Science is not done by consensus. It is done with provable facts. These people are predicting the future based on data they are putting into a computer program they came up with. Forty years ago they were predicting that there would be ice all over the planet. Twenty years ago they said there would be no more ice caps. Algore, the biggest scam artist of them all, predicted 15 years ago that the eastern seaboard would be under water this year. Just another way to separate the masses from their money. Chicken Little.
There is no way you can tell me what is going to happen 50 years from now. Even the original climate change guru, James Lovelock, is now a skeptic. Stop the hysteria.
