Not sure why it matters that the warming may be largely from lows. Warmer is warmer. High lows means fewer mornings with frosts and freezes that kill bugs. One could argue that higher lows has more of an impact on that environment than higher highs
You have called for a cool summer every summer for the past 5 years and it’s never been correct. I believe one summer you even said 0 90 degree days or something. You must hate the heat or something lol
