Better, more accessible sources on the supposed "climate disaster"

I decided I'd better do some further research on the quote about Greenland I included in my post concerning the bad science of climate change.

I'm glad I did.

I came across the World Climate Report blog, what appears to be a much more accessible source of scientifically valid responses to the fear-mongers than is Steve McIntyre's excellent, but rather dense, Climate Audit site.

And so I found Greenland's Secret, an article from March 2004, where we read,
The recent hype in Nature notwithstanding, Greenland has been cooling for the better part of two generations.

It’s hot news: Temperatures in Greenland have been rising like a rocket during the past 10 years or so—returning to the temperatures that characterized the 1930s, ’40s, and ’50s.

Yet that bit of history—that temperatures were as warm or warmer in Greenland 50 years ago—appears lost on the global warming crowd. Instead, they have increasingly pointed a finger at the changing conditions there during the past decade as a clear sign of anthropogenic global warming.

An article in the March 11, 2004, issue of Nature magazine even goes so far as to suggest that Greenland may be on a path of warming and ice loss from which it can never recover. Apparently, Nature writer Quinn Schiermeier is ignorant of the fact that 70 years ago, a similar temperature rise in Greenland was followed by six decades of cooling—it seems as if it recovered from that warming just fine!

Go down to the lower right of any page in World Climate Report, and you will find a list of other blogs and websites and a number of intriguing books and DVDs. Among the latter, I am particularly taken with The Satanic Gases: Clearing the Air about Global Warming by Patrick J. Michaels and Robert C. Balling, Jr. "Citing the pioneering work of historian of science Thomas Kuhn and economist James Buchanan, Michaels and Balling demonstrate that it was inevitable that global warming would be distorted by the political sphere and that most scientists would either stand mute or actually assist in that process. But, the authors argue, such distortions in science are always temporary, and inevitably the scientific community will concede that earlier forecasts dramatically exaggerated the threat of global warming," says the blurb.

I only hope so. And that this final message comes some time before the socialistas place us small people under the weight of draconian laws that destroy our freedoms and cause us to suffer unnecessary want.

--Somehow I think I will be returning to this subject again.

It's too scary that both leading presidential candidates seem to have jumped on the global climate disaster bandwagon. I mean, McCain has been on that bandwagon since 2004, it appears. And Obama-come-lately, of course, isn't going to let a Republican out-Green him! Why, don't you know? "[R]eplacing the oil we use with . . . home-grown biofuels . . . will finally slow the warming of the planet." (Original sentence: "But building cars that use less oil is only one side of the equation. The other involves replacing the oil we use with the home-grown biofuels that will finally slow the warming of the planet." --Remarks of Senator Barack Obama, "The Coming Storm: Energy Independence and the Safety of Our Planet," Chicago, IL, Monday, April 3rd, 2006.)

Doesn't it comfort you to know these guys are ready to "work for you"? (It doesn't me!)

I think I'd better quit now before my blood pressure rises too high!

Becoming angrier about the climate fear-mongers

Like too many subjects I deal with, it seems a lot of our culture-shapers (i.e., journalists) simply spout the "received wisdom" rather than truly seeking to discover what "the other side" has to say.

And so it was this morning that I read the following in an e-newsletter I get each day (but read maybe once every couple of months on average):

COAL KEEPS THE LIGHTS ON IN AMERICA – CAN WE MAKE IT CLEANER?
by Greg Guenthner

. . . coal would be sitting pretty. But the black rock is under attack from governments, scientists and ordinary citizens throughout the world. And with no end in sight, our main source of electricity is in serious jeopardy.

The prolific use of coal as a power generating fuel is causing massive damage to the planet in the form of carbon dioxide emissions. This is not a political statement – it’s been proven over and over again by scientists and accepted by governments and the United Nations.

Today, oil we burn in our vehicles and use for power generation is the number one source of CO2 emissions. . . .

