Why does greenhouse effect make Earth's surface so cool compared to what it would otherwise be?02-01-2016 01:45 | |

A metal bar in space heats to 260 C when sunlight shines on it. On a cloudless sunny summer day, a dark pavement outside only heats to about 28 C, hardly distinguishable from the air temperature. Is this proof that greenhouse gases cool the world? I quote. A piece of bare metal in space, under constant sunlight can get as hot as two-hundred-sixty (260) degrees Celsius. This is dangerous to astronauts who have to work outside the station. http://www.universetoday.com/77070/how-cold-is-space/ This is greenhouse effect. https://www.youtube.com/watch?v=ZzCA60WnoMk Edited on 02-01-2016 01:58 |

On the average, solar intensity is 30% higher at the top of the atmosphere compared to the surface, although on a cloudless sunny summer day that % could very well be less than 10%. But this does not seem to be enough to account for the much cooler temperature at the surface, where temperature is about 28 C instead of 260 C if there were no atmosphere. https://en.wikipedia.org/wiki/Sunlight Edited on 02-01-2016 02:31 |

Tai Hai Chen, I'm starting to suspect that you are only pretending to be this scientifically illiterate and stupid, and posting all your ridiculous pseudoscience nonsense threads is to try to make climate science deniers look even stupider, more ridiculous and more scientifically illiterate than they already are. Keep it up. This forum already became a joke because of the efforts of a couple of climate science denier trolls. You might as well make it a complete farce. Edited on 02-01-2016 03:14 |

Tai Hai Chen wrote: Your source isn't wrong, but you are. The 260 C figure they used was referring to a small metal bar in constant sunlight in a vacuum, not the earth's surface. Try again. By the way, what makes you think Universe Today is a 'reliable source'? Because it sounds sciencey and looks glitzy? They are just a couple of laymen running an online mag, not a science institution or an educational source or a science Journal. Looking at some of their other videos and articles, they seem to do a reasonable job of putting some simple science concepts into fun simplistic terms for lay people. They even answer your question on the temperature of the earth without an atmosphere in the link below. It's not exactly scientifically correct because they don't take other variables into account, like different length of time the earth and moon rotate on their axis etc and they use simplistic analogies, but they are not too far off: http://www.universetoday.com/48328/earth-surface-temperature/ But apparently even that website is too confusing for you if you came away thinking that the earth is the same as a small metal bar and the earth's surface could be 260 C without an atmosphere. Did it ever cross your mind to read a science textbook to get the basics right? Here's one on an Introduction to Atmospheric Chemistry you can read that has been made freely available online for undergrad students: http://acmg.seas.harvard.edu/people/faculty/djj/book/ But then again, maybe you should try NASA's climate kids website to start with.

I quote.Consider, for example, the International Space Station (ISS). Without thermal controls, the temperature of the orbiting Space Station's Sun-facing side would soar to 250 degrees F (121 C), while thermometers on the dark side would plunge to minus 250 degrees F (-157 C). http://science.nasa.gov/science-news/science-at-nasa/2001/ast21mar_1/ This means Earth's atmosphere regulates Earth's temperature. Without Earth's atmosphere, Earth would be extremely hot during the day and extremely cold during the night. What I do not agree with NASA is that convection does very little in regulating day and night temperature differences. It is mainly greenhouse gases that do that because they retain the heat they absorb during the day and slowly release that heat at night. Edited on 04-01-2016 00:17 |

Tai Hai Chen incorrectly asserts the earth would be 260 C without an atmosphere. IbdaMann tells Tai Hai Chen he is correct. IbdaMann then says it wouldn't be 260 C, it would be 240 degrees Fahrenheit - which is 115 C Then Tai Hai posts a quote from NASA about the space station's sun facing side getting as hot as 121 C You guys are hilarious.

You also didn't get the hint that the earth rotates on it's axis every 24 hrs (the moon every 27.3 days)- a small piece of metal in space does not. There is also the issue of the size and composition of the earth compared to a small piece of metal.

NASA is a governmental organization. NASA is a mouthpiece of the American president.

Tai Hai Chen is right about one thing at least - the effect of greenhouse gases on temperature. Look at this spectrum of the IR radiation emitted by the Earth as measured from above the atmosphere by satellite instruments. Note the deviations from a pure blackbody spectrum in the form of large dips corresponding to the absorption bands of various greenhouse gases. |

Energy that is not emitted from one part of the spectrum must be emitted elsewhere in order to maintain energy balance. The blackbody temperature must therefore increase in order to compensate for the energy absorbed in the "notches". This is the greenhouse effect in action. |

The location and depth of the "notches" does indeed depend on the composition of the atmosphere. Indeed, we can determine the composition of the atmospheres of other planets (and even stars) by examining the "notches". It's called spectroscopy. In turn, the amount of blackbody radiation removed from the emission spectrum depends on the size of the "notches". This radiation that doesn't make it out into space causes the temperature of the planet and its lower atmosphere to rise until equilibrium is re-established. Hence the temperature of a planet is indeed partly dependent on the composition of the atmosphere, in particular, the concentration of greenhouse gases (those that absorb IR radiation). We've known this since the late 1800s. |

Surface Detail wrote: Right start, wrong conclusion. The notches do depend on what is in the atmosphere, but the radiation still makes it out into space via the general temperature of materials surrounding the one that absorbed energy. The temperature of the atmosphere is not dependent on any particular substance in the atmosphere. The notches make no difference. You are trying to argue the energy trap again. As I've stated before, that effectively produces a perpetual motion machine of the 1st order.

Do we all agree that, without the atmosphere, if you stand on the surface of Earth and hold something out under the sunlight, that thing will, within a short time, say within minutes, heat to well over 100 C? |

Why doesn't this emitted energy show up in the emission spectrum? As for the perpetual motion machine, I've no idea what you're talking about. I suspect you've misunderstood something. |

The atmosphere is a uniform temperature for any practical purpose around that molecule, including the molecule itself. The emission produced by the atmosphere is uniform and dependent only on the temperature of the atmosphere as a whole. If the CO2 is in the troposphere, heat is lost primarily by conduction and convection rather than emission. Emission takes place both day and night. Like water and the other gases of the atmosphere, carbon dioxide only moderates temperature extremes from day to night. It doesn't raise the mean temperature at all. If you build any kind of energy trap, then any amount of additional energy must necessarily add to that trap. Over time the trap will destroy itself. By claiming that CO2 or any other gas is causing warming is just such a trap. Such a trap is not possible. It would be creating energy out of nothing, since it would be storing energy indefinitely. This is effectively a perpetual motion machine, powering emissions from the planet yet storing energy indefinitely. Any amount of energy added to the trap will result in a feed forward loop that causes hotter and hotter temperatures over time until the trap is destroyed catastrophically. The Earth would be utterly destroyed. Since CO2 has been in the atmosphere at higher concentrations than now in the past, this should already have happened if it were possible.
