I trust the chart.
Actually, the question was not did you trust the chart. We know that. It is central to your argument. The question was why do you trust the chart. It directly contradicts your belief that all scientist are lying.
Is this like Schrödinger’s cat where something can be true and not true at the same time. It just seems to me that if it is the case that the temperatures in the chart could be true and not true at the same time, the proposition that polar bears might go extinct if it gets too hot could be true and not true at the same time. That way we wouldn’t have to say the oil companies and the scientists are lying. We could say the oil companies and scientists are just saying things which are true and not true at the same time. It would just depend on you quantum state at that moment. Nah.
