First, take into account we are talking about global temp. averages. (I hear so many critics that look at local data only.)
****Global averages of what, your graph says stratophere and our weather occurs in the troposphere.
****Average troposphere temperatures are what count.
****Decrease in ave temps in stratosphere indicate that there is less ozone to absorb UV rays, therefore that layer should be cooler. Thats easy less ozone on average, less UV absorption on average, less warmth for the stratosphere, temps drop a degree.
****Meanwhile in the troposphere we absorb all the UV light in this layer, the oceans, land etc. Granted there is some surface albedo, but we have more radiation (heat energy) making it down to the troposphere and therefore global warming, like the enviro freaks keep talking about.
****I am not sure why you included this since tropospheric temperature changes are not occurring in the same direction as the stratophere temp changes you mentioned.
Satellite data has been shown to be much more accurate due to both sample size and Urban sprawl.
*******Your looking at satellite data measuring the wrong layer of the atmosphere, great investigative work, I just think maybe you forgot that the atmosphere is composed of different layers.
We know that glaciers are growing in some areas and shrinking in others.
Cool, I did not know glaciers are growing. What ice shelves are growing? By how much and where are they? Fascinating investigative work you have done. Tell me more!
As for the stratosphere, troposphere, etc. Wouldn't you think there would be a massive increase in all atmospheric temperatures if green house gasses were causing global warming.
No, I wouldn't think there would be an across the board increase because you can see that temperatures do not increase linear throughout the whole atmosphere.
Remember your atmospheric science?
I didn't at first, but heres the link that descripes the abrupt rise in temps one expereinces as you rise out of the top of the troposphere (negative 70C) to the stratosphere (0 to -3C) remeber the ozone layer thhrows a wrench in it.
Maybe I misread the graph, here's Nasa's description.

Your graph only shows satellite data of the stratosphere. I guess those meteorologist named the different parts of the atmosphere because there can be some surprises to common sense or intuition in how the whole thing works.
Great points Rodney. I am glad you are standing up for corporations! I love to hear you opinions! Keep writing!
I hope you understand the questions I have asked! Sometimes I may not write so clearly!
