This isn't a rip and paste, this is just me having fun with some numbers.
Few people comprehend the scale of Man vs the Earth vs the Sun. The numbers are so staggering that it's truly impossible to get a clear reference point in your mind. Using ratios however, it is possible to comprehend it better.
First, some raw figures:
The mass of an average Housefly :0.0000115 kg
The mass of an average Human :62 kg
The mass of Humanity (2015) :455638000000 kg
The mass of the Pacific_Ocean :710000000000000 kg
The mass of the Earth :5977200000000000000000000 kg
The mass of the Sun :1988000000000000000000000000000 kg
Now, let's play around with some ratios to help better put these numbers into perspective.
Humanity is to the Sun what X is to the Pacific_Ocean:
Humanity x Pacific / Sun
455638000000 x 710000000000000 / 1988000000000000000000000000000 = 0.00016272785714285714 kg
So what does this mean ?
All of Humanity, is to the Sun, what 0.000163 kg of humans is to the Pacific Ocean. Keep in mind that 0.000163kg is 163 mg. That is about the weight of 10 large houseflies.
So do you really think 10 houseflies, just doing what houseflies do to survive, would have the power to change the temperature of the entire Pacific Ocean ?
You pretty much have to think this would be possible, if you believe in Anthropogenic Climate Change.
Ok, forget the Sun... let's consider the Earth instead.
Humanity is to the Earth what X is to the Pacific:
455638000000 x 710000000000000 / 5977200000000000000000000 = 54.122830087666465 kg
All of Humanity is to the Earth, what 54kg of Humans is to the Pacific Ocean. Keep in mind that 54kg is 119 lbs.
So do you really think a 119 lb man, just doing what a man does to survive, would have the power to change the temperature of the entire Pacific Ocean ? You pretty much have to think this would be possible, if you believe in Anthropogenic Climate Change.