I was tempted to respond to both egregious errors in this brief section of Guenthner's article (about the supposed "massive damage" caused by carbon dioxide emissions and the supposed truth that human beings and our energy requirements are, somehow, "the number one source of CO2 emissions"). But I held my tongue. I only wrote about the first matter.
Friends:

I wish Greg Guenthner might have done--or might yet do--some better research about the supposed "proof" for "massive damage to the planet in the form of carbon dioxide emissions" and concerning the supposed "massive damage" itself.

I invite you--and Mr. Guenthner--to read What is the "Hockey Stick" Debate About?, just about anything on the Climate Audit blog by Steve McIntyre, and “the take-home messages” at the end of The Real ‘Inconvenient Truth.’

I would have hoped Agora Publishing and The Daily Reckoning would be more attentive to exposing fraud rather than perpetrating it!

Sincerely,

John Holzmann

“Who Killed the Electric Car?”

As I mentioned in Denver to New Zealand--A Midwinter/Midsummer Vacation, I watched "Who Killed the Electric Car?" while flying to New Zealand. And as I have indicated in I Want One, I am very interested in at least one electric car . . . and, possibly, others as well. (I have been interested in alternative fuel cars ever since I was a boy when I read that the Stanley Steamer was the fastest car of its era; that it could go from forward to reverse without shifting gears, and its major flaw--besides occasionally exploding (a charge that the Wikipedia "Stanley Steamer" article denies)--was, as I recall, that a person might push a bit too hard on the brake and find him- or herself suddenly thrown from the vehicle when it went from high speed acceleration forward to high speed acceleration backward in an instant.)

But back to "Who Killed the Electric Car?"

The film is an ode, more or less, to the EV-1, a General Motors vehicle I had never heard of before, and an investigation of why the vehicle was developed in the first place, why “no one“ ever heard of it, and why there aren't any more on the street today.

A very powerful piece of propaganda (if that's what you want to call it). Or an effective piece of investigative reporting. It impacted me deeply. In fact, it has caused me to question some of my political ideas and/or commitments.

Example: The film has someone--Ralph Nader, I believe--say that virtually "all" the major improvements in automotive safety and efficiency in the last 50 years have come about as a result of federal regulations. The car companies themselves, he said, didn't bring us seat belts, 20 mpg or better fuel efficiency, low-emission engines, etc. Oh, they developed the technology, all right. But they didn't make these a regular part of the cars that all of us drive until the federal government mandated the improvements.

Now, that gets me thinking. From a marketing perspective. Of the three technologies I have mentioned--seat belts, fuel efficiency, and low-emission engines--which could have been achieved without federal mandates?

Seat belts. Couldn't they have become standard equipment without mandates? It would have required some significant education to get people, first, to purchase them in significant enough quantity to lower their costs.

Or would it?

I wonder if the Detroit manufacturers of the late 50s and 60s would have been "able" to put in seat belts if the Japanese manufacturers of the 70s and 80s had been present to spur them on? Aren't there a lot of manufacturers today who build their cars with additional steel bars and plates and additional airbags . . . and who tout their resultant superior safety records?

Apparently, they find these safety features pay for themselves through added sales.

Or do they? Or, should I say, would they if they were seeking to appeal to the mass market? Is it the case that, yes, they can make money as long as they are selling to the high-end car buyers, but no, they would lose money if they added all these additional features and tried to sell them to the lower end of the market--the people who can afford the $10,000-25,000 new vehicles?

Fuel efficiency and emissions are very similar, to my way of understanding.

A year or two ago, I thought I would like to buy a Prius for Sarita. The Prius would be our second car, a commuter car. (What hybrids are supposed to be best suited for: efficient for stop-and-go, around-town driving.)

Except, as I recall, even calculating an average of $3.50 a gallon for gas, it would take something like 10 years or more, at the rate Sarita drives, to make up the $9,000 price differential (as I recall) between the Prius and the Corolla. . . . So we bought the Corolla.

So it is, I'm afraid, with most automobile technologies. Unless and until they become mainstream and/or mandated, so that all new cars use the technology, the price differential is too great for most consumers. . . .

