one small proposal for gettting from here to there

Our earth is undergoing measurable global climate warming that has a significant anthropogenic component, with the primary anthropogenic contribution to warming coming from the steady increase in CO2 emissions from the use of fossil fuels such as oil and coal. Moreover, warming that has already occurred over the past century and warming that is certain to occur in the next century, have had and will have recognizable negative impacts on the health of human beings and human societies. Those impacts include, but are not limited to, rises in sea level and loss of shoreline, changes in plant and animal populations (declines, increases, shifts in range) including changes in disease vectors (such as West Nile Virus and Malaria carrying mosquitoes), increasing drought with its impact on food crops and human water supplies, and increasing extreme precipitation events with concomitant flooding.

Among the scientific community there is debate and need for continuing research on how much warming and how fast future warming will occur, and the regional patterning of impacts, but there is general consensus on the basic facts of warming and its causes and its consequences. Recent polling of the general population in the United States shows that about three quarters of the American population accept the scientific consensus on the reality of global warming and the anthropogenic causes of that warming. However, there is a decided lack of consensus both within the scientific community and the general population on exactly what should be done to address the problems posed now and in the future by global warming.

Just because people agree that a problem exists and that something should be done, has never meant that they will agree on what to do about that problem. This has always been true. There are lots of good sociological and psychological reasons for this lack of agreement. From a psychological perspective immediate, present threats to one's livelihood and material well-being are more salient and real than predicted future threats no matter how real we consider those future threats to be. A parent will always be more concerned about the present day need to keep a roof over their children's heads and food on the table today, than they will be about the availability of housing and food for those children in 20 years.

From a sociological perspective we have organized our economy around the need to maintain very short term current profitability to retain investors, rather than around long term future. The structures, rules and practices of business decision-making and investor decision-making, make it difficult for either business managers or investors to forgo current profits in exchange for long term sustainability.

For a utility company currently generating most of its electricity from coal fired plants shifting to solar or wind generation has many economic drawbacks. If a utility simply purchases "green" power from another electricity producer who is already invested in wind, solar or hydro-power, the primary profit from power production goes to the actual producer not the utility company purchasing the power. To make any profit, they have to raise the cost of that power to the customer, making it more expensive than the coal generated power, and thus less attractive to consumers of electricity. Such a move also introduces greater inefficiencies -- the further electricity is transmitted the greater the loss, so purchases power from a distant provider means that you get less power for your buck as well.

On the other hand, if a utility company decides to themselves begin producing electricity from wind, solar or hydro sources, there is the huge upfront capital investment that must be made. While this may have great long term profit potential (once constructed one never has to pay for sunlight or wind unlike coal), it has tremendous short term costs that affect profitability and investor satisfaction. If a utility attempts to pay for this by raising utility rates up front, there is substantial customer dissatisfaction, and in states (like Kentucky) with strong political incentives to protect coal, little political interest for public utility commissions to support such rate increases. Additionally, the construction of a centralized solar or wind generation plant requires huge acreage, that may not be readily available to a utility company near its customer base.

Finally, another reason that utility companies become nervous about discussions, is that the idea mode of generating electricity from solar energy is a pattern of dispersed, household level or building level generation, where solar panels sufficient to the needs of a particular housing unit or office building are placed on the building itself. This eliminates two problems: first, all the extra land that would be needed for centralized solar generation, and second, the problem of electricity losses due to transmission over distance. However, since currently housing unit and office building solar electricity generation is financed and operated by individual families or businesses it represents a loss of revenue for the utility company, and certainly not something they really want to encourage.

Moreover, from the point of view of the individual, family or business, the cost of constructing small localized solar (and wind) generation is quite large (at least $20,000), and far beyond the reach of the median household. While such household level solar (and wind) electricity generation does pay for itself over twenty to twenty-five years (the vast majority of the costs are in the initial hardware and installation and after that the electricity itself is essentially free), the upfront costs are prohibitive for all but the most affluent and most environmentally committed.

Now, finally to my proposal. I acknowledge up-front, as a person who is uncomfortable with the power of utility companies now, this is not my ideal solution, but it is a means of decreasing the input of CO2 into the atmosphere, to ameliorate future extent of global warming and its impact, while dealing with many of the problems outlined above. My proposal is that electric utility companies currently heavily invested in their own coal-fired generation consider adopting the model used by Bell Telephone in the 1950's. In exchange for a modest installation fee (say a few hundred dollars that could be prorated over a period of time) well within the budgets of middle and working class families with "green values," the utility company would deliver and install solar panels on the consumers home -- but, and here's what I think is a new idea (at least as applied to electricity generation) the utility company would retain ownership of those panels in perpetuity, and charge the consumer a monthly fee for the electricity consumed from those panels.

