Global Warming?

Question

How are transfers of ebergy(radiation, conduction, and convection) and greenhouse gases all connect?

i mean how are all of them connected? sorry!

Answer 1

In terms of green house gasses the important note is that radiation from the sun passesses through them at some angles allowing it into the atmoshpere however some of it cannot escape because it is reflected back into the atmosphere resulting in a form of energy storage within the atmosphere

Answer 2

There is a lot of conjecture but there really is no actual understanding of the system. There are so many random factors in the atmospheric system that not even the most sophisticated and powerful computer can accurately predict the weather or temperature even more than five days hence. Never mind ten, twenty or thirty years.

The earth's atmosphere is like a big pool of water. It constantly shifts, swirls and flows. Just look at the next weather channel coverage of a hurricane. Note down how many times they change their predictions of things like maximum winds, maximum rainfall, landfall etc. Then compare the first reports with the last. You will find that they were most often not even close. If they are close it is just chance.

The people who claim global warming will cause more frequent or stronger hurricanes do not understand hurricanes. They begin as tropical depressions over the African desserts. These are large areas of low pressure and high temperature. What makes them become stronger is not warmth but the difference in temperature. If the temperature in the West is much cooler than the storm as it moves west, the storm will be much more powerful. If the temperature to the north is warmer the lack of difference will prevent depressions from becoming storms.

They don't tell you that, though, do they?

Answer 3

A large portion of the energy from the sun arrives in the short and visible light spectrum and UV radiation. This radiation is absorbed by the ground and water and becomes heat (long wave radiation). The long wave radiation is reflected by clouds, and greenhouse gases back to the surface of the earth. It is important to note that the major component of greenhouse gases is water vapor.

Conduction is the transfer of energy from objects that are in direct contact with each other so I don't know how that would apply on a planetary scale.

Convection is the currents created by difference in density of heated versus unheated fluids. Convection distributes heat around the world through ocean currents and wind.

Answer 4

Radiation from the sun warms the earth, conduction allows that warmth to heat the air just above the ground, and convection carries that heat to higher layers in the atmosphere. Greenhouse gasses are gasses that allow this process to happen efficiently, that is, they "trap" heat close to the earth so that it cannot be radiated away (at least not quickly or easily). Hope this helps!

Answer 5

You need to use mirrors to do it but there are people who believe otherwise.
