Well, Pete, here's the basics. Over the last 150 years or so, carbon dioxide emissions/deforestation have increased the atmospheric carbon dioxide level by around 20%. In the last few decades, global warming has increased in almost perfect sync with increasing carbon dioxide. The rate of warming in the last few decades is unprecedented since the end of the last ice age. The situation is no longer arguable, in spite of the best efforts of big oil and the US. Catastrophically, emissions now are greater than ever. Fanny around arguing about it all you like. The immoral position is to say that we're not sure and that we are therefore justified in doing nothing. There's a lot of it around. You will find next to no scientists taking that view. Of course, Pete, we know you don't trust scientists. Good job you're in charge of nothing.
