I can't stand deniers say CO2 is not important because it's only 0.04%25-12-2015 02:51 | |

True, it's only 0.04%, but it's enough to sustain all plant life on the planet. As a comparison, ozone in the ozone layer is less than 10 parts per million and it is able to absorb just about all UV radiation from the Sun, enabling Earth to sustain life. 0.04% of the Earth's air is relatively small, but remember Earth has a lot of atmosphere, and 0.04% of the Earth's air is still 720 billion tons. That makes a pretty thick layer, much thicker than the ozone layer. https://en.wikipedia.org/wiki/Ozone_layer https://www.youtube.com/watch?v=MR4GrHPDcWE Edited on 25-12-2015 03:03 |

The issue is global warming, and best way to determine that is by direct global measurement, not by indirect symptoms. It's similar to someone in a house saying "I feel hot, don't you feel hot?". Then you look at the thermometer and it says 70F. The two different satellite measurement systems have only been around since about 1979, but that should be sufficient to corroborate the rapid spike in average global temperatures allegedly caused by rising atmospheric CO2 levels -- if it were occurring. So far they are not indicating that. Also they make true global measurements, which is appropriate since the issue is global average temperatures. |

The UAH and RSS satellite data correspond fairly closely. However extreme accuracy is not needed to illustrate my point. The conventional view is global average temperatures are skyrocketing -- rapidly and unambiguously increasing at an extreme rate. That is why it's called a "hockey stick". Another example, and note the red graph is allegedly instrumented data, not a model prediction: http://www.ncdc.noaa.gov/paleo/pubs/mann2008/fig3.jpg The satellite measurements -- the only true direct global temperature measurements -- do not show that. |

jdm wrote: How do you mean, profound? (referring to your first 12/27 post) Near as I can tell, the latest temperature anomaly in the hockeystick graph is a little over 0.4C, the UAH graph anomaly is 0.33C. Also, the baseline periods for figuring the anomaly are different, 1981 to 2010 in one instance, and, I think, the 20th century in the other case. The overall shapes of the graphs would be expected to be different, given the different time periods involved. The UAH graph can't show any bending that occurred before 1979.

jdm wrote: I'm really not sure what you're talking about. Allow me to roll my eyes. Please, please, please, please and pretty please tell me how you were so easily convinced that you or anyone else knows that the average global atmospheric temperature is increasing...skyrocketing even, when the truth is that as far as anyone knows our planet could be cooling right now, and probably is? I'd really like to know how you were convinced. Are you aware that warmizombies declare that "skyrocketing" Global Warming is occurring at an imperceptible rate of a couple of tenths of a degree every few decades? That would require global average atmospheric temperature accuracy of much better than a mere couple tenths of a degree. We don't have anything near that. So let me fire the question back at you: What are you talking about? To measure any sort of change (increase or decrease) in temperature you need at least two values...followed by a subtraction operation. Please show me all the raw data that went into computing the first global average atmospheric temperature, all the raw data that went into the second such temperature, the math used and the margin of error for each data point. I'm guessing you don't have, nor have you seen, any of that. I'm guessing you simply saw conveniently provided "already-computed" change values and that you never questioned them...but are somehow expecting others to be as gullible and to just accept the numbers they are handed. jdm wrote: Global satellite temperature measurements cover about 98% of the earth's surface, ...all synchronized to take measurements at the same instant? Are you aware that satellites suffer from the major problem that they can't get anyone up into orbit to ever calibrate them? Do you understand what that does for their margin of error and to our confidence in the measurements? jdm wrote: However extreme accuracy is not needed to illustrate my point. I bet this is going to be good. jdm wrote: The conventional view is global average temperatures are skyrocketing -- rapidly and unambiguously increasing at an extreme rate. The conventional science view is that what you are describing is simply not possible and that observations of the solar magnetic field indicate weakening solar output which means the earth is likely cooling right this very instant and that it will likely continue to cool over the next few decades. .

E.g, it has been described as already being a "state of planetary emergency", and a key factor in that viewpoint is the near-vertical slope of that graph: http://www.climateemergencyinstitute.com/catastrophe.html My point is that is not what the satellite data indicates. |

The correct words are "margin of error" and "confidence." We certainly trust uncalibrated sensors to lose accuracy and to increase their margin of error, thus reducing our confidence in their measurements. jdm wrote: As I said the UAH and RSS satellite data correspond fairly closely, Big deal.

JDM - the two graphs obviously have a very different scale, so there really is no way to properly compare them. The OPs message, that trace amounts can still have major effects, isn't resolved by attempting such comparisons. |
