There is no science that proves man has caused climate change. Consensus is not science.
If you hearken back to your days when you studied biology, you might remember that plants "breath" CO2. If we reduce Carbon emissions, then plant life will not thrive. These same alarmists cry about global hunger, yet try to regulate and destroy the very mechanism that encourages plants to grow and reproduce.
This stuff is not that hard. Logic will always win the day. This is about money, control and power. Nothing more.
