Global Warming is More Scare than Science
by Alan Caruba (June 23, 2005)

Summary: The enormous financial power of environmental organizations, funded by leftist foundations, permits them to continue telling "global warming" lies. Meanwhile, scientists struggle to tell the true story about this hoax.

[www.CapMag.com]

On June 13, USA Today declared that “The debate’s over: Globe is Warming.

The author referenced flawed computer models in the article.

A few years ago I saw a show in which two groups debated the global warming issue. One group was comprised of NASA scientists.

The group from NASA presented first. Their position was that global warming is occuring.

The other group stated it was not.

Both sides used data from NASA computer simulations run on supercomputers. The 2nd group pointed out that the NASA model did not account for factors of water or wind.

When asked why the group from NASA stated that, even with supercomputers, the variables needed to include those factors where too numerous for our existing technology.

Now, I'm not a rocket scientists (pun intended), but I know the two primary means of cooling an engine are air flow (wind) and coolant (water) being circulated throughout the engine.

Point is, I assume if you remove from your model the two major cooling factors on the planet, it probably does look like global warming is happening.

Just like the engine would overheat if you removed the water pump, radiator and fans.

I'm not familiar with the argument you are relaying, but with all due respect, I think you've mangled it pretty badly. You have to differentiate between "closed systems" and "open systems".

Briefly, a closed system is something that does not interact with anything outside that system. An open system is free to lose material or energy without restriction.

An automobile engine is a classic open system. The radiator and wind provide a way to transfer energy (heat) from inside the system (the engine) to the environment outside.

The earth receives energy from the Sun via radiation, and in turn radiates energy to offset it. This is done partly by reflecting it off the atmosphere, partly by radiating heat from the surface of the earth back up through the atmosphere.

The theory behind the Greenhouse effect is that by putting lots and lots of carbon into the atmosphere, you are preventing the radiation of heat from the surface of the earth back up through the atmosphere.

The analogy between an engine and the earth is that an engine releases energy through convection (air passing by the radiator to the outside world or water released back into streams and rivers). The exchange from the earth is generally radiative - the earth plays heat lamp to the sun's furnace.

Beyond basic analogy, I don't understand where water-wind would change how the earth releases energy back into the universe at large.

The best coverage of the topic of global warming that I have come across is from <a href='http://www.pbs.org/wgbh/warming/' target='_blank'>PBS Frontline</a>, which does a good job of considering most of the contemporary polemics as well as having a reasoned approach to the science.

In my estimation, it is inevitable that this will be an existential problem to humanity, and the only hope of avoiding economic as well as environmental disaster lies with Nuclear Energy. Politically, IMHO, we need to abandon Kyoto and seriously fund nuclear research. If Kyoto would cost the US economy $20 Billion (very conservative estimate - I think it would likely be many times that), then put $10-15 Billion into researching fusion reactors as well as relaxing prohibitive regulatory obstacles to fission reactors. Fund ways to recover carbon from the atmosphere.

Thanks for the input. Again, I'm not a rocket scientist and I was just repeating what I saw on the debate.

When the scientists mentioned the NASA model lacked variables for water and wind, a point which the NASA team confirmed, I assumed they meant it for their cooling properties. Maybe not.

I didn't intend to be harsh or blunt. If I had to guess, they may have been talking about whether the current measurements to tell if there is "warming" today. That is a fairly controversial topic in and of itself - there is no real "global thermometer". The theory of greenhouse emissions is less controversial, although the models of what happens is controversial. I may be wrong, but I don't think many people dispute that having lots of carbon in the atmosphere is bad.

There are a number of red herrings in the debate (actually, I'd say about 80-90% of the arguments are nonsense). Among those are:
  • Forest growth is capable of balancing fossil fuel emissions
    There is only a 20 year supply of oil left (and the clock starts right now. no, right now...)
    "Renewable energy technologies" are a useful pursuit in a growing global economy

If I recall, water vapor does not act as a cooling factor in a global sense. It retains heat and compounds the "problem".

My problem with the whole issue is that you have groups of scientists trying to get a grasp on the global effect of emissions and a group of politicians ready to dismiss anything they find that doesn't suit their agenda. Global warming is far from an exact science and each modeling attempt can yield drastically different results depending on what factors you give higher priotity to.

Right. Vapor can distribute heat, which complicates measuring global climate change (i.e. to proove we're getting warmer, you have to show that you're not just warmer in one region of the world, while cooler in another - in which case there is no net change). It does operate as a "greenhouse gas" in that it can prevent the earth from radiating heat - i.e. heat reflected from the surface can be absorbed or reflected back by clouds, etc.
