Few real scientists are at work it seems, no matter how many letters these posers write behind their names. They have given up the pursuit of real science and have instead become little more than numerologists, looking to foretell the future by finding coincidence in numbers, just as numerologists find intricate details through mathematics in the religious texts.
The unfathomable energy in, and the sheer scale of the planet and atmosphere are beyond the ability of man to impact significantly. For example, the last eruption of the Yellowstone Caldera, thousands of years ago, is estimated to equal the equivalent explosive force of 2,000,000 megatons of TNT. This single geological event can be compared to the entire inventory of deployed nuclear weapons in the world, which have a total explosive force of just 12,000 megatons of TNT.

If mankind decided tomorrow that life on Earth must be destroyed (even just human life), he would fail pathetically and would accomplish little more than making a big mess. The mess he made would then be cleaned up by Mother Nature in the blink of a generation or two.
The mere elevation of knowledge in exchange for the ever mischievous antics of the Greek gods has not bestowed god-like powers on man. It is unfortunate that the most learned amongst us, have taken to delusional fantasies of grandeur, and would have all of us fear their predictions of doom just as man once feared the scorn of the gods.
