When did mankind start Anthropogenic Global Warming on a mass basis? I'd say the 1800s Industrial Revolution.
Pretty much, according to ice cores
Fun, but unrelated fact about ice cores: You can see a giant spike in lead content when leaded gasoline hit its peak followed by a quick drop in lead.
You know where else there's a lead peak (though not NEARLY as drastic)?
Roman times, when they were smelting lead for pipes
>hubris to say that man is causing it
This argument is fucking retarded
Never before in Earth's history has this much carbon been released into the atmosphere this quickly.
The fastest previous carbon release took place over several thousand years, not several hundred.
The Earth simply can't release carbon that fast, it's absolutely our fault.
