Ignorance is a problem in itself but it is compounds itself because people, especially leaders, will lie and deceive to hide that ignorance... They don’t even know that the claim that CO2, especially from human sources is causing climate change, is completely without theoretical basis.
I know that no world leader read this because if they had, they wouldn’t daily display their ignorance. We are led by ignorant, uninformed, people... these ignorant leaders imposed their ignorance on other leaders.
We are led by fools and incompetents who deliberately choose to stay stupid by not looking at even the simplest of information. Now with the Internet it is easily available so the only excuse left is personal incompetence.
