I've talked personally to climatologists. My mother minored in meteorology. I've read the articles, I've watched the documentaries, I've seen Bill Nye. The "evidence" can point to many conclusions. Also, from personal experience, I'm not at all convinced we are causing global warming. And I'm not even convinced the earth, on average, is warming rather than cooling.
What is a fact is that people/politicians (those with power) have agendas, and they will steer beliefs about our climate/atmosphere with all their might to meet these agendas. There are many sheep that will buy into these beliefs and repeat them as if it were an original idea of their own. Don't be sheep, don't let them make you into a solder for their agenda. Be careful, be discernful. Stay beautiful.
