A little simple math with a visual to put 350 ppm CO2 as acceptable and 400 ppm as destroying the planet (divided by 10)

CO2 is not a poison. You breathe it every day. Concentration changes things, just as your ricin example uses a toxic dosage level. At 5000 ppm CO2 causes headaches, sleepiness, poor concentration, loss of attention, increased heart rate and slight nausea. 400 ppm is not life threatening, in fact it enhances plant life. And the geologic record shows that during one of the most dynamic periods for life, the Mesozoic, CO2 rates were higher than 2000 ppm. To say CO2 has never been higher is to ignore reality from 66-250 million year ago. To say the earth cannot survive increased CO2 is a lie. Plain and simple. 40,000 ppm- 10,000 times the current atmospheric readings of CO2 may lead to brain damage and death.

May being the operative word.

You may be my new favorite poster.

Yes, because ALL OF THE SUDDEN, the carbon cycle cannot handle varying amounts of CO2

False anaolgy.

Not really no

Well first off, lets examine your statement. You comparing the Earth with the human body. And ricin with CO2.

The earth naturally produces CO2, in fact its a critical chemical compound for plant life, which in turn are critical for human life.

Ricin, not produced by the body, and serves as the absolute antithesis to the body in relation to Co2 and the planet, in that the substance inhibits the most basic cellular functions of the human body, namely cellular metabolism.

So the planet (namely its plant life), absorbing small amounts of CO2, which the planet is capable and designed to perform, is incomparable to the human body ingesting a toxin.

Do we need to proceed any further on how this is a false analogy?

Can we beat the dead horse some more so we can squeeze out a few more liberal tears?

Like what about dire hyper feedback loops?? The climate models all forecast doom and gloom! Rising waters! And socialism working.
