There seem to be lots of things missing or that just plain don't work.
That's not a question. Its a statement. It's an honest mistake to be sure, but maybe its a sign that you should start spending more time thinking about how you might improve yourself and a little less time nitpicking every little detail of any given website.

What happens when mini ice age meets global warming? Mega Ice Age!?

http://i.space.com/images/091217-thermosphere-sat-01.jpg Lately the sun has been going through a bit of a quit period. These episodes historically have resulted in the cooling of the earth and what we aptly call a mini ice age. So what happens when mini ice age meets global warming? Nothing good.

Scientists argue that the relationship between the sun's inactivity and global cooling may result from the swelling and shrinking of the earth's atmosphere.This same phenomenon also effects the orbits of satellites and space junk. As the atmosphere becomes cooler it changes the density of the atmospheric layer. This change in density may cause satellites and junk found in this area to sink to lower altitudes.

Scientists now are trying to better understand the earth's thermosphere or the place where the sun first interacts with our atmosphere. Over the last 11-years solar cycle this area has been responding dramatically, resulting in intense cooling in some parts.

These results present potentially life concerning issue resulting in how the effects of global warming and CO2 emissions will have when paired with the sun's inactivity. While intuitively it may seem that CO2 should counteract the current oncoming ice age and kinda balance out temperatures. It would be wrong to think that way. CO2 emissions will actually cool these areas further because carbon dioxide causes warming in the lowest part of the atmosphere and cooling in the upper layers of the atmosphere. However so little is known about this thermosphere that until now we are only beginning to understand the consequences of the interaction of other systems not just the lower atmospheric layers.

"The exact temperature of the thermosphere can vary substantially, but the average temperature above 180 miles (300 km) is about 800 degrees Fahrenheit (427 degrees Celsius) at solar minimum and 1,700 degrees Fahrenheit (927 degrees Celsius) at solar maximum. (Though these temperatures sound hot, you would not actually feel warm in the thermosphere, because the molecules in that layer are too far apart.) "

That's cool (pardon the pun), but I wonder if while you would "not actually feel warm" would you also implode?

I was looking up your question and I did not find anything on the effects of heat in that type of environment but I did find a interesting article about whats happens to the body in pressures that low.

based off of the article I would think rather then implode the body would explode.

one of the first effects would be the expansion of gases within the lungs and digestive tract due to the reduction of external pressure.In the absence of atmospheric pressure water will spontaneously convert into vapor, which would cause the moisture in a victim’s mouth and eyes to quickly boil away. The same effect would cause water in the muscles and soft tissues of the body to evaporate, prompting some parts of the body to swell to twice their usual size after a few moments. This bloating may result in some superficial bruising due to broken capillaries, but it would not be sufficient to break the skin. Within seconds the reduced pressure would cause the nitrogen which is dissolved in the blood to form gaseous bubbles, a painful condition known to divers as “the bends.” Direct exposure to the sun’s ultraviolet radiation would also cause a severe sunburn to any unprotected skin.For about ten full seconds– a long time to be loitering in space without protection– an average human would be rather uncomfortable, but they would still have their wits about them. Depending on the nature of the decompression, this may give a victim sufficient time to take measures to save their own life. But this period of “useful consciousness” would wane as the effects of brain asphyxiation begin to set in. In the absence of air pressure the gas exchange of the lungs works in reverse, dumping oxygen out of the blood and accelerating the oxygen-starved state known as hypoxia.At this point the victim would be floating in a blue, bloated, unresponsive stupor, but their brain would remain undamaged and their heart would continue to beat. If pressurized oxygen is administered within about one and a half minutes, a person in such a state is likely make a complete recovery with only minor injuries, though the hypoxia-induced blindness may not pass for some time. Without intervention in those first ninety seconds, the blood pressure would fall sufficiently that the blood itself would begin to boil, and the heart would stop beating. There are no recorded instances of successful resuscitation beyond that threshold
