I think that would be a better question.
But in response to your question.
1. Temperature. This goes down when the CO2 level goes up, as it is now. However, it sometimes goes up when the CO2 level goes up. It is a very confusing subject. Some scientists, like Al Gore, make a lot of money from the confusion of the subject.
2. Humidity. This makes you sweat when it is high and the temperature is also. In the desert, there is a very low humidity. That is because no one lives there and therefore there is no one to sweat and raise the humidity.
3. Altitude. The higher up you go the more you can waste precious fossil fuels without people complaining. President Obama is one of those high level people.
4. Oceans. This is where all that Global Warming is hiding. Stay away from the oceans or AGW will reach out and getcha!
5. Latitude. This is very important. The further you get away from the Equator, the less you need refrigerators. I think this is a conspiracy between GE and Amana.
6. Taxes. The higher they go the better our climate will be, or so they tell us.
Political scientist want us to think CO2 is bad. But in reality, CO2 is the sweetest of any waste discharge on earth, the sweetest!
Political scientist also want us to think O2 is bad. However it is the opposite in many ways to CO2. O2 likes to turn whatever is sour into CO2 or as sweet as possible, anyway which way it can.
My climate change 6:
1. Water conditioning chemicals, like Chlorine, kill the Ozone protection layer as it ascends. We were told Freon does it. Fact is, Freon converts to Chlorine as it ascends with the earth's dust. This depletion then has a runaway cycle as it is fed by the earth's dust.
2. Political scientist want us to believe cars and trucks are bad. They even will convince the unknowing that trains are bad. But can you imagine where the earth was with all this atmospheric waste when the earth was in its prime a million years ago? Cars and trucks only expel while they are fired up. Beasts of burden and supply do not turn off until they quit breathing and their bodies finish decomposing.
3. As the earth turns there is a dissimilar friction of the various surfaces on the earth. This causes a turbulence that prevents the stagnation of the air. We like to call it weather.
4. The earth's magnetic core has a circulation that is also stirred by the earth's turning. This core has an unbelievably gigantic electrical current. This electrical current affects the solar winds which also influence our climate. Even if you are having trouble biting the CO2 baiters, this one is the grand daddy of them all. Look into it!
5. Deforestation has been going on ever since man has really become a dominant species on the earth. That human dominance is what is behind every single, insignificant "Warming Baiter" as with all Master baiters.
6. Me? Earth cycles? You? Aging Sun? Aging Earth? Brilliant faunas? Blowing Whales, or the lack thereof? Oh, where would we be without something to complain about and scam others into lining our pockets?
As you may have noticed, Yahoo Answers does not require its answerers to know anything about science. Here are some better sites.

But factors that do effect climate include
1. Altitude
2. Latitude
3. Distance and direction from the ocean
4. Greenhouse gases
5. The Sun
6. Volcanoes
