Getting Greenhouse Wrong
 

atmosphere

 
There is nothing resembling a greenhouse effect in the atmosphere. A greenhouse uses a physical barrier of glass or plastic to prevent air currents from convecting and keeping out weather while letting radiation in. There is no such barrier in the atmosphere. So why use the term "greenhouse" for atmospheric effects?

A lot of persons do not know that there is no greenhouse effect in the atmosphere. So using such terminology creates improper assumptions in their minds. It seems to tell them that heat cannot escape once it is picked up by CO2 in the air

Clear air cannot trap heat. Fakes needed to pretend that heat gets trapped in the atmosphere; otherwise, anything one molecule in 2,500 did would be too miniscule.

So fakes claim there is a greenhouse effect in the atmosphere which traps heat caused by molecules which they refer to as "greenhouse gases" or "heat trapping gases." It's total fraud.

All matter emits radiation constantly. A transparent gas emits radiation much more readily than the surface of an opaque solid, Atmospheric Radiationbecause radiation can leave from every molecule in a transparent gas but only from a thin layer of surface molecules in an opaque solid. The atmosphere would emit radiation at least a thousand times more readily than the surface of the Earth—probably more.

The atmosphere is a heat sink which picks up heat from the surface of the Earth and radiates it into space. Heat is picked up by conduction and convection as wind blows over the surface of the Earth. Once the heat is in the atmosphere, it radiates into space quite rapidly.

Just as the atmosphere radiates away heat from the surface of the earth, it would radiate away any heat picked up by so-called greenhouse gases.

The air cools rapidly when clear due to the high rate of radiation emitted from the transparent atmosphere. An overcast can trap heat in the atmosphere by reflecting radiation off of water drops, but clear sky does not trap heat.

Radiation From Atmosphere

Why didn't the fakes say so-called greenhouse gases absorb radiation rather than trap heat? Because they need a trapping mechanism to get something out of nothing, while the trapping claim is a total fraud.

The atmosphere is not totally transparent to infrared radiation. Different wavelengths go through differently, and 15-30% of infrared radiation is said to go around all so-called greenhouse gases (as stated on Wikipedia). Going around creates rapid cooling. A gate half open cannot keep in half the sheep. Each time absorption and re-emission occurs, 15-30% goes directly into space. A few cycles sends all of the energy into space by going around other absorbing gases.

Even continuously absorbed radiation doesn't take long to get from atmosphere to space. Absorbed radiation is re-emitted in 83 femto seconds on average. So radiation gets from ground to outer space in 0.5 nano seconds for the 70-85% that is absorbed and re-emitted. (saturation in 10 meters, 15 km height x 83 femtos x 4 = 0.5 nanos) (half of saturation gets half of radiation through = 4x time).

Large amounts of heat move into and out of the atmosphere constantly, as temperatures change 20 degrees or more between day and night.

These effects are nothing resembling what a greenhouse does.

Description of "Greenhouse Effect"

Here's how the Union of Concerned Scientists described their assumptions about a greenhouse effect on their web site for several years. Recently, the statement was removed.

The "greenhouse effect" refers to the natural phenomenon that keeps the Earth in a temperature range that allows life to flourish. The sun's enormous energy warms the Earth's surface and its atmosphere. As this energy radiates back toward space as heat, a portion is absorbed by a delicate balance of heat-trapping gases in the atmosphere —among them carbon dioxide and methane—which creates an insulating layer. With the temperature control of the greenhouse effect, the Earth has an average surface temperature of 59°F (15°C). Without it, the average surface temperature would be 0°F (-18°C),---

Scientists have concluded that human activities are contributing to global warming by adding large amounts of heat-trapping gases to the atmosphere.---we release carbon dioxide and other heat-trapping gases into the air.


They missed the conduction, convection and evaporation which put most heat into the atmosphere and assumed radiation absorbed by so-called greenhouse gases is the only methods of moving heat from the surface of the earth to the atmosphere, as explained here: How Could All Those Scientists Be Wrong
