I have no idea how grown men can watch a kids show with such enthusiasm.
Also, how is autism linked into this?

Just ignore the title and "enjoy" the video.

| I find it extremely strange that grown men watch a kid's show about horses, with almost religious devotion.
I eat horses. I don't watch TV shows about them.

Still cheaper than annual US defense budget.
By the way, don't you remember our last talk about global warming? Here, I found something about that just a week ago.

| It is good to question science as long as the questioner understands the science in question.
Global warming has not paused. Global average air temperature has plateaued, but this makes up only a tiny fraction of the heat content of the Earth system, and is easily masked by other processes, such as atmosphere-ocean interactions. Taking such things into account, the signal of global warming is just as strong as ever. It is the earth's oceans that store the vast majority of heat, and indeed the total ocean heat content continues to rise.
For as long as we increase greenhouse gas concentrations in the atmosphere, then global temperature will increase as well. This isn't debatable. It's just simple physics.

However, physics doesn't work this way. That's the stumbling-block of the theory. Somebody may say "but see, it's only so simple, even a kid can understand that: the atmosphere is just like a thermos, if you're increasing the insulation, the temperature will rise, as less heat will give away". And just as because it's described as something so simple, it can't work this way. There's much more behind it than we used to hear.

| The sun emits mostly in the visible spectrum, approximately as a blackbody. The earth's atmosphere is transparent to this radiation, so it reaches the surface, where some of it is absorbed and heats the ground. The Earth then radiates thermally, which we may again treat as blackbody. By Wien's Law, this radiation is longer wavelength infrared. The atmosphere is partially opaque to this infrared, so some of it is absorbed and re-radiated back to the ground, thus raising the equilibrium surface temperature. Of course, one must remember that a good absorber is also a good emitter, so the upper atmosphere can radiate more efficiently to space and therefore cools. (Indeed, we observe the Earth's upper atmosphere cooling.)
That's it, that's all that needs to be said to explain it to a layperson. You can even use that understanding, combine it with high school algebra, and calculate the equilibrium surface temperature of a planet and get it correct to within 90%. Don't believe it? Here's the formula. I can derive it for you if you are interested.
Here L* is the luminosity of the star, Ab is the planetary albedo, a is the planet's orbital distance, epsilon is the radiative efficiency of the planet, and sigma is the Stefan–Boltzmann constant. Plug in values for Mercury, an airless world, and you get within a few Kelvins of the correct answer. Same with Mars. And the Moon. Apply it to Venus and you'll be under by several hundred degrees. Why? Because Venus has an enormous greenhouse atmosphere, which effectively reduces the efficiency at which it can radiate thermally. In the context of the above formula, this is like a decreasing epsilon, since we treated the planet surface and atmosphere together as a unified entity.
If you apply this formula to Earth, you'll get a surface temperature of 255K, or -1°F. Below the freezing point of water. This tells you that the greenhouse effect of the Earth raises the global temperature by about 33 Kelvin. We owe our very existence to the greenhouse effect.
Now of course we have simplified things a great deal in the above description. If you want the full understanding, and better accuracy in the calculation, then you need to account for the finer details:
The sun is not a perfect blackbody. Neither is the Earth. The atmosphere must be modeled three-dimensionally. The spectra of each of the atmospheric gases must be treated precisely. Heat transfer through the various Earth systems must be handled. The thermal properties of different surfaces must be accounted for. This is a lot of work and a lot of math, which is where global climate models come in. But again, it doesn't change the physical principles which were described above, nor does it seriously affect the results.
Now you may continue to be dumb and argue about this if you choose, but at that point I'm simply going to tell you to grab an atmospheric science textbook and educate yourself.

Hello this time to the *campers*! It is so *spicy* to be wearing new *face*. Other *campers* are changing their *face*. Instead of the probe, but now I am Orz, and soon *the change* will be complete. So much a fun *game*! It is so *silly*. Six or nine *pieces* ago, myself the Orz did not even *smell* your *level*. Now we are having great *parties*. So much great, that Orz may never leave. Never.
Careful. The PLATT Collective has spurs.