Here's the details -- the one's that I think would make this idea appealing to both the consumer and to the utility company. The individual solar installations would 1) be large enough to provide for ordinary, peak daylight hours electricity use and 2) would be tied into the grid allowing for both inflow and outflow. The utility company would benefit, because all excess electricity generated would flow into the grid for use by other customers (and unlike the situation where a household customer owns the solar installation, the utility company would own that excess flow outright and not be paying the customer with the installation for it). With each household or business that added solar generation, the electricity generating capacity of the entire grid would be expanded. The capitalization costs would be spread out over time -- no huge up-front investment in generation capacity years before any new power can be generated. Moreover, following current phone company and cable company practices, the utility company could charge a very small (a few dollars) monthly maintenance fee to consumers, to cover costs of periodic maintenance and repair.

The consumer would benefit in two ways: they would have the assurance that in the absence of sunlight they would still have electricity, and conversely, during widespread power outages due to downed transmission lines they would also still have their locally generated power. Indeed, if several households in a neighborhood had contracted with the utility for solar panels, the entire neighborhood circuit might be protected from electricity loss during a widespread outage.

In the beginning only middle income and upper income families that are highly committed to environmental, "green" values would participate. I know I would. I would be very willing to pay a reasonable premium in installation costs just to be assured that while I was sitting at my computer typing away I was using electricity generated by solar power rather than by coal obtained by scalping the mountains around me. Overtime, as people begin to notice, that one of their neighbors still has electricity after a storm has knocked out everyone else, the appeal of solar panels might spread. If the utility made the cost of electricity generated in situ from the solar panels marginally less expensive (say 1/2 cent per KWH) compared to electricity pulled from the grid, this would increase the appeal of participation.

From the utility company's perspective, they are able to gradually expand their generating capacity, using "green" sources, with small, periodic expenditures of capital that can be partially charged to the customer (installation fees), and also recouped by feeding all excess electricity generated into the grid. Customers without the panels who depended solely on the grid would pay the standard rate for their electricity. By dispersing solar generation through out the households served by a utility, there would be a substantial increase in efficiency, as electricity would be consumed closer to where it was generated, reducing the losses to long distance transmission. Most of all this idea allows utility companies to make the transition to renewable electricity generation gradual and incremental, and thus less painful and more acceptable.

So there is my idea -- somebody tell me what's wrong with it!

weather is not climate, but....

The Weather Channel's website has a number of nifty new features. One of which provides you with lots of information about how your current month (and previous month) stack up against historical weather patterns. I've captured the screen shots for my zip code 41825, for June 2010 and July 2010.
Notice that for both June and July the "highest temperature recorded so far" is higher than the historical record for that month -- so we broke the all time temperature records for both June and July in Eastern Kentucky. Notice also that the total rain fall amounts for both June and July are well below the average. June's precitipation total was 1.05" below the average. Of course July isn't over yet, but let's hope we don't get 3.65" of rain in one week. While the July total rain is more than three and a half inches below normal, eastern Kentucky did get one whale of a gully-washer, to the great dismay and anguish of hundreds of folks in Pike county.



While it is important to remember that weather is not the same as climate, and unusually hot days occur periodically, as do droughts and floods, overall warming of the climate as is currently occurring on planet earth, does give rise to more frequent extreme heat, more common droughts, and paradoxically more frequent intense rain events like that seen in Pike County this month.

Where are the global warming deniers?

The first thing to remember is, as any competent climate scientist will tell you, weather and climate are NOT the same thing. A snow storm or a heat wave are weather. Climate is a decades long pattern made up of millions of weather events. Climate has predictable patterns, that can be modeled by computer simulations with some accuracy over decades. Weather is far more variable, and accurately predictable only several days at a time.

There is, of course, a connection between climate and weather. Climate is the long term accretion of weather events. More rainy days, with more inches of rain create wetter climates. And wetter climates create more rainy days with more inches of rain. However, even in the rain forest (climate) it is dry sometimes (weather), and even in the desert (climate) it rains sometimes (weather).

During the midst of the heavy snow storms, the deniers of the reality of global warming, happily confusing weather and climate, were loudly crying "where are the global warming supporters?" "Where is Al Gore?" Ignoring (of course) that models of global warming actually predict an increase in extreme precipitation events including extreme snow storms. But now the worm or at least the weather has turned. See the CNN article: Blistering heat expected in Northeast - CNN.com and a heat waves of historic proportions are gripping the U.S. this summer.

Some very hot summer days are not proof of global warming any more than some very snowy winter days are disproof. But as the climate warms, the frequency of both very hot summer days and very heavy precipitation events (winter and summer) tend to increase. The likelihood of each new summer producing new records for heat increases as climate warms.

So my question is, where are you, global warming deniers? How do you account for this? Do you only recognize the difference between climate and weather when it is convenient for you to do so?

ice watch

Since the summer of 2007, when Arctic ice extent hit an all time measured low, I have developed an ice watch fascination that generally sets in when the summer heat does in June.

