It takes a lot of heat to wipe out the arctic ice that has rapidly deteriorated in the last few decades. We know the CO2 has been steadily, rapidly rising since we started measuring it in HI too.
It’s pretty obvious we’re trashing the planet with our excessive waste, pollutants, GHGs, and plastic. It doesn’t need to be a political issue. I don’t even care what the global temps are. Look around. The planet looks like trash compared to 300 years ago. We should just simply be striving to be as “green” as possible.
