Having been around long enough to remember the 1970's "The sky is falling" panics about global cooling, mass extinctions, agricultural failures due to frosts and freezes, etc., etc., I am a skeptic that this "global warming" excitment is anything more than the latest panic over something that is no more than a passing part of the natural cycle of climates.
That's why the scientific method is so important. When used responsibly it is essentially self-correcting over time. The human mind, however, is not. In fact it is highly prone to biased and exclusionary reasoning. To be perfectly frank there is no reasonable comparison between a tiny number of media-hyped global cooling theories that enjoyed only the briefest of attention in the 1970's and three decades of sophisticated climate change models that are respected by the vast majority of the world's experts today. Heck, even Curious George eventually gave up debating the undeniable.
"I recognise the surface of the earth is warmer and that an increase in greenhouse gases caused by humans is contributing to the problem." - George W. Bush in Copenhagen, Denmark on July 7, 2005.
In the end Bush simply claimed that it was too expensive, too complicated, and too late to actually fix the problem. He also blamed China and India for America's inability to do virtually anything of actual significance. Which is rather unfortunate, because no matter which variable you believe is
most responsible for causing global warming, the one and
only variable that humans have any control over is our greenhouse gas emissions.
That does not mean that I am unconcerned about gas, oil, and coal consumption for completely different reasons. We will at some point reach the practical limit of availability of these resources.
The thing about oil depletion is that it's only relevant in the context of cost. So long as petrol remains at current price levels there will be plenty to go around. As the price increases and technology improves more and more sources will become economically viable over time. It is my understanding that there are already
hundreds of years worth of oil reserves available for exploitation today at various price points and that more are being discovered all the time. Simply running out of oil is unlikely to be a serious problem for generations yet, but burning as much as we can get our hands on comes with a cost we may not be able to afford in other ways.
Reasonable and practica alternatives must be found, and sooner is better than later. Solar and wind are at best "botique" sources despite being the fads of the moment.
At one time every single power generation source was nothing more than a low scale prototype operation. Over time they were researched and subsidized until they became the clockwork behemoths they are today. I have no reason to believe solar and wind will not follow the exact same path as virtually every other power source as they are implemented into larger and larger installations. Even here in anti-green Texas we have several commercial scale wind installations and are moving toward commercial scale solar installations as well. The only problem so far is that our antiquated power distribution network is not setup to efficiently move this power in more than one direction.
There is no power source
less practical or
more "boutique" than nuclear fission, and yet that process still accounts for more than 20% of America's enormous electrical power market. I don't believe waste is good at any level, but if the American media is going to completely freak out over a $500 million dollar loan to a company like Solyndra then where is the outrage over the $20
billion in public loan guarantees that the US government is using to push for a 'nuclear renaissance' that the private credit market still refuses to fund on their own? Twice the US congress has tried to increase nuclear power guarantees to over $50
billion and were only thwarted by language unrelated to the nuclear subsidies. Amazingly, $50 billion worth of guarantees wouldn't even come close to what is necessary just to keep nuclear power in the 20-25% range as our current plants are carefully decommissioned, chopped into tiny pieces, and hauled to god only knows where for the next million years or so.
Where is the major work toward geothermal? If this plant has anything, it is rocks hot enough to boil water and spin turbines. This is where serious money should be spent, not giving it away to political supporters of the idiots currently in power.
Geothermal has a lot of potential but is still new to many politicians. Here in Texas it makes even more sense because we have already drilled this state into Swiss cheese while looking for oil and would not need to spend as much as other states would to get started. However, until we can get our politicians on board it will be hard to get anything approaching a commercial scale operation.
