Cow flatulence, gas emissions much worse than thought - boffins

Physicists, chemists, and geologist need to hear about your new discoveries. I look forward to reading your papers when you get them published. I assume your doctorate is in physics?

Re: Serious question

'm using 500 Watts of heat plus another 500 in other appliances. I use no AC in summer. My windows in the heated portion are argon filled and coated. I would think that is not too bad for a 460 M^2 (5000 2^foot) house when it''s -5º C outside, in a 1899 house.

Re: Bottom up approach

I saw that too, but cows belch methane. Very little come out the back-end.

CO2 has the structure o, O-C-O which make it very good at rëemitting certain infrared (IR) frequencies. Methane (CH4) has a different structure that makes it very good at sending IR heat back to Earth at frequencies different then CO2. It is because no other atmospheric gasses, except some CFC's, transmit in those frequencies that make CH4 such a strong "greenhouse gas." Picture it this way, take a piece of glass 2 cm thick that is invisible to IR and then coat one side with a fume of shiny gold a few atoms thick —they do such for high-rise buildings—. and see how 98% of the IR is reflected. The gold on the glass would be only a few 10 millionths of the glass, but the glass does not react to that wavelength and gold does. Because of that CH4 is much, much stronger then CO2 and CO2 is much much stronger then the IR transparent nitrogen. Side note, the sky is blue because nitrogen is effected by high frequencies.; if it were mostly CO2 it would be brownish-red. I could show how the basic physics work in less then six hours, which is too long for here. Please read up on it, It really quite interesting. Uni of Chicago has some free online lecture on this.
