It used to be the new ice age was coming, then global warming. Now it's climate change and in particular, HICC which stands for human-induced climate change.
It is all baloney. I'm almost 61 and the same spiel is being pushed. Carbon taxes are the answer is what we hear lately. Yep, tax something you cannot see, the ultimate in taxes.
Live your life. Sure, don't try to pollute if you can, but forget about these alarmists. They are in it for one reason and that is $ ¥ £ €.
