Of course the earth is warmer because it is warmed from the inside as well as from the sun. That's part of it. But it's also because the Earth doesn't radiate all that well, either. It holds a fair amount of the heat that strikes it. Air is a great insulator ![]() Also, greenhouse efeect, skewing the ratio of heat gained vs heat lost... The UK just had a half-week of mid summer temps at Halloween. Never mind 'weather Recorded temperatures have always set new records. Just considering one location, there are 365 days in a year and so 730 high and low records to test. We have been recording temperatures for roughly 200 years. What are the chances we *won't* set a new record for one of those dates in a given year? -- Rick |

And given the Maunder Minimum soem big excursions can be expected, especially as the sun isn't following its usual 11-year pattern. On the other hand I remember people asking me in 1983 about glonal warming, and me insisting that it did not just mean warmer, but wetter, stormier, as well. There's no doubt that compared to thiry years ago this has happened across most of thwe world. For a real balance of 'records', we need to know how often the record for quietest, or closest approach to average, conditions occured, and I have never heard the like. Generally, if news is not exciting, it is not considered as news. Also, even when we had unusual cold recently, it is arguable that climate conditions don't cause a strong enough gradient to keep a strong division of temperature with lattitude, and similar things can be said about the wandering of the jet stream. Too many things look new, an the rate of broken records is increasing when it ought to be decreasing if things were generally stable. |

Let the scientists analyze the data and come up with facts. -- Rick |

Too many things look new, an the rate of broken records is increasing when it ought to be decreasing if things were generally stable. The problem is the Earth's climate is a very complex system. You can't take a small area and project what's happening world-wide; things are too interconnected. This would be like taking one street in a big city and count cars going by. If the number of cars goes down, you can't say "traffic in the city is lighter" because there might have been an occurrence such as an accident on a feeder road which is blocking up traffic. At the same time, if the number of cars increases, you can't say "traffic is heavier" - there might have been an accident in another location and people are getting around it by using this street. It's all tied together. A perfect example with the weather is last winter. North America had one of the coldest winters in recent years (due to the polar vortex moving our way). But Europe and Asia had one of the warmest winters in recent years; world-wide the average temperature increased. The last figure I heard was that 95% of climatologists (people who should know better than anyone else) agree that global warming is occurring, as indicated by world-wide average temperatures. There is still debate, even amongst them, how much man is responsible for this warming. But still the vast majority believe that man is responsible for at least some of the warming. So, as rickman pointed out, (paraphrasing) with only 200 or so years of tracking temperatures (even less than that in much of the Americas), there is almost a certainty some locations will report record highs, and some locations will report record lows. -- ================== Remove the "x" from my email address Jerry, AI0K ================== |

I'll let the matter rest. I actually have no axe to grind either way. I just found it odd that people I knew did not realise that 'warming' could likely mean 'more dynamic'. Whatever the outcome or cause, we have to adapt to changes or we're stuffed. |
