Denying Climate Change Requires Willful Ignorance

3
If Admiral Titley doesn't lose deniers when he addresses evolution, then their eyes will glass over when the discussion turns to data and real science for comprehension. Dismissing measureable data and employing the argument that trace substances are insignificant require the suppression of intelligence. It's not stupidity; it's fear.

The sun's radiation, measured by NASA for a half century now, has remained constant to within about +/- 0.3%. We also know that the greenhouse gasses reradiate long wave radiation. Again, that reradiation can be measured by NASA. The amount of heat leaving the atmosphere at those wavelengths has been decreasing. That's the basics.

Ocean Water Acidification; Outpacing 100,000 Years in 150

Ocean water acidification is the third and possibly the most immediate threat to national security. Admiral Titley calls it the silent cousin of global warming. Simply put, a whole lot of carbon dioxide released into the atmosphere ends up in the ocean where creatures have adapted to different conditions.

Since the beginning of the Industrial Revolution, the pH of the oceans has dropped from 8.0 to 7.9. What's the big deal?

"We have changed the acidification of the ocean more in the past 150 years than it changed, in best we can tell, in about 100,000 years. So the critters, again a technical term, have gone and evolved to living in a pH of 8. All of a sudden, in just like "bang," in terms of evolution, we have shifted the environment." - Admiral Titley

If that turns out bad (and there is evidence it already is) there will be a billion people who currently rely on the oceans as a source of protein stressing agricultural resources. And those agricultural resources are no longer as predictable because of changes in rain patterns and water resources. Competition for natural resources at the national survival level drives nations to kinetic conflict. So there will be two reasons to respond: famine and war. Both demand scarce assets. Our nation's current role in the world demands our involvement. Or, we forfeit that role and the moral advantage it potentially provides. And so begins a downward spiral that ends up with our motivation in all commerce as base as survival interests. And that is not the America we know and love; the values we hold dear.

Threat 1: Opening of the Arctic Ocean
Yesterday: Rising sea levels
Today: Ocean water acidification
Tomorrow: A little more ammunition against skeptics (but they can't handle the truth)

Rising Sea Levels And National Security

In this second of the three aspects of climate change that threaten national security, Admiral Titley discusses rising sea levels. The pace of change is gradual. The magnitude of change is small. And that allows deniers respite from reality. But the environmental effects, though local, will be catastrophic.

Glaciology combines the science of numerous disciplines. Deniers want to use simple observations of surface ice to support their conclusions. Unfortunately, it is not so simple. Ocean water is warming and with that the relationships of the glaciers to the earth on which they were grounded. Many are now afloat. We are not so certain what this means. What we know is that there is data to support the projection of a one meter sea level rise by 2100; and that is conservative.
