isn’t space a lot cooler? We are surrounded by a vacuum which, by definition, should be drawing plenty of energy from the planet.
It has been said that the greenhouse gas theory is like trying to herd mice (heat) with a chain link fence (CO2)... but they will simply keep repeating their lies until they weary everyone into no longer giving a damn.
What the hell does physics and real science have to do with Man Made Global Warming?? And who in the hell does this person think he is by denigrating their religion??

Energy from the Sun does not “escape” back into space.
It is reflected. Some surfaces are more reflective than others. Most of the surface is water. How reflective is the ocean? lakes and rivers?
Clouds cover significant parts of both water and land. How much do they reflect back into space so that such heat never hits the surface? Of course, the part that doesn’t reflect is absorbed and heats the planet.
A way to cool and save the planet is very obvious. Elon Musk believes in global warming. It would be pocket change for him to launch reflective foil over the North and South Polar regions. The polar regions would cool. Ice would grow. Ocean levels would drop.
If there were a problem, it would be easily solved. No need for complex energy credits.
There is no such thing as global warming science.
There are only time series models based on fraudulent data.
Heat is the product of the interaction between radiation and any molecule that can absorb it. Since in space there are no molecules to absorb it the temperature is very cold but you will still get cooked without something to reflect or absorb the energy. There is more energy outside our atmosphere than inside it hence the conclusion that that the earth does not radiate any energy into space - it can only absorb energy. Therefore greenhouse gases do not make our planet warmer because they prevent warm air from escaping into the cooler atmosphere.
Im no physics guy though - just an electrician.
As a PhD physicist let me assure you that this is absolute gibberish, and this idiot should just shut up.
The greenhouse effect is caused by superthermal radiation (e.g. visible light, UV) being absorbed and reradiated as infrared energy. The infrared energy is then absorbed by something in its path that does not transmit infrared radation - e.g. glass or water vapor or carbon dioxide.
The greenhouse effect is why your car gets really hot in bright sun with the windows rolled up or why a greenhouse works.
Whether human generated CO2 increases the greenhouse gas effect and causes global warming is an open question, and one is right to be skeptical. But the physical principle behind the greenhouse effect is sound physics.
At the atomic/molecular level, kinetic energy would indeed govern “heat”.
To the degree (!) space is a vacuum, it is neither hot nor cold. In order for something to be either, there has to be some THING there to contain the thermal energy. Since a vacuum is the absence of any "thing," it can't be considered hot or cold.
However, a heated body in space would radiate thermal energy, which could be absorbed by nearby bodies and cause them to warm. That's how the sun warms the earth.
“The Earff has s fever.” does ‘t cover it?
No... The spacecraft in your example does not have kinetic energy while coasting along on orbit. Instead, it posses potential energy. Potential energy and kinetic energy are not the same thing. Physics, thermodynamics stuff.
No, the World Trade Center buildings had potential energy from the energy required to lift the materials. That was converted to kinetic energy when the buildings collapsed. A spacecraft moving in space has kinetic energy from that movement.
In astrophysics, heat is also called thermal kinetic energy. The atoms are in motion, but randomly. When their vectors are aligned, there is no heat but there is still kinetic energy, i.e, motion.
It was still a misleading comment, to try and pretend that infrared thermal radiation could not leave the Earth.
