Before industrialization, the amount of co2 in the atmosphere was about 280 parts per million, or PPM. Today, it is 360PPM, nearly a 33% increase, and is not attributable to volcanic activity, or an organic source. Those who call our contribution minuscule are plain liars, nothing more. If they are not, I suggest they propose an alternate source of nearly a third increase of CO2 in the last 100 years, during which volcanoes were quite well documented, that fits the available facts.
I didn't make up the elephant and mouse analogy used earlier, and I didn't specifically call you a liar in that paragraph. I said that if you spread that particular lie, you're a liar, and that's what started this whole mess.
On the other hand.
The Heartland Institute, and CO2Science.org, are professional liars. Likewise, if you spread the lies of professional liars, you are a liar yourself. It's a statement of fact, not a judgment call. I'm sure you really believe it yourself, but that doesn't alter the equation.
You also called Environment and Climate News a reputable science publication, which is a lie, and when called out you dropped the subject.
