Amidst Global Warming Hysteria, Nasa Expects Global Cooling

Is this legitimate? I can't tell anymore when I read articles about climate change, because both sides seem to mix in some lies or half-truths and misrepresent what the situation really is.

I've read parts of the IPCC 2014 report and they seem to be contrary to what the article is about. On the other hand, some of the things I read in the report did make me question the validity of the conclusions, particularly the parts about what their climate change models can predict. (According to the report it's not much because of our inability to model clouds properly.)

I see what points the article is making, but it seems more like politics to me than trying to inform me of the truth.

No, it's a hilariously disingenuous article.

As far as I can see it's tortuously misquoting this:

So thermosphere temperatures will cool as a result of the current solar minimum, which we get on an 11 year cycle, and thanks to the TIMED satellite we have data of a complete cycle for the first time.

Course even as the thermosphere cools, surface temperatures are still rising.

Searching for source brought up a veritable sea of conspiracy theory sites and garbage like David Icke.

The key sentence from NASA: "High above Earth’s surface, near the edge of space, our atmosphere is losing heat energy." In other words, less heat is leaking up from surface level to the edge of space.

The heat is staying down here instead.

Is there an explanation for that? It sounds counter intuitive that the heat wouldn't transfer and stay at the ground of all places. Or, to put it another way, has that always been the case, or is that a new thing, that the heat stays down here?

I have literally no knowledge about any of that, so don't take my question as anything but me not knowing and wondering, please.

It's not a new thing, in principle, just something that's changing.

Some materials transmit heat better than others. If you change the chemical composition of the atmosphere, you change its heat transmission characteristics.

What we're doing to the atmosphere has several effects, one of them is trapping the heat from sunlight a little more efficiently. Of course that means that the temperature outside drops. If you insulate your house better it'll grow warmer inside and the outside walls will cool down.

https://en.wikipedia.org/wiki/Greenhouse_effect BTW.

To be honest, this always seemed more likely.

Global cooling was the dominant theory from the time investigation of greenhouse gases began in the late 19th century up until the late 1970’s.

While the Venus-like future of Earth is entirely possible, there seems to be far more evidence of planets with damaged atmospheres becoming too cold / losing entropy.
