I'm just reading about the dreadful flash flood in Texas and all those poor little girls who have drowned. So sad.
But, just as endless school shootings make no difference to America's attitude towards guns, I don't think this will change many people's minds - and especially Trump's - on climate change. Deniers will continue to argue that flash floods have always happened, as have wildfires, without any recognition that the frequency and intensity of these weather events are affected by human driven climate change.
So
YABU. - this will be a wake up call for the US government
YANBU - the US will still refuse to work towards carbon reduction/net zero
