Coach seems to believe that if China doesn't do EVERYTHING to reduce emissions, we shouldn't do ANYTHING.
It looks to me that China and India are beginning to be serious about reducing pollution, but that there is no path to stabilizing the global carbon load. Even if carbon emissions are completely eliminated, some think that global warming is now baked into the system for decades or even centuries. That means you need to prepare for more unusual weather and sea level rise.
GOP climate deniers are not just against reducing carbon emissions, they also oppose infrastructure investments to reduce the risk and damage of flooding. There is probably a trillion dollars of real estate at increased risk for flooding, and tRump revoked new policies because Obama. OTOH he's keeping his federally subsidized flood insurance on Mar-a-Lago.
