Since all this hysteria has started, every envirowhacko is staking man's viability, on a mere blink of an eye of data. There is overwhelming evidence that in history, the earth has been much much warmer, and much much cooler. Even as late a 1000 years ago, the global climate was warmer, even the Vikings colonized Greenland.
