I have an engineering degree, so I know my share of physics. I can smell bullshit about mechanics and engineering no doubt. I can gather the evidence, I know where to find it, how to judge the quality and conduct experiments to test my theories. But my knowledge is limited to my domain.
My knowledge of biology or climate science is limited. I'm not an expert nor do I try to be an expert. I don't have the time or the skill set together better evidence comb through the different theories and the mountains of data to come to my own conclusions. I must trust the scientists of their fields because they trust me with my knowledge. It's impossible to be an expert in multiple domains in today's world.
It's unreasonable to ask to draw conclusions of highly complex systems that most people will need, at minimum, a domain specific university degree to understand.
Sure! But that's not a silver bullet.
Decarbonization is a multi-prong solution and switching everything over to public transportation would take decades. It takes time to create the infrastructure and generations to change minds. Investing in public transportation, bike infrastructure and electrifying our cars are all necessary for our goal to lower green house gasses.
Perfect is the enemy of good
