Northern Hemisphere Pollution a Cause of '80s Africa Drought

vinces99 writes "Decades of drought in central Africa reached their worst point in the 1980s, causing Lake Chad, a shallow lake used to water crops in neighboring countries, to almost dry out completely. The shrinking lake and prolonged drought were initially blamed on overgrazing and bad agricultural practices. More recently, Lake Chad became an example of global warming. But new University of Washington research shows the drought was caused at least in part by Northern Hemisphere air pollution. Particles from coal-burning factories in the United States and Europe during the 1960s, '70s and '80s cooled the entire Northern Hemisphere, shifting tropical rain bands south. That meant that rains no longer reached the Sahel region, a band that spans the African continent just below the Sahara desert."

    The above comment is what you'd call a "double-entendre" -- on its deceptively harmless surface, the poster asks that the United States cease generating power through the combustion of fossilized Carbon.

    However - "coal-burning" is also a slang term for interracial copulation, aka black-on-white miscegenation, and so white women who sleep with black men* are disparagingly referred to as "coal-burners."

    * Having the soft internal pink of their conches pulled inside out by a thick turgid big black cock, that is.

    Your repugnant, rotting cock will soon succumb to the warm embrace of my feces! Yeah, just keep stabbing your disgusting cock into my foul asshole, and make sure you stab it right through my soft, warm feces! It's a feces fiesta in here! What say you?

    Well, you can think about it it in realistic terms instead. Even if US adopted economy crushing policies to reduce emissions to insane levels it won't make an iota of difference compared to the 800 coal fired plants that India and China are building or planning. Furthermore, while these coal fired plants undoubtedly raise C02 levels the science of climatic feedback is so poorly understood it is not known whether those will be significant compared to the most significant 'greenhouse gas' - water vapour. In short, you'd be happy to destroy a productive economy for not real gain based on superstition peddled by alarmists. Despite what they say, the science is not settled and as time goes on it appears reality is trending towards the skeptics projections rather than the alarmists ones. You can mod me down for disagreeing with me, but you can't change the data that shows after a spike a decade ago global warming has slowed down to a negligible rate in the Northern Hemisphere and there is cooling in the Southern Hemisphere (where I live). I don't ask you to believe me, I ask you to check the data yourself before calling for deindustrialization.

    Um, perhaps you ought to check out a real history book some time. African slavery was run my Muslims. American businessmen were just one of the customers. Even today there is enslavement of Black animist and Christian Africans by Arab Africans in Sudan. Look on YouTube for "Simon Deng" if you want to see the personal testimony of a Sudanese man who escaped his Islamic masters. Sure, the imperialist European powers brought much bad in addition to the enormous good - but let's put the slave situation into historically accurate perspective, please. Especially since slavery still goes on today - and once the Caliphate is re-formed (by the Muslim Brotherhood, and their Salafi, Wahabbi and Al Qaeda mates) and an "Age of Jihad" is formally declared then we'll again see mass slavery again (non-Muslim women being espeicially prized as sex slave concubines with no rights). Saudi Arabia did not ban slavery until 1962 (and it still continues underground). In Britain there have been an epidemic (at least 60 gangs in recent years) of Muslim men deliberately grooming and drugging white British girls (around 12 seems to be the target age group). This article provides background about how slavery is explicitly permitted by Islam (and unlike the Abrahamic faiths) is still considered canon today. Here's an article that discusses the modern Islamic rulings that permit slavery (not just Qur'an 4:3):
