An all this points toward is are endless dependency of fossil fuel. Which is causing climate change plus other natural climate change factors. We humans are helping to accelerating it, With in just few decades not the slow process the mother nature has gone through over thousands of years.
So whats the cure, eleminate mankind??? eleminate cows??? not feed the people or move the food from where it is grown to where it is eaten??? eleminate fossil fuel..can we build a nuke plant in your town..for that matter can we build a wind farm in you town.
In these "few decades", the average temperature of the planet has risen 0.7 degrees. How much do you think it went up at the end of the last ice age. Not many cars around to blame then.
There are very specific things that we are doing wrong to our environment.....The "sky is falling global warming" crowd is an agenda to sell books, put viewers in front of CNN and make reputations for competing crews of scientists.
Lets do something about the things that we can.
As to cars.....1 running lawnmower emits as much polution as 30 properly smog equipped cars per hour.!
Rats, not the OP which was relatively tongue in cheek has gotten all cluttered up with dualing soapboxes. Sorry
