Barack Obama, understanding the histrionics required in climate change debates, promises that U.S. emissions in 2050 will be 83 percent below 2005 levels. If so, 2050 emissions will equal those in 1910, when there were 92 million Americans. But there will be 420 million in 2050, so Obama's promise means that per capita emissions then will be about what they were in 1875. That. Will. Not. Happen.

Skeptics about the shrill certitudes concerning catastrophic man-made warming are skeptical because climate change is constant: From millennia before the Medieval Warm Period (800 to 1300), through the Little Ice Age (1500 to 1850), and for millennia hence, climate change is always a 100 percent certainty. Skeptics doubt that the scientists' models, which cannot explain the present, infallibly map the distant future.
***
The travesty is the intellectual arrogance of the authors of climate change models partially based on the problematic practice of reconstructing long-term prior climate changes. On such models we are supposed to wager trillions of dollars -- and substantially diminished freedom.
Some climate scientists compound their delusions of intellectual adequacy with messiah complexes. They seem to suppose themselves a small clerisy entrusted with the most urgent truth ever discovered. On it, and hence on them, the planet's fate depends. So some of them consider it virtuous to embroider facts, exaggerate certitudes, suppress inconvenient data, and manipulate the peer review process to suppress scholarly dissent and, above all, to declare that the debate is over.
Consider the sociology of science, the push and pull of interests, incentives, appetites and passions. Governments' attempts to manipulate Earth's temperature now comprise one of the world's largest industries. Tens of billions of dollars are being dispensed, as by the U.S. Energy Department, which has suddenly become, in effect, a huge venture capital operation, speculating in green technologies. Political, commercial, academic and journalistic prestige and advancement can be contingent on not disrupting the (postulated) consensus that is propelling the gigantic and fabulously lucrative industry of combating global warming.

With wind turbines and solar panels???? Not likely.
If your home is a typical residential electric customer, you and your family consume between 500 and 1000 kilowatt-hours of electricity per month.
With an average efficiency of 15 percent, a square yard of solar photovoltaic cells (PV) would produce (5 kilowatt-hours of solar energy multiplied by 15% =0.75 kilowatt-hours of electric energy per day. Solar panels (PV) covering an area ten yards by ten yards (100 square yards or 900 square feet) would produce 100 x .75 = 75 kilowatt-hours of electricity per day.
Seventy-five kilowatt-hours per day is a lot of electricity for a single-family home. If part of the electricity is stored in a home battery, or is used to electrolyze water for producing hydrogen gas, and the gas is stored for use by a fuel cell when needed, then 100 square yards covered with solar panels would provide an average family with energy independence. Most detached family homes have more than 100 square yards (900 square feet) of roof, or that much space around their homes where solar panels could be installed.

The proof of the failure of solar power isn’t in the Solyndra bankruptcy, but in potential BKs by industry leaders like First Solar (FSLR), the largest solar company in the world.
Since May of 2008, when First Solar reached its all-time high of $311, the company has lost 90 percent of its value, falling to $31-$33.....In the meantime CEO Robert Gillette exited stage right, with $30 million thank you from the company in October of 2011.
But he didn’t leave before First Solar received federal loan guarantees and other consideration to the tune of $3.5 billion.

...the price per kilowatt hour for solar power electrical generation at the largest scale still hovers around $.21 per kilowatt hour, according to the website Solarbuzz.com. Old-fashioned coal-fired electrical generation only cost an average of $.0821 to $.1648 per kilowatt hour in 2007 depending on region, according to figures compiled by the Energy Information Administration. And competing alternative energy sources - like wind energy - are lower cost in most regions than solar, too. Solar's costs have to still come down substantially for a long-term boom to take hold.
...three years later, the economics of green energy make as little sense as they did back then even with generous government subsidies.
The big breakthroughs in cost-savings that have been predicted for solar haven’t come - solar still costs over $.20 per kilowatt hour, although devotees are still making brave promises of future cost savings. And while many blame oversupply in solar panels for the troubles plaguing the industry, oversupply generally isn’t a problem with industries that have actual demand.

