at 12:58 am chooses to state his position on the greenhouse effect in the following 134 word sentence: «But given the [1] basics of the greenhouse effect, the fact that with just a very small percentage of greenhouse gas molecules in the air this effect keeps the earth about 55 - 60
degrees warmer than it would otherwise be, and the fact that through easily recognizable if [2] inadvertent growing patterns we have
at this point probably
at least [3] doubled the total collective amount in heat absorption and re-radiation capacity of long lived atmospheric greenhouse gases (nearly doubling total that of the [4] leading one, carbon dioxide, in the modern era), to [5] levels not collectively seen on earth in several million years — levels that well predated the present ice age and extensive earth surface ice conditions — it goes [6] against basic physics and basic geologic science to not be «predisposed» to the idea that this would ultimately impact climate.»
