Global warming: Lower atmosphere, upper atmosphere

As the deniers continue to spread their poison, many people are left unprepared when dealing with their lies. There are many well-known facts about global warming; but there is one that is not widely known, and it offers conclusive refutation to those who claim that it's the sun or cyclical fluctuations.

Want to know a way to talk back to people who claim such things? All you need to know is just one fact:

The lower levels of the atmosphere have been shown to warm, and the upper levels of the atmosphere have been shown to cool, over recent decades.

If it was the sun, or anything cyclical, the whole of the atmosphere would have warmed. Instead, lower levels have warmed and upper levels have cooled.

There is only one possible mechanism for this:

Carbon dioxide and methane accumulating in the atmosphere to reflect sun's rays bouncing off the Earth's surface back to the Earth, causing the lower atmosphere to become hotter -

While allowing fewer of them to escape into the upper atmosphere, causing it to cool.

So anytime anyone claims that it's the sun, or that it's cyclical fluctuations, have this simple fact as response.

Just as much as the right response to the claim that it's a UN hoax is the simple fact that science knew about it long before UN had anything to do with it, and UN took it on before the American Right because the UN is more rational and responsible than the American Right.
