I grew up in the 60's & 70's & I remember all the experts & magazines telling us by the year 2000 The planet would "cool" off due to the "greenhouse" effect created by man made pollution to the point where we would have less area to grow food & shorter seasons to grow food to feed the incredible overpopulated planet & than we arrived at 2000 & ooops that didn't happen. So they devised another method stealing our money, "global warming", well that wasn't working either ,so it's now "climate change" these greedy bastards have come up with. The question I would ask is this. Who says that the temperature today is the base temperature for the planet? Maybe the earth needs to warm up 5, 10, or even 15 degrees to reach the optimum standard for habitability for all. I don't know , they don't know. One other question why would the two biggest polluters (India & China ) be exempt for 5(?) years & the USA where we have done a major turn around towards a cleaner enviorement wouldn't be exempt?
