effect of increasing
carbon dioxide, lasting some centuries until fossil fuels are exhausted and a while thereafter; and this followed in turn by (c) a glaciation lasting (like the previous ones) for many thousands

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