In the past trailing twelve months the company has chewed through close to three-quarters of a billion dollars in levered cash-flow. Just three months ago analysts thought the company would generate earnings per share of around $10.48 according to estimates provided by Yahoo Finance. After revisions, earnings have been slashed to a consensus estimate of $4.19 for 2012.
***
For the solar industry as a whole it’s looking less and less like a handicap and more like a terminal disease.
And if First Solar can’t make it after all the subsidized loans, state incentives, money spent on lobbying and political donations, then someone ought to ask for their money back.
Taxpayers ought to be first in line for a refund.
First Solar, Inc. – which the media sometimes identifies as the largest solar company in the world – laid off half its employees on Friday at its Antelope Valley Solar Ranch One project.
***
The cutbacks follow the announcement earlier in December that First Solar would eliminate 100 positions, including 60 at a research and development center in Santa Clara, Calif.
***
The company, like the entire solar industry, has survived on government grants and guarantees. Besides AVSR1, for example, the DOE partially guaranteed $1.46 billion in borrowing for its Desert Sunlight Solar Farm west of Blythe, Calif. And $967 million in DOE loans covered First Solar’s Agua Caliente Solar project in Yuma County, Ariz. Also, the U.S. Export-Import Bank backed $455.7 million in loans to First Solar for projects in Canada. Add millions of dollars more in manufacturing tax credits, state and local incentives, plus mandates to force utilities to buy renewable power, and you’ve got an industry that is wholly dependent on taxpayers, not on its own technology’s capabilities.
First Solar has had enough with subsidized solar markets and will bet its future on sales in countries in which solar companies that can provide low-priced equipment and engineering services will make money and stay in business, company executives said Wednesday.

This decline in cost has been driven by economies of manufacturing scale, manufacturing technology improvements, and the increasing efficiency of solar cells.

According to the City of Portland's (Oregon) web site, the cost of a solar water heater - independent of one to generate electricity - costs $6000-9000 just to heat your water Tax credits can cover half the cost.
Estimated savings is $150-300 for a family of 4. So best case scenario is approximately $3000 for installation with a savings of $300/yr for a family of four....a 10 year ROI, best case, if you spend $300/month heating water. Our entire utility bill is barely $300 some months, so the ROI is not there without a much bigger "alternative energy welfare check" to put the thing in.
Then there's electricity: tack on another $7000-9000 per KW for an electric system. A 2KW systems can save 15-20% on electricity.
We spend about $35-40 a month to heat water for a family of 5. We spend about $300/month on electricity on a large house (4200 sq ft), and I'm sure I can do some work on insulating the house better.
According to solarpowerrocks.com, they have an estimate of about $52000 for a 6kW solar installation. The ROI for their estimation is 29 years if one assumes a property value increase due to the solar power install, 36 years without it, and that assumes you stay in the house for 30 years while you pay off the 30 years loan assumed to be taken out to pay for the install. We have a gas water heater, so I have no idea if this scenario switches the water heater to the solar system or not. I'd rather have a gas water heater than a a solar-powered electric any day (I also note here that the Portland solar link mentions that solar - at least up there - won't heat water to the desirable temp in the winter.)
The numbers look to be about 3 years old based on the comments section, but I doubt the figures have gotten much better recently. Thanks, but no thanks.

More accurately, my belief is that collective action (with altruistic aims) can in many instances produce better results for all in a given nation (economy of scale often in play) than people/corporations (with self interests) acting on their own. You believe there are few such instances (defense being one). Neither philosophy is fail proof or universally better. I'm more apt to explore governmental roles and you are more apt to say people/corporations will do it best when left alone. Trouble is both approaches can be flawed. People (and corporations are not people) must keep governing bodies in line (accountability, voting) and government has to hold people/corporations in line (law enforcement, regulations). One big problem these days is that of lobbying by corporations/industrial groups or labor unions interfering with accountability, elections and the legislative process.
I know regulations can get burdensome and slow progress down at times. In this instance communication era, that can be improved upon. I'm not for throwing regulations out, just sharpening them and quickening them.
KeithE: Developing alternative energy, alternative cars is pro-choice. The US government funding of such technology (as meager as it is (see below*), compared to the $41B/year given to the fossil fuel industry in subsidies and tax breaks for decades) is justified to provide a choice of energy sources that are not (1) dependent on foreign oil, (2) cheaper than the tar sands (3x as expensive as crude oil), (3) less environmentally stressing that fracking with 29 carcinogenic/toxic chemicals involved, and (4) helps in the battle against global warming. No one is making that choice for you, ET. It may come to that if GW gets as bad as most scientists say it will at some point in the future. But that is outside your and my lifetime ET. In other words, you too could buy a Prius. You too could install solar energy if you so choose. Shutting off these technologies (in order to keep the status quo) is anti-choice.David: There is nothing whatsoever that man can do to "battle" global warming. Global warming/climate change is totally beyond man's ability to control. Global warming and climate changes are natural.

