    In a controversial new study, University of Waterloo, Ontario, Canada, Physics Professor Qing-Bin Lu contends that the world has actually been cooling in the years since governments clamped down on aerosol gasses, which he believes are the real culprit for climate change.

    “Conventional thinking says that the emission of human-made non-CFC (chlorofluorocarbon) gases such as carbon dioxide has mainly contributed to global warming,” Lu said.

    “But we have observed data going back to the Industrial Revolution that convincingly shows that conventional understanding is wrong,” he said.

    Professor Lu’s report, published in the International Journal of Modern Physics B, challenges the widely held notion that carbon dioxide emissions are the main cause of human-driven climate change and instead suggests that CFCs have been to blame for a trend of anthropogenic global warming from 1970 to about 2002.

    CO2 and other molecules in atmosphere which start to vibrate easily(in other words warm up) when exposed to sun light(more exactly on infrared and near infrared) does not cause global warming, BUT they make it worse(without CO2 in out atmosphere earth would be about 33C colder, pretty much impossible place for any complex life to form), no question about that. its sun that gives the heat and stuff like CO2 that absorb the energy and thus warm up earth instead of letting it go past them and reflect back to space from clouds, seas and to lesser extend from other stuff the light hits. ozone on the other hand absorbs UV light, which is pretty damn harmful for people(and other animals, as well as for plants) in too high amounts. CFCs destroy ozone and the amount of ozone is dependent on the temperature in the stratosphere. Co2 warms up stratosphere, and thus forcing ozone away from where it should be.

    The real cause of global warming is the decline in the number of pirates in recent centuries:

    … a theory is primarily a form of insight, i.e. a way of looking
    at the world, and not a form of knowledge of how the world is….
    .. all our different ways of thinking are to be considered as
    different ways of looking at the one reality, each with some
    domain in which it is clear and adequate….
