The Vacuity of Climate Science

cafeamericainmag.com

There has been a lot of CW discussion on climate change. This is an article written by someone that used to strongly believe in anthropogenic global warming and then looked at all the evidence before arriving at a different conclusion. The articles goes through what they did.

I thought a top-level submission would be more interesting as climate change is such a hot button topic and it would be good to have a top-level spot to discuss it for now. I have informed the author of this submission; they said they will drop by and engage with the comments here!

From your first Twitter link, the guy gets it wrong right off the bat. "How can the GHGE work after so long a night?" Because of the thermal mass of the ground and atmosphere, and the insulating properties of the atmosphere which is much thicker than Earth's, and because high winds on Venus tend to equalize day/night side temps.

This guy doesn't know what he's talking about.

https://twitter.com/_Escapekey_/status/1748317807006118335 is also cute, as growth is also visible before their claimed start of conspiracy (even on their own graph, no idea is any claim there even accurate)

Thanks!

From your second link:

A typical validation of the Stefan-Boltzmann’s law of radiation : is done by measuring the radiation from a filament of the incandescent lamp. The filament is enclosed in a vacuum.

A typical demonstration of radiative heat transfer is done in a vacuum, but that isn't a real requirement. You can instead compare the total heat transfer from a hot black plate (emissivity near 1) to the heat transfer from a hot silver plate (emissivity near 0). The black plate will have faster heat transfer despite being surrounded by the same air because it radiates more.

I'd like to see his calculations for "...the conductive and convective effects at the surface are vastly greater than the radiation; by about 240 times."

Venus has a very high albedo. Most sunlight is actually reflected away from the planet. Venus actually gets less net sunlight than earth! GHGE says Venus, without a greenhouse gas effect, should be cooler than earth!

No!!

Even if you assume the emissivity of the object (such as Venus) can be fully described in a single number (i.e. it is an ideal gray body), you're only describing the gross rate of radiative heat transfer. Any ideal gray body that was protected from conduction/convection would reach the same equilibrium temperature given the same surroundings; a high-emissivity one would absorb a lot of energy which is coming in and emit just as much, while a low-emissivity one would absorb a tiny bit of energy and emit just as little.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