*****

Another example of how the film caused me to question my previous ways of thinking:

Overall, I have been only moderately critical of George W. Bush from early in his presidency for a number of reasons.

Some things have driven me absolutely nuts:
  • He (and the Republicans in general) have seemed wimpy, lacking in backbone or conviction.
  • I "can't believe" what a fiscally irresponsible "leader" he has proven to be, refusing to veto any spending increases and, in fact, adding large sums of money to plans already approved by the supposedly "liberal" Democrats.

    (In the '80s, it was popular to speak of the "tax-and-spend" liberal Democrats. I had come to the point where I began speaking of the "borrow-and-spend" [supposedly conservative] Republicans who put our nation in horrendous debt.)
I have questioned his wisdom in venturing into what appear to be foreign entanglements. (Although in today's world, as at least one friend has noted, people around the world are so interconnected economically, let along socially and politically: it is hard to argue that what happens in a place like Iraq is truly of no concern "back home.")

But I am no knee-jerk Bush-basher, either.

However, in "Who Killed the Electric Car?" I was stunned by revelations about Bush and about Reagan and their policies concerning oil . . . and energy. Absolutely stunned. (Assuming, of course, that the film speaks the truth.)

According to the film, Jimmy Carter, in 1977, I believe, announced a policy that, he said, would keep the United States from every importing more oil than it had in 1976. I believe the figure he mentioned was 8.5 million barrels of oil imported per day. Something like that.

I vaguely remember some of the policies and regulations put into place during Carter's tenure. Vaguely.

Some of the policies had to do with automotive fuel efficiency--CAFÉ, as it was called--Corporate Average Fuel Economy, "the sales weighted average fuel economy, expressed in miles per gallon (mpg), of a manufacturer’s fleet of passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 lbs. or less, manufactured for sale in the United States, for any given model year."

And between 1976 or '77, when the regulations went into effect, and early 1980-something, the average car sold in the United States went from something like 14 mpg to almost twice that.

Whatever. Automobile fuel efficiency skyrocketed.

When Reagan came into office, however, many of Carter's energy policies were reversed.

Tax credits that Carter had helped enact in order to encourage greater investment in solar energy--solar roof panels to heat buildings and water, for example--were reversed.

Carter had placed solar panels on the White House roof; Reagan had them removed almost the moment he moved into the White House.

The film offered no reasons why Reagan had done such a thing. I imagine it was largely symbolic: Carter's era and the years immediately preceding him had been full of austerity and economic hardship. Reagan probably wanted to signal--what I recall was a chief campaign theme--a new day in America.

But why waste the benefits we, the people of the United States, had already paid for? Why waste the energy that the Sun provides and that the White House had been equipped to capture?

The film's revelations of these things bothered me.

I have been very interested in fuel efficient buildings and cars, not just intellectually, but practically . . . if I could possibly justify the purchase of such things in economic terms.

I mentioned the Prius.

I had us pay an outside consultant who specializes in these things evaluate the feasibility of us using geothermal energy as a conservational measure for the building we constructed for Sonlight back in 1999. Sadly, under even the most positive analysis, as I recall, the energy savings wouldn't have paid for the additional costs in 20 years. --A 20-year payback is equivalent to a 3.53% compound return on investment.

And some analyses suggested the payback could take up to 50 years. . . .

So that measure made no sense to me and I refused to make the investment.

But Reagan destroyed an energy conservation measure that had already been paid for. Why? That made even less sense, it seemed to me.

The film emphasized these shifts at the federal level. And the revelations bothered me.

But what really burned me up was the revelation that, under George W., at the very time the federal government was removing $4,000 tax credits for fuel-efficient electric cars like the EV-1 (and others), they added tax deductions for 6,000-pound fuel-guzzlers like the Hummer: up to $100,000 per vehicle!

A $100,000 deduction for purchasing a gas guzzler, and the elimination of the very modest $4,000 benefit for electric cars?

I was shocked and angered to hear such a thing!

And Bush claims to be concerned about the environment and fuel conservation?
