Questions: Earth's temperatures are the result of a number of variables, of which humans are the shortest lived (~2,000,000 years, 300+/- industrialized) in the past 4.6 Billion years. Even going back through the Cambrian (the last 600,000,000 years), temperatures have risen and declined through natural processes without human intervention.
Human effects on surface temperatures, through industry or war, beyond localized effects, have not been generally proven to exist, or be significant in scope or duration in the event they do.
What if the Earth is simply peaking in a natural warming cycle, and starting a cooling cycle as this is deployed, with the objective of lowering global temperatures and the concept proves effective?
Is there any way to mitigate or reverse (nullify) the effects of such intervention to prevent an Ice Age?
Have the effects of global temperature increases been thoroughly assessed on a global basis, or are the postulated effects only evaluated on a basis of maintaining the status quo, especially with regard to property values?
While some on Earth will possibly suffer from the effects of natural climate changes, others may well benefit. Certainly, the most populated areas today are those found to be most desirable by a majority of the population, would those people be the ones to decide what happens to the rest of the planet?
Would we leave the future of our habitation here dependent on the unproven assumptions and computer models which have failed to provide accurate projections and those who have sought to cause panic in the general population to cause demand for action when inaction might be the best course?
Humanity has traditionally moved when it found where it was living to be inhospitable, yet despite that, every climate regime present has a human population. We adapt, relocate, or otherwise devise means by which to survive natural processes. We do not seek to intervene in processes which have continued for hundreds of millions of years, any more than we try to plug volcanoes or stop continental drift (plate tectonics).
As history indicates, humans do best when the climate is warmer, not when it is colder. Intentionally propagating colder temperatures using an unproven method with unknown results which cannot be reversed would be inadvisable; a step in the wrong direction.
Get a bloody parasol, you wankers! His predictions are from a novel. Fiction. (If you want to 'save the planet' by blowing sand from the Middle East into the Stratosphere with nukes, that remains a possibility)
