Young Greta Thunberg has correctly stated the case that the UN Climate Action Summit was a failure, but then, it was doomed to fail anyway. The members of the Summit have not yet even determined what factors actually do affect the climate, and the degree to which those factors, even if once identified, could be changed by any action, individually or collectively, by mere human beings.
The entire ecosystem of the earth is terribly hard to change in one direction or another by any means yet devised by mankind. Just the sheer volume of the various factors of the biosphere (ocean and other surface waters, land surface, and atmosphere) prevent the actions of humanity from changing more than only a very small point in the whole balance of things, and the homeostatic nature of the interacting systems probably negates even that small point source altogether.
Carbon, in and of itself, is neither good or bad. In fact, it makes up a major portion of ALL living things, and one of its forms as carbon dioxide, is as essential to life as the element oxygen itself. Free oxygen in the atmosphere could not exist without the presence of green growing plants continuously replenishing that highly reactive element by reducing carbon dioxide.
Carbon dioxide is not a pollutant. It is the most essential of all plant foods.
A miracle that escapes the perception of many.
Thanks.
The climate has always changed and always will, controlled by forces man only partially understands and cannot control, and which has been doing so for millions of years.
