No matter what side of the fence one stands on climate change, all can agree that spewing mercury, lead, carcinogens, and other forms of noxious particulate matter into the atmosphere is hazardous to health.
Methane (CH4) is over a magnitude more destructive than CO2. Methane comes from burning off fossil fuels, human and animal waste, landfills, and other sources.
Nitrous oxide (N2O) is far worse than methane. It lingers in the atmosphere for at least one hundred years.
Chlorofluorocarbons (CFCS) are several magnitudes worse than methane.
CO2, CH4, N2O, CFCS are known as "greenhouse" gases. The amount of gases that enter the atmosphere have been tracked for decades. Data is data. It appears that data analysis is at the heart of the climate change controversy.
Tons of heavy metals such as mercury and lead are released into the atmosphere every day.
So whether or not one wants to argue about climate change, immediate public health concerns as well as environmental impact (steadily lower pH levels in fresh and salt water bodies) are quantifiable.
I think switching over to other energy sources is a win win regardless of whether climate change is a hoax or not. The economic benefit of transforming energy reliance from fossil fuels to renewables is unfathomable. R &D, new infrasture, manufacturing, installation, maintenance, and unforeseeable positions will be created and economies will grow.
