Growing certainty about global warming

A UN panel says scientists are now 95% sure that human activity is behind the sharp increase in global temperatures since the 1950s. CNN's Tom Foreman shows us at the evidence and the effects.

    Our challenge is to take action before its too late. Even if we can't reverse the course at least help make it bearable. In the drought stricken areas we are besieged with high pollen levels caused by our stressed out plants, business failures due to customers staying home, heat related illnesses abound even my yard man says he might stop cutting grass because he is having difficulty, I no only drink Gatorade because of the heat almost 100 degrees since May and still going and many folks out west have evaporative coolers which are not working this year. In a nutshell this has changed our lives and probably must move elsewhere.

    The data shows a whopping 0 degree change in global temperatures since 1996. I suppose the UN panel and their scientists are 95% sure that humans caused that drastic increase?

    So it appears that these people are preparing us for some major fundamental and drastic changes. We are all being "softened up" so to speak with this man made global warming theory or situation and the only thing that is going to stop it is to curtail the production and sale of coal, wood and oil. And it must be done immediately. And it will need to be done by force of arms. So get ready because it is people like this who are behind it. The earths climate is so dependant upon other things like ocean currents that nobody really knows what is going to happen in the long term.
    We could suddenly be plunged into an ice age where it begins to snow and doesn`t stop. Could that happen if global warming puts too much moisture into the atmosphere forming clouds that block out the sun and create a "nuclear winter" type of situation? Who really knows. .

    "We, in other parts of the world don't really care, Wolfe. You're the worst country for wasting electricity (that is where the damage is done) aqnd it's your country that has to bare the brunt of it's backlash. You waste so much and ignore the consensiquences?? Don't listen to me, listen to your so-called experts. But!! You're frying this planet with zillions of trons from outer space.'

    If we are the cause then we can be the solution. The biggest challenge will be countries like America telling the rest of the world to knock themselves out trying to change things.
