There is no doubt whatsoever that adding CO2 to the atmosphere has a greenhouse effect, that the amount of C O" in the atmosphere has increased considerably in recent history, and that there has been a degfree of global warming.

The only argument is about whether this is the primary cause for global warming, and whether human activity is te primary cause for the CO2 increase.

Whatever the truith of that, pretty obviously pumping massive quanitities of greenhouse gases into the atmosphere seems a very bad idea in the circumstances
