  1. We are told that CO2 causes global warming.

    The Atmosphere is made up of 380 parts per million CO2

    Of this, only 4% of atmoshpheric CO2 is man made... that is 80 parts per million.

    To put that in perspective, take a regular houshold bucket filled with water. 80 parts per million of this is about 1/2 teaspoonful

    So, to answer your question "What is mans contribution to global warming?"... very nearly nothing.


  2. I think the earth is cooling. I'm not kidding.Look up the earth's average temp by year and see that we now have three years in a row of the temp going down.

    If we get six in a row or at least seven out of ten showing the temp going down then we definetly are in a cooling trend and confirms all along what some of us thought and that is that man has had nothing to do with the earth being a little warmer in recent years.

    It can all be attributed to solar activity.

  3. LOL at the above answer....spitting???!!  AGW theory knows no bounds!

    Man has no effect upon solar activity (the driving force of climate change).  Research the "Modern Maximum" to see how the Sun is responsible for the latest warming trend.

  4. nothing

  5. 70 million TONS of CO2............. a DAY! That's all.

  6. They are the major factor.

  7. Global Warming isn't real. I can't beleive theres a category for this. Mother Nature is Mother nature, you cant change it, and there's no stopping whatever happens, its all a cycle.

  8. At present 27 Billion tons of Co2 per year

    And then theres methane

    http://en.wikipedia.org/wiki/Methane#Emi...

    a little over half is produced by humans.

  9. we man kind are the only factor.

  10. I blame mostly politicians for their contribution of HOT AIR!

  11. Not as much as Natures.

  12. like throwing trash, spitting, using plastics, deforestation etc..... there are so many!!

  13. mainly driving and littering is what i would say

  14. This is what the Bush admin. says about AGW!
