“Methodolatry”: My new favorite term for one of the shortcomings of evidence-based medicine

Methodolatry: The profane worship of the randomized clinical trial as the only valid method of investigation.

The African Holocene Humid Period

 Much warmer, and wetter in Africa

How can you know what is real?

 The essential question of science, and evidence.  A place holder post for now.

The polar vortex and the weather

 If you know how to use https://earth.nullschool.net/

You can know more about the global climate/weather than most people on the planet!

You can watch the polar vortex

You can literally see how the world weather works, even in advance

Nov 18 surface temperatures

And the polar vortex "causing" it

I take on Neil deGrasse Tyson about the ocean tides

Because he is wrong about the tides

How the tides actually work

 

Meteors and returning space craft don't heat up because of friction with the air

 The heating occurs due to the object compressing the atmosphere (air) in front of it.  A fast moving object  (over Mach 3) compresses air because the air can't move out of the way, which causes the compressed air to heat up.

Anytime you compress a gas in an enclosed space it heats up.  (the opposite is also true)

It is the very hot air that glows, (it actually becomes a plasma), and the heat from that heats up the object.   

This plasma is electromagnetic, and blocks radio waves, so there used to be a "dead air time" while returning spacecraft were creating the plasma.  (see the movie Apollo 13).  Modern spacecraft bounce the signals off a satellite, above the craft, avoiding this radio silence.

Anyone explaining it by saying it is "friction with the air" is wrong

Water vapour is a clear and colourless gas, it can't be seen by the naked eye.

seriously

This is wrong

Certainly they are trying to fix some wrong and confusing info

But it is still wrong

This is correct
