Where are the numbers?31-01-2019 17:36 | |

They say average global temperature increased 0.6C in the 20th century. Where's the proof? Where's the 100 annual average global temperatures from 1900 to 2000? Without numbers, without proof, why should anyone believe their claim?

I don't think anyone really knows where the IPCC pulls their numbers. They would be meaningless anyway, no standardized equipment, no standard for taking readings, and no where near enough thermometers to cover even a fraction of the world. Are they only looking a daytime highs. Do they include all the recorded temperatures available, or just pick the ones that fit best on the Hockey-stick graph? We know there were some manipulations, to get those smooth curves. Don't recall any margin of error ever noted along with their graphs. Really doesn't matter, Since there were no CO2 measurements to go with the pseudo-temperature readings, until 1958, and only one location (Hawaii). As this thing progresses, it really looks like they made their conclusion the CO2 was going to cause Global Warming, before they had any data to support it. Their 'research' seems more like a search through published papers, for anything they could use parts of, to patch together a convincing argument. There is so much argument and debate, it should be obvious to most, that it's not the truth, or factual. There is no real data, just computer simulations, of what some think, could be possible, but nothing real to support it. The controversy is good advertising, keeps it in the news, and on everyone's mind. |

The "100 annual average global temperatures" would be some sort of summary, not actual original evidence. Actually the literal "average global temperature" wouldn't be useful anyway since you'd be including the hot interior of the Earth. Mean global near-surface air temperature maybe?

The little 5mm LEDs produce heat, but they are encased in epoxy, which is a good enough heatsink. They make much more powerful LEDs these days, that put off a lot of heat, which needs to be managed. LEDs are current driven, just need a small voltage to make them conduct, and they take as much current as you give them. You need to limit that current, or they destroy themselves. Properly used, they are very efficient, compared to other options. |

HarveyH55 wrote: The LED itself inside of the 5 mm case is tiny. The cathode wire is almost large enough to block the light output and that has to be handled. That is why they are so badly current limited. That cathode attachment will burn out long before the LED chip. Also - the LED output is unidirectional so it is only a dot that has to be enlarged using lenses. The tops of those LEDs are the lense. When they originally came out we did all sorts of experiments to discover how much of the hyoe was true and most of it was. When you pass the LED light through a lense, the plastic isn't the proper color and so you lose quite a bit of power into the plastic. The last project I worked on have several units and one of them was battery powered and used the LED color to signal the state of the battery. So I would measure the battery voltage and time the flashes of a double Red/Green with mixed wavelength so that the color would go Green for good, then Yellow for needs a charge, to Red - none of the results are reliable. I would use the time off on the flashes to control the amount of power that they used because power usage was important. Edited on 03-02-2019 23:25 |

LEDs also work as regular diodes, they can be used to detect light, and the can also be used as solar cells. The lens is for focus, a small angle, gives a brighter, smaller spot. A wide angle, spreads it out, but you lose brightness, but cover more area. The color temperature, is a comparison of the light given off some metal heated until it incandescents. Don't remember the metal or the details, but it's just one of those standards things. |