Think about it. The Medieval Warming Period, which was much, much warmer than today's temperatures, occurred when there was not a hint of the use of fossil fuels. If there is one thing constant about climate it is that it’s not constant. It’s always changing. It has always changed.

*DoE 2012 budget for alternative energy:
Vehicle technology: $0.598B
Solar energy:$0.457B
Biomass: $0.341B
Nuclear: $0.754B
Energy transformation and acceleration (smart grids): $$0.550B
That is just shy of $2B/year. And to be fair there are also loan guarantees (that sometimes go sour) and there will be tax breaks given to these industries (if their lobbyists are worth a darn). But no place near what has been given to the fossil fuel industries for decades. BTW the DoE also funds "fossil energy research" at $0.453B in 2012.
EPA funding does not handle alternative energy. It does spend $1.105B/year in Clean Air and Global Climate Change.

The largest tax break at issue is a tax credit passed in 2005, which is available to all U.S. manufacturers. Oil and gas companies qualify for that credit, so they will likely deduct somewhere in the neighborhood of $18.3 billion from their tax bill over the next 10 years. Note that this isn't really an "oil subsidy"; it's a manufacturing subsidy that oil and gas companies--along with many other companies--enjoy.
Rigging the tax code to make investments in manufacturing artificially more attractive than investments in something else is an enterprise designed to harm non-manufacturers for the benefit of ... manufacturers. Conservatives who want government to leave markets alone have no business throwing their political bodies in front of this tax break. If their political rhetoric means anything, they would see the president's bid and raise him by calling for total repeal of this tax break for everyone, not just for oil and gas companies.

