First and foremost, CO2 is plant food.

 Download This Resource
Today’s low CO2 concentration is starving trees and plants of the food they need to achieve their full growth potential via photosynthesis. Additional benefits of increased CO2:

Increased photosynthesis (“CO2 fertilization”).

Plants grow faster, and with less stress and less water.

Forests are growing faster.

Stimulates growth of beneficial bacteria in both soil and water.

More plant growth, means less erosion of topsoil.

Bigger crop yields, and more and bigger flowers.

Fosters glomalin, a beneficial protein created by root fungi.

Less water loss, less irrigation, and more soil moisture.

Increase in natural repellents to fight insect predators.

Posted a while back, but I'll repeat:
=====================
CO2 was chosen to be a climate "boogie man" because of its inability to fight back.

From "Rules for Radicals":
Rule 11: Pick the target, freeze it, personalize it, polarize it. Don't try to attack abstract corporations or bureaucracies. Identify a responsible individual. Ignore attempts to shift or spread the blame.

THAT's why they picked carbon dioxide -- it's an essential atmospheric compound of life, but it's also an ideal target upon which to thrust blame.

How can CO2 "defend itself"?

A brilliant move by the greenunists to create an "atmospheric Goldstein"...
