Physics tells us there are only a few fundamental factors that drive global temperatures.
It is helpful to define what I will call the “energy-balancing temperature." This is the average global temperature that the planet’s surface would need to have in order for the rate at which energy leaves the planet by escaping into space to exactly balance the rate at which energy arrives into the planet’s atmosphere, oceans, and land.
Claes Johnson offered an analysis which claimed that the Schwarzchild equation used to do radiative transfer calculations is wrong. However, Johnson made up his own incorrect version of the Schwarzchild equation and made other errors, which render his conclusions nonsensical.
There seems to be a belief that diagrams comparing the spectrum of the Sun and the spectrum of thermal emissions from Earth's surface conceal how much longwave radiation is present in sunlight. That's not the case, but there is sometimes something a little "off" with such diagrams. In this post, I'll sort out these issues and present some rigorously correct diagrams.
"Both IPCC and NASA agree that anthropogenic CO2 is between 3 and 4% of total CO2." The person who wrote the statement above likely believed that this information counters the idea that anthropogenic CO2emissions are responsible for the the rise in atmospheric CO2 levels from 280 ppm to 420 ppm. Yet, it doesn't counter that idea at all.
A 2016 experiment by Thomas Allmendinger claimed to have demonstrated that infrared radiation is absorbed by gases such as nitrogen, oxygen, and noble gasses, thereby invalidating the status of water vapor and CO2 as Greenhouse gasses. However, the flawed experiment actually demonstrated aluminum foil absorbing radiation.
Many alleged "tests" of mainstream climate theories don't follow any scientifically legitimate procedure. So, their "falsifications" are themselves false. Here, I sketch how a proper statistical test of a scientific model functions.
Terigi Ciccone published a whitepaper titled “REVISED, WHY CAN’T CO2 AND GREENHOUSE EFFECTS CAUSE GLOBAL WARMING?” (2021). It’s apparently a “Top Download” on academia.edu. I was curious. So, I carefully reviewed it. The paper is a nice collection of many…
Recently, someone asked me, “Do you think the Greenhouse Effect is real?” I found myself answering, “I don’t ‘think’ it’s real. At this point, I know beyond any shadow of a doubt that it’s real. As real as 11+12 = 23.”
I think it's about time that I spell out how I know it...
Many explanations of the atmospheric Greenhouse effect leave people unclear about how it raises the global temperature. I’d like to look at a simple fundamental principle which sheds light on how warming happens.
How do you raise the level of something?
If we're talking about water in a reservoir, you might think the answer is pretty simple: to raise the water level, you need to add more water—right? ...
Some people are surprised when they see diagrams showing that the Earth absorbs about 240 W/m² of sunlight, but the Earth’s surface radiates 398 W/m² upward and the atmosphere radiates 340 W/m² downward to the surface. "You can’t have more power than what arrives from the Sun!”...
