That's because Man-Bear-Pig doesn't exist. If he existed, Al Gore would not have to suggest we use social engineering in order to force people to stop denying his existence and claiming that Al Gore just invented Man-Bear-Pig out of thin air.
Globowarmthinkery. Doesn't. Make. Any. Sense. Whatsoever. Not a single tenet of this religion can stand up to examination. The corollaries (like "carbon emissions") are even more tenuous as assertions built upon errors.
Water vapor is what traps the earth's heat, not CO2. CO2 doesn't affect the ability of water vapor to trap heat in any way. CO2 in fact, has no effect on global temperatures whatsoever, rather the reverse. CO2 is something that changes in response to climate, not the other way around. Ice cores show that right before a new Ice Age, there is always a heat spike that results in minutely increased CO2 for a very short period of less than ten years.
