The thing that I hate about this argument of &#x27;consensus has been wrong before&#x27; when it comes to climate change is that essentially, the argument seems to be &#x27;everyone always said we were pumping too much CO2 into the air and that would cause global warming and now there&#x27;s people saying that consensus is wrong&#x27;.<p>Unless I&#x27;m seriously wrong with my scientific history (and it&#x27;s extremely possible!) I didn&#x27;t think this was the case. Decades ago there were people talking about it but the consensus was that it was crackpottery.<p>However now that consensus has decided &quot;yeah, we were wrong&quot; people point at that consensus and say &quot;hey, consensus has been wrong before!&quot;. I look at that and just think... yeah, we know. It was wrong and we&#x27;ve spent a heap of time finding that out.<p>I mean, it&#x27;s not the case that 100% of people knew it as a &#x27;scientific fact&#x27; that CO2 lead to climate change and now we&#x27;re starting to question that consensus. The questioning has already happened.<p>Or I completely wrong in this?
