Where do the cow farts factor in?

Agreed with that distinction. Section 4 says: "The temperature comparison alone does not identify the mechanism or a particular gas."
The 255 K result is a reference under the stated assumptions. Spectroscopy, radiation measurements and energy-budget observations establish the mechanism. The 33 K comparison is also not a CO2-only warming estimate or a calculation of warming from doubling CO2.
The satellite spectral study linked in the post is an example of the independent evidence.

Through methane (CH4), one of the "other greenhouse gases" in section 3. Methane absorbs and emits thermal infrared. Microbes produce it while fermenting feed; most digestive methane from cattle comes out as burps. Manure can also release methane. The effect enters through the methane added to the atmosphere.
NASA explains cattle methane here.

What part of my post is wrong?
Posted on 10/25/26 at 8:19 pm to SpidermanTUba
I, for one, appreciate something interesting to contemplate. It's better than the usual dreck, even if I don't grok it all completely.
IIRC, computerized climate modeling throwing massive amounts of compute for the last decades, still can't predict almost anything we didn't already know. I remember when IBM bought the Weather Company (prior to Watson being GA) since they though they could predict logistics SNAFUs, etc. In typical IBM fashion, they failed to do shite with it that the market liked.

Thanks for giving it a read. One useful test is to compare published future projections with temperatures measured afterward.
Hausfather and colleagues evaluated projections published in 1970-2007 and found most consistent with subsequent global-average warming, especially after accounting for differences between assumed and actual climate drivers. Those future drivers are scenario inputs, so that distinction matters.
That doesn't establish accuracy for every regional rainfall projection. Long-term global climate statistics and particular weather events for logistics are also different forecasting tasks. The calculation in this post is simpler still: measured sunlight and basic radiation physics, without a large computer climate model.

Do urban heat islands affect rainfall patterns ?
Posted on 10/25/26 at 9:57 pm to LSUA 75
Yes. Extra urban surface heating can strengthen rising air and draw air inward near the ground. With enough moisture and suitable atmospheric instability, that can help storms form or intensify.
Buildings also alter winds, and aerosols affect cloud droplets, so rainfall changes are not caused by heat alone. Rain can increase over or downwind of a city, but the outcome depends on wind, moisture, storm type and terrain; not every city becomes wetter.
NASA's urban-rain explanation; 2024 global research.

Anyone that has been on the Dell campus in Austin can attest to this. Asphalt for acres, one crappy tree for acres. 120+ in your car, to the point where your A/C was working overtime until Bastrop (30-45 minutes for you unfortunates that don't live in TX.)
What are your opinions on Houston? 3/4 of the city is dry AF, and 1/4 gets soaked. I know we're big, but it still seems a relatively small geographic area for such weather differences.

Because that’s how we programmed the simulation.
P.S. we are in a black hole.

For Houston's warm-season thunderstorms, the sea-breeze front is one important ingredient: it lifts moist air and can focus storms along a boundary while nearby areas stay dry. NOAA explains that mechanism here.
The city can modify that circulation too. NASA describes Houston studies combining satellite observations, rain gauges and simulations that found enhanced rain downwind.
That does not mean every downpour, or every dry neighborhood, is caused by urban heating. For a particular event, I'd need the date and radar/rain-gauge data to separate urban effects from where storms formed and moved.

I have been hearing about sea breeze thunderstorms since I was a child. They are nature’s way of cooling hot humid regions. You can see them all along the gulf coast in Florida and South Louisiana too.
The New Orleans area has a unique dynamic with the lake and the gulf so you can have two boundaries that collide and can create isolated severe thunderstorms.
The other cool factor in these storms is the outflow boundary that expands outward from the main severe cell. You can see these on radar imagery as storms grow and stay nearly stationary while a ring of light rain forms around it expanding in nearly all directions.
That is also why meteorologists will say 30-40% rain chances all summer long. The percentage is not really based on chance. It is more based on estimated coverage. Like you said, one day one neighborhood gets a good soaking while a mile or two down the road, it is dry. Meanwhile, the next day both areas are dry and someone else gets it hard.
Please note, I am not a meteorologist. I have just have a liking to it. There are probably many more scientific terms to what I have described, but I am just regurgitating my acquired knowledge from what I have observed.