The National Snow and Ice Data Center Sea Ice Index, provides a daily snapshot of the extent of ice in the Arctic Ocean. Both in map form and in a graph. The gray line is the average ice extent from 1979 to 2000, the green dotted line was the ice extent in 2007, the lowest ever measured. Right now, in June 2010 (blue line), the extent of Arctic ice is well below that of the recorded minimum from 2007 -- less ice, more open water, less reflected sunlight, more absorbed heat. This does not automatically mean that we will set a new record in 2010 for the smallest ice extent, because Arctic winds and storms can retard ice melting (and increase it); but a new record low ice extent does seem to be possible this year.

Obama blames Gulf oil disaster on breakdown at BP | Reuters

Below is one of today's headlines from Reuters, and a link to the article. Unfortunately, the President is 100 percent wrong. What happened at BP was not any type of "breakdown", but an example the way capitalism works without genuine government regulation and oversight. This is not an example of "bad people" but of a a flawed system.

Businesses in a pure "ideal" capitalist economy are beholden to their owners only and to required to produce profit for their owners. Period. Businesses are not beholden to the public, to their customers (except to the extent that they need customers to make a profit for their owners), and most especially businesses are not beholden to "the environment" or to the human species. The only thing that can change this is "interference" by government, in the form of laws and regulations, regular inspections and oversight, and fines, penalties, and in extreme cases shutting down operations when laws and regulations are not followed.

If our government does not provide this type of "interference" there is no reason on earth for a manager or executive in any business to spend money for safety measures, tests and retest, safety equipment, etc. The logic of a capitalist business is to cut costs wherever costs can be cut, to produce the greatest profit possible.

If you don't like all this snow, join the fight against climate change!

In 2003, seven years ago, the Union of Concern Scientist published the following article: "Early Warning Signs of Global Warming: Downpours, Heavy Snowfalls, and Flooding." This article states:

"Climate models predict an increase in average precipitation in winter at high latitudes due to poleward transport of evaporated moisture from lower latitudes. There is also an increase in the expected frequency and areal extent of intense precipitation over the continents."

An "increase in average precipitation in winter" means more snow!

Look at all the problems created by the snow storms in the U.S. this winter. Transportation systems disrupted. Power systems disrupted with millions of people losing electricity. Lost revenue to retailers and other businesses. Schools closed, government services disrupted. This is exactly why climate scientists have been warning about global climate change. When climate scientists say that not fighting climate change is going to cost us more in the long run than making changes to our economy, energy and economy now, this extremely snowy winter is part of what they are talking about. Among the other things they are talking about it is more frequent, more drastic alternating periods of drought and heavy rains in the other seasons.

People who want our government and economy to take steps to reduce the extremes of climate change (stopping it altogether is not possible), want to prevent even more extreme disruptions of society than we are currently dealing with this winter.

global warming models predict extreme snow events

The piles of snow blanketing the mid-Atlantic states have inspired global warming deniers in politics and the media to gleefully declare the demise of global warming...and a number of great comic responses, like this one by Jon Stewart:

The Daily Show With Jon Stewart	Mon - Thurs 11p / 10c
Unusually Large Snowstorm
www.thedailyshow.com
Daily Show Full Episodes Political Humor Health Care Crisis

Comedy aside, folks, heavy -- even apocalyptic snow falls -- are predicted by global warming theories. This is not a case (as suggested by folks like Glen Beck) of proponents of global warming seizing on every passing weather condition as it occurs and declaring it a result of global warming. The likelihood of increased extreme snow fall events arising from global warming have been predicted well in advance of this years snowmaggedeon, as the following excerpt from an article in a referred scientific journal supports:

“To assess possible future snowstorm conditions, the relationships of the storm frequencies to seasonal temperature and precipitation conditions, both estimated to undergo future changes, were defined for 1901–2000 using data from 1222 stations across the United States. Results for the November–December period showed that most of the United States had experienced 61%–80% of the storms in warmer-than-normal years. Assessment of the January–February temperature conditions again showed that most of the United States had 71%–80% of their snowstorms in warmer-than-normal years. In the March–April season 61%–80% of all snowstorms in the central and southern United States had occurred in warmer-than-normal years. The relationship of storm incidence to precipitation in all three
2-month periods of the cold season showed that 61%–85% of all storms occurred in wetter-than-normal years. Thus, these comparative results reveal that a future with wetter and warmer winters, which is one outcome expected (National Assessment Synthesis Team 2001), will bring more snowstorms than in 1901–2000. Agee (1991) found that long-term warming trends in the United States were associated with increasing cyclonic activity in North America, further indicating that a warmer future climate will generate more winter storms.” page. 1149
