Why the Sun, Not CO2, Heats the Oceans Revisiting the Debate: Does Greenhouse Back-radiation Warm the Oceans?
This is the transcript for the video published on youtube
https://youtu.be/61VxYVIHW-UWelcome everyone.
About a decade ago there was a heated and unresolved debate on whether infrared back radiation from greenhouse gases is heating the oceans. Because infrared penetrates less than a millimeter into the ocean's surface, many skeptics argued it is impossible to blame rising CO2 for ocean warming. However, several prominent skeptic scientists, people who I have great respect for, also weighed in arguing it was silly and useless to argue infrared heat can't warm the ocean.
After analyzing the physics detailed in this video, I’m convinced it is solar energy that drives the observed ocean heating, and any infrared ocean heating is insignificant at best. If this analysis holds, it is another significant strike against the prevailing CO2 driven global warming theory
To ensure lay people are brought up to speed, here's a quick summary of where consensus climate science stands today.
Climate scientists construct models of the earth's energy budget. The amount of energy absorbed by the earth or emitted back to space each second, is measured in Watts and is standardized for an area measuring one square meter. For those unfamiliar with that measurement, simply understand that more Watts signify more energy.
The energy budget illustrated here was published by Stephens 2012. Others have slightly different numbers, but this illustration is one of the best because it is one of the few that lists the range of uncertainties in their measurements.
Because the sun's surface is so hot it emits high energy shortwave radiation. On average the earth warms as short waves add 75 Watts to the atmospheric water vapor while the earth's surfaces absorb about 160 Watts, totaling 240 Watts that are heating the earth's daytime climate.
According to the Stefan-Boltzman law, and remember scientific laws are undisputed, when a surface is heated it causes that surface to respond immediately by releasing an equal amount of energy from that surface.
