I try to understand people, and your despair is loud and clear here. Change is inevitable for sure, man or nature (man is nature, BTW). The sun will devour the inner planets in 4 billion years, but it is burning brighter each year, and in 1 billion years, it will boil off the oceans, coral and all. To the stars if we wish to preserve humankind.
There is a lot of complaining that nothing is being done. There should be some basic steps aside from accepting your problem to begin with, and that is to study some solutions:
#1. Propose and study solutions to match your conclusions of climate change - I don't find too much here compared with the amount of continuing studies on the climate.
And very important to get intellect to act -
#2. Who's going to pay for it, and on whose back falls the labor to implement #1?
Financial illiteracy is the big problem nobody talks about when discussing STEM deficiencies. You may need to build a skyscraper, but if you have 2 guys, 100 bucks and 1 day, you are going to be living in a lean-to, or a makeshift tent at the end of the day, no matter how much you complain or dream. I try and do my best to live minimally, because I prefer it, it makes me feel more peaceful and less distracted, and gives me plenty of time to read and think. I don't preach that all should live my way.
On a more cheerful note, I found a Tweet today about Sweet Meteor of Death, but it was in reaction to people's political apathy or neuroses over the coming U.S. elections. An apocolyptic meteor for POTUS 2016! You should buy the tee shirt and smile!
