1) Ferguson's estimates were hugely off - so much so that they drew attention (and you may also remember me posting about it long before this news came out about him) - and this resulted in vast change for our society.
2) He was diddling with a very radical, Far Left Climate Change activist which not only puts him in a position where he might want to please her, but also indicates his politics. It brings up the potential for a motive for vast change
3) a)The results of his faulty work have had exactly the results that his Climate Change girlfriend would want - 95% less air travel, massive auto use reduction, and restriction of many freedoms required to achieve radical CC folks goals.
b) Also, the US was considered a major roadblock to the CC goals with Trump, and while other countries will simply phase back, our system doesn't allow for that easily given the Left's ability to block the Right. This has crippled us and
hurt Trump's major, indisputable success - the economy and low unemployment numbers in all groups with better wages which therefore helps to remove the CC Left's roadblocks to a Climate Change agreement.
4) Ferguson wasn't following his own guidelines - not once, but AT LEAST twice. If he were sincere about his concerns he would not have done this. If he is not sincere, then why would he be such a vocal advocate of shut down?....which
goes back to the first 3 points.