---------------------------------------------- Beyond the point I made above, I'll comment on your comments ----------------------------------------------
I note that you plot one of 30 studies done by the CO2science folks. 1When you look at the data for all 30 sites (or read their summaries since not all have plots), a differing story results. For example Faroe Islands using coral core data shows higher temperatures in the current period than the MWP. But nonetheless they do make the point that the MWP may be found in more locales than just Europe. 2But overall this group seems dedicated to disproving GW (they say so), so I do not trust their objectivity.1) Contrary to the propaganda preached by the alarmists, the CO2Science folks are spot on with their data.
Here is a true reconstructed GLOBAL temperature history based on all reputable global studies
2) The CO2Science people don't attempt to disprove GW. Not at all. What they do disprove, however, is AGW (Anthropogenic Global Warming). There's a huge difference between GW and AGW. GW has occurred since the beginning of time. The alarmists falsely equate all climate change (global warming/global cooling) with AGW. As I have documented on numerous occasions, there have been scores of climate swings throughout history. There has never been a climate swing associated with human activity. Never. Period. To say that the most recent warming trend was human caused is a myth.Keith, you are incredibly misinformed about the graph below. It is not a "true reconstruction" of global temperature history. Furthermore, it's not a "reputable" graph based on "reputable" global studies. Actually, it is Wikipedia's version of the 2nd "reconstruction" of Michael Mann's original "Hockey Stick" graph. While the graph is the one most often cited by alarmists, it iscompletely bogus.
Here's the short history of the graph: The oirginal "Hockey Stick" was a creation of Michael Mann, who at the time, was working with the IPCC in an attempt to show unprecedented rapid global warming. He created this graph (Wikipedia version)) from a study of tree ring proxies. It first appeared in the Third Assessment Report (TAR-2000) of the IPCC. The graph is located at the bottom of the illustration on this page of TAR-2000.
(IPCC Fourth Assessment Report (AR4). The IPCC did post a set of graphs in AR4 that is somewhat similar to Mann's original graph, but the fact of the matter is that his graph was eliminated completely from the IPCC AR4.
The graph was so badly off the mark from reality that it was immediately discredited. On the original graph, Mann had ommited known climate science history, i.e. completely eliminating both the Medieval Warming Period (MWP) and the Little Ice Age (LIA). The IPCC received so much flak from credible climate scientists that Mann's graph was eliminated from the next IPCC Assessment Report
Since he didn't get it right the first time, Mann was forced to go back back to the drawing board with an attempt to create a graph that would include the MWP and the LIA. So he created a "Reconstructed" version of the graph. The very title ("Reconstructed") says it all. A reconstruction of an object, in this case a graph, is a remaking of the object. There would be no purpose of "reconstructing" a graph if it was right in the first place. Having failed with the original, Mann went back to the drawing board and "reconstructed" the graph and came up with this version, which still wasn't accurate or correct. While the reconstructed graph did include a MWP and LIA, it was still inaccurate because both the MWP and LIA were plotted wrong. It was wrong because the MWP was was plotted cooler than today's temperatures and the LIA wasn't plotted as as cold as as documented evidence. Check this comparison and see where Mann went wrong. The top graph is Mann's depiction whereas the lower graph is the commonly accepted historical depiction of the same period of time.
When Manns first "Reconstructed" graph was summarily discredited by credible climate scientists, he went back to the drawing board and created a second reconstruction, i.e. the one you show below. Not one of Mann's hockey stick graphs were plotted correctly. His original graph as well as both the first and second "Reconstructed" graphs are all bogus inasmuch as they incorrectly plotted. There you have it, the truth about Mann's graph reconstruction project.![]()
Note that there is good reason to say there was a MWP but note also the rapid rise since 1900 of the colored lines (the black line is an overlay of the direct temperature measurement (far more accurate and calibrated than the proxy data in colors). Note that this rise is acting against the tide of the Little Ice Age which should be lowering the temperature of earth due to the calculable Miklanovitch cycle. This rise in temp is found both in the direct temperature measurements and the proxy data.
Tree ring data is known to be inaccurate in the the current time frame (it takes 50 years or more for temperature can be deduced from a tree ring). For that reason some of the colored lines stop short of year 2000. But even these lines show a rapid increase in the face of the Little Ice Age.
It is hard to take you seriously David when you make claims that:Over the last 4,500 years, there have been at least 75 major temperature swingsI didn't make the claim that there were 75 major temperature swings. That was done by Climatologists, Cliff Harris and Randy Mann, creators of the graph. Your argument is with them, not me.
and you click on the cartoon of a picture that shows only 5 (maybe 6) temperature swings.
Their "75" swings may be 75 volcanoes not major temperature swings. There is no indication that the line drawn is actual data.And there is no indication on a single one of Mann's bogus graphs that his lines are actual data... In fact, Mann has never released records of his data to the public. Steve McIntyre and Ross McKitrick have been trying for more than a decade to get Mann to release the data to his hockey stick. Thus far, he has flatly refused to do so.
It is hard to take even this plot seriously when they say Mt. Pinatubo eruption caused a 1.1F drop from June 1991 to March 1992 when the data says is only fell slightly:
Hadley DATA: 0.269C in June 1991 and 0.199C in March 1992 = 0.07 C = 0.126F not 1.1F Source
GISS DATA: 0.49C in June 1991 and 0.39 in March 1992= 0.10C = 0.18F not 1.1F SourceNeither the Hadley Data (Phil Jones' outfit) nor the GISS Data (James Hansen's outfit) are credible sources. Data from both Hadley and GISS have been proven to be manipulated.
I'd show Spencer's DATA but he does not make that conveniently available before 1998 (I wonder why? the MSU/AMSU data started in 1979).
Easterbrook is wrong as well which I'll show after Church sometime today. Quoting a known denialist who is merely asserting something w/o DATA does not make any case at all. It very well could be that Easterbrook counted noise fluctuations. I'll also show the relative contributions from volcanoes, solar activity and ghgs and the fact that when volcanoes/solar variations/ENSO effects are taken into account, the temperature due to all other factors (most of which are human caused) has continued to rise even in the 2000's.Call him a "denialist" or whatever, Easterbrook is correct. You can deny his acuracy and be a "denialist" yourself, but I'm sticking with the credible scientists with 50 years of experience in the business...
There is nothing whatsoever that man can do to "battle" global warming. Global warming/climate change is totally beyond man's ability to control. Global warming and climate changes are natural.
