Let me preface this by stating I'm a big fan of wind power. A lot of our current problems in the world could be solved by simply building a shit-ton of wind turbines (thats an official SI unit of measurement btw). However... let me convince you that wind can SOLVE global warming, but not in the way you think!
First, lets look at the causes and effects of global warming. Particles that block sunlight from radiating back out into space are good (we aren't mars!), but bad (we could be like venus). Well, after 200 years of burning carbon basically in the form of fossil fuels, we now are realizing that putting 400,000,000,000 square feet of CO2 in the air eventually ads up (thats per year btw).
So. What are the effects of global warming? A DIRECT effect of more heat being trapped on the earth means there is more ENERGY in the earth's atmosphere. This means that the strength of winds/hurricanes/storms will be greater. Hurricanes and winds and so on are nature's way of balancing out imbalances in pressure. The more energy in the total system, the stronger these "checks and balances" will be. Hence, we have been seeing more tornados, and hurricanes than ever before.
There is... however... a possibility...
Energy can't be taken away, or added, which means that wind power works by taking energy OUT of the atmospheric system, and into electricity. Of course the wind is just an extension of the sun's energy (so wind power is solar power, kickin'). So while global warming will be continually adding energy to the overall "system" WIND power (besides not polluting carbon vs. fossil fuels) actually removes energy from the overall system, thereby combating some of the effects of global warming. Cool huh? Lets run some numbers.

This is a great paper on the energy involved in some of these systems.
It basically says that to warm all the Air by 1°C you get....
The Earth’s atmospheric mass is ~ 10 m of water. Heat capacity of air ~ 0.24 cal/g/°C.
Energy to raise air temperature 1°C: 1°C × 1000 g/cm2 × 0.24 cal/g/°C × 4.19 joules/cal × area Earth ~ 0.26 ×10^22 joules ~ 0.32 W yr/m2.
Energy to raise air temperature 1°C: 1°C × 1000 g/cm2 × 0.24 cal/g/°C × 4.19 joules/cal × area Earth ~ 0.26 ×10^22 joules ~ 0.32 W yr/m2.
Joules is what we want. Joules, or units of energy basically (i'm sure i'll get some heckling for that), is a unit we can compare electricity with. Follow me!

Another great resource.
This states that humans use about 15 Terawatts of electricity every year. Thats a lot.
Also... google tells me that one joule =2.7778 ×10−7 kilowatts
Take the number of joules x the number of kilowatts per joule... and we get 7.22228 x 10^14 kilowatts.
OR
722,228 TW.
So, therefore the energy it would take if we completely converted to wind power, all of humanity would use .00002 % of the energy it takes to warm the air 1 degree C.
Hummm.... and the models predict the earth to perhaps raise 5 C in the next 100 years. 2.5 is a closer estimate. Hummm... So yes, it'd offset that global warming thing, but basically i think getting rid of carbon is a "smarter" option.
Still, it was uber fun to run the numbers, and it IS an interesting thought. Feel free to rip my math appart ya'll.
Enjoy, have a great day, and may I give a shoutout to my girl Gina. Yup, hi.
Thanks,
Guthrie
