the bucket. They are not additive because the water enters the bucket at zero pressure. Sorry for the wall of text. I hope this clarifies the physics behind what we are discussing.
  12. That's not true in his analogy. Fill a bucket with water. Turn off the hose so that there is a static amount of water in the bucket. Now, poke a hole in the bottom of the bucket. Does the water flow out of the hole? Yes, it does. It does so because of the pressure of the water in the bucket. The pressure at the surface of the water is less that the pressure at the bottom of the bucket. The amount of pressure is determined by the height of the water.
  13. That statement is half-true. The summer season is getting more hot, but the cold season is not getting colder. One indication of this is the number of new low temperature records compared to the number of high temperature records. In a steady, average climate, you would expect them to be about equal. In a cooling climate, you would expect more cold records than warm records. In a warming climate you would expect more warm records than cold records. From here: "What’s not obvious in the maps and figures above is how seldom U.S. towns and cities set or tied daily record lows in 2016, thanks in large part to the mild nights noted above. The preliminary total of daily record lows for the year was 5188--barely half of the total recorded in any other year since 30-year climatologies became established in the 1920s, according to independent meteorologist Guy Walton, who has compiled and tracked NOAA records data for more than a decade. Meanwhile, there were 29,729 daily record highs, a large but not unusual number for recent years. Juxtaposed, the ratio of daily highs to daily lows was around 5.7 to 1, the largest for any year in the post-1920s database, according to Walton. Overall for the 2010s (defined as 2010 - 2016), we’ve seen more than double the number of daily record highs versus lows, with the ratio of 2.1 to 1 just above the 1.9-to-1 ratio observed in the 2000s."
