So, I am not extremely educated on scientific matters. I didn't get a science degree in college. I studied philosophy.
As such, I don't feel qualified to personally understand what the causes of climate change are. I do however have a decent amount of friends who are engineers, and I have seen the types of alternative energies there are available.
My opinion is; regardless of whether or not the use of fossil fuel and coal are causing the climate problems we see today; we should be using cleaner, safer, cheaper energy, even if our irresponsible use of resources has nothing to do with our environment
