As a matter of fact, it is.
The total amount of CO2 emitted by the Siberian Traps volcanic episode has been estimated at 6-20 x 10^16 mol, or 2.6-8.8 trillion tons CO2.

Since we're putting out about 35 billion tons a year, that equates to 75-250 years' worth of current emissions. And remember, it took about a WHOLE MILLION years for the Siberian LIP to put that into the atmosphere.

So yeah, very comparable. Dumbfucks like you have this idea of volcanoes as being these monstrous things beyond human compare, but it turns out that when it comes to CO2 emissions, humans are the best at pumping it out.

>Common traits=/=common ancestor.
Luckily, molecular evidence tells us that all apes (including humans) share a common ancestor.

>making excuses, throwing out big numbers, and calling names
you don't have to get salty just because you don't know anything about evolutionary timescales, and think that hominids speciate faster than trilobites. are you really that upset about me throwing out big numbers? Homo sapiens HAS been around for ~280 kyr; sorry if that's too big a number for your mind to comprehend

>why not say what you meant?
I did. You responded with an unrelated comment out of left field, as if I would fall for that ruse.

>hurr the reason that humans can do a bunch of things other apes don't is because their thumbs are better
yes, that's it! it's the thumbs! not the intelligence, language, or advanced culture!

>dancing around the issue and namecalling again
there IS no issue. you're claiming that "humans made this hand-axe" is equivalent to "a supernatural being made everything". and you're whining when I point out how monumentally stupid this statement is.

>It's called "common sense."
"common sense" also tells you that the Earth is flat, that water warms up when it's boiled, that rocks can't float in water, and that solid rocks certainly can't flow. There's nothing rational about it, and it is NOT a substitute for actual knowledge.

>Hasn't rhrre been a debate over whether "homo" habilis was homo or australopithecus (southern ape)?
Homo habilis is a descendant of Australopithecus, but its features clearly support grouping it with Homo. Yes, paleoanthropologists have argued extensively about this.

I'm having trouble figuring out how to write this function to use with Euler's method in matlab, could really use some help if anyone can figure out why the fuck it gives me pic related when trying to solve with ODE45:


function y_ut = bjODE(t,dy)

W = 686; %gravitationalforce(N)
c = 0.227; %constant for air resistance(kg/m)
D = sign(dy(2))*c*dy(2)^2; %air resistance
B = 10*(dy(1) - 150); %force affecting jumper if x(t)>150m
m = 70; %JumperWeight(kg)

if dy(1) < 150
F = (W-D);
else
F = (W-D-B);
end

y_ut = [ F/m;
dy(2) + dy(1)
dy(3) + dy(2)];


Original ODE's are:
x''(t) = (686 - 0.227*x'(t)^(2)) / 70
and when x>150:
x''(t) = (686 - 0.227*x'(t)^(2)-10(x(t) - 150)) / 70
