We can sequester carbon in the soil with the right farming methods, and ranching on grasslands. Another way to is make biochar.

Re: EVs and Emissions

Tue Nov 22, 2016 1:29 pm

Natural Gas has received a lot of greenwashing and there was a failure of assumptions on the part of the scientific community regarding fugitive emissions. It was generally assumed that due to the 12 year half-life of methane emissions, they weren't a very big deal. However, by the 20 year mark, Methane (Ch4) has delivered 84 times the global warming of Carbon Dioxide. This kick-starts all sorts of other self-reinforcing feedback loops, from methane burps out of the thawing "permafrost" to off-gassing from seabed formations of methane hydrates. Methane delivers a knockout blow early, and then tapers off. Even at the statistically diluted 100 year mark, methane emissions have delivered 20 times the greenhouse effect that an equivalent amount of carbon dioxide has. This is why fugitive emissions from oil and gas operations are such a big deal, and may be largely responsible for the faster-than-expected climate change observed to date, and also explains why waste gas flares at landfills and refineries are a big improvement over unburnt emissions.

The following presentation is a first attempt at explaining this by some friends. Not professional quality, but a good effort.

Bottom line: natural gas is a false solution, and a dangerous distraction on our way to a sustainable economy.

Jay, I moved your post here as it deals more with climate change than EVs directly.

It would make my year if the gas industry packed up and left town. From the (IMO) over-sized drilling pads to fracking to pipelines zig-zagging all over the place, I've had enough (and that doesn't even include the doubling of road traffic and resulting road destruction).

I found a study on fugitive emissions a while back (even including vehicle emissions to drill and support wells), but I feel its figures are too low. Whenever they frack a well, there is a steady stream of tanker trucks going past my work for two weeks straight...for ONE well! That doesn't include the thousands of pickup trucks driving around, nearly all from out-of-state.

One only has to look at this year's CO2 cycle to see some de-stabilization. Concentrations were noticeably above the usual increase and were inconsistent (normally follows a relatively smooth sine wave).

Thanks, and yes, that Mauna Loa data is great (as long as the old gal doesn't wake up again and start adding her own emissions). The magnitude of the methane issue just hit me recently. I had thought that the Pickens Plan (as in T Boone) to shift heavy vehicles to natural gas and recharge the rest with wind was a good step, but am now coming around to the position that we should just leave it all in the ground.

The more left in the ground (across the board), the better. Although I did see my first CNG tractor trailer on Monday. Still just as noisy as a diesel, so minimal efficiency improvement if any.

Last year while driving around one evening, almost every valley I drove through smelled like gas. Talk about leaks.

Here's a good one. Sunoco is putting in a pipeline to carry LNG from Ohio to Philadelphia, likely to export it. It goes right past my work, through some heavily populated areas, and under/through Raystown Lake. Yeah, seems like a bridge fuel all right :roll: .

Keystone XL and Dakota Access pipelines one step closer. So, how can we make oil worthless?
