There are four kinds of Americans: those who believe in global warming, those who don’t, those who are undecided or confused due to the conflicting science and reports, and those who just don’t care.

No matter where you fall on the spectrum, one thing is certain: There are serious political implications tied to fighting climate change that affect us all.

Although the science is far from settled, the politics associated with global warming are obvious to anyone who can put down the kale smoothie and “medical” marijuana and simply take notice.

Climate change is an early Christmas gift for Big Government.

It gives power-hungry politicians a politically correct excuse to control, regulate and tax the hell out of massive billion-dollar industries. It also gives Big Government, aka the “Nanny State,” a springboard to control the masses.

The reality is, if a government can regulate your carbon footprint, it will be able to control virtually every aspect of your life. From the food you eat, to the drinks you consume, it will dictate a broad range of your collective purchasing decisions.

In short, Big Government would acquire unprecedented power and control over the economy and free market.

It will mandate which cars we drive, which appliances we use, which types of homes we build — and even which kind of water we drink. Yes, H2O. In Concord, extremist “environmentalists” have already banned the sale of bottled water.

In the name of fighting climate change, government will infringe on our collective right to privacy — the right to make our own product choices without interference or penalty.

Never mind scientific reports the earth hasn’t warmed in 17 years. That inconvenient truth gets in the way of liberal fundraisers who use alarmist scare tactics to pull money out of donors’ wallets.

Organic food for thought: What if the climate change isn’t really about saving polar bears? What if it’s simply a brilliant propaganda tool used to win elections?

Here’s the deal: If you think the Nanny State is bad now, you ain’t seen nothin’ yet. The powerful cabal of environmental activists, progressives, political operatives, wealthy tycoons and special interest groups is just getting started.

As long as liberals flog their climate-change agenda and keep winning elections, government will keep banning products, disrupting the free marketplace and stripping our freedoms.

So buyer beware.
