i took the climate change quiz and got a 30%...

this is real people. the end is near. and we will never be able to stop it...

one gallon of gas burned puts 18 pounds of co2 into the atmosphere... 18 pounds. we will all be crushed under the weight of it all... women and minorities hardest hit.

[Alas Babylon!]

Amazing, because a quick Google search shows:

The weight of a gallon of gasoline is approximately 6.073 lb.

LOL!

“one gallon of gas burned puts 18 pounds of co2 into the atmosphere...”

One tree can absorb 48 pounds of carbon dioxide/year, and a ton of CO2 over 40 years.

It's estimated that each person produces just under 2 pounds of CO2/day. There are a lot of sources that produce CO2, and a lot of places CO2 gets taken out of the atmosphere. The science is likely much more complex than the computer modeling reflects. If computer modeling were that good, and could be applied to all complex biological systems, drug development would be a lot cheaper, because you wouldn't have to do clinical trials. Except, you do.

Oh my. Plant food and propulsion! A two-fer!

I've never actually done the math on this, I've only seen this Stat on left wing sites like the EPA. Too much work to do it on my phone, so this'll be rough. A gallon of gas is about 6lbs. CO2's atomic mass is 44 (C is 12, O is 16), 3.7x the carbon input. So that gives us 22lbs,assuming gas is 100% carbon, and your engine is 100% efficient in turning your fuel into co2. And then add in the additives weight, you're probably looking at maybe 15lbs of co2/co per gallon of gas. Quick Google shows mature grassland will eat about 3000lbs of co2 / acre / year. So your gallon of gas will, roughly, feed an acre of grass for about 40 hours.
