Methane in atmosphere today is at 2 ppm, carbon dioxide is at 420 ppm. If methane is 20 times more potent, this implies that atmospheric methane is equivalent to 40 extra ppm of carbon dioxide. If we removed literally all methane from the a

Take a walk on Mission Avenue in San Francisco then and see for yourself (actually, don’t do that). Crime is extremely rampant in US cities, and I’m not even talking about shootings here. Assaults (verbal and physical) by mentally ill (or

If you think petty crime is bad in Europe, don’t even think about visiting Americas. US cities are so much worse than almost of Europe it’s pretty shocking.

Life expectancy in US has more to do with very bad lifestyles of Americans, mostly obesity and drug abuse, than with quality of healthcare, which in fact is superior. We are great at keeping alive very unhealthy people. As a food for though

This is also how it works in US, you just go to imaging place and they do it immediately. You just have to pay for it. In countries with state controlled healthcare, service is rationed.

Money orders are $1000 maximum, and they have fee of $2.40, so you might need to pay couple of dollars extra depending on how much you owe.

The compute cost is a challenge for amateurs and Europeans. In United States, investors will throw frankly quite ludicrous amounts of money at you if you show promise.

I like your planer analogy, though it is indeed off for woodworkers, but in a way that’s rather nuanced, so it doesn’t inhibit getting the idea across to normal people who don’t know a lot about intricacies or working with wood. There are a

No, the energy doesn’t accumulate in Earth over time. Disregarding the energy of radioactive decay within Earth, the Earth is in steady state with respect to energy. All energy it receives from the Sun is radiated away promptly. The greenho

There is no contradiction between these two statements. They both say the exact same thing: if rice cultivation is in steady state, the amount of CO2 and CH4 in atmosphere due to it is constant. You next say if we change the steady state, t

by xyzzyz 4y ago
No, that’s not the case, because the methane doesn’t accumulate. If you increase the amount of rice under cultivation, the methane content in atmosphere will stabilize after around 20 years, and after that there will be no more climate chan

I do happen to remember what the climate looked like in 2010, and I very much do not believe that enormous social and economic projects are warranted to revert the state of climate by 10 years. > You appear to be a denier of anthropogeni

No, you missed the point: there is an enormous difference between methane emissions from fresh organic matter, and emission from fossil fuels. The latter accumulate , while the former do not. That’s why as we continue incrementally burning

Yes, this is exactly what I say in my comment. The amount of methane in the atmosphere is directly proportional to the input rate . That’s why, as I said, in steady state , when the we keep steady the amount of rice under cultivation, the

Thank you for redoing the math I did, and confirming I was exactly correct with figures. The increase in concentration is observable, but the impact on climate is not. Again: this increase is similar to increase between 2000 and 2020. Witho

Yes, the whole point is that it is a cycle. The fields don’t affect by much the total number of carbon atoms in the atmosphere. Without the fields, other plants would grow there, then die, decay, and release carbon into atmosphere. At bes

by xyzzyz 4y ago
Methane is worse, but it again doesn’t matter here, because the fields are in steady state not only with CO2, but with methane as well. Methane doesn’t linger in atmosphere forever, it decomposes into CO2 in a decade or so. This means atoms

Also note “of conquest”: presumably, if the purpose of Russian invasion was to just hang Zelensky and institute a regime change with government sympathizing with Russia, and not to annex any territory, that would have been OK too.
