  1. I don`t agree with all that Al Gore says,I have a lot of information that he lies.Perhaps the biggest contradiction in the speech of Al Gore are not the substantial scientific errors contained in his Oscar-winning documentary "An Inconvenient Truth" but his own style of life, the private jet of former U.S. Vice President delivered some 20 tons of CO2 in a week on tour Spain. Gore moved to a modest Gulfstream from Asturias to Madrid, from Madrid to Paris and from Paris to Madrid, from Madrid to Asturias and Sevilla. If behind the warming of course find the hand of man, the former politician was safe.
    If he want to protect the environment he shoul travel in a normal plane or travel by public transport.
