How is climate change connected with physics?

I have a projects, and i need to know how climate change and physics are connected with each other?

The two cannot be separated.

Don't listen to this nonsense about "alarmunists" blaming everything on global warming. To say that something could be caused by global warming, you have to be able to answer, how.

And to be able to know anything about global warming, you must understand physics. Start with the laws of thermodynamics

and infrared spectra of greenhouse gases.

Kano: I have shown you the changes in outbound radiation before that have occurred within the frequencies that water vapour does not interact with. Water vapour is a fairly weak absorber in the same bands that CO2 absorbs at. The lines in which it does absorb at are fairly sparse compared to CO2 even within the band that water vapour absorbs.

No doubt you will ignore this once again. Before you start telling others that hundreds of years of atmospheric physics is wrong and thousands of scientists and scientific organizations are just in it for the money I would suggest you first learn how and why as well as looking at some actual data. and I don't mean something off your favourite blog.

Probably everything is connected to physics. With Global Warming what you have is the world warming very slightly. It adds a degree or two to the entire Caribbean Sea - and all that energy over such a wide area creates incredible storms. It also adds that extra heat to the oceans destroying the reefs.

Blind stupid right wingers get a big kick out of denying this is happening - but it's coming your way real fast and it's all physics.

Pay attention to the sociey's position on climate change

My brother who is a chemist seems to think everything is about chemistry and since I am a geologist, I tend to think of everything under the geology umbrella. Climate is part of the earth after all. I suppose physicists may try to include just about everything within their umbrella. Physics is the only realm of science that has any support of AGW. Since many hot and cold periods happened in the past, geologists are typically skeptical of significant AGW. Basically AGW is primarily supported by models using principles of physics.

Supposedly the physics is, CO2 allows short wave radiation from the sun to pass through the atmosphere and warm our surface, but blocks a very small amount of long wave radiation from earth radiating back into space (a very small frequency of LW heat that is) causing our climate to warm.

But seeing that 70% of our greenhouse gas is water vapor which partly overlaps the frequency of CO2, this makes CO2 a rather insignificant warmer, the theory was the small amount of warming caused by CO2 would cause an increase in water vapor ( the stronger GHG) therefore heating our planet.

This though has not happened, water vapor has not increased, and anyway water vapor not only warms but through it's transport of latent heat (evaporation) in our atmosphere, it also has cooling effects.
