As children, many of us played the game "telephone" - a message is whispered from one person to another, which is constantly distorted as it goes down the line. In this game, people's perception and understanding is more important than the original message, but as US Secretary of Defense James Schlesinger said in 1975, "everyone is entitled to his own opinion, but not to his facts."
Today, this statement applies to climate change. While there is broad scientific consensus that human activity has contributed decisively to the warming of the atmosphere, oceans and land, causing large-scale changes in a very short time, public opinion is less clear. At least 97 % scientists agree that humanity is contributing to climate change, but the same cannot be said for society as a whole.
