Carbon Dioxide is what plants need to live. I can't figure out what your point is.
Then burn and be marry!

We will find out who's right!
Matthew, if you truly believe your bullshit. I expect you to hand your computer over to a sceptic. Leave the city and begin a pastoral life with no electricity, no cars, no lanterns, only candles made from wax.
Anything else and you're just a ******* poser.
Mr. Westwall, only a faker like you would build this strawman. From the time of Arrhenius, in 1896, we have known that the GHGs are neccessary. Without them, the oceans would be frozen down to the equator. However, we also know that a very rapid increase in GHGs results in some very negative effects. Such as a rapidly and unpredictably changing climate. On a planet with over 7 billion people depending on an agriculture that depends on a stable climate, an unstable climate can have some very serious results. Also, the increasing acidity in the ocean, the increase of precipitation events and drought, and the increase of intensity in both, are not doing any of us any good.
As far as your silly 'pastoral life' crock, when you are reduced to making such accusations, you have lost the debate. Phd level? Bullshit, about 7th grade level arguements is what you are engaged in.
