...that Mr. Hansen has hard evidence that actual percentages of CO2, methane, and other greenhouse gases have increased in the atmosphere? I'm not talking about cojncidentally matching the industrial revolution, I'm talking about hard evidence of percentages of these gases in the atmosphere say, 50 years ago compared to today. Because in all of the hyperbole, yelling, threatening, and name calling, I have yet to see those figures. That is what it would take to convince this particular individual that rising atmospheric temperatures are related to greenhouse gases.
Please, no accusations of being a right-wing nut. I just don't jump on any bandwagons until I'm sure of the facts.
