Human caused climate change is nonsense
You have assumed that CO2 is a dangerous substance which needs to be reduced. First mistake. CO2 is not a dangerous substance. Plants use CO2 to grow. When a plant grows, Most of its weight and bulk comes from CO2. The more CO2 that you pump into the atmosphere the faster and more vigorously plants will grow in response. Thus, CO2 is necessary and vital to create and mature plant growth which in turn gives us more food to eat. Thus, It is part of the oxygen, Water and CO2 cycle of life. It's CO2 in the lungs that tells a person to breathe. If you didn't get any CO2 into your lungs your brain wouldn't give you a signal to breathe. Properties of CO2 CO2 has similar properties to glass. When CO2 has reached it's saturation point it can no longer reflect infra red light. It's saturation point is about 80 parts per million. Thus, Any additional CO2 will have zero effect on increasing global temperatures. Global temperature. The global temperature isn't capable of being effected by humans due to the mathematical ratio differential between the size of the Earth and the total mass weight of humans and their machines. The size differential is trillions and trillions and trillions and trillions to one. Thus, Humanity represents the equivalent of about 3 grains of sand on a 100 kilometre beach. Thus, It is quite laughable that humanity thinks that they can make a difference to global temperatures.
