        We only have very accurate data for the last century or so. T he further back in time you go, the more uncertain the data is. The grey area is the envelope of all possible outcomes.

        I hate them, you showed the world what would happen and how to avoid it and they never listened but spent billions spewing out denier crap and now the Arctic is almost gone and emissions are still skyrocketing.

        But how will we know who has the most social status??? It could never work. Would you trust your financial advisor if he skateboarded to the office?
