This morning a Mercedes Benz, a BMW and a Volkswagen, driven by a group of “climate barbarians”, entered the Circus Maximus in Rome  led by the new “Emperor Nero” (Berlusconi). Greenpeace activists, wearing ancient Roman dress blocked the symbolic convoy, unrolling banners reading: “QUO VADIS, BERLUSCONI?” and “VADE RETRO CO2! INQUINATORES NON PREVALEBUNT” - Where are you going, Berlusconi? Go back CO2! Polluters will not prevail!
