Spain has climates comparable to Africa. And yet Africans are black and Spanish are white. How is this possible? How come the Sun is not generating melanin in the skin of the Spanish?

>Spanish are white
Not really. They have a dark brown skincolor.
>>
>>8978919
They could have developed lighter skin on their way to Spain through Europe. Or it could be completely random because that happens too.

i'm spanish and when I travel people's first guess is that I'm either german or irish.
One english guy was pretty convinced that I was german and I was just trolling.

But anyway on topic, retard OP: UV FACTOR YOU IMBECILE.
Altitude and UV factor are the main variables determining pigmentation, whereas temperature and climate can vary a fuckton based on what basically is fluid mechanics which is all kinds of fucked up.
The only exception to this rule is inuit people who didn't need to lose melanin in order to get vitamin D because their diet included plenty.

So at what age do people stop getting smarter? There's an obvious difference between a 12 and 16 year old, but what about a 16 and 18 year old?

And I'm talking the type of smarts that let you have a good understanding of STEM subjects with relative ease.

This. I'm 24 and after 2 years of stagnation my learning abilities have plummeted to below-normie levels.

there any stimulants that don't make you piss every 10 minutes? Been trying amphetamine and it's unbearable, caffeine's even worse.

Modafinil and ritalin have the same side effect?

Honestly only brianlets need GFs, don't need a GF when I can create a robot that can suck my dick. Normal GFs don't even suck dicks most of the time. Or do they? IDK I don't got a GF nor do I need one.

My friend just sent me an artwork with something drawn in that i remember seeing somewhere involving particle physics or the physics of gravity. I don't for the life of me know what its called or remember its proper context, but it's fucking with my mind.

The sphere with all the cones around it.

Is it familiar to anyone?

Will global warming create more clouds, that will reflect the sunlight, thus cooling the planet? I mean will it slow down the process of GW?
2 posts and 1 images submitted.

>will global warming create more clouds
yes

>thus cooling the planet
that's unknown, because the clouds reflect both short-wave radiation into space as well as long-wave radiation back to earth. The relative dominance between those two mechanisms is dependent on both altitude and latitudinal position and it is very uncertain which of those two will prevail in an overall increase in cloud cover.

What is certain however, is that any cooling induced by increased cloud cover wont be large enough to overcome the warming by increased greenhouse gases. We know that because increased GHG in the earth's past have always had an overall warming and not a cooling effect.

Hello /sci/,


I'm a native English speaker who didn't have a traditional education growing up; my math skills are good but I'm not very creative and my grammar is horrible. Any recommended courses to fix my grammar? And creativity? Is there any way to actually be more creative? Everything I've read basically says no/barely but I wonder if anyone here has any new knowledge.
