As far as climate change goes, I sometimes wonder if we are looking at the wrong culprit. It's not CO2, its heat rejection. According to a Google search I just did, US gasoline consumption in 2014 was 374 million gallons A DAY. Most of that was probably burned in internal combustion engines, located in automobiles.
Let's be generous and say all those ICEs were 35% efficient. That leaves 65% of the BTUs of all that gas rejected into the atmosphere. Every day.
That's not counting diesel or turbine fuel consumption either, which I'm sure is a significant contribution as well. And we're only talking about the U.S. here - China, Europe and Russia and many others are in on the game as well.
Does global warming exist? I can't say, I'm not a scientist. But I know when I park my fully warmed up car in my garage and close it up, the air isn't cooler 30 minutes later - it's heated the garage nicely. I'm not a tree hugger or any of that, just making an observation and a ( probably demented ) theory.
Now as far as the stock market goes, it's a very cyclical thing that takes combinations of things to move it, emotion being one of them. I've invested in the market for decades and while there's been ups and downs, my money has grown. I'm retired now and lots of my money is in dividend stocks which tend to have a limit as to how much they rumble around in good times and bad. The stock market is the only place to put your money nowadays if you want to see it grow - just buy solid stuff and don't look at that man behind the curtain....
