  • Don't confuse changes in the weather with global climate change. Localized phenomenon, even trends over decades in one area, are not indicative of the problem we face. Those who challenge the claim of a climate problem use data over millennium to accurately observe that cyclic extremes in global climate are natural.

    What is crucial to understand in this debate, is the realization that the composition of the atmosphere and ocean is trending in unique ways from that seen at any other time in history. Ice cores from miles deep in the Arctic/Antarctic show the composition of the atmosphere through millions of years of Earth's history. Never before has the climate been influenced by the current trends in the chemical composition of our biosphere. That is the risk to us. Key variables in the experiment of life are being grossly altered over a very short period of time. The real fear is that perturbations of these magnitudes will drive climate in non-linear directions.

    Yes, the weather changes frequently. Yes, global climates have changed throughout time. Yes, to date, stasis has always maintained a climate balance that avoids extremes which would be non-viable to most life forms. However, the dynamic today, when modeled in ever more accurate simulations, is showing a non-linear dynamic. The balance of climactic forces is now seen as being threatened and a new balance around new and unknown attractors may not sustain existing life forms.

    My fear is NOT for our globe. Gaia will survive. However, mammalian life, including Humans, may not. Between today and Human extinction is a new Epoch, which may begin in the span of only a few generations and would consist of a rapidly increasing difficulty in maintaining the lifestyle we now enjoy. The changes may be extreme, sudden, and life threatening to billions of Humans. Would you survive a hurricane hitting Manhattan? How about the roaming hoards of hungry gun toting homeless that would result?

  • There is no real need for or room for more over-educated semantics about the weather changing the way it has. It seems confusing, as well. I am optimistic that humanity will solve the global warming and pollution crises in the same way a child is born into this world, "Sink or Swim!"
